DBS V8

The DBS V8, a full four-seat grand touring car capable of well over 150 mph, was announced on 27th September, 1969. The production engine had a stroke of 85 mm and a bore of 100 mm, which gave a capacity of 5,340 cc. The compression ratio was 9.00:1 with Bosch fuel injection fitted as standard. Power output was not quoted, although Motor estimated it to be 375 bhp; Gershon (Aston Martin 1963-1972), records 345 bhp as the original specification. Initially, the output was 310-320 bhp at 5,000 rpm, but Michael Bowler (Aston Martin V8), also made it clear that the production engines were producing less than 300 bhp in 1971. Engines that met the U.S. emission control regulations had a reduced compression ration delivering a further reduction in power. The body was a mildly modified DBS, to coincide with the introduction of the DBS V8, as was the basic specification of the chassis. Important differences, however, included the use of alloy wheels for the first time on a production Aston Martin, Girling ventilated discs, increased spring rates power steering as standard and Chrysler Torqueflite three-speed transmission offered as an alternative to the ZF five-speed gearbox with slightly different ratios to those of the DBS.
