The Karma GSe-6 is one of the more conscious luxury sedans on the market, providing you with a plug-in hybrid engine that gives you the freedom you need to save on gas and keep going just about anywhere you want, no holds barred. It provides an 80-mile range on the electric engine and 70 miles per gallon on the gas engine. That’s nothing to laugh at with 536 horsepower under the hood to keep you going. And you’re not just saving on gas; the car was built with environmentally stable materials as well to reduce your carbon footprint even further. You have all the power in the palms of your hands with its incredible speeding and stopping capabilities. The GSe-6 also comes with solar roof panels that you can use to help recharge the batteries.
