Why it matters
The twin-turbocharged Toyota 7 was built for the North American Can-Am series but never raced, because a 1970 change in Japanese Grand Prix rules made the programme impractical.
How rare is it?
Six separate kinds of rarity – never combined into one number.

History
For 1970 Toyota developed a twin-turbocharged 5-litre V8 version of the 7 aimed at the North American Can-Am series. Five chassis were laid down and three complete turbo cars assembled. After Minoru Kawai was killed testing at Suzuka in August 1970, and with the Japanese Grand Prix changing format, the programme was abandoned and the car never raced. The three cars went to Toyota's museum.
