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.
