The one-off Napier-Bentley was built in 1968 by David Llewellyn, initially on a Sunbeam chassis. But following a serious accident, the car had to be rebuilt, and a chassis from a 1929 8-litre Bentley was chosen as the new framework. The addition of the 24-litre Napier engine, a powerful combination of an aircraft engine with a marine crankshaft, meant the new incarnation was capable of generating an incredible 550bhp.
