Today’s Nissan Leaf has a 100-mile driving range per charge. The Chevy Volt has a 350 miles driving range. However, this increased range is achieved through an onboard gasoline generator that can recharge the battery. The expectation is that the next leap in technology will bring solely electric cars with a 300-mile driving range between charges. Consumers will expect it to be price competitive with the operating cost of a 50-mile per gallon hybrid like the Toyota Prius. For driving enthusiasts it would also be cool if it could perform like a Porsche.
