The ultra-rich among us — the few there are — who typically opt for sharp-looking gas guzzlers now have a greener option with the 2012 Fisker Karma, according to Cars.com Executive Editor Joe Wiesenfelder. The Karma works similarly to the Chevrolet Volt: It’s a series plug-in hybrid that can go 32 miles on all-electric power, according to the EPA. It’s pretty fast, and it has the stunning and exotic looks that a Bentley, Ferrari or Lamborghini owner typically looks for, says Wiesenfelder. Still, gas mileage, cabin controls and trunk space could be better.
