General Motors announced today that it would offer an 8-year, 100,000-mile warranty on the battery pack, the charger, and the Voltec electric drive components of its upcoming 2011 Chevrolet Volt electric car.

The announcement sets to rest potential worries that Volt owners might be stuck having to replace an expensive, high-voltage battery pack costing thousands of dollars just a few years down the road.

The warranty matches the length of time that all components affecting the car's emissions must be free of owner maintenance, as per NHTSA regulations. It rises to 10 years or 150,000 miles in the several states that have adopted California's stricter emissions limits.

While GM has not announced the replacement cost of the 2011 Volt's 16-kilowatt-hour lithium-ion battery pack, the 300-pound, T-shaped pack is widely expected to cost GM several thousand dollars to build.

Replacement parts costs are usually twice the manufacturer's cost, or more. The rest of the 2011 Volt carries GM's usual warranties of 5 years/100,000 miles on other powertrain elements (essentially the engine) and 3 years/36,000 miles on the rest of the vehicle.

The announcement came during a media event at the Brownstown Township plant where GM assembles the battery packs, using cells manufactured in South Korea by LG Chem.  Manufacturing of pre-production Volts in Detroit's Hamtramck plant began on March 31.

The plug-in 2011 Chevrolet Volt, as GM hopes you know by now, travels up to 40 miles on battery power alone. After that, its 1.4-liter gasoline engine switches on to run a generator that provides electric power to the motor that drives the front wheels.

That "range-extending" engine differentiates the Chevy Volt from the other electric vehicle launching for 2011, the Nissan Leaf. The pure battery electric Leaf has an electric range of up to 100 miles, but no gasoline range extender.

To highlight the Volt's unlimited travel and lack of range anxiety, GM drove a 2011 Volt from Austin, Texas, to New York City over the Fourth of July weekend. The so-called "Freedom Drive" covered 1,776 miles on a mix of grid power and engine-generated electricity.

GM has not yet priced the 2011 Volt, though now-retired GM executive Bob Lutz said two years ago that he expected the price to be around $40,000. Early Volt buyers are eligible for a $7,500 Federal tax credit and various state incentives as well.

  1. Went to the Cherry festival in Traverse City MI on the 3rd of july. Saw 2 Volts parked on a busy sidestreet off union street. No manufacturers plates just id's on the bumpers, one had a baby seat in it and when i stopped and got out people passing me asked what I was doing and a crowd gathered to look the car over. Bigger then pictures suggest, but almost blends in with the other cars. VERY cool
