Troubled carmaker General Motors is displaying the production version of its Chevrolet Volt - a vehicle that delivers up to 64 km of gasoline and emission-free electric driving.
The company has sold more than 80 F3DM electric cars, the first mass-produced model in the world, priced at around $22,000 each, to the Shenzhen government for tests before public use.
"We have cooperated with local government to set up around twenty 220V-charger pillars in parking lots around offices and residential areas," said Yang.
Hebei-based Great Wall Motor unveiled its GWKulla all-electric car, with plans to enter the market next year, while Chery debuted its concept battery car - the Riichi M1.
