You switch over to gas where you have about a 350 mile to 400 mile range. That's not an issue for the Volt. The real issue is total cost to own vs reliability. Right now the Leaf is out selling the Volt because it has a lower total cost but the Volt significantly out performs the leaf and has greater range. With the $7,500 tax rebate the total cost is fairly competative for someone who wants to go green. It really boils down to the reliability issue. Dropping a new motor or transmission in a Volt at 100,000 miles will cost you far more then dropping an engine in a Corrola at 100,000 miles. That and when you buy a Corolla you do so knowing that you're probably not going to have to drop a new engine or transmission in it at 100,000 miles. There's not enough history on the Volt (or the Leaf) to know if they have this level of reliability.
