Oshawa, Ontario (Tuesday, Nov 11, 2014) – Thanks to a further of an all-new 8-speed involuntary transmission, a updated 2015 GMC Yukon Denali and Yukon XL Denali models now lead several competitors in horsepower, torque and highway fuel expenditure ratings.

Both a Yukon Denali and Yukon XL Denali now span their 6.2-liter EcoTec3 V-8 engines with a new Hydra-Matic 8L90 eight-speed involuntary transmission,   designed to be some-more fuel-efficient than a Denali’s prior six-speed automatic. Highway fuel expenditure ratings for Yukon Denali and Yukon XL Denali models softened to 11.1 L/100km with a eight-speed automatic, while a city rating has softened to 15.9 L/100km.

Within a segment, a Yukon Denali continues to broach unequaled energy and efficiency. Denali’s 6.2L EcoTec3 V8 delivers a segment-leading 420 hp and segment-leading 460 lb-ft of torque with highway fuel potency equal to or improved than many 6- or 8-cylinder engines in rival makes.


Compared to a Yukon Denali’s prior six-speed transmission, a new 8L90 delivery offers smaller stairs between gears, permitting a engine to well precedence a rise energy bands. The wider gearing widespread also allows a use of a reduce 3.23:1 back spindle ratio, that reduces engine speeds and fuel consumption, generally during highway cruising.

Comfort and capability are not compromised for fuel efficiency. Not usually is a 8L90 delivery able of doing some-more torque than a six-speed delivery it replaces, though a change controls and solenoids are some-more manageable and yield quicker change times. A new torque converter also delivers smoother opening during low speeds, generally when carrying complicated loads or pulling trailers. Tow ratings – adult to 3,674 kg (8,100 pounds) for a Yukon Denali and 3,583 kg (7,900 pounds) for a Yukon XL Denali – are unblushing by a further of a eight-speed transmission.

The 2015 Yukon Denali and Yukon XL Denali continue to mix singular pattern elements with upscale amenities, including reward interior materials.  Convenience and connectivity improvements include:

  • A new hands-free energy liftgate, that can be non-stop and sealed by simply flitting a feet underneath a back bumper
  • A wireless charging aspect for WPC (Qi) or PMA (Powermat) concordant mobile inclination integrated into a pattern of a core console lid. A list of concordant inclination is located during
  • OnStar with 4G LTE, that provides in-car information connectivity and a Wi-Fi hotspot able of joining adult to 7 inclination during one time
  • An extended GMC Intellilink system, that provides incoming ‘Text Message Alerts’ when interconnected to a concordant Bluetooth phone

The updated 2015 Yukon Denali and Yukon XL Denali models are labelled from $74,600 and $77,650 respectively (plus a end assign of $1,695), and are now accessible during dealers.

The code is elaborating to offer some-more fuel-efficient trucks and crossovers, including a Terrain tiny SUV and Acadia crossover. GMC’s highest-volume vehicle, a Sierra pickup, is a many absolute light avocation pickup on a market, and a initial full-size pickup to accept a top probable five-star Overall Vehicle Score for reserve given a U.S. National Highway Traffic Safety Administration altered a New Car Assessment Program for a 2011 indication year.
