Toyota has said for many years that it plans to build and sell a hydrogen fuel-cell vehicle, and now the company has trickled out some more information on that car.

Specifically, it provided images of the final production version's exterior design--little changed from the concept it showed at the Tokyo Motor Show in October 2013--along with on-sale dates and the price in Japan.

The Toyota Fuel Cell Sedan will be launched "before April 2015" in its home market of Japan, and the company is preparing to introduce the car in both the U.S. and Europe roughly a year hence, in the summer of 2015.

In November this year, the car's official model name was revealed: It will be the 2016 Toyota Mirai, which means "future" in Japanese.

In Japan, the hydrogen-powered Toyota will carry a price of "approximately 7 million yen" before tax (roughly $68,700), and will first be sold only in those regions where hydrogen fueling infrastructure exists.

The company noted in its press release that additional information--including interior design, specifications, exact prices, and sales targets--will come later.

Toyota put its first hydrogen test vehicles on the road roughly 20 years ago, and since 2002, it has been testing a fleet of Toyota Highlander Fuel Cell crossover utility vehicles in North America and other markets.

Curiously, a model name for the revolutionary new Toyota was not specified in the company's release.

Toyota introduced a new model name, Prius, for its first hybrid-electric vehicle when that car went on sale in Japan back in 1997, but thus far, its hydrogen car is just referred to as "Fuel Cell Sedan."
