Today Mazda is one of the leading car manufacturing companies in the world but it wasn't until 1960 when the manufacturer was taken seriously as a car producer with its beautiful R360 coupe. This little vehicle was powered by a rear mounted and air cooled 356 cc engine which put out a whopping 16 hp with top speeds of about 52mph and weighed only 380 kg. The wheelbase was only 69 inches and as the photo taken at the Mazda Museum in Hiroshima shows it was very cute. Production lasted about 6 years, and in that time they did a few major upgrades and even produced a convertible version of the R360 from 1964 and also transformed the vehicle into a light pickup truck, the B360.
Unveiled at the 1993 Tokyo Motor show and now is on display at the Mazda Museum in Hiroshima Japan, the HR-X2 concept car featured a Hydrogen rotary engine. This car adopted metal-hydride to carry hydrogen fuel safely. Although range was only 150 miles a tank full it was considered a breakthrough with the new hydrogen fuel. The range was affected by the level of safety equipment required to transport the explosive fuel. Performance was as good as a normal family sedan. The body was also an environmental wonder with all of it being recyclable.
