Byd Co

With the Big Three automakers tottering and China's once go-go car market in reverse, this might seem a bad time for a relative unknown to be launching a new vehicle. Then again, BYD Co. isn't rolling out any ordinary car. On Monday, the upstart company best known for making cellphone batteries will begin selling its F3DM -- China's first mass-produced hybrid electric vehicle. The car is expected to retail for around $20,000 in China and make its way to U.S. shores in 2011.
