The Volt is an electric car for drivers who don't want to be limited by battery range. It usually allows you to drive gas-free for 35 miles, however the exact number depends on weather and driving style. In our testing, it ranged from 20 to 50 miles. When the battery is depleted, a backup gasoline engine kicks in to keep the electric motor running. This allows you to keep driving for up to 315 more miles before refueling. If you charge every night and your daily drive fits within the battery's range, you might never need to buy gasoline.
Running on electricity alone, the Volt cost about four cents per mile at national-average electric rates -- much less than required to fuel any gas-powered car. Actual cost will depend on your electric rates, which vary greatly from state to state. Driving on the highway also diminishes the battery's range. We got our longest electric-only drives on rural roads at around 45 mph. The Volt is amazingly inexpensive to run on short trips, but when the gas engine kicks in and trips reach around 70 miles, traditional hybrids catch up. That's partly because the gasoline engine requires premium fuel, which strikes us as out of step with what Volt buyers might expect.
In most cases, automotive warranties are based on the vehicle identification number (VIN), and the warranty will be valid regardless of ownership. The dealership can tell you exactly how much warranty is left.Read more about extended warranties
