This amazing assemblage is the V12 Rotorvic two stroke which appeared in British club racing in 1965, powering a specially modified Lotus 23 sports car. It consists of six Ariel Arrow two stroke motorcycle engines disposed at an included angle of 90-degrees and driving the central shaft. Transmission was via a Hewland five-speed gearbox and the engine was cooled via huge air-scoops in the body panelling. This 1482cc V12 made a ferocious noise and it was almost impossible to tell it was misfiring on one or two cylinders. It produced 220bhp at 10000RPM. The creator was R.V. Marchant and the driver was Bill Hill.
