Bugatti - Bugatti Type 57
The Bugatti Type 57 was the 3.3 litre touring car built from 1934 which, in 1937 had a option of a supercharged version Type 57C (C for Compressor). Both these types were produced until the war started in 1939.
Bugatti also made the Type 57S model between 1936 and 1938 which was so different that I don't understand why it was not called by another model number! The chassis was shorter at 2.98 metres with a different frame altogether where the rear axle went through the frame. Jean Bugatti was desperate to have independent front suspension, but Le Patron forbade it, so the small compromise was the front axle that was split in the middle allowing some twist, One 57S was supplied with supercharger, called the 57SC, the other 57S that became supercharged being done subsequently, either by the factory or by later owners.
Bugatti 57 models were fitted as standard with 18" wheels and 550x18 tyres. Blockley makes the best 550x18 tyres available, which come in a choice of two tread patterns. Occasionally we see Type 57's with 19" wheels, and in this case we have the 19" tyres to suit also.
