The heart of the Spark EV’s propulsion system is the GM-designed, oil-cooled, permanent magnet motor. Putting more than half a million road miles on development versions of the Spark EV enabled engineers to optimize the performance of the motor by using a specifically designed bar-wound copper stator and unique rotor configuration.
The Spark EV electric motor will produce 130 hp (100 kW) and 400 lb-ft of torque to deliver acceleration of less than 8 seconds from 0 to 60 mph. The Spark EV will be sold in California and Oregon this summer and sales will expand to Canada, Europe and South Korea later.
Electric motor development and manufacturing is a critical area of expertise GM has mastered as we grow our portfolio of electric vehicles to address the needs of our global customers.—Larry Nitz, GM executive director of Vehicle Electrification Engineering
