The Crewe built Rolls-Royce – Bentley L Series V8 engine was introduced 1959 and is still in production. It was used on most Rolls-Royce and Bentley motor cars in the four decades after its introduction and today it is used in Bentley Mulsanne. With BMW's acquisition of the rights to use the Rolls Royce name in 1998, Rolls-Royce Motor Cars began using BMW supplied V12 engines but Bentley Motors Limited under Volkswagen ownership continued to use highly modified versions of the L Series on its Bentley Arnage, Bentley Brooklands and Bentley Mulsanne models, with VAG W-12 engines being used in its Bentley Flying Spur and Bentley Continental models. ==History== United States firm Marmon developed the first engine of V8 configuration in 1904, though it was experimental and did not find its way into a passenger vehicle. Rolls-Royce premiered the world's second V8 engine in 1905 for their eponymous Rolls-Royce V-8. Production of this engine predated by a decade Cadillac's first mass production of a V8 engined automobile. The 1905 Rolls-Royce V8 was not a success, with only three made and just one sold, which was soon returned to the factory to be scrapped.〔Ludvigsen, Karl. "Bentley's Great Eight", Dalton Watson Fine Books, ISBN 978-1-85443-241-4〕 Rolls-Royce acquired Bentley in 1931 and continued to use Bentley engines alongside their own for a time, although none was a V8. Prior to World War 2, Rolls-Royce had developed a 7.3 litre V-12 for the Phantom III, which was succeeded by the inlet-over-exhaust B60 straight-6 and B80 straight-8 series of engines. The B80 powered the Phantom IV limousine, whilst the 4.3 litre B60 was used until 1955 to power the Rolls-Royce Silver Wraith and Silver Dawn and the Bentley Mark VI. The B60's bore was enlarged in 1955, increasing the displacement to 4.9 litres, that engine being known as the B61. The need for a new engine was recognised by Rolls Royce in the early 1950s and its development began in 1952, bearing no relation to the 1905 Rolls-Royce V8. The result was a series of V8 engines known as the L series, more specifically the "L410" for its bore size of , in keeping with company practice. Developments of the L410 continued in production powering Rolls-Royces up to 1998 and Bentleys into the 21st century. Bentley, under Volkswagen ownership since 1998, continues to develop the L410 for its range of cars. Roll-Royce ceased using the L410 with the switch to BMW ownership of that brand in March 1998 and introduction of a BMW sourced V12 engine in the Rolls Royce Silver Seraph. Since 1998 therefore, development and use of the L410 engine can be said to have been exclusively a Bentley enterprise. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Rolls-Royce – Bentley L Series V8 engine」の詳細全文を読む スポンサード リンク
