Some of the redundant features include things like windshield wipers and high-powered audio systems. The older systems will be eliminated later, probably in the second generation of the Volt, after engineers have had time to rework them for the new world of electric propulsion. "Because we're going as fast as we're going to get this to market, some of the systems will have to be redundant," GM spokesman Dee Allen revealed to Canwest News.
In ordinary petrol and diesel cars, these electrical systems draw power directly from the engine. This power can be enormous, especially in the case of modern stereo systems, which in a car with an electrical propulsion system will mean a greatly reduced range per charge whenever the devices are in use.
"What we've ended up doing is having to re-engineer things most people take for granted," Allen said. The engineers have no doubt they can rework the electrical utilities of the car to meet modern demands, but not in the timeframe given to them by GM vice chairman Bob Lutz to bring Volt to market.”
