Aston Martin V8 Vantage Volante
From Aston Martin press: The V8 engine having proved to be an exceptionally reliable and robust unit, it was clear that there was scope for a significant increase in the power that it could deliver.
The Aston Martin V8 Vantage was announced on 18th February, 1977. Revised camshafts, air-box, larger inlet valves and carburettors, new inlet manifolds and different plugs, claimed to provide an increase in power of 40% and 10% more torque. The same ZF manual gearbox as in the V8 Saloon was standard equipment.
The power increase meant that aerodynamic improvements had to be made. This included a spoiler on the tail, a deep spoiler under the nose and blanked off rediator and bonnet air scoop.
