The GMC Yukon gets updated powertrains, new fold-flat rear seats, and a trimmer new look for the 2015 model year, following a year after the truck brand's complete renovation of its Sierra 1500 pickup truck.
The new big SUVs are slated for showrooms first quarter next year as 2015 models. A 5.3-liter V-8 is standard in all but the Yukon Denali models, which get a 6.2-liter V-8 rated 420 horsepower and 460 pounds-feet of torque.
Direct-injection EcoTec3 engines contribute to that effort, as well. For now, Suburbans and Tahoes get a 5.3-liter V8 producing 355 hp and 383 lb-ft of torque. That's up 35 hp and 20 lb-ft over the 5.3-liter in the 2013 models of the trucks. The standard Yukon and Yukon XL get that same 5.3-liter, but step up to the Yukon Denali and you'll enjoy a 420-hp, 540-lb-ft 6.2-liter V8. All models share a six-speed automatic transmission.
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 interiors of the Chevy and GMC SUVs have been updated, as well. The prior Tahoe/Suburban and Yukon have never featured fold-flat third-row seats - just fold-and-flip seats – but all three now come standard with fold-flat second- and third-row seats, which can be equipped with an optional power-folding feature. Second-row passengers also get two inches more leg room. Multiple USB ports and power outlets are littered throughout their interiors, including one 110-volt, three-prong outlet. The Yukon also includes SD card slots.
