After reportedly being canned, the Golf R400, now called the Golf R420, has been spotted completely bare doing its usual runs on the Green Hell.

Previously, it was thought to receive an extremely high-tuned 2.0 litre four-cylinder (EA888) engine making 400 hp, but the new word is that an inline-five now takes over propulsion duty, possibly the same 2.5 litre turbocharged engine nicked from the Audi RS3, as suggested by the new twin oval pipes. The RS3 gets 400 hp and 480 Nm of torque, with drive channeled to all four corners through a seven-speed dual-clutch transmission. It gets from 0-100 km/h in just 4.1 seconds.

The Golf R420 spied here wears a mix of styling, starting with the front fascia of the pre-facelift R, featuring the same bi-xenon headlamps with LED DRLs and front bumper design. It sits on darkened seven-spoke alloys lifted off older Audi S models, and the tail lamps are taken off the regular Golf facelift. The rear spoiler is the same as the “standard” Golf R, unlike the hideous rear wing first seen on the R 400.

If the Golf R420 makes it to production, it will go head-to-head against the domineering Mercedes-AMG A 45, which draws 381 hp and 475 Nm of torque from a hand-built 2.0 litre M133 four-cylinder turbo. Apparently, the next-gen A 45 will push over 400 hp.
