SAN FRANCISCO – Green Fleet had the chance to drive the pre-production version of the Chevrolet Spark EV during the GM Electrification Experience in Sausalito, Calif. The media event, which took place Nov. 14-15, provided approximately 50 journalists in attendance with an up-close look at the motor, battery, and mobile applications featured on the new model.

Scheduled to debut at the upcoming 2012 LA Auto Show, the Spark EV boasts 400-lb.-ft, torque and goes from 0 to 60 mph in eight seconds and accelerated smoothly. GM officials noted that the vehicle’s power even rivals some performance models.

The Spark EV will feature a more than 20 kWh lithium-ion battery pack, which will have a warranty of eight years/100,000 miles, and is capable of handling multiple DC fast charges daily. GM said a user can also charge the vehicle in less than seven hours using a dedicated 240V charge. A 120V charge cord is standard with the vehicle, according to GM. The automaker added that a driver can remotely manage and monitor charging using an OnStar smartphone application specific to the Spark EV. More than 75 percent of the Spark EV’s electric propulsion technology actually descends from the Volt’s and GM’s hybrid truck program, the automaker noted.

For charging, GM plans to offer an industry-first SAE combo charger for the Spark, which allows DC fast charging of up to 80 percent of the vehicle’s full charge in approximately 20 minutes.

GM plans to manufacture the Spark EV’s motor and drive unit at GM’s transmission plant in White Marsh, Md., starting in early 2013. According to the automaker, this is the first time a U.S. auto manufacturer has built a complete electric motor and drive unit for a modern electric vehicle in the U.S.

In addition to the Spark EV, GM also had several other models in its “electrified” lineup on site for journalists to drive, including the Chevrolet Volt, Buick LaCrosse eAssist, and the Opel/Vauxhall Ampera (shown below). 

GM plans to have up to 500,000 vehicles equipped with electrification technology on the road by 2017, Mary Barra, senior vice president of global product development, told attendees. “Our major strategy will focus on [plug-in technology],” she said.

The automaker is also leveraging all sources of technology — internal and external from startups and suppliers — to provide vehicles with higher performance and lower costs, according to Jon Lauckner, vice president and chief technology officer.

“Next-generation EVs need higher capability and lower cost technology solutions, not just scale,” he emphasized to attendees. “We have to ensure any battery technology we offer will deliver of vehicle life. Developing advanced technology is a priority.”
