It’s measured in gallons per mile.
Rocket fuel?
I don’t know about the Demon, but here are the numbers for the 650 Hp Corvette Z06 from two years ago:
The top-of-the-line 2015 Chevrolet Corvette Z06 performance coupe with an eight-speed automatic transmission delivers 13 mpg in city driving and 23 mpg on the highway, according to newly released fuel economy numbers by the EPA.
Consumers have been waiting for these numbers, since this is the first Corvette Z06 to offer a supercharged engine. GM says the 2015 Corvette Z06 is the most powerful production car ever from General Motors and one of the most powerful production cars available in the U.S.
The Corvette Z06 is equipped with a supercharged 6.2-liter V8 engine that churns out 650 horsepower and 650 pound-feet of torque.
