Fuel Economy Of 2015 Chevrolet Tahoe, Suburban And GMC Yukon Fuel Economy Almost As Good As V6 Crossovers

General Motors has released EPA estimated fuel economy figures for the new range of full-size SUVs from Chevrolet and GMC.

The 2015 Chevrolet Tahoe and Suburban and GMC Yukon and Yukon XL get an EPA estimated 16 mpg in the city and 23 mpg on the highway in two-wheel drive modes when equipped with the standard 5.3 liter EcoTec3 V8 engine. This represents a 10 percent increase in highway mileage over the outgoing models and a 7 percent increase in city mileage. That 23 highway mark is just one figure under as the 24 mpg highway mark as GM’s V6-powered Lambda crossovers; being the Chevrolet Traverse, Buick Enclave and GMC Acadia. One figure under the city mileage, too. Considering the significant size and power of these new full-size SUVs makes it all the more impressive.

The 2015 GMC Yukon Denali and Denali XL are equipped with a 6.2 liter EcoTec3 V8 producing 420 horsepower and 460 lb-ft of torque, more than any other full-size SUV. Denali and Denali XL models return an EPA estimated 15 mpg in the city and 21 mpg on the highway in two-wheel drive modes.

  1. Not too bad, but not that great either. Despite all the fuel saving technology these SUVs are still considered too thirsty. Which is why a diesel and/or a hybrid model should become available.

    1. And the diesel comment. Ugh. yes, diesel is the answer. The truck will cost 5-6 thousand more and you will be buying gas that currently costs 80-90 cents more per gallon. Ever hear of return on investment? You won’t by buying a diesel suv.

      GM had a hybrid Tahoe. It doesn’t work that well for vehicles this large.

      1. I have a Yukon Denali Hybrid right now and I love it and I am disappointed that that technology won’t extend to the new models. I consistently am able to get 21mpg in all conditions and I’m afraid I won’t be able to match that with a new Denali. I bought my truck as a dealer demo so I saved about $12,000 off list so my investment in the hybrid over the regular is negligible.

  2. Jamel, buy a Toyota then. Oh wait, its comparable sized model, the Sequoia is rated at 13/17…. That’s 3 less in the city, 6 less on the highway. Nissans big suv gets 13/19…that’s only 3/4 less. Expedition, that’s the answer. Crap, 14/20.

    GM’s fullsize SUV’s don’t just beat the competition in efficiency, they DOMINATE. Could be better though…Double standards much?

  3. This is great news! I told you that 3.6L sucked (no pun intended, okay kind of)! I hope GM will downsize the 3.6L to 3.2 or 3.0 with 295HP/265FT-LBS along with VVT, SIDI and *iVVL and only put it in CUV’s for better tow ratings. I still think that they should make a hybrid 4.3L (VVT, SIDI, AFM and iVVL) with 335HP/310FT-LBS. The reason the current hybrid trucks do not work so well is that it packs a 6.0L under the hood. Should I say more?

  4. I think the 2015 chevy tahoe is a work of art I own a 2012 ltz and I love it like they say if you can afford the car you can afford the gas so I think mpg are pretty decent

  5. And there are people that say Ford and dodge do a better job at being fuel efficient!

    You don’t hear Ford talking about how fuel efficient there suv’s are!

    I wonder why that is?
