Did you know that Volkswagen set seven 24-hour world speed records at the Nardò Ring?

Well, it did. With the Volkswagen W12 (aka. Nardo) concept.

The car produced from 420 to 600 horse power, and it was used to test the W12 engine that was, later on, used in the Phaeton and Touareg.

There was a coupe, and a roadster version of the W12 concept. It featured Volkswagen's 4x4 synchro four-wheel-drive system.
Mastermind behind the story, was, once again, dr. Ferdinand Piech.
