ERA (English Racing Automobiles)
English Racing Automobiles was a British racing car manufacturer established in 1933 to produce competitive single-seater racing cars for the 1½-litre Voiturette class. Founded by Raymond Mays with Peter Berthon and Humphrey Cook, ERA combined engineering resources from British firms and racing teams to challenge continental marques at events such as Grand Prix and Mille Miglia-era meetings. ERA cars blended advanced chassis, tuned Riley-derived engines, and lightweight coachwork to secure prominence in European and British racing through the 1930s and postwar revival attempts.
History
ERA was formed in Bourne, Lincolnshire in 1933 when Raymond Mays and Humphrey Cook persuaded investors including J G Parry-Thomas associates and local businessmen to back a works team to contest the Voiturette category. Early development drew on engineering talent from Riley, MG, and Bentley Motors alumni, while design guidance came from consulting engineers associated with W. O. Bentley and Rolls-Royce circles. ERA established a workshop at Bourne and entered events at Brooklands, Donington Park, Silverstone and continental grands prix, attracting support from patrons linked to British Racing Drivers' Club and automotive suppliers tied to Lucas Industries and Smiths Group. Wartime disruption saw facilities repurposed, while postwar attempts to revive ERA intersected with projects involving BRM engineers and others from Aston Martin and Cooper Car Company.
Car Models and Technical Development
ERA's early models—designated A, B, C, D, and E—used supercharged 1.5-litre engines with cylinder heads and crankcases influenced by Riley designs and tuning by specialists from Thomas Riley & Sons networks. Chassis were ladder-type frames with lightweight aluminium coachwork by workshops linked to Woodford coachbuilders and coachmakers who had collaborated with Lagonda and SS artisans. Suspension incorporated semi-elliptic leaf springs, Houdaille-type dampers inspired by technology used by Sunbeam and Voisin in continental practice, while brakes were Drum units evolving under influence from Dunlop systems used by Bentley Motors. Later ERA Type A through R models explored new supercharger geometry, camshaft profiles tuned by engineers with connections to Napier & Son and Rolls-Royce, and experimented with de Dion rear axles used by teams such as Alfa Romeo and Mercedes-Benz.
Racing Achievements and Competition History
ERA scored major successes in Voiturette events and national grands prix, with victories and podiums at Donington Grand Prix, BRDC International Trophy, Zandvoort meetings, and European hillclimbs like Shelsley Walsh and Monte Carlo Rally-adjacent stages. Drivers in ERA cars challenged entries from Auto Union, Maserati, Bugatti, and Alfa Romeo in interwar competition, and ERAs were frequent winners in Brooklands short-distance handicap and scratch races. Postwar, ERA chassis competed in racing meetings alongside ERA Works entries run by privateers and occasionally faced newer rivals from Gordini and Cooper Car Company, with mixed results as Grand Prix regulations and technology moved toward mid-engined layouts championed later by Lotus and Cooper.
Notable Drivers and Team Personnel
Key figures included Raymond Mays as team founder and driver, mechanical contributors from the circle of Reid Railton and apprentices linked to Riley and Bentley workshops, and prominent drivers such as Dick Seaman, Peter Whitehead, Prince Bira, Reg Parnell, and Earl Howe. Mechanics and engineers who influenced ERA later joined teams like BRM, Vanwall, and Cooper Car Company, while test drivers and team managers had relationships with institutions such as the Royal Automobile Club and British Racing Drivers' Club.
Manufacturing, Facilities, and Business Structure
ERA's Bourne works combined fabrication bays, engine assembly, and dyno facilities supplied by firms associated with Lucas Industries and Dunlop. Financial backing came from private patrons including country gentry and industrialists linked to Imperial Chemical Industries-era circles and local Lincolnshire landowners who had ties to British Leyland antecedents. Production was small-batch, with hand-built chassis and outsourced coachwork from workshops that had also served Lagonda and Alvis, while engines were assembled with components sourced through networks tied to Riley and specialist suppliers used by Sunbeam and Napier & Son.
Legacy, Influence, and Preservation
ERA's designs influenced postwar British racing engineering by seeding talent and techniques that migrated to BRM, Vanwall, Cooper Car Company, and Lotus. Surviving ERA chassis are prized by collectors and featured in historic racing series organized by Historic Sports Car Club and Goodwood events, while restoration projects engage specialists from firms connected to Brooklands Museum conservators and National Motor Museum curators. ERA marque revivalists and replica builders have collaborated with engineers from Williams Grand Prix Engineering-adjacent workshops and vintage engine tuners with networks to Cosworth veterans.
Cultural Depictions and Media
ERA cars and personalities appear in period journalism of The Autocar and Motor Sport and are depicted in documentaries produced by broadcasters allied with archives like British Pathé and institutions such as the Imperial War Museums for interwar motorsport retrospectives. Photographs and film of ERA entries are held in collections curated by Brooklands Museum, National Motor Museum, and private archives associated with collectors who have lent items to exhibitions at Goodwood Festival of Speed and Beaulieu National Motor Museum.
