Bentley V8 Engine Factory The engine is still built at the Bentley factory in Crewe ( Cheshire, England), with each one signed off on a little plaque that sits in the engine bay. The Bentley 6.75-litre - which has been in production longer than any other V8 - is celebrating its 60th anniversary. Time to blow out some candles - preferably with the exhaust pipes of a V8. Bentley’s legendary eight-cylinder engine - the longest-serving V8 ever - has just turned 60. It first appeared in the Bentley S2, displacing 6.2 litres and developing 160bhp. Since then, it’s powered a total of 23 Bentley models, has grown to 6.75-litre and sprouted a couple of turbochargers. It’s come a long way from its origins, now pumping out 530bhp and 810lb ft of torque in the Mulsanne Speed. Figures you might describe as ‘sufficient’. null
