The engine used the same light aluminium alloy construction as the old straight six and used a similar design for the valve gear employing two chain driven overhead camshafts per cylinder bank and two valves per cylinder. The 8 wet liner cylinders were in a V formation set at 90 degrees with fuel and air were supplied via a Bosch mechanical fuel injection system with the injector pump in the middle of the cylinder vee and eight separate throttle butterflies mounted outboard of each induction port. The engine had five main bearings and the cooling system was with thermostat, water pump and viscous-coupling fan.
Putting this newly developed engine into the body that had been created for it gave Aston Martin a car that carried four people in luxury, weighed well over one and a half tons, yet could accelerate from 0 - 60 mph in less than 6 seconds and had a top speed of 160 mph. Every aspect of the car needed superlatives for its description. With that weight and speed, the Girling brakes had to produce substantial stopping power - 1 ? inches thick front and rear, they were ventilated and had two independent hydraulic circuits to provide pressure to front and rear and the rear brakes had separate callipers for the handbrake. Unusually, Aston Martin made standard the fitment of specially made 15 inch alloy wheels with 7 inch rims.
Testing the car, a contemporary road test by Autocar noted the flexibility of the new V8 engine at the bottom end of its wide range. They noted that the torque curve was surprisingly flat noting that in fifth gear, the 20 mile per hour increments from 30 mph to 110 mph each took around 4 seconds less than the straight six it had tested the year before. They also noted that the clutch, having to cope with all the extra torque, was heavier than the six cylinder - they measured that it needed 50 pounds of force to depress the pedal. Handling and grip had been improved on the DBS with the de Dion rear axle - in the DBS V8.
