Bugatti Type 51
Inspiration for this new design thinking came from two Miller racing cars that Jean Bugatti was testing for power output.The obvious external differences of a Type 51 are: the supercharger blow-off outlet is lower the bonnet in the louvered section; one piece cast wheels instead of bolted on rims; twin fuel caps behind the driver and finally the magneto being off-set to the left on the dash.[11][12] Grand Prix car of 1931, fitted with a twin overhead-cam 4.9-liter (4,972cc, 86 x 107 mm) engine delivering 300 hp (223 kW).The signature piano wire wheels used splines between the brake drum and rim, and relied on the radial spokes to handle cornering loads.The car had been used by the Bugatti racing team in 1934–1935 and being driven by René Dreyfus it won the Belgian Grand Prix in 1934.
