The Aston Martin RB6 is a 2.5-litre, naturally-aspirated, inline-6 racing engine, developed and designed by Aston Martin for Formula One racing; used between 1959 and 1960. [2] The RB6 also shared the basic double-overhead camshaft straight-6 Aston Martin engine design with its brethren, but sleeved to reduce its capacity to 2.5-litres. Although Tadek Marek's design was a reliable and powerful unit in its 3.7-litre road car form, the reduced capacity racing motor was hard-pressed to cope with the heavy chassis and poor aerodynamics, and frequent engine failures blighted the DBR4's brief racing career. Aston Martin claimed a 280 bhp (210 kW) output for the DBR4's engine. However, it was common practice at the time to overquote engine power, and a more realistic value is closer to 250 bhp (190 kW). This value is still higher than that provided by the Coventry Climax FPF straight-4, used by contemporary manufacturers such as Lotus and Cooper, but the Aston Martin engine weighed appreciably more. The engine drove the rear wheels through a proprietary David Brown gearbox, provided by Aston Martin's owners. [3] [4] [5]
The DBR5's engine was smaller and lighter. The new engine modifications meant that the power output was finally close to the figure originally claimed by the Aston Martin workshop. [6] [7] [8] [9] [10]
