Asked by Tower Mar 15, 2008 at 05:25 PM about the 2008 GMC Yukon XL SLT-2 3/4 Ton 4WD

Question type: Shopping & Pricing

3/4 ton has new engine and 6 speed transmission and weighs about 600 lbs than the 1/2 ton version.  Dealer tells me the 3/4 has heavier frame, bigger axels, etc.  Trying to decide between the two as I tow a bigger boat.  Is there a ride tradeoff with the 3/4 ton?

I would check out www.fueleconomy.gov, they will have the gas mileage ratings. Everything I have read indicates that the trade-off in ride is typical between a 1/2 ton and 3/4 ton vehicle -- the 3/4 ton will not ride as well unless it is under a load, since it is designed to ride correctly with the load being hauled, and will be less comfortable without a load.

the mileage won't be as different as you think, because the 3/4 ton doesn't have to work as hard to tow it. 16-18mpg empty on the 3/4- 20-21 on the 1/2 ton, but that will drop alot towing because the 1/2 ton won't shut down the 4 cylinders the way it does when you are just driving (to conserve fuel) so they will be very similar mileage when towing.
