The approval will enable THINK to sell its electric THINK City in California, 12 other states and the District of Columbia that have adopted California’s ZEV requirements.

The THINK City, which has been designed for fleet applications and urban commuters, has a range of 100 miles that meets CARB’s Type II ZEV Tier requirements, and uses an advanced lithium-ion battery developed by Ener1.

THINK, which also builds the THINK City in Finland for sale in Europe, plans to expand THINK City production at its Elkhart, Indiana manufacturing facility and roll out retail distribution in select cities in the second half of 2011.

THINK spokesperson Brendan Prebo said that CARB certification is critical for fleet sales, not just in California, but in the other CARB states as well, as these states make up more than 35% of the automobile market in the US and represent a significant share of the fleet market.
