All-new exterior and interior designs advance GMC’s professional grade credentials with elements designed to be beautiful and functional. The exteriors are sleeker and more aerodynamic, enhancing efficiency on the highway and contributing to the new Yukon’s quiet ride.

Bold styling cues include highly detailed, chrome-accented grilles matched with GMC’s signature C-shaped light-emitting diode lighting motif, front and rear. Projector-beam headlamps are standard on Yukon and Yukon XL. The distinctive Denali models are instantly identifiable by their signature chrome grille and unique exterior appointments, including exclusive high-intensity discharge headlamps.

Additional exterior features include:

  • New inlaid doors fit into the body side openings instead of over the top of the body, significantly reducing wind noise and contributing to improved aerodynamics

Examples include soft-touch instrument panel, console and door panel materials with French seam stitching and purposeful use of ambient lighting in functional areas, including first- and second-row foot wells and the center console. All models have a standard Bose sound system, seats with dual-firmness foam and an ambient air vent designed to enhance comfort for front-seat passengers.

Denali models feature active noise cancelation technology to make the interior quieter.

There are more storage options in the new Yukon lineup, including a compartmentalized center console large enough to store a laptop or iPad and has provisions for hanging file folders and other organizational features, especially for customers whose vehicle also serves as a rolling office.

More capable, more comfortable

The 2015 Yukon lineup delivers greater capability and greater refinement through new and enhanced chassis and suspension systems. A fully boxed frame – composed of more than 75 percent high-strength steel – supports a quiet and controlled ride. New shear-style body mounts attached to the frame significantly improve stiffness and contribute to the Yukon’s smooth ride.

Compared with previous models, the driving experience of the new SUVs is further enhanced with:

  • Denali models include third-generation magnetic ride control, a real-time damping system that delivers more precise body motion control by “reading” the road every millisecond and changing damping in just five milliseconds.

Advanced engine technology

The all-new Yukon family is more powerful and efficient than before, thanks to the new EcoTec3 engine family, which debuted earlier this year in the all-new 2014 Sierra. A 5.3L V-8 is standard in Yukon and Yukon XL models and an exclusive 6.2L engine is standard in Denali models, delivering the segment’s best horsepower and torque – SAE-certified 420 horsepower (313 kW) and 460 lb-ft of torque (623 Nm).

The EcoTec3 engines feature state-of-the-art technologies, including direct injection, cylinder deactivation, continuously variable valve timing and an advanced combustion system, designed to make the most of power, torque and efficiency across a broad range of operating conditions. More precisely controlled combustion enables the new engines to run with a higher compression ratio, which delivers greater power and efficiency.

Hydraulic engine mounts, electronic throttle control, adaptive exhaust systems, improved aerodynamics and other technologies help the engines operate in four-cylinder mode for longer periods of time with Active Fuel Management, further increasing efficiency.

Both engines are matched with the Hydra-Matic 6L80 six-speed automatic transmission.

Manufacturing and factory support

The new Yukon family is built at GM’s Arlington, Texas assembly plant, and has begun arriving in dealerships.   

GMC’s ProGrade protection program, for two years/24,000 miles (whichever comes first) of scheduled maintenance, is standard and covers four services of an oil change, tire rotation and 27-point inspection. It complements the three-year/36,000-mile (whichever comes first) bumper-to-bumper limited vehicle warranty and five-year/100,000-mile (whichever comes first) powertrain limited warranty for peace of mind.

A standard OnStar Basic Plan is free for five years and includes OnStar Vehicle Diagnostics, Dealer Maintenance Notification and RemoteLink Key Fob Services, which allows owners to lock and unlock their vehicle, flash the lights and honk the horn, and even remotely start the engine (on equipped models) using the RemoteLink smartphone app. Additional OnStar services and data plans are available with a paid subscription.
