Compared to the manual-stirred 911 Carrera, the new Corvette has two mpg fewer around town and two more in highway driving, for a combined rating of 21 miles per gallon of premium fuel to the 911's 22 mpg. Of course the 911 starts out roughly $30,000 more than the new Vette and escalates quickly into a $100,000 car; according to the FuelEconomy.Gov website, the annual difference in fuel costs between the two is about $100.
Aside from the Porsche 911, no other comparable sports car comes close to the Vette's efficiency score; the Audi R8 gets a thirsty 14 mpg combined, while the Jaguar F-Type V8 S pulls 18 mpg. Credit for the Vette's efficiency goes to a few old tricks — including the maligned skip-shift feature that forces a jump from first to fourth gear in some acceleration — and several new technologies, such as direct injection, an "eco" driving mode and a cylinder shut-off system that leaves only four of the 6.2-liter V-8's cylinders running at highway speeds.
The U.S. Environmental Protection Agency didn't release the mileage figure for the six-speed automatic Vette, but given that the new manual model boasts a 23 percent efficiency improvement over the previous generation, there's only one direction the numbers should trend.
