You'll get a charge out of this.
DETROIT – General Motors Co. is guaranteeing the battery in its Chevrolet Volt electric car for eight years or 100,000 miles in an effort to inspire confidence in the new technology. The guarantee is better than warranties on GM's conventional car engines and transmissions, which are five years or 100,000 miles. The rechargeable Volt is due in showrooms this November. The vehicle can travel 40 miles on battery power before a small gasoline engine takes over to generate power so the car can go longer distances. The Volt is expected to be priced around $35,000 but will probably cost less after federal tax credits. Other automakers are rolling out electric cars. Shortly after the Volt goes on sale, Nissan Motor Co. will begin selling the Leaf, which the company said will get up to 100 miles on a single charge.
