This is the 1989 Mitsubishi HSR II prototype, the second iteration in a series of 6 different HSR (Highly Sophisticated Transport Research) prototypes, which debuted every two years at the Tokyo Motor Show starting in 1987 with the HSR I. These prototypes were built to conduct testing and research on different aspects of engineering include new technologies, energy saving capabilities, aerodynamics, driving assistance, and much more. The most daring and perhaps most interesting of the HSR vehicles is this car shown here, HSR II. After the success of the HSR I, a new evolution of the series was presented in 1989. Notably, one of the most interesting features on the HSR II is the presence of active ailerons which, depending on the driving conditions, can modify the air being transferred over the car in order to improve the aerodynamics and driving experience. The interior of the HSR II prototype reveals a complex control center, absolutely packed with buttons, screens, switches and the presence of a traditional steering wheel, which was not the case for the previous HSR model. The body itself, which was developed using kevlar and polycarbonate materials, is quite an attractive shape, which includes a tremendous roof canopy that tilts forward combined with traditional doors to make for a unique entry into this space-ship like vehicle. All of the HSR prototypes are believed to have been functional vehicles, which wasn’t necessarily common for the time period. Most if not all of the red areas on the car are part of a Active Aero Control system which includes an automated front splitter, movable canards, and of course the rear panels which raise and lower depending on the trajectory of the vehicle. The HSR II’s on-board computer system known as OCS-II (Overall Operation Cybernetic Control System) gives off information which allows the HSR II to adjust it’s aerodynamics and controls, optimizing the overall driving experience.
