Concept vehicles are a highlight of the ongoing Guangzhou auto show in Guangzhou, South China's Guangdong province.

Green energy cars have been in the spotlight at the expo, where visitors can not only see the latest models, but also batteries and engines.

Some exhibitors even provide visitors with the opportunity to experience the joy of being on the road with a driving simulator.

This year's Guangzhou auto show runs from Nov 19-28 in China, the world's largest market for electric cars and plug-in hybrids.
