The Bugatti Type 57 Atlantic was an entirely new design by Jean Bugatti, son of founder Ettore. Type 57s were built from 1934 through 1940, with a total of 710 examples produced. Just two supercharged Type 57SC cars were built new, but most 57S owners wanted the additional power afforded by the blower. Therefore, most of the original Type 57S cars returned to Molsheim for the installation of a supercharger, pushing output from 175 hp (130 kW) to 200 hp (150 kW) and 120 mph (190 km/h). The Type 57SC is also the most expensive car ever purchased at auction, when an anonymous bidder spent an estimated 30 million dollars at the Gooding Classic Car Auction on May 5th 2010.Atlantic. Considered by some to be the most beautiful pre-war car, the Atlantic body Type 57S featured flowing coupe lines with a pronounced dorsal seam running front to back. It was based on the “Aerolithe” concept car of 1935. Like the Type 59 Grand Prix car, the Aérolithe used Elektron (a magnesium alloy) or Duralumin (an aluminium alloy) for its body panels. Therefore, the body panels were riveted externally, creating the signature seam. The production Atlantics (just four were made) used plain aluminum, however. But the dorsal seams were retained for style, and have led to the car’s present fame. Only two of the cars survive. One is in the collection of Ralph Lauren, the second was owned by Dr. Peter Williamson, and won the 2003 Pebble Beach Concours d’Elegance. Williamson’s car was sold for between $30 and $40 million at an auction in May 2010 to the Mullin Automotive Museum located in Oxnard, California. This exquisite 1:18 scale model was handmade with amazing attention to detail.
