Zero emissions, hydrogen fuel cell cars now on the road The first Honda FCX Clarity customers have taken delivery of their zero emission cars in California. Up to 200 customers will begin leasing the fuel cell vehicles in the United States and Japan over the next three years.

Film director Ron Yerxa was the first customer to get the keys to an FCX Clarity, followed by actress Jamie Lee Curtis and her husband, Christopher Guest. HONDA FCX

"I really wasn't expecting it to be so luxurious," said Curtis. "I love the interior layout, design and access to controls. It is user friendly and very modern." HONDA FCX

The FCX Clarity is Honda's next generation, hydrogen-powered fuel cell vehicle. Driven by an electric motor that runs on electricity generated by a fuel cell, the car's only emissions are heat and water. Its fuel efficiency is three times that of a modern petrol engine.
