How to Get Infinity MPG: Fisker’s Eco-Chic Karma vs Chevy Volt

Looking for a sweet ride that can get you infinity miles per gallon? Check out the Eco-Chic Fisker Karma, a luxury sports sedan capable of 50 miles of emissions free-driving on one overnight charge.

This sexy-looking sports car, which I stumbled upon at the Detroit Auto Show earlier this week, uses the same kind of technology as the lusted-after Chevy Volt. Both cars use a purely electric drive train for the first 40-50 miles of driving, then switch to a small gasoline engine that recharges the lithium ion battery pack for longer drives. This means that if you drive less than 50 miles per day, you’ll only need to refill the tank once per year.
