This Bentley motor was derived from the V8 6,230cc engine designed and manufactured by Rolls-Royce in the 1950s, which produced an “adequate” 200hp. The mid-1980s saw the same engine type expanded
to a cubic capacity of 6.7 litres, and turbo-charged. Power output increased to over 300hp, allowing the Turbo R cars to produce staggeringly high performance despite weighing more than 2 tonnes.
Later, into the early 2000s during the 50-year life of this engine design, derivatives went on to produce over 500hp.
This engine and 3-speed Rolls-Royce automatic transmission to which it is coupled were donated by Geoff Shepherd, and are on display at the Lionel Gell School of Instruction in Rowville,
