The 1978 Aston Martin V8 was largely similar to the previous year’s model, with only minor changes made. It continued to be powered by a 5.3-liter V8 engine that produced 305 horsepower and 345 lb-ft of torque. The engine was mated to a 5-speed manual transmission.
One of the key changes for 1978 was the introduction of a limited edition V8 Vantage model, which featured a higher-performance version of the standard V8 engine with revised camshafts and larger carburetors, boosting horsepower to 375. The Vantage also featured aerodynamic improvements, including a rear spoiler and front air dam.
Other changes for the 1978 model year included revised exterior styling, with new bumpers and a revised grille design. The interior was also updated with new leather upholstery options.
