Sketches of the mega-hatch have been released ahead of its debut later this month at the 2014 Beijing motor show, where it will present with a supercar-rivalling acceleration time of 3.9 seconds.
That shaves 1.1 seconds off just-released Volkswagen Golf R on which it’s based, with tuning taking the 2.0-litre four-cylinder turbo’s outputs from 206kW to 295kW and 380Nm to 450Nm.
Power is put to the ground via a six-speed dual-clutch gearbox and Haldex all-wheel-drive system.
The Golf R 400 concept drawings, however, depict a more dramatic-looking hatch, with just three doors, aggressive bumpers and a low-slung look. The R 400 is said to be 40mm wider than the regular R, while 19-inch wheels fill flared wheel arches that VW reportedly says are inspired by the Rallye Golf G60 of 1988.
