57254roadFrance
Engine
Dual overhead cam inline engine, upgraded with revised pistons, special intake manifold, and adjusted valve guides and camshaft
Colour
Single monochromatic finish (repainted to original color after a prior two-tone black and red respray)

Bugatti Type 57 Atalante chassis 57254, assembled at Molsheim in spring 1935, is among the earliest examples of this rare coachwork style — technically the third Atalante built and one of only four prototypes. Bodied by Carrosserie Bugatti rather than the more commonly used Gangloff, it features distinctive details including a uniquely low roofline and forward-leaning rear spats. First delivered to two-time Targa Florio champion Meo Costantini, the car subsequently spent 62 consecutive years with a single French family before passing to French collector ownership. It retains its original matching-numbers engine, unmodified cable brakes, body panels stamped '3', and largely untouched interior, with a recorded total of just over 25,700 kilometres.
