Atalanta Motors was set up at Staines, then in Middlesex, and began production in 1937. The first cars used overhead-camshaft four-cylinder engines of 1.5 and 2 litres designed by Albert Gough, with three valves and two spark plugs per cylinder, which had previously been fitted to some Frazer Nashes; a supercharged version was also available. Advanced for their time, the cars had tubular steel chassis and independent coil-spring suspension all round, with two-seat open and drophead coupé bodies by Abbott.
From 1938 Atalanta offered a 4.3-litre Lincoln-Zephyr V12, which proved the more popular choice, along with a longer four-seat version. A 1.5-litre Atalanta driven by Charles Morrison and company founder Neil Watson raced in the 1938 Le Mans 24 Hours but retired with a broken driveshaft.
The cars were very expensive, and the outbreak of war stopped production after only about 20 had been made; the company carried on making pumps as Atalanta Engineering. After the war Richard Shattock revived the name for the RGS Atalanta, sold complete or as parts kits until 1958 with Lea-Francis, Ford or Jaguar engines.
