Changes for the 2015 GMC Yukon:
GMC has redesigned the Yukon for 2015, installing more powerful and fuel-efficient engines, improving the way the full-size, 8-passenger SUV drives, adding new infotainment and safety features, upgrading practicality levels, and more. What’s the only drawback to the new design? Cargo capacity actually shrinks because the third-row seat can no longer be removed from the vehicle.
GMC sells the 2015 Yukon in standard and extended-length Yukon XL models, and in SLE, upscale SLT, and luxurious Denali trim levels. Yukon XL models have 14 extra inches of wheelbase and 20 extra inches of length.
Engines and Transmissions:
For 2015, the Yukon models benefit from more powerful and efficient engines with claimed 10-percent improvement in fuel economy.
The SLE and SLT models have a new 5.3-liter V-8 making 355 horsepower while Denali models get a 420-horsepower, 6.2-liter V-8 that runs best on premium unleaded. Both engines include Active Fuel Management cylinder deactivation technology, and each is paired to a 6-speed automatic transmission that powers the rear or all four wheels.
GMC includes free scheduled maintenance for the first two years or 24,000 miles of ownership. Yukons also feature new DuraLife brakes that are designed to last twice as long, as well as a transmission Tow/Haul mode, hill start assist, automatic grade braking, trailer sway control, and electric steering,
Fuel Economy Ratings:
Choose the SLE or SLT trim level, and your new Yukon will get 18 mpg whether or not it also has 4WD. The Denali’s larger, more powerful engine returns 17 mpg with rear-wheel drive and 16 mpg with 4WD.
The NHTSA gives the 2015 Yukon models a 4-star overall rating, but the downgrade from a 5-star rating is solely due to the SUV’s 3-star rollover rating. In crash-test evaluations, the Yukon earns 5-star ratings across the board. Plus, the base curb weight is 5,466 lbs., double that of a typical compact car.
The Insurance Institute for Highway Safety (IIHS) had not assessed the Yukon as this summary was written.
Every 2015 Yukon includes new OnStar 4G LTE connectivity, which provides mobile Wi-Fi access for the first three months or 3GB of data use. Buyers get six months of OnStar Directions and Connections service, including Automatic Crash Response and other useful features.
The latest version of IntelliLink technology is also standard, now featuring text-messaging support, which reads incoming texts through the vehicle’s audio system, and Siri Eyes Free technology. Gesture and natural voice recognition is also standard, along with an 8-inch color touchscreen infotainment system. Navigation is an option, and the Yukon XL can be fitted with a new Blu-Ray DVD dual-screen rear entertainment system.
Available safety features include a front center airbag, Side Blind Zone Alert, Lane Change Alert, Rear Cross Traffic Alert, Forward Collision Alert, Lane Departure Warning, and Crash Imminent Braking. Adaptive cruise control is also available.
