Silverado XFEIn response to high gas prices GM is coming out with a special pickup truck model that’s geared for better fuel economy.

To try and protect its market share in the full-size pickup segment, GM’s coming out with what it’s calling XFE models, which stands for extra fuel economy. The Chevy Silverado and GMC Sierra XFE models are two-wheel-drive-only, equipped with a 5.3-liter V8 that’s mated to a six-speed transmission and can also run on E85.

To improve aerodynamics GM engineers added a tonneau cover on the bed, extended the front air dam, lowered the suspension and revised the chassis tuning. To cut weight they added aluminum wheels and lower control arms.
Even so, all that only improved fuel economy by one mile per gallon, and it shows just how hard it is to tweak a truck to get better gas mileage.

    It’s interesting that it only has one mpg better gas mileage.

    Great GM tried this quick fix.

    Looks like GM will need to find a way to reduce gross weight.

  2. Richard Tait Says:

    GM apparently missed the Mythbusters episode where they proved that a plastic mesh tailgate was better for economy than a tonneau cover. Here’s a better idea, though. Why not drop the 3.6L direct injection V6 (302hp) and back it up with cylinder deactivation technology and the hybrid transmission in this truck for some serious economy figures? 302hp not enough for the grocery run to the corner shop? Drop a turbo in. GM, like all the other car companies are joking. All they are doing is making OPEC richer and richer.
