1 General Motors GM Communications media.gm.com Date: April 29, 2008 New Chevy Cobalt XFE Delivers 'Xtra' Fuel Economy - Segment Best 36 MPG On The Highway DETROIT - Consumers looking to squeeze the most mileage from every gallon of gas will find much to appreciate with the new Chevy Cobalt XFE. It delivers a segment-best 36 mpg in highway driving, outdistancing competitors like the Honda Civic, Ford Focus and Toyota Corolla. The Cobalt XFE - for Xtra Fuel Economy - is on sale now and includes LS and 1LT coupe and sedan models with the manual transmission. It uses revised engine calibration, low rollingresistance tires, a new, 3.74:1 final drive ratio and other technologies to achieve an EPA-estimated mileage rating of 25 mpg in the city and 36 on the highway. That's an improvement of more than 9 percent over the previous highway mileage. "Cobalt has always been an efficient performer, but the changes with the new XFE elevate it to a leadership position that will appeal to customers who put fuel economy at the top of their new-car priority list," said Ed Peper, Chevrolet general manager. "Better still, the efficiency enhancements don't come at the price of the safety and convenience features that serve as the foundation of Cobalt's value story." The new, higher-efficiency Cobalts are identified at a glance with "XFE" badges on the trunk lid. Customers can also verify the model they're shopping is the higher-mileage model by checking for the "36 mpg" designation on the window sticker. Like all U.S.-market Cobalt models, XFE editions come standard with: Head curtain side-impact air bags Air conditioning XM Satellite Radio AM/FM radio with CD and MP3 playback Rear defogger Center console with two power outlets The Cobalt XFE engine is powered by a 2.2L Ecotec engine that delivers excellent performance in conjunction with the class-leading fuel economy. The Ecotec engine also features numerous longlife maintenance items that help reduce ownership costs. "Any way you look at it, the Cobalt XFE is a smart choice for those looking to maximize their carbuying dollar," said Peper. "It's well equipped, efficient and plenty of fun to drive." # # #
