Full-size news this week in the world of truck-based SUVs: the new Tahoe , Suburban and GMC Yukons have all gone public with a bold revamp ahead of an on-sale date in early February. Remember this moment, because such drastic changes to these lovable family haulers only happen about once a decade.
Such a long model cycle makes sense once you live a few weeks in the life of one of these luxury trucks. For most of the Tahoe ’s and Sub’s out there, the key mantra really is Like a Rock. Just get the basics so right that buyers will forgive the shiny and nasty leathers, previous purple-power colored plastic interiors, and a thirst for fuel like a Nascar fan slamming morning beers in the infield.
The Yukon Denali and its siblings will soldier forward over almost any obstacle, tow any ski boat, and - usually - become part of the family identity itself after years of reliable service.
In a segment they once owned all to themselves, there are now far more premium entries to choose from than ever before. Bringing these buyers back into the fold is part of the GMC Yukon Denali’s mission: match or best the Mercedes-Benz GL and Range Rover not just on all-weather ability, but also on technology, performance and style.
Even a quick glimpse at the Yukon Denali’s glamour shots will give you a good idea of the refinements on the table for this generation of GM full-size models. The Yukon Denali gets the pick of all the best new tech, like third-gen magnetic shocks, blue-ray players and more USB ports than an Apple store.

GMC will unveil the Denali XT Concept at the Chicago Auto Show. It offers a 50-percent increase in combined fuel economy over comparable small pickup trucks when running on gasoline, and it incorporates a new, muscular form in a performance-styled, hybrid sport-utility truck (SUT).
The concept is powered by a 4.9L version of GM’s small-block V8 engine that features fuel-saving technologies such as direct-injection technology and Active Fuel Management. The V8 engine delivers 326 hp. It uses direct-injection technology to produce the power of a larger engine, but consumes less fuel and produces lower emissions.
The Denali XT’s two-mode hybrid system is partnered with the 4.9L engine and uses an electrically variable transmission to enhance fuel efficiency in city and highway driving. In city driving, all-electric propulsion is used at low speeds; on the highway, fixed-gear operation enables efficient performance even when towing a trailer.
