 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.

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 F-head 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 4.1 inches (104.1 mm), 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.

L Series Engine Nomenclature

The factory nomenclature for the L Series V8 engines, in chronological order, is as follows:
  • L380 1950s 5,204cc initial development version
  • L410 1959 6,230cc production version powering Phantom and S Series
  • L425 1965 7,439cc experimental version
  • L410B 1965 6,230cc updated production version powering Silver Shadow and T Series
  • L410 1970 6,750cc production version, capacity increase achieved by 'stroking' to 3.9 inches (99.1 mm)
  • L410E 1970s 7,269cc development version with 4.2 inches (106.7 mm) stroke
  • L380 1970s 5,352cc “Thermodynamically Optimised Porsche (TOP)” experimental version
  • L410D 1982 6,750cc turbocharged production version installed in Bentley Mulsanne
  • L410I 1986 6,750cc fuel injected version
  • L410IT 1987 6,750cc fuel injected production version of Bentley Mulsanne Turbo R
  • L675 1998 6,750cc development name for Arnage version of the turbo, later reverted to “L410”
  • L410TT 2007 6,750cc production version introducing twin MHI turbochargers with intercooler
  • L410HT 2009 6,750cc variable cam phasing “high-torque” production version for 2009 Mulsanne
