VW Golf R 400 Concept gets official at the Auto China 2014

Article by Andrew Christian, on April 19, 2014

Earlier this week we revealed you the first sketches, but today the all-new VW Golf R 400 Concept made its official debut at the Auto China show in Beijing. The new concept car is based on the flagship Golf R hatchback and was developed by the Volkswagen R GmbH. Just like the Golf R, it is powered by the 2.0-litre four-cylinder turbocharged engine (Type EA888), boosted from 300 to 400 hp and an impressive 450 Nm of torque available from 2,400 to 6,000 rpm.

Bolted to a six-speed DSG dual-clutch automatic transmission, the engine delivers the power to the four-wheel drive system and can push the vehicle from 0 to 100 km/h (62 mph) in 3.9 seconds while the top speed is 174 mph or 280 km/h.

In order to achieve that power increase, Volkswagen added a new turbocharger with a higher maximum charge pressure and reinforced crankcase and a water-cooled exhaust gas feed to the turbocharger that reduces full-load fuel consumption.

With a total weight of 1,420 kg, the Golf R 400 Concept has the same weight as the standard Golf R, despite the power increase. Moreover, the concept is 20 mm wider than the standard Golf R, as it features flared wheelarches inspired by those on the 1988 Rallye Golf G60.

The wheelarches are painted in Silver Flake metallic and are in contrast with the gloss black roof and carbon door mirror caps. New sill extensions seamlessly bridge the gap between the widened arches. Under the wheelarches we find 19-inch alloy wheels, a development of the Cadiz wheels found on the Golf R.

The new wheels feature high-gloss back inserts that act as air vanes, helping to cool the reinforced braking system and are wrapped in 235/35 R19 tires. The front end of the vehicle features a new front bumper fitted with a carbon fiber splitter and an aerodynamic wing element. Moreover, we see the ‘R’ badge on the gloss black radiator grille sits a ‘Lemon Yellow’ background.

At the rear we find a black double spoiler with LED brake lights, a redesigned bumper includes new side vents and two centrally mounted tailpipes that replace the four standard tailpipes found on the Golf R. Inside, there are motorsport shell seats with integrated head restraints and belt openings.

The seats are upholstered in cross-quilted panels covered in Alcantara and ‘carbon leather’. Stitching throughout the interior is in contrasting ‘Lemon Yellow’. [source: Volkswagen]

Press Release

VW Golf R 400 Concept

The latest Golf R production model was introduced with 221 kW / 300 PS of power and all-wheel drive. It handles the sprint to 100 km/h in 4.9 seconds and attains a top speed of 250 km/h (governed) - this is the sharpest production Golf ever and one of the most agile sports cars in its class. But the potential of the Golf - which made its debut exactly 40 years ago and developed into one of the world's most successful cars - enables even further extensions to the limits of what is feasible in sporty performance. Volkswagen is demonstrating at Auto China 2014 just how far these limits can (currently) be extended in the world premiere of the Golf R 400 concept car. Its name reflects its mission. It is a Golf developed by Volkswagen R GmbH - the brand's sports car manufacturer. 400 stands for 400 PS (294 kW). The powerful engine with the genes of the WRC racing version propels the Golf to 100 km/h in 3.9 seconds. Its top speed, assuming that a German motorway or race course is available: 280 km/h (governed).

3.55 kg per PS

The Golf R 400, including its all-wheel drive system, weighs just 1,420 kg thanks to its compact high-performance engine (2.0 TSI), lightweight dual-clutch gearbox and low body weight. Its weight-to-power ratio is a dominant 3.55 kg per PS. The permanent all-wheel drive system by Volkswagen - 4MOTION - is also one of the most fuel-efficient systems of its kind. In addition, the Golf is also exceptionally aerodynamic, as the R 400 as well. Perfection in details runs through the entire concept of the Golf R 400 - from the engine to the largely new body design. This extreme Golf is painted in "Silver Flake"; creating a contrast to this light metallic colour are the car's glossy "Black" roof and mirror caps in genuine carbon. Also designed in painted carbon effect are the splitters (wrap-around aerodynamic parts) adapted from motorsport and genuine carbon accents in the interior.

R 400 turbocharged engine

The Golf R 400 is powered by a 2.0 TSI with the technical genes of the WRC racing engine. Compared to the 221 kW / 300 PS Golf R, the Golf R 400 develops 100 PS more power, thus providing 295 kW / 400 PS (at 7,200 rpm) - which is 200 PS per litre of engine displacement. This specific power figure lies on the same level as that of super sports cars. The engine's maximum torque was increased by 70 Newton metres to 450 Newton metres (between 2,400 and 6,000 rpm).

R400 all-wheel drive system and running gear

Typical of all Golf R cars, due to their exceptional power reserves, has always been their permanent 4MOTION all-wheel drive system. Of course, this also applies to the Golf R 400 being shown in Beijing. In this car, the all-wheel drive system is coupled with an automatic 6-speed dual-clutch gearbox (DSG), which can also be shifted manually as an alternative via the gear shift lever or steering wheel paddles.

Clever control

The 4MOTION all-wheel drive of the Golf R, which has been perfected with such features as a Haldex-5 coupling, is activated even before slip occurs. Traction loss is practically prevented by this. The system makes use of a pre-control strategy here, which depends on the specific driving state. Under low load conditions, or during coastdown, the front wheels transfer most of the propulsive power, while the rear axle is decoupled. This basic tuning saves on fuel. If necessary, the rear axle of the Golf R can be variably engaged in fractions of a second as soon as this becomes necessary. This is done by means of the Haldex coupling that is activated by an electro-hydraulic oil pump.

EDS, XDS, ESC Sport

Along with the Haldex coupling, which acts as a central differential lock, the electronic differential locks (EDS) integrated in the Electronic Stability Control (ESC) system act as transverse differential locks. In addition, the Golf R 400 is equipped with the XDS+ system on both the front and rear axles, which brakes the wheels at the inside of a bend during fast driving through bends, and which optimises steering response as a transverse differential lock. Last but not least, the Golf R 400 has an "ESC Sport" function like that of the production model. The system is activated via a two-stage switch on the centre console. When the driver presses the button once briefly, this selects the "ESC Sport" mode of Electronic Stability Control (ESC). During very fast driving with lots of bends - e.g. on a race course - the ESC does not intervene as frequently, which enables even more agile handling properties. If the ESC button is held down more than three seconds, the system is fully deactivated for professional drivers on a race course.

Sport suspension and new wheels

The sport suspension of the production Golf R, which lowers the ride height by 20 mm compared to the base Golf, did not have to be changed for the Golf R 400 thanks to its large power reserve. In front, the two Golf R versions each have a MacPherson-type suspension with lower wishbones, while what is known as the modular performance suspension (multi-link suspension) is used at the rear. The tyres are also the same on both cars: 235/35 R 19. The alloy wheels of the Golf R 400 are a new development. Their design is based on the 19-inch "Cadiz" production wheels, but they were highly modified and equipped with high-gloss black inserts which, as air vanes, perfect cooling in the reinforced brake system.

Side profile

Volkswagen Design made wide-ranging design changes to the Golf R 400. For one, the body was widened by 20 mm on each side to accommodate the 19-inch wheels that are further outboard due to their larger wheel offset. In front, the designers developed an entirely new wing, which - as a modern interpretation of the legendary Rallye Golf G60 (from 1988) - are significantly flared. Similarly, the rear side panels over the wheel housings of the Golf R 400 were also flared. The wheel arches are painted in body colour as a uniform part of the new wings and side panels. In addition, the bottoms of the sides are characterised by a wrap-around splitter made of visual carbon that is a very flat aerodynamic element derived from motorsport. Perfection in the details: the fibres of the visual carbon parts in the exterior area that just have a matt coating are aligned in the driving direction, and as arrow-shaped elements they emphasise the dynamism of the R 400. Above the splitter, designers also adapted the side sills to the new contours, creating a uniform transition to the newly designed wheel arches.

Front end

Designers have redesigned the front end of the Golf R 400 as well. Beneath the high-gloss black radiator grille with its "R badge", on a background in "Lemon Yellow", the Golf R 400 also features a line in "Lemon Yellow". Similar to the line of the Golf R (chrome line), Golf GTI (red line) and the new Golf GTE (blue line), it forms the termination of the grille towards the rear and continues into the headlights on the left and right. Beneath this line, there is a type of slot that serves as an air inlet on the Golf R 400 to help cover the car's elevated cooling requirements. The bumper was also completely redesigned. The central air inlets have a surround that is a wing-like element made of carbon effect, which visually appear to hover in the bumper. The lines of this aerodynamic element run horizontally up to the height of the bi-xenon headlights, then they bend in a V-shape towards the rear, and finally describe the form of a C (left) and a reversed C (right). Self-contained wing elements in high-gloss black also hover in the lower air inlets. Between the aerodynamic element of visual carbon and the high-gloss black wings (as well as within these black elements) there is a protective screen whose honeycomb structure - like so many details of the Golf R 400 - is reminiscent of motorsport vehicles. Since the wing element protrudes somewhat further forward, this gives it a progressive three-dimensional appearance. As in the side profile, there is also a motorsport-derived splitter in carbon effect at the front.

Rear section

At the rear, the wrap-around motorsport splitters transition into a diffuser, which - like the front wing element - protrudes slightly out from the body. Integrated here are the two central exhaust tailpipes. The reason: in contrast to the Golf R with its four tailpipes (two each, left and right), the Golf R 400 follows the design of the Golf R32 - the original R-series model presented in 2002. Specifically, there are two polished tailpipes with a diameter of 110 mm, which are spaced 200 mm apart from one another and extend slightly upwards. Perfection in the details: the exhaust tailpipes have an inner part that is visible from the outside, which repeats the honeycomb design of the front air inlet. The designers also redesigned the rear bumper; at each end of the bumper there is a carbon inlay in a C-shape (reversed C on the right). The reflector is integrated in the lower horizontal part of the C; the vertical part protrudes slightly from the bumper. Here the designers have worked in a wheel arch exhaust vent.

Dual rear spoiler design

The black roof transitions into a roof spoiler that is also in black. It has two levels: viewed from the rear, the gaze is directed through the two "flying" spoilers, one above the other, to the roof. Designers have integrated an LED brake light bar in the rear spoiler.

R 400 interior

The interior of the Golf R 400 has also been extensively customised. The driver and front passenger have motorsport shell seats with integrated head restraints and belt openings. The cross-quilted middle seat panels are designed in Alcantara ("Anthracite" colour); the areas at head level and the inner surfaces of the lateral supports are designed in exclusive "carbon leather". The same applies to the outer side of the shell seats. The decorative stitching and stitch tucks (contrasting seams on lateral supports) create a contrast to the fresh "Lemon Yellow" colour. "R" badges are embroidered in the leather on the backs of the front seats. The rear individual seats are also designed in "carbon leather" on their outer areas, and the inner surfaces are upholstered in Alcantara. The area between the two seats is trimmed in black "Nappa leather".

Carbon accents

Carbon is also the dominant material for accents in the doors and on the passenger's side of the dashboard - in contrast to the exterior, however, it is coated here in a glossy rather than matt clearcoat. The centre console accents, cockpit surround and trim around the air nozzles are designed in glossy black piano finish. Carbon leather is used for the door inserts. The door armrests, meanwhile, have contrasting stitching in "Lemon Yellow". There is white ambience lighting around the door accents and the stainless steel door sill plates. Carbon leather is used in the "R" design of the three-spoke sport leather steering wheel. All leather elements are also customised by decorative stitching in the contrasting colour "Lemon Yellow" - perfection down to the smallest of details.
