Chevrolet Volt to use innovative GPS system for fuel economy
There are some new innovate features on the new Chevy Volt. For instance, what seems to be a GPS system at first sight, actually can also tell the driver how far he is from home. This is especially helpful in an electric car that is usually charged at home. It is a plug-in electric computer which can calculate how much time the car can use the gas engine to charge the on-board battery pack, providing a real fuel economy.
