context_page_description: This is a list of prototype vehicles created by Bugatti that never reached full production.
context_section_description: The  16-cylinder Type 45 racing car and similar Type 47 "Grand Sport" were to become a new generation of cars from Bugatti. The engine, a 3-valve SOHC design, was based on the 3-valve straight-8 from the Type 35. Two versions were made:  A 3.0 L (2986 cc/182 in³) version fitted to a Type 47 prototype shared the Type 36's 60 by 66 mm dimensions, while the Type 45 prototype used a unique 84 mm stroke for 3.8 L (3801 cc/231 in³). Output would have been 200 to 250 hp (149 to 186 kW) with a Roots-type supercharger in play.
  The entire vehicle was unique, including its chassis.  The Type 45 used a 102.2 in (2596 mm) wheelbase, while the Type 47 was stretched to 108.3 in (2750 mm).  Both had a 49.2 in (1250 mm) track.
