DETROIT– At 33 mpg highway, four-cylinder, non-hybrid versions of the 2009 Chevrolet Malibu and Saturn Aura mid-size sedans equipped with six-speed transmissions carry a higher EPA highway fuel economy.

"Fuel economy is top-of-mind for many of our customers, and we're providing great-looking, well-equipped, and fuel-efficient choices across our lineup — from subcompacts to crossovers to full-size pickups and SUVs," said Mark LaNeve, GM North America vice president, vehicle sales, service, and marketing. "We are using our technology leadership to squeeze more miles out of a gallon of gas, and we are investing our global resources to develop advanced technologies to help us diversify the energy sources for our future transportation needs."

In all, GM delivers 18 2009 models — including three hybrids — that achieve EPA-estimated 30 miles per gallon or more on the highway, more than any other automaker. Chevrolet, GM's largest brand, leads with eight — including the popular Malibu mid-size sedan — followed by Pontiac and Saturn with five each.
