The Bugatti type 37A is a two seater Grand Prix racing car. The exterior is finished in a French racing blue, with highly polished horseshoe shape radiator and grill in German silver, featuring the Bugatti logo in the top centre. The radiator is flanked on either side by two headlights, bolted to the front mudguards and main body of the vehicle by a single rod. The Bugatti has two front and two rear tyres, designed in a spiralling spoke pattern with a spare tyre secured to the vehicles left hand side by a single leather strap.
The interior features driver and passenger seats made from wood and metal and upholstered in a soft light brown leather. The dashboard is finished in a finely polished metal and features a series of switches and gauges indicating the temperature and fluid levels of the vehicle as well as a wooden steering wheel with four metal spokes. Above the dashboard are two racing windscreens, made from glass and mounted in metal frames. There is a single side mirror in a metal frame on the right hand side of the vehicle.
The bonnet of the Bugattio is secured over the engine using two leather straps and can be opened up on both the left and right hand side or removed entirely. Underneath the bonnet features a four cylinder En Block single skew-driven overhead camshaft 1496 cc engine with three valves per cylinder made more potent with a Rootes supercharger. The transmission consists of a multi-plate wet clutch, straight cut sliding pinion gears with a right-hand outside gate change lever (4 forward and 1 reverse).
