Subaru is one of Colorado’s favorite car makes, but you won’t be able to get one that plugs in for a while.

Subaru is planning to release its first plug-in hybrid powertrain on its Crosstrek models “in limited quantities,” but only in the 10 states that have adopted zero-emissions vehicle requirements, Colorado dealerships are telling customers.

States with zero-emissions vehicle (ZEV) rules are California, Oregon, New York, New Jersey, Connecticut, Massachusetts and other states in the Northeast.

The program started in California and requires automakers to provide a number of electric cars and trucks based on the company’s overall sales in that state. The goal is to get automakers to research, develop and market electric vehicles.

Conservation Colorado was dismayed by the Subaru news on Tuesday, and so was Will Toor, the transportation program director for the Southwest Energy Efficiency Project in Boulder.

“Despite the fact that Colorado has some of the strongest consumer demand for electric vehicles, most car manufacturers don’t sell all their electric models here,” Toor said. “States that have adopted zero emission standard get up to three times as many models. The new plug-in hybrid Subaru Crosstrek is a great example.

“What could suit the Colorado lifestyle more than an all-wheel drive electric vehicle? But Subaru is only planning to release it in the ZEV states. Colorado needs to take action to increase model availability.”

That means tougher air-quality standards.
