GM Reveals Redesigned 2015 Chevrolet Tahoe / Suburban and GMC Yukon
Posted on September 12, 2013
GM has revealed pictures of the totally redesigned 2015 Chevrolet Tahoe / Suburban and GMC Yukon. These are some of the last remaining body-on-frame SUVs that can tow heavy loads, making this important news to many of our readers. Production of the 2015 models begins in the first quarter of 2014.

The new-generation SUVs are based on the structure of the recently released 2014 Chevrolet Silverado and GMC Sierra full-size pickup trucks and share powertrains with the pickups. Overall size and weight are roughly in line with the previous models.
The styling of GM’s 2015 SUVs is attractive but conservative, and according to GM engineers, subtle details greatly improve the vehicles’ aerodynamics. We find the new 2015 Tahoe and Yukon attractive, but styling is really an afterthought when buying one of these haulers.
The totally new interior of the 2015 Chevrolet Tahoe and Suburban and 2015 GMC Yukon appears to be vastly improved versus the prior generation. It features richer materials and less utilitarian styling. The new interior features large touchscreen infotainment systems that also control access to the many new safety systems, including blind-spot warning, forward collision alert, lane-departure warning and active cruise control. Also, in a major improvement in terms of usability, the third-row seat no longer needs to be removed to fee up additional cargo space. Instead, the 2015 models include a newly retractable third-row seat that can fold down to create a fully flat (although somewhat sloping) cargo deck from behind the front seats to the rear hatch. That being said, total cargo space shrinks considerably versus the previous generation Tahoe / Yukon, going from 108.9 cubic feet to 94.7 cubic feet. The extended-wheelbase 2015 Chevy Suburban and GMC Yukon XL similarly cede 16 cubic feet of total cargo area.
The excellent powertrains are taken directly from the 2014 Chevy Silverado / GMC Sierra, and incorporate all of their new tech including direct injection. This yields 355 horsepower and 383 pound-feet of torque from the 5.3L V-8 and 420 horsepower and 460 lb-ft of torque from the 6.2-liter, more than ample in either case to accelerate these beasts with authority. Fuel economy should be significantly improved. All models use a GM-made six-speed automatic transmission with tow/haul mode and an automatic grade-braking function. Other important new mechanical features include GM’s magnetorheological adaptive suspension damping, “duralast” brake rotors at each wheel that are projected to double service life and eliminate surface rust, and design revisions to the entire braking system to improve brake pedal feel.
Finally, GM touts that the 2015 Tahoe / Suburban / Yukon include a host of new security technologies that make them “almost impossible to steal.” An interesting assertion, but we’ll elaborate when we have further details.
In conclusion, this looks like a very thoughtful redesign of GM’s full-size SUV line. The 2014 Chevy Silverado / GM Sierra certainly upped the game in the full-size pickup class in many respects, namely refinement. We expect that those improvements in comfort and refinement will carry over here. The only negative in the 2015 Tahoe / Suburban / Yukon redesign is the reduction in overall cargo space. That negative however might be a very meaningful one for many potential car shoppers in this class.
