The Napier Bentley is a vintage racing car; a one-off special built in 1968 by David Llewellyn. It was built on a Sunbeam chassis, but after a serious accident was re-built on the chassis of a 1929 8 Litre Bentley. It has a 24 Litre Napier Sea Lion W12 boat engine based on the Napier Lion aeroplane engine (the same as that used in the silver Napier-Railton, which it resembles closely), which develops approximately 550 bhp (410 kW). It is seen at historic racing events mostly in the United Kingdom, but has been used at European events.
With its red bodywork and Napier-Railton-esque grille, it is spectacular and entertaining in action. Being a W12, the engine has three banks of four very large stub exhausts, one of which points straight out the side of the car. The sound of the car has been likened to a World War I biplane or cluster or mortar bombs going off. Due to the immense torque of the engine (c.1400 ftlbs), the rear tyres can be made to produce clouds of smoke whenever the car is launched, while the exhausts produce sparks, flames, and smoke.
Since 1999, the car has been owned by Chris Williams, who later constructed another similar special, the Packard-Bentley.
