From 1969 through 1972, the DBS V8 was Aston's top car. Distinguishing features of the V8 model are the larger front air dam and lack of wire wheels, though some six-cylinder DBS cars also used the V8's alloy wheels. The tail lights were taken from the Hillman Hunter.
Marek's V8 engine displaced 5.3 Ltr (5,340 cc/325 in³) and used Bosch fuel injection. Output was not officially released, but estimates center around 315 hp (235 kW). The DBS V8 could hit 60 mph (97 km/h) in 5.9 seconds and had a top speed of nearly 160 mph (257 km/h). A DBS V8 was to be used by Roger Moore in the television show, The Persuaders!. However, no V8 car was ready, so a six-cylinder DBS was modified to look like a V8 for use in the show.
In April, 1972, the DBS V8 became just the Aston Martin V8 as the six-cylinder DBS was dropped, leaving just this car and the Vantage in production. Although David Brown had left the company, he had overseen development of this model.
The V8 became known as the Series 2. Visual differences included twin quartz headlights and a mesh grille. Series 2 cars, produced from 1972 through July 1973, used a similar engine to the DBS V8. Just 288 Series 2 cars were built.
The car switched back to carburettors for Series 3 in 1973. These cars are distinguished by a taller hood scoop to accommodate four twin-choke Weber carbs. The car produced 310 hp (231 kW) and could reach 60 mph (97 km/h) in 6.1 seconds with an automatic transmission or 5.7 with a manual. Performance suffered with emissions regulations, falling to 288 hp (215 kW) in 1976.
The next year, a more powerful "Stage 1" engine with new camshafts and exhaust brought it back up to 304 hp (227 kW). Production of Series 3 cars lasted from 1973 through October 1978, but was halted for all of 1975 -967 examples were produced in this time.
The "Oscar India" specification was introduced in October of 1978 at the Birmingham International Motor Show. Visually, the former scoop on the bonnet gave way to a closed "power bulge", while a spoiler was integrated into the tail. Most Oscar India cars were equipped with a Chrysler "Torqueflite" 3-speed automatic transmission, with wood trim fitted for the first time since the DB2/4 of the 1950s. Just 291 Oscar India models were built from 1978 through 1985.
The fuel injected Series 5 cars were introduced in 1986 at the New York International Auto Show. The compact Weber/Marelli system no longer needed the space of the previous carburettors, so the bonnet bulge was virtually eliminated. Only 61 Series 5 cars were built before production ceased in 1989.
