The high-performance DB5 Vantage was introduced in 1964 featuring three Weber twin-choke 45DCOE side-draft carburettors and revised camshaft profiles, delivering greater top-end performance at the expense of overall flexibility, especially as legendary Webers are renowned as 'full-throttle' devices. This engine produced 315 hp (235 kW). Only 65 DB5 Vantage coupés were built.
Just 123 convertible DB5s were produced (also with bodies by Touring), though they did not use the typical "Volante" name until 1965. The convertible model was offered from 1963 through to 1965. Originally only 19 of the 123 DB5 Convertibles made were left-hand drive. 12 cars were originally fitted with a factory Vantage engine, and at least one further convertible was subsequently factory fitted with a DB6 specification Vantage engine. A rare factory option (actually fitted by Works Service prior to customer delivery) was a steel removable hard top.
From October 1965 to October 1966, Aston Martin used the last 37 of the Aston Martin DB5 chassis' to make another convertible model. These 37 cars were known as "Short Chassis" Volantes and were the first Aston Martins to hold the "Volante" name. Although calling it a "Short Chassis" is a bit of a misnomer as the "short" comes from comparing it to the subsequent DB6, which has a longer chassis. When compared to the DB5, it is not "short" but rather the same size, however these cars differ to the DB5 convertible models as they feature DB6 split front and rear bumpers and rear TR4 lights, as also used on the DB6.
