1957→1959 Aston Martin DB MkIII Drophead Coupé

In 1959, Aston Martin lauched the ultimate version of the DB2 known as the MkIII. It was the first prodcution car to use the new refined grill shape that would come to define the face of Aston Martin.

Not limited to styling upgrades the engine was reworked by Tadek Marek to produce 178 bhp which was 16 more than its DB2/4 predecessor. Furthermore the brakes were upgraded to include front discs with rear aluminum alfoin drums.

In 1958, Aston quietly announced a new DBB-specification engine with triple Weber carburetors, higher-compression pistons and a new exhaust which raised horsepower to 195 bhp. This was only ordered on 10 of the 511 Mark III cars produced.
