Why is the Chevy Volt only getting 40 miles on charge?

I have seen other startup companies producing cars that can go 75 mph for 100, or 200 miles. Maybe Chevy doesn't really want an electric car to be successful? Remember the EV-1? In the 90's that car was getting 60 to 100 miles per charge.

IS this why they are called PROTOTYPES??
