Concept Car of the Week: Mitsubishi HSR (1987)

In 1987, Mitsubishi initiated a range of concept cars called HSR (High Speed Research) with the intention of creating a futuristic vision for the brand combining advanced technology, efficient power and aerodynamic design. The first concept car was designed for safely cruising on the motorway at very high speed, thanks to cutting edge electronics. The car's internal computers measured speed, weather, driver input and grip, and adjusted the 4-wheel drive system and the 4-wheel steering automatically.
