It's not that easy being green, least of all if you're a builder of exotic, high performance supercars or uberluxury sedans. Recently however, there has been a move towards improving fuel economy and reducing emissions by many of the world's biggest and most well known luxury and performance brands.
Take Ferrari's stop-start equipped California HELE or Mercedes-Benz's SLS AMG E-Cell concept, for instance. And there's more on the horizon, including the plug-in hybrid 918 Spyder from Porsche and BMW's Vision EfficientDynamics, the latter of which allegedly will offer M3 performance with a CO2 emissions rating of just 99 grams per kilometer.
And it's not just these four who are in it for the environmental crowd cred: other makers including Lotus, Audi, Lamborghini, Jaguar and Bentley are also looking to green up their model ranges.
