This HAI -- that's "shark" in German -- was created after Swiss car designer Peter Monteverdi paid a visit to Chrysler in Detroit. While there, a 426 Hemi engine caught his eye, so Monterverdi decided to build a car around it. The 450 horsepower engine Chrysler ultimately produced was, in turn, created specially for this car.
The Monteverdi HAI showcar, in "Purple Smoke" metallic paint, was unveiled at the 1970 Geneva Motor Show. Able to reach 100 miles per hour in about 12 seconds, it was one of the fastest cars ever produced for street use up to that time.
