According to General Motors, the 2013 Chevrolet Spark EV will be equipped with an electric motor that puts out a whopping (for the car's size class, that is) 114 peak horsepower (85 kilowatts). That motor will be built at a plant in Maryland, making this motor the first of its kind assembled domestically.

Sustained power from the motor will reportedly come in at 75 horses, which is rather impressively about two-thirds of its available peak power.

For reference, the standard-fare, gasoline-powered Chevy Spark uses a 1.2-liter four cylinder that puts out a comparatively paltry 83 horsepower. A more apples-to-apples comparison: The electric 2012 Mitsubishi i features a 66-horsepower motor.

Of course, it's instant torque that is the most noteworthy aspect of an electric vehicle's performance. In any case, here's hoping GM's first fully electric vehicle since the old EV1 feels as sprightly as its high-power motor suggests.

Chevrolet Showcases Spark EV Electric Motor
GM to be first automaker to domestically produce electric motors


2011-10-26

WIXOM, Mich. – From home appliances to children's toys, electric motors are all around us and have nearly a century of automotive use dating to Charles Kettering's invention of the electric starter first used in 1912. With the emergence of electric vehicles, electric motors also will play a bigger part in future vehicles.

"We've spent the past few years highlighting our in-house battery capability, which will play a significant role as one of our core competencies going forward," said Larry Nitz, GM executive director of Vehicle Electrification Engineering. "Electric motor development and manufacturing is another area of expertise we'll need as we expand vehicle electrification technologies to address the needs of our customers around the world."

Chevrolet is highlighting its expertise in electric motors at a pilot facility in Wixom, a Detroit suburb, in advance of beginning the domestic production of electric motors at GM's plant in White Marsh, Md., near Baltimore in late 2012. Specifically, equipment and processes to be used at White Marsh are being validated and tested in Wixom.

Conventionally powered vehicles on the road today have a variety of electric motors to power seats, windows, windshield washers and other functions. Electric motors are used in hybrid and electric vehicles to move the drive wheels to propel the vehicle. Electricity is stored in a battery and feeds power to the electric motor to drive the wheels.

GM is focused on the development of permanent magnet and induction motors for a variety of applications. During a recent tutorial at the Wixom facility, news media were given the opportunity to hand build portions of a permanent magnet motor, the exact 85 kW (114 hp) permanent magnet motor configuration that will be used in the recently announced Chevrolet Spark electric vehicle to debut in 2013.

The White Marsh facility will produce electric motors for the Spark and other future vehicles. Currently, GM uses electric motors as part of the propulsion system in nine vehicles including the Chevrolet Volt, Chevrolet Malibu Eco, Chevrolet Silverado Hybrid, Buick Lacrosse eAssist, Buick Regal eAssist, GMC Sierra Hybrid, GMC Yukon and Yukon Denali Hybrid, and Cadillac Escalade Hybrid.

Founded in Detroit in 1911, Chevrolet celebrates its centennial as a global automotive brand with annual sales of about 4.25 million vehicles in more than 120 countries. Chevrolet provides consumers with fuel-efficient, safe and reliable vehicles that deliver high quality, expressive design, spirited performance and value. The Chevrolet portfolio includes iconic performance cars such as Corvette and Camaro; dependable, long-lasting pickups and SUVs such as Silverado and Suburban; and award-winning passenger cars and crossovers such as Sonic, Cruze, Malibu, Equinox and Traverse. Chevrolet also offers "gas-friendly solutions including Cruze Eco and Volt. Cruze Eco offers 42 mpg highway while Volt offers 35 miles of electric, gasoline-free driving and an additional 344 miles of extended gasoline range, according to EPA estimates. Most new Chevrolet models offer OnStar safety, security and convenience technologies including OnStar Hands-Free Calling, Automatic Crash Response and Stolen Vehicle Slowdown.
