Over the weekend Volkswagen quietly released some new photos of three Golf GTI concepts to help celebrate the model’s 50th anniversary.

Golf GTI W12-650

The wildest of the three concepts, at least in this writer’s opinion, is the W12-650 which made its debut at the 2007 GTI Festival in Wörthersee, Austria.

Based on the three-door Mk V GTI, the W12-650, as its name suggests, is powered by a 6.0-litre twin-turbo W12 engine borrowed from the Bentley Continental.

Intakes on the roof and sides help to feed air into the W12 engine, which lives where the rear seats normally reside. It pumps out 478kW (or 650 metric horsepower) and 720Nm to the rear wheels via a six-speed automatic from the Volkswagen Phaeton.

Flat out, it can obliterate the 0-100km/h standard in 3.7 seconds, and hit a claimed top speed of 325km/h.

Other elements pilfered from the Volkswagen Group parts bin include front brakes from the Audi RS4, and a rear axle from the Lamborghini Gallardo.
