1. Heart of a Sports Car
The cornerstone of the 2015 Yukon Denali is a 6.2-liter V8 making a hearty 420 hp and 460 lb-ft. of torque. That is an increase of 65 hp and 77 lb-ft of torque over the regular Yukon’s 5.3-liter V8. In a truck weighing 5,784 lbs., this may not sound like a big power increase, but on the road it is immediately noticeable. With a soundtrack inspired by the Chevrolet Corvette, the Denali roars away from a dead stop compared to the lackadaisical approach taken by the regular Yukon.
The best part of the larger engine, however, may be the fuel economy penalty or, more accurately, the lack thereof. Officially rated at 15 MPG in the city and 21 MPG on the highway, the two-wheel drive Yukon Denali only sacrifices a single mile per gallon compared to the down-market version with the 5.3-liter engine.
