The ERA was produced by Raymond Mays, Humphrey Cook and Peter Berthon as a challenger in the 1500cc racing class. The ERA used a conventional chassis, a 4-speed pre-selector gearbox and a highly-developed version of the blown 6-cylinder ohv Riley engine giving 165bhp. There were 1100cc and 2-litre power units as alternatives, and with the D-series Porsche trailing-arm independent front suspension was introduced. Only 16 ERA cars were made, but the ERA car dominated the voiturette class in the hands of such drivers as Mays, B. Bira, Seaman, Fairfield, Arthur Dobson and Earl Howe. Victories outside Britain included the Eifelrenne, the Coppa Acerbo, Berne and Masaryk in 1935; the Prince Rainier Cup and Albi in 1936; the Avus, Picardie, Albi and Berne in 1937; and Picardie again in 1938. The ERA cars also dominated British road racing in their day and Raymond Mays achieved numerous fastest times at Shelsley Walsh with his ERA 2-litre car. Fifteen ERA cars still survive and are prominent in ‘historic’ racing. A sports-car project in 1937 came to nothing, but a new ERA 240bhp short-stroke six, the E-type with torsion-bar independent front suspension, a De Dion rear axle, synchromesh gearbox and streamlined body, appeared in 1939.

After World War 2 Mays and Berthon worked on the BRM V16, while ERA, now under the control of Leslie Johnson, struggled on with the unsuccessful ERA E-types until 1949. The company assisted in the design of Jowett’s 1950 ‘Jupiter’ sports car, but their last racing machine, the ERA G-type, was designed for Formula 2, and had a 150bhp 6-cylinder Bristol engine and tubular frame to the designs of David Hodkin. This final ERA product was sold to Bristol’s for testing.
