The EA888 engine was also showcased in Audi’s TT Quattro Sport Concept with an output of 414bhp and 332lb ft.
To maximise the sledgehammer performance potential of its engine, the concept employs a six-speed manual gearbox and the latest version of Volkswagen’s Haldex multi-plate clutch 4Motion four-wheel drive system, a combination that has also been taken from the new Golf R.
The electro-mechancial 4Motion four-wheel drive system constantly alters the amount of drive sent to the front and rear axles, with up to 100 per cent of the formidable reserves able to be channelled to either end depending on prevailing levels of traction. It operates in combination with Volkswagen’s EDS and XDS+ electronic differential locks as part of the Golf R400’s multi-function ESP system, which also boasts a sport function to allow a less aggressive intervention of the electrics when the driving conditions permit.
The Golf R400 is based around the three-door Golf R, with which it shares its hot formed steel floorpan and elements of its bodyshell. Despite early rumours suggesting it may receive a wider range of weight saving measures than those featured on the concept in Beijing, it is not exceptionally light. But at 1420kg, the new Volkswagen manages to undercut the Golf R by 56kg and the A45 AMG by 135kg. This endows it with a power-to-weight ratio of 278bhp per tonne – 77bhp per tonne more than the Golf R and 50bhp per tonne more than the A45 AMG.
Volkswagen says the Golf R400 reaches 62mph from standstill in a sizzling 3.9sec, 1.0sec faster than the German car maker quotes for the Golf R and 0.7sec faster than Mercedes-Benz claims for the A45 AMG. Top speed is limited to 174mph – 19mph up on the limited 155mph maximum of the Golf R and A45 AMG, although officials suggest the gearing would allow it to crack 190mph without electronic intervention.
The powerful three-door hatchback’s styling is a lot less restrained than recent concepts based on Volkswagen’s perennial best seller in line with plans to create a car that could be considered for low volume production. Up front there is a deeper bumper sporting integral carbonfibre elements, including a prominent splitter. The cooling ducts have also been heavily modified to ram a greater amount of air into the engine bay and to the front brakes.
In a move that provides it with an even more aggressive stance than the new Golf R, the Golf R400 receives unique fenders that have been widened by 20mm, giving it an added 40mm of added width both front and rear.
Further back, there are carbonfibre exterior mirror housings and subtle sill extensions. The rear is distinguished by a carbonfibre wing spoiler atop the tailgate and a deeper bumper imbued with carbonfibre elements, vertical ducts used to extract hot air from the wheel houses as well as a carbonfibre diffuser housing two large round tail pipes.
Yellow accents are used within the headlamp assemblies, which feature the latest LED graphics, as well as the grille and brake calipers to visually set the new car apart from the Golf R, which uses chrome highlights. The new Volkswagen also sports yellow and chrome R400 badges within the grille, along the flanks and on the tailgate.
As with its driveline, the chassis of the Golf R400 is borrowed largely from the Golf R. The two share the same MacPherson strut front and multi-link rear suspension, which is set 20mm lower than regular Golf models and features DCC (Dynamic Chassis Control) that adapts the dampers to one of three modes: Comfort, Normal and Sport. A further common feature is the 19-inch wheels and 235/35 R19 tyres.
