The 2015 GMC Yukon is all-new with greater capability, more refinement, increased connectivity and a new family of advanced EcoTec3 engines.
That EcoTec3 engine will deliver not just more horsepower and torque, but the segment’s best V-8 fuel economy. EPA estimates give it a 23 MPG highway rating for the standard 5.3L engines on 2WD variants. That’s a 10 percent improvement over prior models.
The 2015 GMC Yukon Denali comes with a larger 6.2L engine that’s the most powerful in the segment and boasts 420 horsepower and 460 lb-ft of torque. EPA ratings for the Denali are 15/21 city/highway for 2WD variants.
The 2015 GMC Yukon and Yukon XL have similar design and powertrains but the XL gets a 14″ longer wheelbase and an additional 20″ in overall length. This means more legroom for the third row and twice the cargo room behind that third-row seat.
All 2015 GMC Yukon models feature fold-flat second and third-row seats with available power folding, an available power rear liftgate with programmable height settings, a standard 8″ color touch screen radio with IntelliLink and available navigation, an 8″ customizable driver display with three themes and a heads-up display available on the Denali.
There are plenty of new safety features like a forward radar system and the segment’s only front seat center-mounted air bag designed to protect during far-side impact crashes, as well as forward collision alert, front park assist, lane departure warnings and GM’s Safety Alert Seat which vibrates to warn of a possible collision.
The exterior has been given an update to create a design that looks sleeker and increases the vehicle’s aerodynamics. There are bold, chrome-accented grilles with GMC’s signature C-shaped light-emitting diode motif in the front and rear. Projector beam headlamps are standard with the Denali getting high-intensity discharge headlamps.
Additional refinements to the vehicle’s design include inlaid doors that reduce wind noise, laminated windshield and front door glass to improve quietness, a standard rear spoiler on the liftgate with a hidden rear wiper and illuminated, power-retractable steps available on the Denali.
An enhanced chassis and suspension system includes a fully boxed frame made of 75% high-strength steel and shear-style body mounts for improved stiffness and a smoother ride. There’s also a wider rear track, wheels that are 1/2″ wider, new electric variable-assisted power steering and a new 9.5″ rear axle with an automatic locking rear differential.
There will be two engine variants with the 5.3L v-8 coming standard on the 2015 GMC Yukon and Yukon XL while the Denali gets a 6.2L. Both EcoTec3 engines feature direct injection, cylinder deactivation, continuously variable valve timing and an advanced combustion system. They’re mated to a Hydra-Matic 6L80 6-speed automatic transmission.
TFLcar was among the first to drive the new 2015 GMC Yukon and we’ll have a video review coming soon!
