General Motors said Tuesday its Chevrolet Volt electric car could get 230 miles per gallon in city driving, making it the first American vehicle to achieve triple-digit fuel economy if that figure is confirmed by federal regulators. A glance:
How does it work? The Volt is powered by an electric motor and a battery pack with a 40-mile range. After that, an internal combustion engine kicks in to generate electricity for a total range of 300 miles.
How will it be recharged? A standard home outlet will do the job. Charging the battery pack takes eight hours with a 120-volt outlet, three hours with a 240-volt outlet.
When will it be available? Late 2010. But two critical areas — battery life and the electronic switching between battery and engine power — still are being refined.
How much will it cost? About $40,000. But the price is expected to drop, and up to $7,500 in tax credits are available.
