The Aston Martin V8 is a grand tourer manufactured by Aston Martin in the United Kingdom from 1969 to 1989. As with all traditional Aston Martins, it was entirely handbuilt – with each car requiring 1,200 man-hours to finish.

Aston Martin were looking to replace the DB6 model and had designed a larger, more modern looking car. The engine was not ready, however, so in 1967 the company released the DBS with the straight-six Vantage engine from the DB6. Two years later, Tadek Marek's V8 was ready, and Aston released the DBS V8. With the demise of the straight-six Vantage in 1973, the DBS V8, now restyled and called simply the Aston Martin V8, became the company's mainstream car for nearly two decades. It was retired in favour of the Virage in 1989.

1970 Aston Martin DBS V8

From 1969 through 1972, Aston's flagship model was the DBS V8. Though the body and name was shared with the six-cylinder DBS, the V8 sold for much more. The body was a modern reinterpretation of the traditional Aston Martin look, with a squared-off grille and four headlights (William Towns admitted that the rear quarters were "borrowed" from the early Ford Mustang). Distinguishing features of the V8 model are the larger front air dam, 225/70VR15 tyres 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.

A road test report of the time noted that the car had gained 250 lb (113 kg) in weight with the fitting of the V8 in place of the previously used six-cylinder unit, despite the manufacturer's assurance that the engine weighed only 30 lb (14 kg) more than the older straight-six. Other contributions to the weight gain included heavier ventilated brake discs, air conditioning, fatter tyres, a new and stronger ZF gearbox as well as some extra bodywork beneath the front bumper.

Marek's V8 engine displaced 5.3 L (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 reach 100km/h (62mph) in 7.1 seconds and had a top speed of 242km/h (150 mph). 402 DBS V8s were built. A DBS V8 was planned to be used by Roger Moore's character Brett Sinclair in the television show, The Persuaders! but no V8 car was available at that time so a six-cylinder DBS was modified to look like a V8 model for use in the show.

DBS V8 by Ogle Design

The DBS V8 by Ogle Design was introduced in 1972 at the Montreal Motor Show. It is based on a DBS V8 and two cars were commissioned by the tobacco company W.O.Wills to promote their new premium brand of cigarettes: one show car with chassis number DBSV8/10380/R and one road going car with chassis number DBSV8/10381/RC. A third "replica" car was commissioned by a private party.

V8

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 six-cylinder Vantage in production.

AM V8

The V8 became known as the AM V8, a model retroactively referred to as the Series 2 V8 to separate it from later models. Visual differences included twin quartz-halogen headlights and a mesh grille, a front design which was to last until the end of production in 1989. AM V8 cars, produced from May 1972 through July 1973, used a similar engine to the DBS V8, albeit with Bosch fuel injection rather than the earlier carburetors. Just 288 Series 2 cars were built. Although David Brown had left the company, he had overseen development of this model. The first 34 cars still carried leftover "DBS V8" badging.

Series 3

The car switched back to Weber carburetors for the Series 3 in 1973, ostensibly to help the car pass new stricter emissions standards in California but most likely because Aston Martin was unable to make the Bosch fuel injection system work correctly. These cars are distinguished by a taller hood scoop to accommodate four twin-choke (two-barrel) Weber carbs. The car produced 310 hp (231 kW; 314 PS) 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; 292 PS) in 1976. The next year, a more powerful "Stage 1" engine with new camshafts and exhaust brought it up to 305 hp (227 kW; 309 PS).

These cars either fitted 225/70VR15 Avon TurboSpeed or 235/70VR15 Turbospeed Rolls Royce tyre on the Auto models or the 255/60R15 Pirelli Cinturato CN12 off the Vantage.

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. While earlier V8 cars have louvers cut into the little panel mounted beneath the rear windshield, the Series 3 and later cars instead have a small lip at the bottom of this panel, just ahead of the leading edge of the bootlid.

Series 4 ("Oscar India")

The "Oscar India" specification was introduced in October 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" three-speed automatic transmission, with wood trim fitted for the first time since the DB2/4 of the 1950s. Just 352 Oscar India models were built from 1978 through 1985. The power of the now de-smogged engines kept dropping on American market cars, down to a low of 245 hp (183 kW) in the early eighties.

The convertible "Volante" was introduced in June 1978, but featured the Series 4 bonnet from the get go - a few months before the coupé received the Oscar India update. The Volante Series 1 weighs 70 kg (155 lb) more than the coupé, due to the necessity of reinforcing the frame. At this time, manufacturing a V8 Volante took about four months from beginning to end.

US market cars received much larger bumpers beginning with the 1980 model year, adding weight and somewhat marring the car's lines. Owners of US-specified cars often modify them to have the slimmer European bumpers. By 1981, the success of the Volante meant that the coupé model was only built on individual demand. The 1980s were also tuned to provide much better fuel economy, up by some thirty percent.

Series 5

The fuel-injected Series 5 cars were introduced in January 1986 at the New York International Auto Show. The compact Weber/Marelli system no longer needed the space of the previous carburetors, so the bonnet bulge was virtually eliminated. 405 Series 5 cars were built before production ceased in 1989. The Volante Series 2 received the same changes; 216 were built.

Lagonda

Between 1974 and 1976, seven four-door Lagonda saloons were produced based on the Aston Martin V8, with a Lagonda-style outline grille fitted within the space normally filled by the standard Aston Martin grille.

James Bond

Aston Martin V8 Volante from The Living Daylights

In 1986, Timothy Dalton took over the role of James Bond from Roger Moore and EON Productions had decided to bring Aston Martin back to the Bond franchise with the new 007 now paired with a series 4 model in the film, The Living Daylights. However, the film caused some confusion for viewers (even those quite familiar with Aston Martin models of that era). At the beginning of the film, the car is a V8 Volante (convertible). The actual car used in these scenes was a V8 Volante owned by Aston Martin Lagonda chairman, Victor Gauntlett. Later, the car is seen being fitted with a hardtop ("winterised") at Q Branch. However, later scenes actually feature a pair of V8 coupés with the same number plate as the Volante seen in the beginning of the movie, retrofitted with other "optional extras" such as spiked tyres, skis, lasers, and missiles. Clearly, the car was intended to be seen as a V8 Volante with hardtop.

The V8 coupé has made a comeback in the James Bond film, No Time to Die. Aston Martin CEO Dr. Andy Palmer confirmed on June 20, 2019 that the V8 will make another appearance sporting the same registration it had in The Living Daylights 32 years prior.
