The Bugatti Type 55 is a sports car produced by Bugatti from 1932 to 1935. It is a road-going version of the Type 51 Grand Prix car. A roadster, it had a 108.3 in (2750 mm) wheelbase and 1800 lb (816 kg) weight.
The Type 55 is powered by a detuned version of the Type 51’s 2.3 L (2262 cc/138 in³) 2-valve DOHC straight-8 engine with a Roots-type supercharger. It produces 130 hp (96 kW) at 5000 rpm. Differences from the Type 51’s engine include the addition of a camshaft driven AC mechanical petrol pump and a modified supercharger drive.
The compression ratio was also lowered by the use of a larger 9 mm (0.3 in) compression plate (the Type 51 used a 6 mm (0.2 in) plate). The car’s 4-speed manual transmission came from the Type 49 touring car and featured straight cut gears. The car also wore the signature Bugatti eight spoke aluminum wheels.
