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 levels of torque that are confirmed only as “increased” over the Mustang’s 320lb ft.
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”.
Autocar’s spy photographers, who have witnessed prototypes in action in recent months, have described the new Focus RS as sounding “very loud”.
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 316bhp is the only performance figure released to date and remains subject to ratification. 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.
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.
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 go on sale in mid-2016 and 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.
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.
