The Bugatti Type 57 and later variants (including the famous Atlantic and Atalante) was an entirely new design created by Jean Bugatti, son of founder Ettore. Type 57s were built from 1934 through 1940, with a total of 710 examples produced.
Type 57s used a twin-cam 3,257cc engine based on that of the Type 49 but heavily modified by Jean Bugatti, unlike the single cam engines of the Type 49 and earlier models. The engines of the Type 50, 51 used bevel gears at the front of the engine to transmit power from the crankshaft, whereas the Type 57 used a train of spur gears at the rear of the engine, with fiber gear wheels on the camshafts to achieve more silence in operation.
The Bugatti Type 57S Atalante number 57502, built in 1937 by Automobiles Ettore Bugatti, is one of 43 Bugatti Type 57S made and one of only 17 Type 57S produced with the in-house Atalante coupé coachwork. The car hit the headlines in 2009 when auctioned by Bonhams, after having been rediscovered in 2008, following 48 years of storage in a private owner's garage in Gosforth, England, with few people aware of its location.
