Toyota has always been the front-runner in creating environmentally friendly cars, and now they're doing it again with their as-yet-unnamed car -- set to roll out in 2015 -- that is powered by hydrogen and will emit water vapor as exhaust.

According to The Seattle Times, "the Japanese automaker made the announcement Monday at the International Consumer Electronics Show (CES), the technology industry's annual gadget exposition. The shift came months after rival automakers Hyundai and Honda both said they'd start selling cars with that technology in the U.S. in 2015. The electric car, which Toyota calls FCV for now, uses hydrogen as fuel for a battery. Toyota says the vehicle will have a range of 300 miles, can accelerate from standstill to 60 mph in 10 seconds, and can refuel its hydrogen tank in three to five minutes. Toyota says it will focus on selling hydrogen cars in California at first."

Furthermore, according to The Business Times, "Toyota unveiled a prototype last year at the Tokyo auto show, but on Monday offered more details for its plans for the US market.

"Honda is also expected to roll out a fuel-cell car in the US market in 2015, and other automakers are working on the technology, which emits only water vapor as exhaust.

"Honda already has a fuel-cell car, the FCX Clarity, available on a small scale in a limited number of markets.

Bob Carter, Toyota's vice-president of marketing, said that Toyota and California officials plan to add 20 new fuel stations by 2015 to the 10 existing ones. The goal is to have about 100 in the state, and to have a station within a six-minute drive of an owner's home or business. 'This infrastructure thing is going to happen,' he said. 'I believe this vehicle will be the car of the future.'

The Business Times reports: "It is expected to launch in Japan at about the same time."
