The company was founded in 1914 by Lionel Martin and Robert Bamford. The company name was derived from the fact that Lionel Martin raced specials at the Aston Clinton hill climb. Their first car was built in 1915 and was referred to as the Coal Scuttle. Three more prototype cars were built, chassis number A3 was the third Aston Martin ever built and is the oldest in existence with a 1.5 litre 11 hp four cylinder side valve. In 1923 it was able to lap Brooklands at 84.5 mph.
Two Grand Prix Team cars (TT1 and TT2) were built for Count Zborowski to compete in the 1922 Isle of Man TT (although they were not ready in time) Originally featuring a engine with twin camshafts and 16 valves, the cars were then fitted with the Benson Twin Cam engines. This was designed by The Hon. John Benson as a new power unit for the cars just before Bamford and Martin called in the receivers in 1925. A total of approx 61 cars were built during this era, insufficient to save the company.
Featured elegant coachwork designed by Touring of Milan, Italy. The handmade, aluminum bodywork panels were mounted on a steel tube frame, using the Superleggera (meaning: super light) method of construction. All round disc brakes fitted, made first by Dunlop and later on by Girling. There were five series of the DB4, each series introduced changes and improvements to the original series one cars. Early cars have a mesh grille and simpler bumper design. Later cars are longer and consequently heavier than early cars, some late series five cars had DB5 style headlamp covers.
All DB4s were powered by a new six cylinder, all aluminum, 3670cc engine designed by Tadek Mereck, developing around 240bhp. The DB4 offered excellent performance for the time, 140mph top speed and 0-60 in 8.5 seconds. Overdrive transmission on most cars, the gearbox was produced by Astons' owner, David Brown. A Vantage engine was also available, offering even higher power outputs.
