LIVE LONG enough, you see everything. Such were my thoughts as I studied the news reports that GM plans to build an electric Cadillac patterned on the same twist of hybrid technology used in the Chevy Volt.
The Chevy Volt went on sale last December, and it’s poised to be available in increasing numbers soon. It’s an interesting blend of an electric car and a gasoline one. You plug in the Volt to charge its battery, and at first the car then runs as a purely electric vehicle. You can get through a lot of your daily driving entirely on that electric charge — from 25 to 50 miles — based on the lithium-ion battery.
