Wrightspeed, a maker of electric hybrid powertrains for trucks founded and run by Tesla co-founder Ian Wright, has relocated from San Jose to Alameda.

The company expects to grow by a factor of more than 12 to more than 300 employees by 2018.

Wrightspeed on Tuesday said it had moved into the city-owned 110,000-square-foot historic Hangar 41 at the former Alameda Naval Air Station. Wrightspeed plans to invest $3 million in the plant, where its "range extender" products will be assembled.

Wrightspeed says its plug-in hybrid powertrains, which generate electricity through regenerative braking, are designed to replace components in existing medium and heavy-duty commercial trucks. The change makes the vehicles "near zero-emission, quiet, and efficient commercial vehicles."
