At first, it will only available at GM’s Shanghai vendors. The launch of the Sail model is part of GM’s wider eco-friendly car strategy in the world’s biggest auto market. Beijing introduced a policy to increase the number of eco-friendly cars on the road to 5 million by 2020, which has spurred carmakers to explore the potential of electric and plug-in hybrids. Two weeks ago SAIC rolled out its Roewe E50 electric car, costing roughly US$37,700. GM launched a plug-in hybrid, the Chevrolet Volt, earlier this year in China.
