Did I hear that right? A Chevy Volt radio ad this morning concluded with a line like performance capabilities subject to change or may vary. I think it was the former. Should I be surprised given the GM’s rush to get this electric car into production by late 2010? That’s how fluid the battery situation is. The ad touts that you might seldom buy gasoline if you travel 40 miles or less day. Are people going to shell out big bucks for a car whose capabilities are subject to change? That said, I can appreciate GM’s candor. With the economy the way it is, it seems everything is subject to change by the hour.
