Bentley 8-Liter 1931

3D Model

The Bentley 8 Litre was a large inline 6-cylinder super-luxury car made in various configurations by Bentley Motors Limited at Cricklewood, London. Announced 15 September 1930, it was also the last completely new model by Bentley before the company’s financial collapse and forced sale to Rolls-Royce Limited. A Bentley 4 Litre featuring a 4-Litre Inline-6 engine in a shortened chassis was announced on 15 May 1931. The straight-six engine used a one-piece iron block and non-detachable cylinder head with a crankcase made from Elektron, a magnesium alloy. It featured an overhead camshaft driven by a Bentley patented “three-throw drive” system of triple connecting rods with, like all earlier Bentleys, four valves per cylinder and twin-spark ignition (coil and magneto), which were state-of-the-art at the time.The engine had a bore of 110 mm (4.3 in) and a stroke of 140 mm (5.5 in), giving a capacity of 7,983 cc (487.2 cu in).Pistons were of an aluminium alloy.
