Mitsubishi HSR

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. The meaning of the acronym varied over the years. The first iteration meant Hi-speed Running Research, the second Hi-Sophisticated Research, and the third Human Science Research.
