Bugatti Type 45, by Wouter Melissen - Ultimatecarpage.com
The 16-cylinder Bugatti 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:
1. A 3.8 L (3801 cc/231 in³) version for the Type 45 prototype which used a unique 84 mm stroke. Output would have been 200 to 250 hp (149 to 186 kW) with a Roots-type supercharger in play.
2. 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.
The entire vehicles were unique, including the 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.
