If there was a competition for poster boy for the excess consumption of gasoline, the GMC Yukon would surely be among the finalists. While the hybrid version of the Yukon 1500 may be rated at 20 miles per gallon in the city, the 2500 is rated at half that amount. Nevertheless, the Yukon Hybrid hasn’t found a huge number of buyers. The best solution for the Yukon would be a turbo-diesel engine, but General Motors hasn’t had the gumption to drop a Duramax between the fenders, for whatever reason. A properly geared diesel would likely outshine the Hybrid on the highway. Even better if it ran B20 domestic renewable biodiesel. Fingers crossed we see it soon …

I know some folks say, it’s too big, it uses too much gas
Some folks say it’s too old, and that it goes too fast
But my love is bigger than a Honda, it is bigger than a Subaru
