The second generation of the mid-range SUV from Mercedes-Benz goes by the name of GLC and represents a big step forward on several fronts: On a technical level the new SUV clearly makes its mark with the excellent standard of safety that is a brand hallmark, featuring state-of-the-art assistance systems and outstanding energy efficiency. Fuel consumption has been cut by up to 19 per cent in comparison to the previous model. At the same time, the AIR BODY CONTROL multi-chamber air suspension that is without parallel in this segment, the extended range of DYNAMIC SELECT dynamic transmission modes and the 4MATIC permanent all-wheel drive increase not only the ride comfort, but also the vehicle’s sporty agility – whatever surface it is driving on. Visually, the body follows the clear and sensual design idiom which was demonstrated so successfully by the GLC Coupé showcar concept in the spring, and which serves as the standard for future SUV families.
“Our new GLC represents a further, systematic step in the implementation of our successful SUV philosophy. It combines the ultimate in driving comfort with a sporty touch, impresses on the road and – more than ever – off it as well, and appeals to the eye with the new design and equipment line,” says Thomas Weber, member of the Management Board of Daimler AG and responsible for Group Research and Mercedes-Benz Cars Development.
The design philosophy behind the new GLC essentially favours sensual purity and a modern aesthetic over the classic off-road look. The dynamic design exudes emotional appeal while also employing purist forms. Surfaces embodying a degree of tension and precise lines cite the clear design line followed by all state-of-the-art SUVs from Mercedes-Benz. The GLC only represents a departure from its progenitor – the G-Class – in terms of appearance, however. On a technical level it sets new benchmarks in all disciplines – the mid-size SUV’s off-road capabilities remain as outstanding as ever.
2016 Mercedes-Benz GLC
The characteristic SUV front with a short, succinct overhang, upright, three-dimensional radiator grille with a twin louvre and centrally positioned brand star follows the successful new design line. Striking headlamps, optionally available as LED High Performance lamps, lend the GLC a self-confident look which is further emphasised by their distinctive night design. The bumpers with integrated underguard come in three variants: in addition to the base version there is a version optimised for off-road use with a larger angle of approach/departure, plus a particularly sporty AMG variant.
The side view showcases the almost coupé-like greenhouse, which together with the 118 millimetres larger wheelbase lends the GLC an elegant long profile. This impression is further reinforced by the gently sloping dropping line which is a hallmark of the brand and by the powerful shoulders. The rising lower feature line also enlivens the vehicle’s side view. Matt black cladding in the wings, wheels up to a size of 50.8 cm (20 inches) and the optional side running board provide clear indications of the GLC’s off-road credentials.
The rear is characterised by the broad, muscular shoulders, the horizontal orientation of the contour lines and the split LED rear lamps featuring a distinctive night design. As on the front, the different bumper variants are available here as well. By integrating all the antennae into the exterior mirrors and the roof spoiler, it has been possible to do away with the fin which has featured on the roof to date.
GLC interior: added class
The paradigm shift in the area of design affects not only the outside appearance. The model change also signals a marked upgrade for the interior. A modern setting prevails which is quite in keeping with the standard set by its bigger brother, the GLE. The new design idiom combines sensual purity with dynamic sportiness and embodies a new interpretation of modern luxury. The GLC’s interior conjures up the feel-good atmosphere which is a brand hallmark courtesy of high-class materials featuring a hand-crafted character, such as nappa leather or open-pore wood trim, meticulously finished details and an appealing overall touch and feel. Last but not least, substantially more space is available for occupants and luggage. The optional large-area panoramic glass roof further enhances the light and airy feel inside.
A key focus of the totally new interior design is the dashboard and the centre console with its flowing lines, with a large, one-piece console panel performing an elegant sweep from the centre air vents to the armrest. These clear-cut lines create a feeling of open space and establish a purist, modern vibe. The newly developed innovative touchpad in the handrest over the rotary pushbutton nestles ergonomically in the centre console. As on a smartphone, this provides for very simple and intuitive operation of all the head-unit functions using finger gestures. The touchpad also permits letters, numbers and special characters to be entered in handwriting – in any language supported by Audio 20 or COMAND Online. A centrally positioned media display is partially integrated above the centre console. Five round air outlets with metallic “cool touch” effect lend the dashboard a sporty air and create an interesting contrast to the warm look of the other materials.
More space, more fun, more comfort
In comparison to its predecessor, the new model is substantially more spacious for front and rear occupants alike. The increase in the GLC’s length in comparison to the previous model has been translated effectively into useful interior space. Almost all key comfort factors have been improved – substantially in some instances – above all the space on the rear bench.
Another comfort criterion – entry and exit space for the rear passengers – has also been enhanced substantially, with 34 millimetres more foot space now available for the purposes of entering and exiting the vehicle.
Through the effective use of space and intelligent packaging, the engineers have also managed to increase the size of the luggage compartment with level a load area and its attendant utility value substantially. The rear bench features a 40/20/40 split and offers a cargo position which increases the load capacity by locking the backrests at a steeper angle. The load capacity behind the rear bench increases by 80 to 110 litres, to a total of up to 580 litres. In all, the GLC 1600 is able to transport up to 1600 litres – 50 litres more than was previously possible. The maximum luggage compartment length is 1320 millimetres, while the maximum width increases by 150 to 1100 millimetres.
Added convenience for loading and unloading is provided by lowering of the load compartment sill by 40 mm with the AIR BODY CONTROL option and by HANDS FREE ACCESS, which enables the tailgate to be opened automatically by performing a swiping movement with the foot under the bumper.
Energy efficiency: crucial parameters
Mercedes-Benz has applied an extensive package of measures to enhance the GLC’s energy efficiency and performance substantially. Modified or new drive systems, outstanding aerodynamics and intelligent lightweight design are the primary factors behind the vehicle’s fuel efficiency. The diesel and petrol models boast significant reductions of up to 19 per cent in both fuel consumption and CO2 emissions in comparison to the previous generation, while at the same time improving performance with the same power output.
All models comply with the EU6 emissions standard and offer a start/stop function. For the first time in this segment, with the GLC 350 e 4MATIC Mercedes-Benz is additionally offering a plug-in hybrid which combines the merits of agile all-wheel drive with the lowest fuel consumption and emissions: the mid-size SUV emits only 60 g of CO2 per km and attains a top speed of 146 mph with a best-in-class system output of 211 + 116 hp.The semi-electric vehicle can cover up to 21 miles in zero-emission all-electric mode, accelerating to 62 mph in 5.9 seconds if necessary, courtesy of the boost function. Like its plug-in big brother of the S-Class, the GLC 350 e 4MATIC offers all the characteristic comfort and efficiency systems – from the flexible, intelligent operating strategy through the specific hybrid driving programs and the haptic accelerator pedal to pre-entry climate control.
The design transition has also bestowed superlative aerodynamics on the new GLC. With a Cd value of 0.31 (GLK 0.34) and total aerodynamic drag of 0.794 (GLK 0.87), it sets a clear benchmark in this segment. Apart from the vehicle’s substantially more aerodynamically efficient basic shape, this exceptional aerodynamic performance also results from a host of solutions relating to points of detail, such as sealing of the radiator and headlamp surrounds, a radiator shutter, the extended roof spoiler or the optimised underbody panelling.
Despite markedly larger outer dimensions, a longer wheelbase and a more extensive scope of equipment, the vehicle’s weight has been cut by 80 kilograms. The main contributory factor to this reduction is the totally new body, which is 50 kilograms lighter than the smaller GLK counterpart, thanks to an intelligent mix of materials comprising aluminium and high- to ultra-high-strength steels. Aluminium components additionally reduce the weight of the chassis, which also benefits ride comfort due to the attendant reduction in unsprung masses. The optional AIR BODY CONTROL full-support multi-chamber air suspension features spring elements in lightweight yet robust glass-fibre-reinforced plastic, which reduce the system weight in comparison to conventional air suspensions. The use of the new compact transfer case as an add-on module and the 9G-TRONIC with its magnesium transmission housing results in a reduction in weight of 12 kg in comparison to the previous model.
AIR BODY CONTROL: innovative air travel
The new GLC features the AGILITY CONTROL suspension with steel springs and a variable damping system as standard. The GLC is the sole model in this market segment to offer the option of fitting the chassis with a full-support multi-chamber air suspension system and electronically controlled, continuously adjustable damping. The AIR BODY CONTROL suspension combines excellent driving stability and sporty agility with optimum comfort and outstanding off-road capabilities. Specific characteristics are pre-selected according to the settings of the DYNAMIC SELECT driving dynamics program. In Sport mode the GLC’s occupants feel as if they are sitting in a sports car with a high level of lateral dynamics due to the tauter connection of the chassis, which is additionally lowered by 15 millimetres. Comfort mode offers the very opposite ride experience, focussing on particularly comfortable running with soft connection of the chassis. To ensure maximum driving safety in this mode, too, the spring and damper forces adapt within 60 milliseconds in response to sudden evasive manoeuvres, for example. When the GLC is equipped with the Off-Road Engineering package, AIR BODY CONTROL optimises the wheels’ ground contact, ensuring good progress in off-road terrain by raising the driving level by up to 50 mm and providing for particularly soft basic tuning. Further benefits of the system include reduced rolling during cornering, automatic level control and lowering of the load compartment sill for convenient loading and unloading.
Powertrain: agility, dynamism and comfort à la carte
The new GLC offers the DYNAMIC SELECT handling control system with five driving programs as standard. In addition to the ECO, COMFORT, SPORT, SPORT+ and INDIVIDUAL settings which are familiar from other models, the new all-rounder can also be equipped with the Off-Road Engineering package. This comprises up to five programs. “Slippery” and four off-road driving programs are totally new here. “Off-road” is predestined for easy off-road terrain such as gravel or sand tracks. “Incline” boosts climbing capabilities on steep ramps or long, slow uphill stretches. In conjunction with AIR BODY CONTROL air suspension, the additional “Rocking Assist” program offers the last resort, should the vehicle get stuck. Here the driving level is raised by 50 millimetres and the wheel-slip control thresholds are increased so as to enable the GLC to work its way free. The fourth off-road program, “Trailer”, is designed for optimum trailer towing off-road and facilitates moving off on wet grassland, for example. The Off-Road Engineering package further includes a robust Gemtex underride guard, which takes the stress out of heavy ground contact as on the previous model, and Downhill Speed Regulation. The system, which goes by the abbreviated name of DSR, automatically maintains the speed which has been pre-set on the cruise control on steep downhill stretches.
All DYNAMIC SELECT programs are visualised on the central media display. Especially impressive are the off-road animations: various parameters, such as incline, steering angle or heading are presented in dynamic mode in real time on the central media display.
All models feature 4MATIC permanent all-wheel drive with a basic drive torque split of 45 to 55 percent between front and rear axle. In cooperation with the ESP®, ASR and 4ETS dynamic handling control systems, this provides for superior and clearly predictable handling. The multiple-disc clutch in the centre differential assists the system in the event of really low friction coefficients between tyre and road, for example on snow or ice. A basic locking force of 50 Nm between the front and rear axles brings about a significant increase in traction with the same high level of driving stability.
The nine-stage 9G-TRONIC automatic transmission also comes as standard on the GLC 220 d 4MATIC, GLC 250 d 4MATIC and GLC 250 4MATIC. Depending on the mode selected for the DYNAMIC SELECT dynamic handling control, the automatic transmission with a torque converter boasts great agility and responsiveness or poised composure. The potential of the transmission is exploited to the full. It offers an impressively high shift speed and perfect transitions for energetic sprinting as well as with gentle, barely perceptible gear changes for enjoyable cruising. As with all hybrid models from Mercedes-Benz, the GLC 350 e 4MATIC is equipped with the latest version of 7G-TRONIC PLUS, which has been specifically optimised in line with the needs of hybrid applications and also combines high driving dynamics with excellent drive comfort and superior efficiency.
Mercedes-Benz Intelligent Drive: guardian angels on board
Almost all of the driver assistance systems which are familiar from the C-, E- and S Class are available for the new GLC. As part of the Intelligent Drive concept, these systems combine data from various sensor technologies to enhance comfort and safety substantially. COLLISION PREVENTION ASSIST PLUS, Crosswind Assist, Headlamp Assist and ATTENTION ASSIST are on board as standard. The Driving Assistance package Plus provides an even more comprehensive scope of active safety features, comprising DISTRONIC PLUS with Steering Assist and Stop&Go Pilot, PRE-SAFE® Brake with pedestrian detection, BAS PLUS with Cross-Traffic Assist, Active Blind Spot Assist, Active Lane Keeping Assist and PRE-SAFE® PLUS. The latter feature also offers added protection in the event of a rear-end collision. By means of a radar sensor in the rear bumper PRE-SAFE® PLUS identifies impending rear-end collisions, alerts the traffic behind by operating the hazard warning lights at a particularly eye-catching flashing frequency, activates preventive occupant protection measures and brakes the vehicle to a standstill after a rear-end collision to reduce the levels of stress acting on the occupants. Greater safety for all road users is provided by Traffic Sign Assist with its wrong-way warning function, which in addition to speed limits can also alert the driver to no-overtaking and no-entry signs. On vehicles equipped with the LED Intelligent Light System, Adaptive Highbeam Assist Plus allows main beam to be left on permanently by masking out the area of the main-beam light cone which is occupied by other vehicles. Simpler handling and a clearer view when manoeuvring in tight spaces or driving in dense urban traffic are ensured by the 360° camera, which is able to show the vehicle and its surroundings from different perspectives, and by Active Parking Assist, which manoeuvres the vehicle fully automatically into detected parallel and end-on parking spaces.
The improved ergonomics and simpler controls in the GLC also help to enhance safety. All important vehicle functions and settings can be carried out intuitively using the central rotary pushbutton or the touchpad. The desired settings or information are visualised by the large, partially integrated colour media display in the middle of the dashboard. Direct selection buttons next to the light switch module to the left of the steering wheel additionally enable direct activation of the most important assistance systems.
Also new is the Head-up Display, (HUD). The HUD displays important information directly in the driver’s field of vision on the front windscreen, thus providing for clear legibility and less distraction from the road ahead. The system provides information on speed, posted speed limits, navigation instructions and messages from the DISTRONIC system.
Airbag & co.: cushioning protection for the occupants
In keeping with the Mercedes-Benz tradition, the body forms the foundation for exemplary crash safety. A high-strength safety passenger compartment forms the core of this concept. It is surrounded by specifically designed and field-tested deformation zones, which ensure maximum safety for the occupants by virtue of optimised force paths and a combination of die-cast aluminium components and ultra-high-strength materials.
In addition to 3-point safety belts with pyrotechnical and reversible belt tensioning and belt-force limitation for driver, front passenger and those in the outer rear seats, numerous airbags serve to protect the vehicle’s occupants in an accident. These include the combined thorax/pelvis sidebags for driver and front passenger and a newly developed windowbag extending over both seat rows, the optional sidebags for the outer rear seats and a driver kneebag.
The front passenger seat can additionally be fitted with automatic child seat recognition, which dispenses with the previous transponder in favour of a weight mat. This enables any child seat to be used. The airbag is automatically deactivated when a child seat is fitted and reactivated once it has been removed.
The full spectrum: model range and equipment
Four models are available at the market launch of the GLC, all featuring 4MATIC permanent all-wheel drive as standard:

In addition to the standard functions such as eCall, accident recovery, breakdown assistance or after-sales service, the Remote Online app offers numerous convenience features via smartphone, such as tracking to locate the parked vehicle, control of the auxiliary heating, locking and unlocking of the vehicle or the retrieval of various items of status information, such as mileage, fuel level or range.
Comfort and space – More space, more fun, more comfort
In comparison to its predecessor, the new GLC is substantially more spacious for front and rear occupants alike. The increase in the size of the GLC in comparison to the previous model has been translated effectively into useful interior space. Almost all key comfort factors have been improved – substantially in some instances – above all the space on the rear bench, which came in for frequent criticism on the previous model. An impressive amount of legroom – the space between the front seat backrests and the rear bench seat – is now available, following a very sizeable increase of 57 millimetres.
More space is also available for the front occupants, who benefit from a generous increase in shoulder and elbow room. By means of intelligent packaging and perfect seat geometry, the interior designers from the Mercedes-Benz Technology Centre (MTC) have even managed to conjure up 57 millimetres of additional space here – although the vehicle’s width has only grown by 50 millimetres.
Another comfort criterion – entry and exit space for the rear passengers – has also been increased substantially, with 34 millimetres more foot space now available for the purposes of entering and exiting the vehicle.
Growth strategy applied to maximum effect
Through the effective use of space and intelligent packaging, the engineers have also managed to increase the size of the luggage compartment with a level load area and its attendant utility value substantially.
Added convenience for loading and unloading is provided by lowering of the load compartment sill in conjunction with the AIR BODY CONTROL option and by HANDS-FREE ACCESS, which enables the tailgate to be opened automatically by performing a swiping movement with the foot under the bumper.
NVH: no noise, no vibration, no harshness
In order to assess the aeroacoustics, which represent the crucial comfort parameter particularly at higher speeds, the development engineers examined the GLC’s psycho-acoustic properties. In addition to the high-frequency wind noise, the low-frequency components and, in particular, speech intelligibility are considered and optimised here. In their development work, the engineers devoted special attention to the air flow around the body of the vehicle, the sealing systems at doors and windows and the bodyshell. The focus in this work is not solely on the absolute sound pressure level (dB(A)). Rather, the onus is on creating the most homogeneous, harmonious possible overall acoustics. This means that neither certain frequency ranges nor individual components or areas of the vehicle must be allowed to play a dominant role. From a speed of around 120 km/h, wind noise is the dominant acoustic factor, while tyre and engine noise play a less important role. A comparison with the E-Class shows how successfully the aeroacoustics engineers have “tuned” the GLC. The wind noise index, WI – a dimensionless figure to classify aeroacoustic quality – is at the same pleasant level in both objective and subjective terms.
In addition to an increase in the vehicle’s overall rigidity, another key focus of development work was on connection of the chassis and drive system to the body, as high introduction rigidity of the mounting points is essential in order to tune the bearing elements so as to minimise the noise level. The development engineers at the Mercedes Technology Centre have pulled out all the stops here and achieved a further marked reduction in noise and vibration. In addition to the aeroacoustic measures, the following components and design details are also conducive to noise and vibrational comfort:
Low noise input into the interior as a result of the intelligent use of sprayable acoustic compositions in the body-in-white, major assemblies compartment partition made of fibre-reinforced plastic with absorber, firewall insulation with high-quality injection moulded component
Rigid front-end design with diagonal struts and a new front module concept consisting of an extruded section and cast aluminium/plastic consoles with additional struts. To date, this design has only been applied for cabriolets, which entail special requirements in this area.
Rigid cockpit cross-member consisting of high-strength magnesium alloy
Electromechanical Direct-Steer system with optimised housing rigidity and body connection reduces steering and tyre noise.
Highly sound-absorbent acoustic windscreen, acoustic front side windows optionally available
Three-point engine mounting damps resonant vibrations and reduces the forces introduced into the body
Body floor with reinforced tunnel, additional beading and reinforcements in the area of connection of the transmission; reduces tyre noise and eliminates vibration of the main floor and the attendant noise radiation
High rigidity of the rear area due to the use of cast aluminium components
Reduction in unsprung masses as a result of weight-optimised aluminium components and the use of glass-fibre-reinforced spring elements when AIR BODY CONTROL air suspension is fitted
Minimal torsional vibration due to centrifugal pendulum and double turbine damper (9G-TRONIC) or double torsional damper (7G-TRONIC PLUS on the 350 e 4MATIC)
Driving enjoyment, on- and off-road: Dynamism, agility and ride comfort à la carte
Featuring a totally new chassis and suspension, the new GLC clearly surpasses its predecessor’s performance. Numerous design measures have led to a further improvement in suspension and ride comfort accompanied by excellent driving dynamics and agility. Key measures here include the switch from a three-link to a four-link front suspension, the increased track width at front and rear and the larger tyre sizes of up to 50.8 cm (20 inches). The elastokinematics have also been optimised and the use of numerous aluminium components on the front axle and the five-link rear axle has resulted in weight savings while at the same time enhancing stability.
The GLC offers an AGILITY CONTROL suspension with steel springs and variable damping system as standard, optionally available with an emphasis on sporty performance, comfort or off-road performance:
The base version features the comfort suspension, an accomplished synthesis of sporty directness and superior suspension comfort
In combination with the AMG Exterior Line or as an individual option, a sports suspension based on the AGILITY CONTROL suspension is available, with harder springing and a reduced roll tendency
The GLC 350 e 4MATIC model and vehicles equipped with the Off-Road Engineering package feature a 20 millimetre higher driving level as standard for added ground clearance.
AIR BODY CONTROL with ADS Plus: innovative air travel
The GLC is the sole model in this market segment to offer the option of fitting the chassis with a full-support multi-chamber air suspension system and the electronically controlled, continuously adjustable adaptive damping system ADS Plus. This configuration combines excellent driving stability and sporty agility with optimum comfort and outstanding off-road capabilities. Specific characteristic are pre-selected according to the settings of the DYNAMIC SELECT driving dynamics program.
In SPORT+ mode the GLC’s occupants feel as if they are sitting in a sports car with a high level of lateral dynamics due to the tauter connection of the chassis, which is additionally lowered by 20 millimetres. Comfort mode offers the very opposite ride experience, focussing on particularly comfortable running with soft connection of the chassis. To ensure maximum driving safety in this mode, too, the spring and damper forces adapt within 60 milliseconds in response to sudden evasive manoeuvres, for example. When the GLC is equipped with the Off-Road Engineering package, AIR BODY CONTROL optimises the wheels’ surface contact, ensuring good progress in off-road terrain, by raising the driving level by up to 50 mm and providing for particularly soft basic tuning.
Further benefits of AIR BODY CONTROL include reduced rolling during cornering, automatic level control and lowering of the load compartment sill for convenient loading and unloading.
A perfect match: DYNAMIC SELECT and Off-Road Engineering package
The new GLC offers the DYNAMIC SELECT handling control system with five driving programs as standard:
ECO – places the emphasis on energy-efficient driving, with sailing function and ECO display in support of the most fuel-efficient driving style
COMFORT – well-balanced driving program, with comfortable suspension tuning, fuel-efficient set-up for the drive system
SPORT – more direct response of engine and automatic transmission and a more progressive steering characteristic support a sporty driving style, additionally taut, sporty suspension configuration in conjunction with AIR BODY CONTROL and ADS Plus
SPORT+ – even more direct response for maximum longitudinal and lateral dynamics
INDIVIDUAL – configuration of the driving experience according to personal preferences, within the bounds of combinations providing for safe and effective driving dynamics The COMFORT, SPORT and ECO settings for drive system, suspension and steering can be activated and combined according to personal preferences.
All DYNAMIC SELECT programs are visualised on the central media display.
In addition to the standard-fit DYNAMIC SELECT dynamic handling control, the new all-rounder GLC can be combined with the Off-Road Engineering package and the AIR BODY CONTROL air suspension. In all, five programs are then available: Slippery, Trailer, Off-road, Incline and Rocking Assist. The characteristics in detail:
Off-road – easy terrain such as dirt roads, gravel or sand tracks, driving level is raised by 15 millimetres
Incline – optimises the GLC’s climbing capabilities, driving level is raised by 15 mm
Rocking Assist – the ideal remedy, should the vehicle become stuck. Ground clearance is raised by 50 millimetres, the wheel-slip control thresholds are increased to enable the vehicle to work its way free. Active up to 20 km/h. Automatic switch to the Off-road program at speeds above this.
Slippery – ideal for low friction values, such as apply on muddy surfaces, wet grassland, on slippery snow or ice and when using snow chains
Trailer – facilitates manoeuvring with a trailer in adverse conditions, for example on wet grassland or on a boat ramp (only in conjunction with trailer coupling)
The Off-Road Engineering package additionally includes a robust Gemtex underride guard, which takes the stress out of heavy ground contact as on the previous model. Downhill Speed Regulation (DSR) is also included for controlled downhill driving. The driver can pre-set a speed using the cruise control lever. This set speed is then maintained automatically on downhill stretches, without any need to operate the brake pedal.
As with the other DYNAMIC SELECT programs, the Off-road animations are also presented on the central media display. Various parameters, such as incline, tilt angle, steering angle, heading or the AIR BODY CONTROL settings, are displayed dynamically in real time.
4MATIC permanent all-wheel drive:the prime mover for excellent driving dynamics
The nine-stage 9G-TRONIC automatic transmission also comes as standard on the GLC 220 d 4MATIC, GLC 250 d 4MATIC and GLC 250 4MATIC. Depending on the mode selected for the DYNAMIC SELECT dynamic handling control, the automatic transmission with torque converter boasts great agility and responsiveness or poised composure. The potential of the transmission is exploited to the full. It offers an impressively high shift speed and perfect transitions for energetic sprinting as well as with gentle, barely perceptible gear changes for enjoyable cruising.
The development engineers have fully revised the design of 4MATIC permanent all-wheel drive in combination with 9G-TRONIC. In contrast to the former configuration, the single-stage transfer case is no longer integrated into the automatic transmission, but rather flange-mounted on the 9G-TRONIC as a separate system. This “add-on” solution combines the advantages of both concepts and results in increased efficiency. The new all-wheel-drive powertrain features the same compact design as with the previous, integrated solution, offers 50 newton metres of pre-lock torque and allocates the drive torque to the front and rear axles with a 45:55 split via a planetary differential. The add-on design also offers the following advantages:
Enhanced performance – use of particularly torquey engines possible
Separate oil circuits – lubricant properties tailored specifically to the 9G‑TRONIC and the transfer case, resulting in less wear and enhanced NVH comfort as a result of reduced friction loss
Weight advantage – magnesium housing of the 9G-TRONIC is retained with the add-on solution, resulting in weight savings of around 12 kilograms for the overall system compared to the integrated variant with aluminium housing which was employed on the previous model.
Improved system efficiency – as a result of the reduced weight, the lower friction loss, the broad gear ratio spread of the 9G-TRONIC and the resultant longer axle ratios
As with all hybrid models from Mercedes-Benz, the GLC 350 e 4MATIC is equipped with the latest version of 7G-TRONIC PLUS, which has been specifically optimised in line with the needs of hybrid applications and also combines high driving dynamics with excellent drive comfort and superior efficiency.
Energy efficiency – Economy on four wheels
A revised all-wheel-drive powertrain, the outstanding aerodynamics and the intelligent lightweight design are the primary reasons for the high energy efficiency of all the new GLC models. The conventional diesel and petrol models boast significant reductions of up to 19 percent in both fuel consumption and CO2 emissions in comparison to the previous generation, while at the same time improving performance.
Mercedes-Benz is also offering a plug-in hybrid for the first time in this market segment: The GLC 350 e 4MATIC boasts minimal fuel consumption and emissions while offering performance on a par with that of a sports car. It is also the first plug-in hybrid in this market segment with permanent all-wheel drive, which also performs convincingly off-road. This version supersedes the previous GLK 350 4MATIC model with a conventional petrol engine and similar performance data.
In addition, the GLC 350 e 4MATIC can cover up to 34 km in zero-emission all-electric mode, with a top electric speed of 140 km/h. And thanks to optimised integration of the plug-in technology it furthermore offers outstanding cargo space for a plug-in hybrid, at 350/1445 litres.
Just like its plug-in big brother in the S-Class, the GLC 350 e 4MATIC offers all the characteristic comfort and efficiency systems. The most important facilities at a glance:
Silent start: the vehicle starts virtually silently and runs in electric mode. At this point the combustion engine is generally kept switched off.
Boosting: The electric motor kicks in to boost the output of the combustion engine by up to 85 kW, turning the GLC 350 e 4MATIC into a sports car. Acceleration from 0 to 100 km/h takes only 5.9 seconds.
Energy recuperation: during braking and coasting, energy is recovered and stored in the battery. This energy can then be used at a later stage for electric driving or the boost function.
Haptic accelerator pedal: Supports fuel-efficient driving. A resistance point indicates the maximum available electric output. A double impulse signals that the driver should remove their foot from the accelerator pedal in order to switch off the combustion engine and decouple it from the drive train.
Intelligent HYBRID: Intelligent operating strategy for hybrid vehicles, anticipates the course of the road and the traffic situation for maximum efficiency. This includes radar-based recuperation, an anticipatory shifting and operating strategy, a route-based operating strategy and the ECO Assist.
Pre-entry climate control: The desired interior climate can be set before starting your journey – cooling in the summer, heating in the winter. This function can be activated via a pre-set departure time or via smartphone using the Mercedes-Benz connect me app.
Retrieval of vehicle status: It is additionally possible to control the charging process or to check the charge status and the current electric range via the Mercedes-Benz connect me app
The GLC 350 e 4MATIC offers four basic operating modes which are available in the DYNAMIC SELECT driving programs ECO and COMFORT:
Hybrid: All hybrid functions, such as electric mode, boost and recuperation are available and are deployed for optimum fuel efficiency.
E-mode: used for all-electric driving – for example in inner-city areas or because the battery holds sufficient charge for the remainder of the journey.
E-Save: the charge status of the battery is maintained – for example to allow all-electric driving in an environmental zone at a later stage in the journey.
Charge: Serves to charge the battery via the combustion engine while on the move, to enable all-electric driving in an environmental zone at a later stage in the journey, for example.
Intelligent lightweight design for slimline results
Another key factor behind the vehicle’s economic efficiency is the weight-shedding programme that the GLC has undergone. Despite markedly increased exterior dimensions, a longer wheelbase and a broader scope of equipment, the vehicle’s weight has dropped by 80 kilograms. The main contributory factor here is the totally new hybrid material body, which introduces innovative lightweight design into volume production. As a result of the intelligent mix of materials spanning aluminium, high- to ultra-high-strength steels and robust plastic, the foundation of the GLC is 50 kilograms lighter than its substantially smaller predecessor – while at the same time rigidity has been increased for excellent handling, noise and vibration comfort has been optimised and crash safety has been further enhanced.
The following aluminium components are used:
Front wing, bonnet and roof panelling
Front: Front end (extruded aluminium section), crash boxes, frames for fitting headlamps, cooling system and bonnet closing system
Shock absorber strut consoles (die-cast aluminium) to house the front struts
Rear area with shock absorber strut consoles, cross-members and longitudinal members (die-cast aluminium)
Door hinges
4×4 integral support for front axle and steering, rear axle carrier
Suspension: Four-link front suspension with spring link, strut rod, upper wishbone and steering knuckle (forged aluminium), five-link rear axle and wheel carrier (forged aluminium). This lowers the weight of the rear axle by 5 kilograms, while also improving its stability.
Weight-shedding measures also apply to the air suspension elements of the AIR BODY CONTROL system, which consist of glass-fibre-reinforced plastic. The aluminium and plastic components of the chassis and suspension not only reduce the weight but also enhance ride comfort as a result of the attendant reduction in unsprung masses.
Other weight advantages result from the 4MATIC all-wheel-drive powertrain with the nine-stage automatic 9G-TRONIC featuring a magnesium housing. Weight savings of around 12 kilograms are attained here. Highly robust body components made of plastic are also used. The front major assemblies compartment partition is one such component.
Streamlined transition
The design transition has also bestowed superlative aerodynamics on the new GLC, which sets a clear benchmark in this SUV class with a Cd value of 0.31 (GLK 0.34) and total aerodynamic drag of 0.794 (GLK 0.87). Apart from the vehicle’s substantially more aerodynamically efficient basic shape, this exceptional aerodynamic performance also results from a host of solutions relating to points of detail:
Cooling air controlled according to installed engine variant, with ring-type shutter
Improved sealing of the radiator section and flow properties to make efficient use of the available cooling air
Streamlined design of the front and rear aprons
Sealed headlamp surrounds
Three-dimensional front wheel spoilers with patented slotted wheel arch linings for optimised air flow around the wheels
Aeroacoustic and aerodynamic design of the A-pillar
Extended roof spoiler with optimised flow properties and joint seals
Aerodynamically optimised underbody with extensive engine compartment and underbody panelling
Aerodynamically optimised wheels and tyres
Safety – SUV stands for safety and responsibility
Virtually all of the driver assistance systems which are familiar from the C-, E- and S-Class are available for the new GLC. As part of the Intelligent Drive Concept, these systems combine data from various sensor technologies to enhance comfort and safety substantially. COLLISION PREVENTION ASSIST PLUS, Crosswind Assist, Headlamp Assist and ATTENTION ASSIST are on board as standard. Driving Assistance package Plus provides an even more comprehensive scope of active safety features, comprising DISTRONIC PLUS with Steering Assist and Stop&Go Pilot, PRE-SAFE® Brake with pedestrian detection, BAS PLUS with Cross-Traffic Assist, Active Blind Spot Assist, Active Lane Keeping Assist and PRE-SAFE® PLUS. The latter also offers added protection in the event of a rear-end collision, as by means of a radar sensor in the rear bumper it is able to detect an impending rear-end collision and initiate special protection measures and warning functions.
Greater safety for all road users is provided by Traffic Sign Assist with wrong-way warning function, which in addition to speed limits can also alert the driver to no-overtaking and no-entry signs. On vehicles equipped with the LED Intelligent Light System, Adaptive Highbeam Assist Plus allows main beam to be left on permanently by masking out the area of the main-beam light cone which is occupied by other vehicles.
The key functions of the assistance systems on board the GLC
Comfort-oriented assistance
DISTRONIC PLUS with Steering Assist – helps to keep the vehicle in its lane and is capable of following tailbacked traffic in semi-autonomous mode
Safety – linear guidance
COLLISION PREVENTION ASSIST PLUS – can help to prevent rear-end collisions
BAS PLUS – can also detect crossing traffic and pedestrians and boost the braking power applied by the driver, thereby reducing the severity of an accident
PRE-SAFE® Brake – can detect pedestrians, avoid collisions with pedestrians or stationary vehicles by means of autonomous braking at vehicle speeds of up to 50 km/h and reduce the severity of collisions at speeds of up to 72 km/h
Safety – towards the rear
PRE-SAFE® PLUS – can detect impending rear collisions, initiate PRE‑SAFE® occupant protection measures when a rear collision is imminent and lock the brakes of the stationary vehicle in a rear collision in order to reduce the loads acting on the occupants and to avoid secondary collisions
Safety – lateral guidance
Active Kane Keeping Assist – can detect oncoming traffic and whether the adjacent lanes are occupied, and prevent the vehicle from leaving its lane unintentionally by applying the brakes on one side
Safety – at night
Adaptive Highbeam Assist Plus – allows the main-beam headlamps to be kept on permanently without dazzling traffic by masking out other vehicles in the beams’ cone of light.
Off-road lights – specific off-road headlamp settings for broader illumination of the terrain ahead, improve orientation in off-road terrain
Safety during parking and manoeuvring
Active Parking Assist – can manoeuvre into and out of parallel and end-on spaces with automatic steering
Driver attentiveness and fitness
ATTENTION ASSIST – can warn of inattentiveness and drowsiness in an extended speed range from 60 to 200 km/h and inform the driver about their level of drowsiness and how long they have been driven since their last break
All-round visibility in the GLC
In addition to Active Parking Assist, simpler handling and a clearer view when manoeuvring in tight spaces or driving in dense urban traffic are ensured by the 360° camera, which is able to show the vehicle and its surroundings from different perspectives. Functions of the 360° camera in detail:
The virtual bird’s-eye view shows an aerial view of the GLC and the surrounding area three metres to the front and rear and 2.5 metres to the sides of the vehicle.
Display of perspectives which are not actually physically possible. For example, when manoeuvring in a multi-storey car park with a low ceiling a bird’s-eye view of the GLC and its surroundings are shown from a height of over three metres, although the ceiling is actually only a few centimetres above the vehicle.
Visualisation of the sides of the vehicle and its surroundings to avoid knocks to the exterior mirrors or the wheel rims, for example.
Visualisation of obstacles below the vehicle’s belt line, which are not visible to the driver.
Visualisation of crossing traffic in front of and behind the vehicle when manoeuvring out of tight parking spaces or in tight exits.
Visualisation of pedestrians on the pavement when manoeuvring out of tight parking spaces or in tight exits.
Support when travelling off-road in demanding and confusing terrain.
The colour of the GLC on the COMAND display always corresponds to the vehicle’s actual paintwork.
Relaxed driving experience
The improved ergonomics and simpler controls in the GLC compared to its predecessor also help to enhance safety. All important vehicle functions and settings can be carried out intuitively using the central rotary pushbutton or the touchpad. The desired settings or information are clearly visualised by the large, partially integrated colour media display in the middle of the dashboard. Direct selection buttons next to the light switch module to the left of the steering wheel additionally enable direct activation of the most important assistance systems.
Also new is the Head-up Display (HUD). The HUD displays important information directly in the driver’s field of vision on the front windscreen, thus providing for clear legibility and less distraction from the road ahead. The system provides information on speed, posted speed limits, navigation instructions and messages from the DISTRONIC system.
Hybrid body: the safe foundation
In keeping with the Mercedes-Benz tradition, the body forms the foundation for exemplary occupant protection in the event of a crash. A high-strength safety passenger compartment forms the core of this concept. It is surrounded by specifically designed and crash-tested deformation zones, which ensure the best possible safety for the occupants by virtue of optimised force paths and a combination of die-cast aluminium components and ultra-high-strength materials. This assures the new GLC of the potential to put in an excellent showing in all the worldwide rankings. The measures in detail:
Highly robust passenger compartment consisting of high-strength and ultra-high-strength sheet steel, tailored blanks (sheet steel with graduated wall thicknesses) and cast aluminium components
Bodyshell structure whose front and rear can absorb energy with purposeful deformations
Large deformation zone of the front due to a subframe that absorbs additional energy in an accident
Several parallel load paths for improved load distribution in partial frontal collision (offset crash)
Additional strut made of high-strength steel between the damper dome and windscreen cross-member on the driver’s side which distributes the load from forces in the upper side member plane and reduces steering and pedal intrusion in the footwell.
Additional firewall supports between the front and outer longitudinal members, which prevent the front wheel from intruding into the footwell in a severe offset frontal collision
Extruded aluminium profile cockpit cross-member between the A-pillars
Doors with reinforcement profile
Main floor with massive tunnel reinforcement and now continuous floor side members
Rear seat base with additional reinforcements, separated from the rear floor
Composite rear structure with longitudinal floor members in graduated plate thicknesses and a corresponding rear centre section
On the GLC 350 e 4MATIC with plug-in hybrid technology, a lithium-ion battery and other high-voltage components are integrated in the rear area. Special cast aluminium parts form a deformation-proof area to shield off these components.
Airbags & co.: cushioning protection for the occupants
Three-point seat belts with pyrotechnical belt tensioners and belt force limiters are installed for driver, front passenger and passengers on the outer rear seats. The centre seat of the second row is equipped with a standard 3-point belt system. A rear seat-belt status display in the instrument cluster informs the driver whether the passengers in the back have fastened their seat belts. ISOFIX child seat anchorage points on the outer rear seats ensure safe attachment of appropriate child seats with additional anchorage points at the top of the rear seat backrest. The front passenger seat can be fitted with automatic child seat recognition, which dispenses with the existing transponder and instead works with a weight mat. This enables any standard child seat to be used. The airbag is automatically deactivated in this case and reactivated once the child seat has been removed.
In addition, a host of airbags provides occupant protection in an accident. These include:
A newly developed windowbag in the area of the roof between the A-, B- and C-pillars for the head area of the driver, front passenger and passengers in the outer rear seats
Combined thorax/pelvis sidebags for driver and front passenger, which are able to provide additional protection in the event of a side impact Optional sidebags for the outer rear seats.
Kneebag for the driver to protect the knees and stabilise the upper body, which positively influences occupant movement in an accident.
Adaptive airbags for driver and front passenger with two-stage staggered deployment, depending on the detected severity of the impact and seat position.
The new GLC is equipped with Mercedes-Benz emergency call eCall. The emergency call can be made automatically or manually. It is triggered automatically after deployment of one of the pyrotechnic belt tensioners or airbags in the vehicle. The service centre then establishes voice communication with the vehicle. If there is no response, it immediately alerts the nearest rescue service.
Best possible protection for more vulnerable road users
Mercedes-Benz attaches priority to the protection of more vulnerable road users, such as pedestrians or cyclists. An active bonnet is used which is lifted by 80 millimetres in certain accident constellations, creating additional deformation space. Under the bonnet the package has been further optimised with a new engine cover and deformable air intake, creating yet more deformation space. These measures ensure that the GLC meets the markedly more stringent Phase 3 requirements of Euro NCAP pedestrian protection.
BAS PLUS warns when pedestrians are detected in the danger zone by the stereo multi-purpose camera. The PRE-SAFE® Brake with pedestrian protection triggers autonomous braking when the system detects a pedestrian in the danger zone and the driver does not react to the system’s warnings. This pedestrian detection, in conjunction with the optionally available Driver Assistance package Plus, represents a milestone in preventing accidents with pedestrians and/or reducing their consequences.
