Why it matters

A 1999 concept in which the newly Volkswagen-owned Bentley showed a mid-engined W16 supercar. It anticipated the Bugatti Veyron, whose production car took over its engine layout and interior ideas, and marks the moment when the group decided to give the hypercar role to Bugatti rather than Bentley.

History

The Hunaudieres was unveiled at the 1999 Geneva Motor Show, named after the Hunaudieres straight at Le Mans. It used an 8.0-litre W16 engine, described by one source as two V8s joined together, with all-wheel drive, and was reportedly built on a modified Lamborghini Diablo chassis with extra headroom and a leather and nubuck interior.

Volkswagen predicted sales of about 300 cars a year at roughly 250,000 pounds, but soon decided Bentley should stay with saloons and coupes. The W16 idea went to Bugatti, and the concept remained a one-off. Bentley told one outlet that its archive held no original press material on the car.
