GM adds fuel economy package for large trucks

General Motors is tweaking some of its full-size pickups and sport-utility vehicles, using lighter materials and sleeker aerodynamics in an effort to bolster their fuel economy.
The Chevrolet Silverado and Tahoe and the GMC Sierra and Yukon are being packaged with the refinements. They get special badging, XFE, which stands for Xtra Fuel Economy. The upgrades allow the vehicles to eek out an extra mile per gallon in fuel ratings--they now get 15 mpg in the city and 21 mpg on the highway.
The XFE package also includes six-speed automatic transmissions, which are an optional upgrade on other models from the four-speed gearboxes. The transmission change increases towing capacity to 7,000 pounds in the Silverado and Sierra pickups, though the SUVs' tow ratings remain unchanged.
Other improvements include a lowered suspension, specially-tuned chassis, low-rolling-resistance tires and lighter-weight aluminum wheels.
Production of the vehicles, which are 2009 models, begins this fall.

GM is resorting to quick fixes, rather than substantial improvements for fuel economy. Low rolling resistance tires are a quick fix to slightly improve fuel economy on any vehicle, but low rolling resistance tires also offer less grip and performance than regular tires. On a large truck or SUV, low rolling resistance tires are dangerous, especially in bad weather.

I wonder how much $$ GM wasted developing this "XFE" angle?
I heard the Cobalt XFE is out there as well...but with a more significiant MPG improvement.

The Cobalt XFE does offer impressive fuel economy.
As for the XFE full sized trucks and SUVs... I dunno. If it's a free option, like an either you get it or you don't type thing then it's a nice thought. I mean a 5-7% increase in fuel economy is nothing to sneeze at.
I mean for the typical driver that'd save over 60 gallons of fuel per year.
Again, if it's a free option then in 4 years time you'd save $1000 in fuel costs.
To anyone complaining about GM not doing enough... stop being so narrow minded. No auto manufacturer can react in just a few months' time with anything significant. This tweaked XFE package is about as much as any auto manufacturer would be able to do. GM has shifted all sorts of production and design resources accordingly based on this trend, but expecting anything more out of them in reactionary terms only means you don't understand how long things take from planning to implementation in the auto industry as a whole.
Should GM have had more foresite coming into this 'era'? Absolutely. Huge mistake there on their part. But if you're keeping score from 'gas price boom' on forward, GM is making all the right moves.

I dunno, the $40,000+ (Lutz has been quoted saying $48K!!!) 40 mile range VOLT seems a bit over-priced to be a success, but we'll see.

I expect it'll also be the first car in a very long time that will actually drop in price after its initial release and after the price of batteries goes down.
Cars like the volt are the future IMO... the Volt may just come in 3-4 years ahead of its time.

At 40k it'll be hard to make a real cost case for it but it may still be popular as a trend item... we'll see. Either way it'll be a nice halo piece for GM to be perceived as a more green company than it currently is.

btw - weren't you thinking of a Cobalt purchase a while back?

If GM would take the millions they are spending on advertising during the Olympics and use it to invest in design and advanced material, it would be a nice start. :X

Lol, I bet if Toyota came up with this, the usual suspects would be lauding it as another example of how great Toyota is, how much Toyota cares about the environment, yada yada yada.
FYI, a 1 mpg improvement in a 17 mpg vehicle is a 6% efficiency gain, which is pretty significant.
Of course, when Lexus does something to improve fuel economy by 6% (i.e., going from a 6 speed to an 8 speed), people say it's the greatest thing.

I think its good but to advertise it as a "package"?
Oh fyi, Toyota/Lexus are already some of best fuel economy cars in any class.
