Bentley Backs Away From Biofuel Bomber, At Least For Awhile
We've always been more than a little skeptical about Bentley's biofuel claims for its 2010 Continental Supersports hot rod. We think it's very, very unlikely that owners of a $267,000 near-supercar will seek out one of the few hundred E85 ethanol pumps in the country to cut their carbon emissions...John Voelcker
