Mitsubishi HSR

The Mitsubishi HSR, short for Highly Sophisticated-transport Research, is a range of concept cars that Mitsubishi Motors exhibited through the late 1980s and 1990s, with six distinct iterations shown every two years at the Tokyo Motor Show. The acronym changed over time: Hi-speed Running Research for the first, Hi-Sophisticated Research for the second and Human Science Research for the third. The 1987 HSR showcased integrated electronic control of drivetrain, suspension, steering, brakes and driving position, with a 2.0 litre 16-valve turbo engine of 295 PS and a claimed 300 km/h. The 1989 HSR-II stressed active aerodynamics, the 1991 HSR-III used the 180 PS 6A10 1.6 litre V6, the smallest mass-produced V6, the 1993 HSR-IV was a four-wheel-drive sports car, the 1995 HSR-V debuted gasoline direct injection and the 1997 HSR-VI had a 2.4 litre GDI engine, four-wheel steering and an automated driving system. Much of the technology reached the HSX and the GTO.
