But luckily someone did. Inevitably the GTI W12 is a one-off creation, built to show at the Woerthersee VW/Audi modified car gathering in Austria.
Not surprisingly, the GTI W12-650 has a fair amount of power from its twin-turbocharged W12; 641bhp, to be precise, or 650PS (hence the name). It also packs 553lb ft of torque.
VW reckons it will run from 0-62mph in 3.7sec, and head on to 202mph, which is pretty much on a par with a Porsche 911 Turbo.
The engine is mounted longitudinally behind the front seats, and powers the rear axle through a DSG gearbox. The wheels are based on the GTI’s standard items, but at 19in they are larger and the tyres much wider – 235mm up front and 295mm at the back.
