2-seater, tourer, coupé, saloon, fabric saloon, limousine, landaulette, Coupé de Ville.

Bigger, 51bhp version of 520's engine, but still cable-operated brakes, though mechanical fuel pumps, hydraulic dampers and chromium plating standard by '30. Seven-seater bodies (including tourers) on 1231/2ins wheelbase. Artillery, disc or wire wheels though the latter seldom seen before mid-1930s. Not as American-looking as a 522.
