Why it matters

The A90 Atlantic was the first all-new post-war British Austin design, and its 2.6 litre four-cylinder engine is the one later used in the Austin-Healey 100/4. Few survive; the auction listing believes about 30 are on the road in Britain.

Independent counts (e.g. engine and colour) are never combined into a calculated figure. Surviving examples are never presented as original production.

History

After the war the government pushed exports to America, and Leonard Lord wanted a sports-styled car to widen Austin's range there. He drew the basic shape himself and Dick Burzi turned it into drawings; it used A70 mechanical components and chassis. It starred on Austin's stand at the 1948 Earls Court show, as a convertible with a power-operated hood, and a hardtop followed in 1949.

To promote it in the US, an Atlantic broke 126 stock-car records at Indianapolis over seven days. Sales stayed poor, and production ended in 1952 with just under 8,000 built; its 2660 cc four lived on in the Austin-Healey 100.
