New all-wheel-drive Ford Focus RS is powered by a 2.3-litre engine producing 345bhp and 324lb ft
Ford will chart the development journey of the new 345bhp Focus RS with a series of online films, the company has revealed.
Beginning at the end of this month, the series will chronicle the journey the new hot hatchback has taken to become showroom ready. The series will focus on the car’s design and development, testing procedures and even crash tests.
This first trailer gives a taste of what’s to come from the series.
Ford only recently revealed more vital statistics for its new, third-generation Focus RS: a 0-62mph time of 4.7sec, a top speed of 165mph and prices starting from £28,940 in the UK.
Power from the 2.3-litre four-pot Ecoboost engine is 345bhp at 5900rpm, with a redline of 6800rpm. Maximum torque of 324lb ft is delivered between 2000 and 4500rpm, but there’s an overboost function delivering up to 346lb ft for up to 15 seconds.
The Focus RS is now available to order with customer deliveries of high performance hatchback starting in Europe in early 2016.
“We promised enthusiasts a serious driving machine and, with 345bhp under the hood, that is exactly what we will deliver,” said Dave Pericak, global director, Ford Performance.
The new Ford Focus RS has been described as being on “another level” and “a really fun package” by pro racer Ken Block.
Ford Focus RS drift button and all-wheel drive
The third-generation hot hatchback received its first public at the Geneva motor show back in March, where Ford confirmed it will also come with a new ‘drift button’. The Focus RS will channel its power through a variable all-wheel drive system as part of a raft of technical innovations designed to make it the highest-performing RS model yet built.
Speaking about the RS’s so-called ‘drift’ button, Ken Block said: “It’s mainly a yaw control. There’s so many electronics on these cars these days to keep the car from doing anything fun that they’re having to put that stuff back in.”
The so-called All-Wheel-Drive with Dynamic Torque Vectoring system is by far the most significant mechanical upgrade for the RS over other Focuses, including the ST.
It is also a surprise because the early indications where that Ford had decided to stick with a two-wheel drive system for the car after trying both set-ups during development work led by Europe’s Ford Performance division. Ford claims the system provides “class-leading corner speed, limit handling and a unique drift capability”. See the new RS in action in Ford’s video, below.
The all-wheel drive system is based around twin electronically controlled clutch packs. These are located on each side of the Rear Drive Unit (or RDU, which works like a limited-slip differential).
The RDU uses sensors that monitor conditions 100 times per second to distribute power continuously between the
front and back wheels and on either side of the rear axle. Up to 100 per cent of the available torque can be sent to either wheel.
The system diverts torque to the outer rear wheel during cornering, aiding turn-in and stability. Ford says this “virtually eliminates understeer” and lateral grip in excess of 1g is possible. Ford also says the system helps to “provide neutral and adjustable limit handling and the ability to achieve controlled oversteer drifts at the track”.
Raj Nair, group vice president of global product development, confirmed that the decision to adopt four-wheel drive was taken early in the development programme, which began at the end of 2013.
“There are always debates about which way to go, but as soon as the advantages became clear it was a pretty straightforward decision,” said Nair. “The twin clutch set up offered us some real advances, not just out of corners but also on turn-in and with mid-corner stability.
“Crucially, the technology doesn’t detract from the driver experience either. This is a car you can have fun in and drift in a totally controlled way, or which you can go out and set a fast lap time in. Those two things don’t always tally, but this technology gives us the scope to do that.”
Nair also confirmed that the case for four-wheel drive was strengthened by a decision by Ford’s top management to use Performance branded vehicles as showcases for innovations on all vehicles. “You saw with the Ford GT how it will act as a halo for Ecoboost technology – we see a lot of technology that the Focus RS can highlight across the range.”
The Focus RS’s 0-62mph time makes it the fastest-accelerating RS model ever. As well as the all-wheel-drive system, the car’s accelerative prowess is aid by launch control, a first for a Ford RS model.
The driver selects launch control from the cluster menu, engages first gear, applies full throttle and then releases the clutch. The system then delivers optimum drive – including distributing torque through the all-wheel-drive system, maintaining maximum torque using the turbo overboost function, managing the traction control system, and setting the dampers.
To achieve maximum acceleration through the gears, a performance shift light in the instrument cluster alerts the driver when approaching the optimum upshift point of 5900rpm, and flashes if the engine hits its limit of 6800rpm.
The Focus RS offers four different Drive Modes that configure the all-wheel-drive system, damper controls, electronic stability control, steering and engine responses, and exhaust sound. Normal, Sport or Track settings are available, alongside the special Drift Mode.
“The all-new Focus RS delivers stunning performance and innovative technology at a price that will make both our customers and premium automakers look twice,” said Jürgen Gagstatter, chief program engineer for Focus RS. “After experiencing the acceleration and cornering capability of the Focus RS, drivers will question the sense in spending almost £10,000 more on a premium competitor.”
Speaking to Autocar, Gagstatter said that making the RS affordable was a key target of the project. “What we’ve aimed to do here is to have a technically competitive package which is affordable for our customers,” he said “that has been the overriding principal here.
“If you look back in history the previous Focus RS was front-wheel drive, but it was the right package for that time. The world moves on, and it was clear from the beginning that we needed an all-wheel drive package.
“When you start planning a replacement product [for the last Focus RS] you have a number of opinions and a number of people to talk to. Relatively quickly we found ourselves where we wanted to be in terms of performance.”
Ford Focus RS engine power and torque
The 2.3-litre four-cylinder Ecoboost engine is an uprated version of the unit available in the new Ford Mustang, producing 10% more power than that unit as a result of a variety of modifications. Changes from the Mustang engine include a low-inertia twin-scroll turbocharger with a larger compressor to aid airflow, plus a notably larger intercooler and air intake.
The Focus RS’s engine is linked to a six-speed manual gearbox that has had its shift action shortened for faster, more accurate changes. The transmission and clutch have also been uprated to cope with 324lb ft of torque, which is available from 2000rpm to 4500rpm. Additionally, 347lb ft of torque is availble for up to 15 seconds under hard acceleration, as part of a transient overboost facility.
The engine is also linked to a larger-bore exhaust system. As well as boosting performance, the system is said by Ford to be tuned to “deliver a rewarding and sporty sound character during spirited driving, with the distinctive burbles, pops and crackles that are an RS signature”.
In addition, and in the quest for high-temperature durability, the cylinder head is made of an upgraded alloy and mounted on a strengthened head gasket. For the same reason, the cylinder block also has stronger high-tensile cast iron liners. A significantly larger radiator than in the Focus ST aids cooling.
The engine’s power figure of more than 345bhp has now been ratified. However, it establishes the Focus RS Mk3 as the most powerful ‘standard’ Focus RS to date. The Mk1 Focus RS had 212bhp and the Mk2 had 301bhp. However, the special-edition Focus RS500 had 345bhp – a figure now matched by this latest RS.
Ford Focus RS set-up and pricing
The new Focus RS will be sold as a five-door model only, in line with Ford’s global strategy for the entire Focus range. Inevitably, though, the Focus RS is significantly upgraded, even from the Focus ST.
Most significantly, the chassis has been retuned, with the use of stiffer spring rates, bushes and anti-roll bars, and two-mode dampers that can be switched between road and track settings.
The electric power-assisted steering has also been retuned to work with a more rigid front suspension knuckle and shorter link arms to deliver what Ford describes as “connected and responsive steering with outstanding feel”.
To emphasise the track capabilities of the new Focus RS, it will be available with a specially developed semi-slick tyre for the first time. All buyers will have a choice of standard or lightweight forged 19in multi-spoke alloy wheels, which can be shod with either Michelin Pilot Super Sport 235/35 RD tyres or Pilot Sport Cup 2 semi-slicks. Iconic driver Ken Block has been involved in the car’s development process.
The exaggerated exterior look has been created by Ford’s stylists and the practical need for improved aerodynamic downforce and increased brake and powertrain cooling.
The interior also gets several upgrades, including Recaro sports seats, a flat-bottomed, leather-clad steering wheel, alloy pedals and a simpler dashboard layout than on standard cars. This includes a standard 8.0in colour touchscreen and Ford’s Sync2 connectivity system.
The new Focus RS – the 30th Ford to be badged ‘RS’ since the Ford 15M RS launched the high-performance series in 1968 – will enter production late this year with first sales beginning next Spring. It is expected to cost about £30,000.
Buyers will get just four choices of colours, called Nitrous Blue, Stealth Grey, Absolute Black or Frozen White. The launch car pictured here is painted in what Ford calls Liquid Blue, which is “currently only a show colour”, suggesting that it may become available as a cost option.
For the first time, the Focus RS will be sold in all global markets, including North America and China. However, most Focus RS sales are still expected to come from the traditional European markets, led by the UK. It will be built alongside the regular Focus at Ford’s Saarlouis plant in Germany.
The four-wheel drive system and other technical upgrades also raise the possibility of a final, extreme performance version of the car being sold some time around 2017, in the vein of the previous-generation Focus RS500. That car was developed in conjunction with Mountune and sold as a limited edition of 500 cars, 101 of which were sold in the UK.
Ford of Europe boss Jim Farley says the new RS “captures the essence” of the brand. “We make great cars that are affordable and that’s what defines the RS. Bringing RS back is a high point for us and customers. We don’t just want a sustainable business for Europe, we want a vibrant business. This is a part of that journey.”
Ken Block talks performance
Speaking to Autocar at the Goodwood Festival of Speed, where Block will drive the Focus RS up the famous hill climb route, racer Ken Block said he had enjoyed working on the development of the car: “It’s a fun car. It’s been fun to help with the development because all the testing and development I’ve done in the past has been on race cars.
“This car is really nice. The Focus ST is already quite nice to drive, but this is just another level. It’s a fun package.”
Prior to its dynamic debut at the Festival of Speed, Ford confirmed the hot hatchback will be powered by a turbocharged 2.3-litre engine producing 345bhp and up to 347lb ft of torque – significantly more than the 316bhp Ford confirmed when the car was initially revealed.
One of the Focus RS’s most significant upgrades is its new all-wheel drive system, something Block says he had been “pestering Ford about for years.”
“There needs to be the horsepower to go along with that, too,” said Block “They’re really hit the mark with it, the fit and finish is really nice.”
Q&A with Tyrone Johnson, Ford Focus RS engineering manager
When did Ford start work on the new Focus RS?
“We started talking about it some time ago. Certainly the engineers started thinking about it the day they signed off the last one, but of course there has to be a business case behind any decision to actually make it. Compared to making money on this kind of car, finding an extra 100bhp or so is easy. Specific approval came at the end of 2013.”
How quickly did you settle on the technical specification?
“It would have been the easiest thing in the world to add 60bhp, put bigger wheels and tyres on and bolt a wing to the back – but all of us at Ford were clear that we weren’t interested in that. We’ve been there and done that with RS; this time we wanted a different kind of RS.”
Why go for four-wheel drive?
“We actually built a four-wheel drive prototype three or four years ago, using more traditional technology. We drove it and, well, let’s say it was not satisfying to us. It didn’t have the dynamic levels that Ford has become known for and therefore we couldn’t envisage going down that route. But then this new system came on the radar, and it transformed the vehicle dynamics. We were up and running.”
How quickly did the project progress from there?
“Let’s just say it has been a busy year. Finding technical solutions was one challenge, but we were also sent back half a dozen times to try and find better solutions for less cost. We had to find better ways to achieve our goals; RS is also about being affordable, and that tension drive a lot of originality and invention.”
Was the five-door layout a hinderance?
“Of course, a three-door layout is lighter, but ultimately the five-door situation has detracted nothing from this car – nothing. It simply wasn’t an issue, and I guarantee you that this car will be amazing to drive.”
Why have road and track settings?
“We wanted this generation of Focus RS to have a greater flexibility than before. We know that RS has a purist’s heritage, and that we had to produce a proper sports car to justify that. But we also have to recognise that the world has moved on; people who bought a Focus RS Mk1 or Mk2 have families now, and we felt they might appreciate a road setting that allows them to use the car in comfort, and then to switch it for those boy racer moments.”
