China's first plug-in hybrid,  BYD's F3DM, goes on sale today
 BYD got into the car market in 2003, and the F3DM is a  modified version of its gas-powered F3 model. The DM in the name stands for  dual-mode, reflecting its ability to operate in both full-electric and  gas-electric hybrid modes. The electric mode has a  range of 60 miles on a single charge.
 Among those betting on BYD  is Warren E. Buffett, who in September bought a 9.9% stake for $230  million. The billioniare investor apparently was impressed with  BYD's green technology and Wang's record as a manager.
