The Mazda HR-X was the first hydrogen powered concept car produced by Mazda. The car was unveiled at the Tokyo Motor Show in 1991. The car seated four people in a plastic shell and was powered by a two rotor Wankel engine which propelled it to 130 km/h (81 mph). The hydrogen was stored in a cooled metal hydride tank and 3.32 kilograms (7.3 lb) provided a range of 190 km (120 mi). It was the first in a series of demonstration hydrogen internal combustion engine vehicles produced by Mazda.
