Volkswagen W12

It started out in 1997 as a concept car to showcase the new W12 engine. It wasn't expected to be put into production but Volkswagen now plans to produce both a coupe and convertible version. Around 300 will be produced in the first year. For any doubters, the W12 broke record after record during a high speed testing averaging almost 182 MPH for 5,000 miles straight to break the previous record of 173 held by the Corvette LTS.
