Electric cars are 1.1%, plug-in hybrids 0.7%According to stats compiled by the California New Car Dealers Association (CNCDA), hybrid cars now represent 7% of the market in California, with 59,300 units sold during the first half of 2013. That's up from 6.2% in 2012 and 4.8% in 2011. Somewhat surprisingly, pure electric cars are doing better than plug-in hybrids with 1.1% of the market and 9,708 units vs 0.7% and 5,736 units.
It's interesting to note that: "Tesla Motors took 0.6% share of the total new light-duty vehicle in California in the first half—more than Buick (0.5%); FIAT (0.5%); Land Rover (0.5%); Lincoln (0.3%); and Mitsubishi (0.3%)."
California is also a huge market for Tesla Motors (a company based in the state):
On the electric vehicle side, Tesla Motors posted 2,308 units of the Model S in California during the second quarter of 2013, representing 44.8% of the 5,150 units it reported sold during that quarter. (Earlier post.) For the first half of 2013, Tesla posted 4,714 units of the Model S in California, representing about 52% of its deliveries and representing 48.6% of battery electric vehicles sold in the state during that period.

This makes the Model S electric sedan the #3 top-selling brand in the luxury and sports segment in the first half of 2013, behind only the Mercedes E-Class and the BMW 5-Series.
