Why it matters
The Type 45 and Type 47 were Bugatti's 16-cylinder cars – a competition car and a Grand Sport – and only two were made. Apart from axles and some engine parts nearly everything on them was unique, making them among the most ambitious and least-produced Bugattis of the vintage era.

02Production & history
Production
Every figure says what it counts.
| What is counted | Figure | Basis | Status |
|---|---|---|---|
| Total model productioncars made | 21 | Factory production | Independently researched |
Independent counts (e.g. engine and colour) are never combined into a calculated figure. Surviving examples are never presented as original production.
History
Built around 1929–30, the cars used a 16-cylinder engine with two crankshafts geared together, three valves per cylinder and a rear-mounted twin Roots supercharger. The Type 45 engine displaced 3801 cc for about 250 bhp, while the Type 47 Grand Sport used a shorter-stroke 2986 cc version of about 200 bhp and a longer 2.75 m wheelbase.
