The Mitsubishi HSR (Highly Sophisticated-transport Research) is a range of concept cars exhibited by Mitsubishi Motors through the late 1980s and 1990s. There were six distinct iterations of the vehicle released biannually to coincide with the Tokyo Motor Show, with each model after the original identified by a Roman numeral suffixed to the name.
- HSR (1987) — The first vehicle was a showcase for Mitsubishi's integrated electronic systems offering automatic control of drive train, suspension, steering, brakes, and driving position according to driving conditions or weather. It was powered by a 2.0-litre 16-valve turbocharged engine producing 295 bhp (220 kW; 299 PS), had a maximum speed claimed by the factory at 300 km/h (186 mph).
- HSR-II (1989) — The second generation had a heavy emphasis on active aerodynamics, with a series of movable fins and spoilers offering a drag factor which varied from 0.20 to 0.40 depending on setup. Much of the technology found its way to the Mitsubishi HSX, the precursor to the company's GTO sports car. It is also featured in the games Gran Turismo 4, Gran Turismo 5 and Gran Turismo 6.
- HSR-III (1991) — The third concept car to bear the HSR name was powered by the 6A10 1.6-litre V6, the world's smallest mass-produced V6.
- HSR-IV (1993) — A 180 bhp (134 kW; 182 PS) modulated displacement version of the 1.6-litre V6 powered the fourth prototype, a four-wheel-drive sports car featuring an all-wheel anti-lock braking system.
- HSR-V (1995) — The fifth generation, a targa topped sports car with a folding hardtop roof, featured the debut of Mitsubishi's gasoline direct injection (GDI) technology in its ICDIGE engine.
- HSR-VI (1997) — Fitted with a 2.4-litre version of the GDI engine, the sixth HSR concept featured four-wheel steering, active yaw control, traction control and an automated driving system.
