Background
Launched in 1969, the Aston Martin DBS V8 was built upon the DBS platform, with a 5.3-litre V8 engine - designed by Tadek Marek - upfront, replacing the standard DBS’ straight-six engine, which in itself had been lifted from the Vantage of the period.
With the option of a five-speed all-synchromesh manual gearbox or a three-speed automatic transmission sourced from Chrysler, the DBS V8 was every inch the thoroughbred British muscle car, giving the perfect physical form to the phrase ‘an iron fist in a velvet glove’ thanks to its sheer power encased in a typically upmarket, hand-built Aston Martin body.
From 1972, the straight-six DBS was dropped from the lineup, and the DBS V8 was subsequently referred to as the AMV8, also known as the ‘Series 2 V8’ with numerous visual differences such as a redesigned front end with twin (rather than quad) lights, a mesh grille and Bosch fuel injection.
In 1973, the Series 3 cars were introduced, which saw the unusual implementation of Weber carburettors in place of the Bosch fuel-injection system seen in the S2 V8s, allegedly to help pass CA emissions laws, but more likely due to the fuel injection system never quite being perfected by AM. Distinguishable by their pronounced hood scoop to feed the carburettors, the S3 AMV8 was capable of a 6.1-second 0-60 sprint with an automatic transmission (5.7 with a manual) and 310bhp, which subsequently dropped to 288hp in 1976 due to emissions regulations.
From 1977, however, a ‘stage 1’ engine was available, featuring new camshafts, a modified exhaust system, and a raised power output of 305bhp.
In the end, production of S3 AMV8s was carried out between 1973 and October 1978, though no cars were produced during 1975, and a total of only 967 were built, with each car taking around 1,200 man-hours to produce.
