Plug-in electric vehicles were hot at this week's NAIAS, with several start-ups entering the fray to compete with the big boys. Besides the Tesla that's been getting a lot of press lately, is the new Karma Sunset concept from Fisker.

Started by Henrik Fisker, an auto designer for more than 20 years, responsible for the BMW Z8, the Z07 concept, and the Aston Martin DB9, Fisker Automotive manufactures "premium green automobiles". And with price tags closing in on six figures, they're pretty premium.

The Sunset is powered by their exclusive Q-DRIVE that'll get you 50 miles on a single charge and up to 403 horsepower from the twin electric motors. (Like other EVs, run the battery down and the car becomes a traditional hybrid, running off gas and electric until you can recharge.)

While the Karma sedan has solar panels in the roof, the Sunset has a power retractable roof that lets the sun shine in. Makes it a helluva lot easier, and more stylish, to be green.
