The electric GM Chevy Volt is excepted to get a 230 mpg rating by the government when it goes on sale toward the end of 2010 according to General Motors.
"Having a car that gets triple-digit fuel economy can and will be a game changer for us," said GM CEO Fritz Henderson.
Figuring out the fuel economy of the Volt has been somewhat tricky since the car can drive up to about 40 miles using electricity only which means that some drivers would never use the car's gas engine.
After 40 miles the Volt's engine turns on to charge up the battery, but the Volt can also be recharged using a wall socket at work or at home.
The 230 mpg EPA rating for the Volt is currently based on the government city driving, Henderson said but he added that he believes the car's combined city and highway rating will be over 100 mpg.
