Honda launched production of its first hydrogen-powered vehicles on Sunday in Tochigi, Japan. The four-door sedan, called the FCX Clarity, runs on electricity from a fuel cell battery that is powered by hydrogen fuel.
Steam is the hydrogen car’s only byproduct. The car can get a combined (city and highway driving) fuel efficiency of about 72 miles per kg of H2 which, according to Honda’s own estimates, is the equivalent of getting about 74 mpg on a gas-powered car. The car can be driven for about 280 miles before needing to be refueled.
