The Aston Martin V8 Vantage is a British grand tourer, a higher performance version of the Aston Martin V8. It was hailed at its 1977 introduction as "Britain's First Supercar" for its 170 mph (270 km/h) top speed. Its engine was shared with the Lagonda, but it used high-performance camshafts, increased compression ratio, larger inlet valves and bigger carburettors mounted on new manifolds for increased output. Straight-line performance was the best of the day, with acceleration from 0–60 mph (97 km/h) in 5.3 seconds, one-tenth of a second quicker than the Ferrari Daytona.
