The Bentley Hunaudières is a concept car built by Bentley for the 1999 Geneva Salon International de l'Auto. It is powered by a Volkswagen 8.0-litre, naturally aspirated, W16 engine adapted and modified by Bentley to generate 623 brake horsepower (465 kW; 632 PS) of power at 6,000 revolutions per minute and 760 newton metres (560 lb·ft) of torque at 4,000 revolutions per minute in conjunction with a five-speed manual transmission. It is capable of a 350 kilometres per hour (220 mph) top speed.
The Hunaudières' name pays homage to the famous straight of Circuit de la Sarthe where Sir Tim Birkin in a "Blower Bentley" overtook Rudolf Caracciola in a Mercedes-Benz SSK at 125 miles per hour (201 km/h) with one wheel on the grass down the Hunaudières straight.
The concept, along with the similar Audi Rosemeyer, led to the production of the Bugatti Veyron by parent Volkswagen.
The Bentley Hunaudieres was featured in 2000 video game TOCA World Touring Cars as an unlockable car.
