It was the first time the external design was shown of Nissan Motor Co.'s environmentally friendly automobile, set to go on sale in Japan, the U.S. and Europe next year. The blue hatchback had a sporty design and a recharging opening in the front.
Designer Shiro Nakamura said the vehicle was intentionally designed to avoid a stereotypical futuristic design.
"This is not a niche car," he said. "We didn't make it unusual looking. It had to be a real car."
Nissan has promised that the Leaf, which goes into mass-production as a global model in 2012, will be about the same price as a gas-engine car such as the 1.5 million yen ($15,000) Tiida, which sells abroad as the Versa, starting at about $10,000.
The car has a range of 100 miles on a single battery charge, according to Nissan. The company is targeting initial annual production of 50,000 units for the Leaf at its Oppama plant in Yokohama, including export models.
Ghosn drove out on stage with former Prime Minister Junichiro Koizumi sitting next to him, and a Yokohama governor and mayor in the rear seats.
"This car represents a real breakthrough," Ghosn told reporters and guests in the new headquarters' showroom.
He said the new car and new office building in Yokohama, southwest of Tokyo, marked two fresh starts for Nissan, which hopes to take the lead in zero-emission vehicles.
Nissan, which has an alliance with Renault SA of France, has fallen behind Japanese rivals Toyota Motor Corp. and Honda Motor Co. in gas-electric hybrids that have become increasingly popular recently.
Nissan said the new 22-story headquarters was designed to be energy-efficient to qualify as one of the most ecological buildings in Japan. The company, which is losing money amid the global downturn, is selling its old Tokyo headquarters as part of efforts to cut costs.
Koizumi said environmentally friendly auto technology holds the key to Japan's economic growth.
"It was so unexpectedly smooth and quiet," he said after getting out of the car. "I am sure this car is going to be popular."
Nissan received a $1.6 billion loan from the U.S. Department of Energy to modify its Tennessee-based plant to produce electric vehicles and batteries to power them, with production starting in 2012.
Other carmakers, including U.S.-based Tesla Motors, are also racing to make electric automobiles.
In June, Nissan's smaller Japanese rival, Mitsubishi Motors Corp., launched its electric vehicle, the 4.59 million yen ($48,300) i-MiEV. The company has acknowledged that may be too expensive for most consumers.
Toyota has said it plans to sell electric vehicles in the U.S. by 2012. Chinese automaker Dongfeng Motor Corp. has teamed up with a Dutch-based company to develop and make electric cars.
Ghosn said Nissan's electric vehicle will get a boost from the interest of governments around the world, adding tougher emissions regulations were expected to increase market share of such cars to 5 percent. Hybrid models only make up about 2 percent of the auto market now, he said.
