In 1927 Aston Martin was taken over by race driver A. C. Bertelli. He designed a 1.5-litre, SOHC engine which would eventually power the LeMans-racing Ulster. Thoughout the years the engine was devloped to include dry sump lubrication.
The Aston Martin Ulster stands as one of the most respected pre-war racecars. It was largely based on the Mark II which came before it.
The Ulster had a breif two year race program. During this time they dominated the British Tourist Trophy at Goodwood. In 1934, Ulsters took first, second and third place. The best LeMans result was achieved in 1935. Chassis LM20 raced to third overall which put it first in the 1101 to 1500cc class.
After the race efforts, Aston Martin readied a production version of the LeMans cars. Twenty-One of these cars were built of which all are accounted for today.
