The Cooper Mark II, also known as the T5 (Type 5), was a 500cc (predecessor to Formula 3) open-wheel racing car designed and built by the Cooper Car Company at Surbiton, Surrey, England, in 1948, and was the first production car made by Cooper. It was a successor to 1946 Cooper 500, which was a prototype. 12 cars were built. It was powered by a 45 hp (34 kW)500 cc (31 cu in) JA Prestwich Industries (JAP) 4B Speedway single-cylinder engine, but had the option of being converted to a lengthened wheelbase version, to be able to use a 70 hp (52 kW)1,000 cc (61 cu in) JA Prestwich Industries (JAP) or Vincent-HRD V-twin. It also notably won the first ever Grand Prix at Silverstone in 1948, competing in the 500 cc class, being driven by Spike Rhiando. [1] [2]

<span class="mw-page-title-main">BMC A-series engine</span> Motor vehicle engine

The Austin Motor Company A series is a small straight-4 automobile engine. Launched in 1951 with the Austin A30, production lasted until 2000 in the Mini. It used a cast-iron block and cylinder head, and a steel crankshaft with 3 main bearings. The camshaft ran in the cylinder block, driven by a single-row chain for most applications, and with tappets sliding in the block, accessible through pressed steel side covers for most applications, and with overhead valves operated through rockers. The cylinder blocks are not interchangeable between versions intended for conventional end-on mounted gearboxes and the 'in-sump' transaxle used on BMC/BL front wheel drive models such as the Mini. The cylinder head for the overhead-valve version of the A-series engine was designed by Harry Weslake – a cylinder head specialist famed for his involvement in SS (Jaguar) engines and several F1-title winning engines. Although a "clean sheet" design, the A series owed much to established Austin engine design practise, resembling in general design and overall appearance a scaled-down version of the 1200cc overhead-valve engine first seen in the Austin A40 Devon which would form the basis of the later B-series engine.
