Even the purveyor of the gas hog six-and-three-quarters-liter V-8 is now joining the green movement. The Bentley Continental Supersports you see here is powered by E85 (a blend of 85 percent ethanol, 15 percent gasoline), thus Bentley Motors' one and only claim to eco-friendliness thus far.
Here are the specs:
Alas, the folks at Crewe didn't get the memo that ethanol is on its way out as the biofuel - or eco-technology - of choice. At least in the U.S., cries of food chain disruption and poor energy density have made it very unpopular next to gasoline/electric hybrids and even fuel-sipping clean diesels.
But ethanol can be produced without using fresh ears of corn. Scientists and clean energy companies are springing up that can turn garbage - yes, nasty old municipal waste - into cellulosic ethanol. While nascent, these new technologies are promising; perhaps you will one day be able to waft your 612-hp W12 Bentley Continental Supersports to the Oscars and back with neither guilt towards nor hatred from the Hollywood Prius-driving set.
