Rover Company
The engine, the Rolls-Royce Meteorite, was a cut-down V8 version of the V12 Rolls-Royce Meteor used in tanks, itself a terrestrial version of the Rolls-Royce Merlin and made under licence by the Rover Company. Early Antars used the petrol version made by Rover and by the early 1950s the Rolls-Royce-manufactured diesel versions of the engine.
