92:. They were heavily rationalized engines, which made use of as many common parts across the range as possible, for example, the 8 cylinder versions used 2 sets of the oil bath air filters, exhaust manifolds and points components of the 4 cylinder, while using the same carburettor as the 6. Pistons, rods, valves, springs, liners, etc. were common across the range, until the introduction of the overbored xx1 series, which still attempted to use as many common components as possible.

the engine, different accessories may also be installed so, for example, a B80 Mk 6A from an Alvis
Saracen is not directly interchangeable with a B80 Mk 6A from an Alvis Saladin, as the Saladin is fitted with a high output 70A generator, and has different mounts for the engine, water piping, accessories and hydraulic system.
679:, in their Vanwall Specials. In race trim, these engines produced 290 bhp at 7,500 RPM when running on alcohol, and after a rule change in late 1957, this was reduced to about 260 bhp on 130 octane aviation fuel. Despite this, the cars were moderately successful, earning the constructor's championship in 1958.
95:
The engines were designed to produce relatively high power outputs (for the time), while being extremely reliable and running on low grade "pool" petrol. They were designed to be simple to maintain, with washable oil and fuel filters, mechanical fuel pumps and could all be started via a hand crank.

B40 engines were required in large numbers for the
British Army contract to build 15,000 ¼ton "Champs" over four years (1951-1956) plus spare engines and parts, and a further 400 vehicles for the Australian Army. Rolls-Royce were unable to cope with production at this rate and the Austin Motor Co

was fitted with the B60 Mk 3A in early production and the B60 Mk 6A in the later production examples. The table below details the main differences between the marks, but there were also minor differences, such as changes to pulley configurations and accessories as well. Depending on the fitment of

were granted a licence to produce B40 Mk.5A engines, and also loaned tooling. The majority of Champs produced were fitted with Austin-built engines which are identified by 5-digit serial numbers.

The engines were available in 5 main models, which were fitted to small to medium tactical vehicles, up to about 13 tonnes in mass. They were also used in some fixed and mobile plant equipment.

British Army's wheeled vehicles.

Due to their low compression ratios and hardened valve seats, the B range of engines are suitable for use with unleaded fuel, without modification.

British Military vehicles with collectors, many Rolls-Royce B range engines are still in use.
