GM, the first domestic automaker to build electric motors and drive units in the United States - designed and developed the Spark EV motor and drive unit to produce 140 hp (105 kW) and 400 lb-ft of torque, accelerating from 0 to 60 mph in 7.6 seconds. The Spark EV will be sold in California and Oregon this summer. (Photo by Mark Finkenstaedt for General Motors)
