News Trends \\\ Breakthroughs \\\ Developments GM Debuts Pure-Electric Spark GM's Spark EV could be the first to employ the new DC fast-charging standard. Unveiled at the Los Angeles Auto Show, the 2014 Chevrolet Spark EV uses a GMdesigned, coaxial drive unit and electric motor that deliver 130 hp and 400 lb-ft of torque. general motors rolled out the battery-pow- ered Spark EV, marking the first time it has introduced an all-electric car since it scrapped the infamous EV1 a decade ago. The $25,000 mini-car-sized Spark EV will be targeted at US and Asian buyers and is expected to help GM meet California's Zero-Emission Vehicle (ZEV) mandate. It also reinforces a commitment to plug-in cars that GM has repeated over the last several years. "We're taking what we've learned in the EV1 and the Volt and using it in the Spark," GM spokeswoman Annalisa Bluhm told Design News prior to the rollout at the Los Angeles Auto Show. Bluhm added that 40 percent of the components in the Spark's motor are used in the Volt motor and much of the Spark's battery technology builds on lessons learned from the EV1 and Volt. The new five-door electric car will employ a 20-kWh lithium-ion battery from A123 Systems Inc. that will give the Spark "one of the best EV battery ranges in its segment," GM said. With its 130-hp permanent magnet motor, it will go from zero-to-60-mph in eight seconds and will be the first vehicle to employ the new DC fast-charging standard from the Society of Automotive Engineers (SAE), which will enable it to reach an 80 percent battery charge in 20 minutes. Inside, the vehicle will employ two high-resolution, seven-inch, color LCD screens; a MyLink radio for infotainment; and apps for navigation and global Internet radio. The vehicle's 20-kWh battery is slightly larger than the Chevy Volt's 16-kWh battery and smaller than the Nissan Leaf 's 24-kWh version. GM did not reveal the car's allelectric range, saying that it is awaiting EPA estimates. Design News | jaNuary 2013 | www.d esign n ews.com –32–
