The first series equipped with four 48IDF2/100 Weber carburetors produced 390 bhp (395 PS; 291 kW) (estimated) at 5800 rpm and 406 lb⋅ft (550 N⋅m) at 4500 rpm of torque, and series specific details such as a blanked bonnet vent and a separate rear spoiler.
38 of these were built (plus 13 "Cosmetics" for the US).
The Oscar India (for 1 October, the date of introduction) version, introduced in late 1978, featured an integrated tea-tray spoiler and smoother bonnet bulge.
Inside, a black leather-covered dash replaced the previous walnut.
The wooden dashboard did find its way back into the Vantage during the eighties, giving a more luxurious appearance.
The Oscar India version also received a slight increase in power, to 390 bhp (291 kW).
This line was produced, with some running changes, until 1989.
From 1986 the engine had 403 bhp (301 kW).

One of the most noticeable features was the closed-off hood bulge rather than the open scoop found on the normal V8.
The grille area was also closed off, with twin driving lights inserted and a spoiler added to the bootlid.

The 1986–1989 580 'X-Pack' was a further upgrade, with Cosworth pistons and Nimrod racing-type heads producing 403 hp.
 A 'big bore' after-market option was also available from Works Service, with 50 mm carbs (instead of 48 mm) and straight-through exhaust system giving 432 hp (the same engine as fitted to the limited-edition V8 Zagato.
16-inch wheels were also now fitted.
If this wasn't enough, a 450 hp (336 kW) 6.3-litre version was also available from Aston Martin, and independents offered a 7-litre version.

304 Series 2 Vantage coupés were built - including 131 X-Packs - and 192 Volantes (in spite of only having been officially introduced in 1986, near the end of production).
Of the 'Cosmetic' Vantage (for the US Swiss and Japanese markets, with fuel injection instead of Weber carburettors), 14 Series 2 coupés and 56 Volantes were built.
Cosmetic Vantages lacked the powerful Vantage engine but retained the Vantage name and most of its body alterations - though the lack of carburettors allowed a flattened hood.
From 1980 they featured DOT-approved 5 mph (8 km/h) safety bumpers front and rear.
Most of these cars have since been retrofitted with full power, European spec engines.

Although the full spec (carburettor) Vantage models were not imported into the USA when new, they now qualify for entry under the DOT's 'Show and Display' rules in most US States.
Federal requirements are also less strict for cars over 25 years old (as most Vantages now are).
