Each procreation of the BMW M3 has included a interchangeable model. Even the distant E30, the patriarch of the M3 short letter, had an ultra-rare (only 787 were built) droptop example. The convertible became more common without ceasing the successive generations, with the hardtop-interchangeable E93 being the most recent. Considering this narration, there seemed very little doubt that while the M3 became the M4, a interchangeable would be in the cards. Now, the renovated droptop has arrived.
Set for its global debut at the 2014 New York Auto Show, the 2015 BMW M4 Convertible features, like its forbearers, everything that’s weighty about the hardtop variant while adding some unlimited amount of head room. That property the same 3.0-liter, 425-horsepower, 406-bruise-foot, twin-turbocharged straight six sits when exposed to its domed hood, while either a six-succeed stick or a seven-speed M dual-clench transmission dispatches power to the rich rear tires.
As for specific differences betwixt the hardtop and the new interchangeable, obviously, the droptop is heavier. A chance heavier. Where an M4 with a six-make haste manual tips the scales at 3,530 pounds, the M4 Convertible weighs in at 4,055 pounds. Believe it or not, BMW has in fact trimmed 90 pounds from the last-generation M3 convertible, code-named E93. This marginal influence reduction from the third-generation convertible to the fourth is barely moiety of the 174 pounds BMW was skilful to subtract when transitioning from M3 Coupe to M4 Coupe.
While we aren’t crazy not far from 4,000-plus-pound car, BMW claims that cargo space has increased as well. Like the significance savings, though, the extra volume is negligible. There’s 13 cubic feet of watercourse space when the roof is up, an increase of 0.7 cubic feet and 7.8 cubic feet of chamber when the three-piece top is stowed. As is the tendency with convertibles nowadays, the roof have power to be lowered in 20 seconds and at speeds up to 11 miles for hour.
Sales of the 2015 BMW M4 kick done this summer. We’ll have abundant more on the latest addition to BMW’s M rank when it debuts in a small in number weeks, at the 2014 New York Auto Show. Until at that time, you can take a look at the abounding gallery of images of the M4 at the surpass of the page. You can also scope out BMW’s official urge release by scrolling down.

The New BMW M4 Convertible
Legendary acme-down motoring from BMW M
Woodcliff Lake, NJ – April 3, 2014 6:00pm EDT/3:00pm PDT. . . The aggregate-new BMW M4 Convertible arrives in US showrooms a day after the fair this summer to join the M4 Coupe and M3 Sedan. The 2015 BMW M4 Convertible is powered by the same BMW M TwinPower Turbo 3.0-liter inline-six taken in the character of its siblings. That engine produces 425 horsepower and 406 lb-ft of torque and have power to be mated to either a 6-thrive manual or 7-speed M-DCT transmittal. The new BMW M4 Convertible makes its globe debut at the 2014 New York International Auto Show.
The newly come inline-6 M engine: High-revving, turbocharged one combines the best of both worlds. Like the of recent origin BMW M3 Sedan and new BMW M4 Coupe, the repaired M4 Convertible sees a return to one inline-six engine, as used steady the second and third generations of this iconic fully prepared sports car. The new turbocharged instrument combines the best of both worlds – reaching a maximum 7,600 rpm, it is unusually haughty-revving for a turbocharged engine, resulting in in the direction of a line power delivery over a wide means speed range and a soulful weapon note, while M TwinPower Turbo technology ensures that pinnacle torque is on tap over a uncontracted rpm range. A further hallmark of this instrument is its outstanding efficiency.
The new engine sees a power upgrade from one side of to the other the previous V-8 to 425 hp, what one. is delivered between 5,500 and 7,300 rpm. Peak torque has been increased by roughly 40 percent to 406 lb-ft, and is maintained athwart a very wide rev band (1,850–5,500 rpm). The sprint from nothing to 60 mph takes the reinvigorated BMW M4 Convertible just 4.4 seconds by the 6-speed manual. Equipped by the 7-speed M Double Clutch Transmission, this contain falls to 4.2 seconds. Top accelerate is 155 mph (electronically limited). The BMW M TwinPower Turbo instrument hits maximum revs of 7,600 rpm, in keeping with the typically high-revving reputation of M engines.
The M TwinPower Turbo technology comprises two wildly-responding mono-scroll turbochargers, High Precision Direct Injection, Valvetronic fickle valve timing and Double- VANOS continuously fickle camshaft timing. Valvetronic and Double-VANOS toil in tandem to seamlessly control intake valve raise. The result is smooth and operative power delivery, very sharp response and reduced fuel consumption and emissions.
The six-cylinder agent features a closed-deck crankcase design what one. is very rigid and allows cylinder pressures to exist increased for improved power output. And instead of liners, the cylinder bores characteristic a twin-wire arc-sprayed covering, which results in a significant abasement in engine weight.
Engine weight is more distant reduced by the forged, torsionally austere crankshaft which, as well as without disrespect to weight, also provides increased torque-carrying magnitude . This significantly reduces rotating masses, resulting in improved throttle response and acceleration.
Innovative technologies delivering highest rank-level performance.
Power transfer in the BMW M4 Convertible is by way of a standard six-speed manual gearbox. Available like an option is the seven-urge Double Clutch Transmission M-DCT, that allows the driver to change gears not merely using the selector lever in the center console but also via the shift paddles forward the steering wheel. This transmission effectively combines two gearboxes, cropped land with its own clutch. This mode gear changes are executed with not at all interruption in the flow of navy – and the shift processes are thence shorter. Drivelogic allows the driver to picked from different shift modes, which escort the M4 Convertible adopting a particularly comfort-oriented, economy-focused or beyond-sporty approach to gear changes whereas in automatic mode. The Launch Control office also integrated into M-DCT enables optimum acceleration off the line.
The standard Active M Differential optimizes drawing toward at the rear axle. The electromechanical steering classification, meanwhile, represents a new development from BMW M GmbH and is the momentous component in the link between driver and car. It offers the gifts of open steering feel and precise feedback. The integrated Servotronic form electronically adjusts the level of steering patronage according to the car’s despatch, providing optimum steering characteristics at quite speeds. Three steering settings (COMFORT, SPORT and SPORT+) be possible to be selected at the touch of a button to trim the level of steering assistance to the condition at hand and to the driver’s individual tastes.
The optional Adaptive M hanging likewise comes with COMFORT, SPORT and SPORT+ modes. The BMW M4 Convertible is equipped as standard with M compound brakes, still customers can also order their car by even lighter and more effective M carbon ceramic brakes, what one. boast the additional visual highlight of gold-painted calipers.
Lightweight design over the board: Shedding weight in every part of the right places.
As well since outstanding dynamic qualities, intelligent lightweight design too allows the BMW M4 Convertible to claim excellent efficiency. Its extensive weight-saving measures produce a curb weight of just 4,055 lbs – surrounding 90 pounds less than its progenitor.
Among the key contributors here are the aluminium face fenders and hood, with lightweight aluminium mode of constructing also a feature of the chassis. Extensive appliance is also made of a matter that is both lightweight and extremely crude, and therefore durable: carbon-fiber- reinforced pliable (CFRP). The new BMW M4 Convertible in like manner features a CFRP drive shaft. The supercilious rigidity and low weight of the CFRP pipe mean that the drive shaft have power to be produced as a single-composition component, without a center bearing. This achieves system of weighing savings of 40 percent over the anterior model and a reduction in rotating masses, which in turn results in more dynamic powertrain answer.
The CFRP strut brace in the implement compartment is a further example of for what cause all weight- saving measures on these vehicles consider also been tailored to the meliorating of driving dynamics. Weighing only 3.3 lbs, the strut brace offers superior rigidity to a worthy of comparison aluminum component and at the corresponding; of like kind time plays a key part in the excellent steering response and precision of one as well as the other vehicles.
The use of carbon is a reminder that BMW is a global ruler of the roost in high-strength, lightweight CFRP building, and that it was BMW who brought out the capital mass-production vehicle with a corpse consisting entirely of this material – the innovative BMW i3.
Design: the powerfully expressive face of BMW M.
Viewed from the anterior, the BMW M4 Convertible stands out greatest in quantity prominently with its powerful contours and a firmly defined three-dimensionality, which lends it a powerfully lively face. Characteristic design elements leave nay doubt that this car is the toil of BMW M. There is the recent take on the twin headlight regulation (with optional LED technology), for exemplification, not to mention the distinctive geminate-bar kidney grille with black painted grille bars – what one. reflect the design of the characteristic BMW M double-spoke wheels and have the M logo – and the powerfully designed anterior apron with its trio of copious intakes supplying cooling air to the eminent-performance engine and brakes. Among the other hallmark BMW M design features without ceasing display is the characteristic power dome on the hood, which hints at the potential of the brawny M TwinPower Turbo means and creates space for the intercooler. And the astomshing exterior mirrors, with their suggested doubled-stalk mounts, optimize the aerodynamics of the of recent origin BMW M4 Convertible.
The flanks: humble-slung silhouette and dynamic lines.
The side view of the M4 Convertible extends the dynamic mark created by its front end. The hallmark BMW proportions of a far-reaching hood, long wheelbase, set-back glasshouse and brief front overhang are lent further significance by familiar M design elements.
Those dynamics-accentuating details include likewise newly designed M gills, which perform both a stylistic and a functional role. Integrated into them are Air Breathers, that team up with the Air Curtains in the face apron to help optimize the airflow right and left the wheel arches and therefore improve aerodynamics.
The remote design: flawless ergonomics in a sporting ambience.
Climbing into the BMW M4 Convertible, drivers determine be greeted by an interior science complete with unimpeachable ergonomics and bright driver focus. In keeping with its personal traits, however, the interior fulfils an plane more sharply defined sporting brief. To this end, the host of traditional BMW M outfit details includes M door sill finishers, each M driver’s footrest, M gearshift lever, M-design round instruments with white graphics, M leather steering wheel by chrome trim, color contrast stitching and electroplated-glance shift paddles (if the M-DCT gearbox is specified).
The van seats also represent an evocative pervasive feeling of BMW M’s motor amusement genes. Taking visual inspiration from the bucket seats fitted in racing cars, the seats mark a full- size single-piece back body of jurors. This means the construction of the seats is true flat, while the high, width-adjustable oblique bolsters and low-set seat external part allow an ideal seating position and afford excellent support. Despite their undeniably sporty design, the BMW M sports seats are equipped by comfort-enhancing features including electric reconciliation and heating. On the seat external part, the stitching, upholstery segmentation and aperture lend the seats a slim-fitting feel. Illuminated beneficial to the first time, the BMW M logo attached the seat backrests adds a unused and exclusive highlight.
Interior with delicate materials and motor sport ambience.
The BMW M4 Convertible stands out with an interior that is exclusive and functional in like measure. For example, the M Sport leather multifunction steering wheel is colors, as are bucket-style M sports seats. New to this race of Convertible are the available three-temperature neck warmers that allow for comfortable open-air driving at high speeds and reduced temperatures.
Drivers of the BMW M4 Convertible be possible to look forward to piloting their car from abaft a double-spoke M leather steering wheel. The M logo, chrome smart and color contrast stitching are central elements of the hovel’s racing ambience. The M4 Convertible comes standard with a 6-speed manual gearbox, space of time the 7-speed M Double Clutch Transmission is suitable as an option. M-DCT allows the driver to make differentin. gears using either the selector lever adhering the center console or the devise ways and means paddles mounted on the steering wheel.
Three-fire-arm retractable hardtop. Form and function.
The BMW M4 Convertible offers outstanding everyday driving qualities and a dynamic design, through the top up or down. These seemingly contradictory qualities were already combined in the BMW M3 Convertible, the precursor that set standards for premium intervening-size convertibles. The hardtop of the BMW M4 Convertible features a reckon of design improvements that reduce conversation levels for a much quieter inner part ambience. The sound-absorbing headliner in like manner reduces wind noise by up to 2 dB in simile to the predecessor model.
When the utmost degree is up, the luggage compartment has a tome of 13.0 cu. ft. (370 liters) – that is 0.7 cu. ft. (20 liters) more than available in the BMW M3 Convertible. All watercourse volumes are based on ECE measures. Even large items can be transported with the BMW M4 Convertible. A level with the ground and level storage area can have existence utilized when the backrest of the raw bench seat is folded down. The burden-through feature, which is standard in the US, makes just more space available: Either a large opening between the rear passenger section and the trunk, or a smaller chance, for skis for example, when four folks are seated in the vehicle. All it takes is the push of a button to transubstantiate a dynamic coupe into an genteel, athletic convertible in a mere 20 seconds. The upper part of a plant can also be lowered when the medium is travelling at speeds of up to 18 km/h (approx. 11 mph).
The redesigned windblock is type in the US. The windblock is at that time smaller, lighter and easier to use, plus it is more effective than prior variants. When it is not needed, the windblock be able to be stored behind the rear site to save space, which is in addition a new feature. The BMW M4 Convertible furthermore has plenty of space in the body , even when the retractable hardtop is lowered. The renovated convertible offers wider access to the traps compartment, and an electro-hydraulic loading furtherance system raises and positions the folded hardtop in the stock as needed to ensure maximum utilization of the 7.8 cu. ft. (220 liters) of storage capacity available.

The discretional Head-Up Display comes with supplemental, M-specific functions such as a gear display, rev counter and Optimum Shift Indicator.
Hall of Fame: Open-overpower performance for over a quarter centenary
The new BMW M4 Convertible builds without ceasing 26 years of tradition. A Convertible has lined up by the side of its two-door Coupe sibling since a firm fixture of the BMW M3 in the whole of four generations.
First generation: the racing car by the soft-top.
The launch of the leading BMW M3 in 1986 served originally to satisfy the homologation requirements beneficial to what was then the German Touring Car Championship (DTM). In public tranquillity to take its place on the grid because of this prestigious race series, BMW had to advance up with a series- produced rendering of the competition car and build 5,000 examples of it on account of sale within a year. The passage-spec BMW M3 was created with the demands of motor sport highly much at center stage and in that place were no plans initially for some open-top version. However, after on every side two years of resistance, BMW eventually gave in to signifying customer demand, and the BMW M3 Convertible was unveiled in 1988. It was based forward the four-seater BMW 3 Series Convertible and powered through . a four-cylinder engine initially producing 193 hp. In 1990, output was increased to 215 hp, enabling the liberalize-top M3 to accelerate to a zenith speed of 148 mph – make it the world’s fastest four-seater concatenation-produced convertible at the time. The elementary generation BMW M3 Convertible was not offered in the US.
Second procreation: new advances in safety technology.
The powers that exist in BMW’s motor sport part – now rechristened M GmbH – had planned some additional Convertible version of the advance-generation BMW M3 (launched in 1992 globally and in 1994 in the US) from the opening. Based on the second generation 3 Series Convertible, the BMW M3 Convertible was launched in 1994 with a raft of innovative safety technology adhering board. For example, the rollover bars of the banner rollover protection system – positioned following the rear seat head restraints – would wax up in an instant if the car was in peril of turning over, teaming up with the ultra-rigid windscreen frame to house the passenger compartment. In the US, the sixtieth part of a minute-generation M3 Convertible was powered initially by a 240-hp 3.0-liter inline-six that was later enlarged to 3.2-liters.
Third stock: shining an even brighter spotlight forward the car’s sporting character.
In thrive 2001, almost exactly a year succeeding the starting gun had been fired without ceasing the third generation of the BMW M3, M GmbH unveiled the Convertible variant to join its Coupe stablemate in the employment-up. It was identical to the M3 Coupe up to the A-prop, but a striking beltline gave the extended-top model an even broader, greater degree powerful appearance. The BMW M3 Convertible therefore cut a more muscular, broader, further hunkered-down figure than any BMW M3 prior to it. And it had the impose upon to back up the bark; hallmark M attributes like as a 333 hp high-revving naturally-aspirated means, beautifully tuned M suspension, a versatile M differential lock and M heaven-kissing-performance brakes enshrined the
BMW M3 Convertible while an elite athlete.
Fourth generation: giving the sporting reputation an even sharper edge.
Less than a year steady from the debut of the fourth-collection of those of nearly the same age BMW M3 Coupe and the four- entrance Sedan that followed a little later, BMW stirred the fires of expectation among open-air driving enthusiasts through the launch of the BMW M3 Convertible in hop 2008. A 4.0-liter eight-cylinder weapon generating 414 hp – and sustaining about 85 percent of its 295 lb-ft crown torque across a rev range of 6,500 rpm – gave drivers of the distil-top four-seater an impressive armoury through which to sate their appetite in quest of sporty, dynamic corner-chasing and relaxed cruising alike.
