Car wash in Budapest. Hungary, 1970s

The A57 is a monster of an engine, and famously complex. It was created in quickly in the early years of the Second World War to alleviate some of the engine supply issues for Shermans and M3s.

This haste was possible because it used common parts already in production.

It comprised of five Chrysler straight six engines, each displacing 4.1 litres (250 cu in). A gear was fitted to the end of each straight sixes' crankshaft, all of which meshed with a central output shaft to the transmission.

All in the A57 had 30 cylinders, displaced 20.5 litres (1,250 cu in) and produced around 400 hp and 1,350 Nm (1,000 ft lb) of torque.

Its five-engine nature meant it needed five distributors, five sets of inlet and exhaust manifolds, 30 spark plugs and five carburettors. Despite the complexity, it did give its host tank added redundancy, as it could still run even with two of the five engines down.
