A look at registrations shows that 5,736 plug-in hybrids were registered in California in the first half of 2013 and 9,708 pure electrics were registered.

A further examination of the figures released by California Auto Outlook shows that Tesla captured 0.6% of California's light-duty passenger vehicle segment in the first half of 2013.  At 0.6%, Tesla, with its lone vehicle, surpassed Buick (0.5%), FIAT (0.5%), Land Rover (0.5%), Lincoln (0.3%) and Mitsubishi (0.3%).

As Green Car Congress points out:

"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.  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."

So, Model S sedans accounted for nearly half of the pure electric vehicles sold in California in the first 6 months of 2013.  That's impressive, especially when one considers how much a Model S costs when compared to the other pure electrics available.
