YOKOHAMA, Japan – Nissan showed off its Leaf electric car Friday, trumpeting its zero-emission technology and practicality with video of the hatchback zipping through snow and water.

The car, among the world’s first mass-market electric vehicles, is already sold out until March 2011 because of limited production capacity. There have been 6,000 orders in Japan and 20,000 in the United States. It arrives in Europe next year.

“This day has finally arrived,” Nissan Motor Co. Chief Operating Officer Toshiyuki Shiga said, before posing for photographs with Japanese customers who had placed orders for the Leaf. “The curtains are about to rise for a new era in the auto industry.”

Shiga said the Leaf will sell in Japan for $45,000 but with a $9,000 government green incentive the price will come down to $35,000.

The manufacturer’s suggested retail price in the United States is $33,600. Some states offer incentives and rebates for the electric car, and a taxpayer can claim a $7,500 federal tax credit for purchasing a Leaf in the United States.

Shiga acknowledged that production won’t keep up with demand for a while and some customers are going to have to wait months for the Leaf.

The Leaf is now being produced only in Japan with production capacity at 50,000 a year, but production is due to start in the United States and Great Britain in 2012 and capacity will rise to 250,000 vehicles, according to Shiga.

Yoshihiro Maruyama, 67, a retired farmer, said he was not happy about having to wait until February for his Leaf but he was thrilled about being a future owner.

“I wanted to be the first to drive it,” he said. “You can charge this thing at home.”

Nissan also showed how it was working with apartment complexes and community groups to encourage widespread adoption of electric vehicles through car-sharing and partnerships with local governments.

The big sticking point is the need for charging stations and other infrastructure.

Rempei Matsumoto, author of a book about green vehicles, believes the Leaf is for now little more than an image perk for Nissan. Experimentation in electric vehicles dates back decades but their consumer use is expected to be limited for years, he said.

“They can only be used for limited distances such as picking your kid up from kindergarten or going grocery shopping,” he said in a telephone interview.

A good compromise may be gas-electric hybrids such as Toyota Motor Corp.’s hit Prius, which travels a limited distance on the electric motor but never runs out of a battery charge because it also has a gasoline engine.

Toyota is introducing an electric version of the iQ ultra-compact in 2012 and is working with Tesla Motors Inc. on an electric RAV-4 sport utility vehicle. Honda Motor Co. sells three hybrids, the Insight, CR-Z and Fit, and plans an electric vehicle in 2012.

Even Nissan, long upbeat on electric vehicles, has recently come out with its own hybrid, the luxury Infiniti M.
