Modified Caterham Seven Hits 131 mpg in Eco Marathon

Think the Caterham Seven roadster was only good for track days and carving up country lanes? You're absolutely correct, but the company found out if you also slap on a bunch of aerodynamic gear and skinny tires, you can get one to hit 131 miles per gallon (though, to be fair, that's probably those bloated UK royal gallons). Still, it's a matter of bragging rights for the roadstermaker, which showed off its eco-minded prototype at the recent Shell Eco-Marathon at Rockingham. The concept was based on Caterham's outgoing 1.6-liter Rover K Series engine (the new models have Ford engines), with a carbon-fiber aero kit from Axon Automotive. A company rep also said they used "careful driving" to blast through the original target of 100 mpg.
