What's New for 2015:

- More powerful and fuel-efficient engines
- Claimed improvements in driving dynamics
- Modern infotainment and safety technologies

The 2015 GMC Yukon is redesigned, but remains a full-size, 8-passenger SUV designed for hauling and towing more weight than a crossover SUV can tackle. Two versions are available, with the long-wheelbase Yukon XL providing more passenger and cargo space than the standard Yukon.
Key competitors for the Yukon and Yukon XL include the Ford Expedition, Nissan Armada, and Toyota Sequoia, while the luxury-themed Yukon Denali goes up against the Infiniti QX80, Lexus GX, Lincoln Navigator, and Mercedes-Benz GL-Class.Models and Features
The 2015 GMC Yukon is offered in SLE, SLT, and Denali trim levels. Upgrading to the Yukon SLT adds leather seats, heated and ventilated front seats with memory for the driver's settings, heated second-row seats with a power release function, power-folding third-row seats, power-adjustable pedals, and a power rear liftgate. Additionally, the SLT includes a heated steering wheel, keyless entry with push-button start, auto-dimming rearview mirror, and power-folding exterior mirrors, as well as a Driver Alert package of safety systems including side blind-zone alert, lane-departure warning with lane-change alert, rear cross-traffic alert, forward-collision alert, and a Safety Alert Seat.
The Denali is set apart by a chrome honeycomb grille design, high-intensity discharge headlights, Magnetic Ride Control suspension, and 20-in. aluminum wheels. The Denali's exclusive 6.2-liter V-8 engine features heavy-duty cooling, high-capacity air cleaner, and a more powerful alternator, and this version of the Yukon also gets a standard integrated trailer brake controller. Active noise cancellation technology is also standard for the Yukon Denali, along with a premium surround-sound audio system, navigation system, 8-in. configurable information display in the gauge cluster, and more.Under the Hood
The Yukon SLE and SLT are equipped with a new 5.3-liter V-8 engine featuring direct fuel injection, variable valve timing, and Active Fuel Management cylinder deactivation in order to produce the most amount of power while consuming the least amount of fuel. This engine generates 355 horsepower and 383 lb.-ft. of torque, and can tow a maximum of 8,500 lbs. (8,300 lbs. for Yukon XL models).
The Yukon Denali is equipped with a more powerful 6.2-liter V-8 engine making 420 horsepower and 460 lb.-ft. of torque. GMC recommends premium fuel for this engine, but it will run on regular gas. The Denali's engine features the same direct fuel injection, variable valve timing, and Active Fuel Management systems as the base 5.3-liter V-8. The Denali model tows a maximum of 8,400 lbs. (8,100 lbs. for Yukon XL Denali models).
Both engines are paired with a 6-speed automatic transmission and rear-wheel drive. A 4-wheel-drive (4WD) system is optional. GMC also includes free scheduled maintenance for the first 2 years or 24,000 miles of ownership.
Additional highlights include standard hill-start assist, automatic grade braking, and a tow/haul mode for the transmission, as well as trailer sway control and DuraLife brake rotors that are designed to last twice as long as conventional designs.Fuel Economy
Fuel-economy ratings for the Yukon's standard 5.3-liter V-8 are 16 mpg in the city and 23 mpg on the highway with rear-wheel drive, and 16 mpg city/22 mpg highway for vehicles with 4WD. The ratings are the same whether measuring the Yukon or Yukon XL model.
Denali versions are not as fuel-efficient. In the Yukon Denali and the Yukon XL Denali, the 6.2-liter V-8 returns 15 mpg in the city and 21 mpg on the highway with rear-wheel drive. With 4WD, the Yukon Denali is rated to get 14 mpg city/21 mpg highway, while the Yukon XL Denali should return 14 mpg city/20 mpg highway.Safety and Technology
The 2015 Yukon is available with numerous new safety and technology enhancements. GMC installs the latest versions of its IntelliLink infotainment systems in the Yukon, including an 8-in. color touch-screen display with gesture- and voice-recognition capabilities. IntelliLink also provides Siri Eyes Free operation for users of certain iPhone smartphones, and a text-messaging system that can read incoming messages through the SUV's speakers. Navigation is optional with IntelliLink.
Additionally, GMC offers next-generation OnStar connectivity with the redesigned Yukon. Claimed to be 100 times faster than previous OnStar systems, the new 4G LTE technology includes a free 3-month/3-gigabyte data plan. After the initial trial period, Yukon owners must subscribe to service. OnStar's Directions and Connections service plan is free for the first 6 months of ownership, and includes a number of safety and convenience features.
In addition to OnStar, the new Yukon is offered with a number of safety-related technologies. Highlights include forward-collision alert, adaptive cruise control with autonomous Front Automatic Braking, a side blind-zone alert system, lane-departure warning and lane-change alert system, and a rear cross-traffic alert system. A Safety Alert Seat vibrates to help get the driver's attention when a threat to safety exists.
In crash tests conducted by the National Highway Traffic Safety Administration (NHTSA), the 2015 Yukon and Yukon XL models earn an overall rating of 4 stars (out of a possible 5 stars). In each individual crash test, the SUV receives a rating of 5 stars, but a 3-star rollover-resistance rating brings the overall average down to 4 stars.
