Remember earlier in the year when Chevy quietly added the 36-mpg XFE model to its Cobalt lineup? XFE stands for "Xtra Fuel Economy" (should we tell them they spelled "Extra" wrong?) and means these vehicles have been equipped with some easy fuel-saving technologies to eek out as many miles per gallon as possible. GM announced today that the Cobalt XFE will be joined by XFE versions of the Chevy Silverado, GMC Sierra, Chevy Tahoe and GMC Yukon for the 2009 model year.

The General already offers hybrid versions of its full-size SUVs, which are also joined by hybrid versions of its half-ton trucks for 2009, but the XFE models will continue to be powered by a flex-fuel version of the company's 5.3L gasser V8. It produces 320 hp/340lb-ft in the Tahoe and Yukon, and 315 hp/338 lb-ft in the Tahoe and Yukon. All are rear-wheel-drive only and mated to GM's 6L80 six-speed auto with a fuel-saving 3.08 ratio rear axle. In order to maximize fuel economy, all four of these new XFE models get low rolling resistance tires, aluminum wheels, an aluminum spare wheel, aluminum lower control arms and a lowered suspension with revised tuning. In addition, the Silverado and Sierra also get a new front lower air dam and soft tonneau cover that improve their aerodynamics.

What does it all add up to? 1 mpg. All four standard vehicles were rated at 14 mpg city/20 mpg highway, while their XFE counterparts bump those numbers to 15 city/21 highway. The gains are certainly minimal and we're not sure yet what sort of price premium XFE models will demand, but we give GM credit for at least reacting to the current shift in consumer tastes so quickly. We would have preferred, however, that it had just made these fuel-saving changes standard equipment rather than a separate model.
