The car was unveiled at the Tokyo Motor Show in 1991. It was the first in a series of demonstration hydrogen internal combustion engine vehicles produced by Mazda. DesignThe Mazda HR-X was a small concept car developed by Mazda to showcase the use of hydrogen fuel as a possible environmentally friendly alternative for automotive transport.[1] The car was powered by a two rotor Wankel engine that produced {{convert|100|hp|kW|abbr=on}}. 37 Nm3 ({{convert|3.32|kg|lb}}) of hydrogen was stored in a metal hydrite tank that was refuelled by a single nozzle alongside water for cooling.[2] The engine was connected to the wheels via a 4 speed automatic transmission, while a KERS-like system called Active Torque Control System (ACTS) was used to recover braking energy and reuse it to improve acceleration.[3] The cabin accommodated two people who entered via gull-wing doors. It was constructed of plastic and designed to be nearly completely recyclable. PerformanceThe car was capable of a top speed of {{convert|81|mph|km/h|abbr=on|order=flip}} and had a range of {{convert|120|mi|km||abbr=on|order=flip}}.[4] See also
