The 6.0 liter is good for 332 horsepower at 5,100 rpm and 367 lb-ft of torque at 4,100 rpm. Fuel economy numbers for the two-wheel drive SUV are 21 mpg in the city and 22 mpg on the highway, while the 4WD version manages 20 in either cycle, as estimated by the EPA. This compares favorably to an equivalent 2WD Tahoe with a gas engine only, which is rated at 14 mpg city and 20 mpg highway. Towing capability is rated at a maximum of 6,200 lbs for the 2WD and 6,000 lbs for the 4WD model.
