Why it matters
The EX-7 was a fully operational concept car shown at the 1970 Tokyo Motor Show, built on the chassis of a Toyota Group 7 racing car. It explored what a supercar based on competition underpinnings might look like.

Independent counts (e.g. engine and colour) are never combined into a calculated figure. Surviving examples are never presented as original production.
History
Toyota's Group 7 programme began in autumn 1967. After the 1968 Type 415S and 1969 Type 474S, Toyota laid down five chassis for the turbocharged Type 578A. Plans were hit when the 1970 Japanese Grand Prix was switched to Formula 1 cars, and a Turbocharged 7 was fatally crashed by Minoru Kawai in August 1970; the Group 7 project was abandoned soon after.
The leftover chassis became the EX-7, the fifth EX-branded Toyota after the EX-I to EX-III of 1969. Toyota showed it at the Tokyo Motor Show held from 30 October to 12 November 1970, where Toyota's own history describes it as a high-speed touring sports car for intercity travel. Only one was built and it has not been seen in public for many years, according to Supercar Nostalgia.
