Usually when we hear about hydrogen as a fuel, it's actually being used to generate electricity for an electric motor. It's no secret that Mazda's been developing a hydrogen powered version of its Renesis rotary engine for years, but now the automaker says that it will soon be mass-producing hydrogen powered vehicles. The rotary engine's unique design actually makes it well suited for using hydrogen as a combustible fuel.
Mazda's already built working hydrogen powered RX8s and Mazda5s, so we can see how that number could be realistic. With electric cars making huge strides and the hydrogen distribution infrastructure still lacking, it may be too little too late for Mazda's hydrogen rotaries by the time they reach the market.
Autocar's article also speculates about the potential for a hydrogen powered RX7 sports coupe revival. Lightweight? Fast? Green? Sign us up!
