Aston Martin's single-overhead-cam engine with a Bore/Stroke of 69.3 mm x 99 mm, had first been seen in the 1927 models, was highly efficient and now had an output of 70 brake horsepower (52 kW) at 4750 rpm from 1.5 litres, an outstanding development by early 1930s standards.

The aluminium body was mounted on a separate steel chassis which had beam axles front and rear with semi-elliptic leaf springs.

During 1932 the Aston Martin International Le Mans had slowly sold at £650; the 1933 Aston Martin Le Mans model retailed at £595, thereby increasing the chance of the car selling faster.

The cars were long, low and immediately recognisable by their unique radiator style.

According to the standards of the early 1930s, Aston Le Mans were speedy cars – compared to the pace of the MG and Singer- with a top speed in the region of 85 mph (137 km/h) and acceleration from 0–50 mph (0–80 km/h) in 16 seconds.
