when you hear the term "off-road SUV," with that distinction almost universally acknowledged to be held by the Jeep Wrangler. According to Jeff Luke, chief engineer for GM trucks, a surprising number of Tahoe and Yukon owners take their vehicles off-road and have shared their desire for a more off-road oriented suspension setup on the full-size SUVs, Automotive News reports. That being the case, Luke hints a more aggressive off-road package could be in the cards for the 2015 Chevrolet Tahoe, Suburban and GMC Yukon and Yukon XL.
The Tahoe and Yukon have long been offered with a Z71 package featuring upgraded shocks, tires, and special styling cues, but that trim has historically not represented a large percentage of the models' sales. The Tahoe and Yukon's body-on-frame construction and rugged solid rear axle have given them a more rugged reputation among owners and SUV buyers than unibody crossovers, which are perceived by many as being more delicate and less capable off-road.
Without committing to specific changes in the pipeline for the new SUVs, Luke said, "We're going to continually upgrade and add technologies, including in the powertrain area." Many perceive the last comment to be a tacit acknowledgement of an eight-speed or higher-ratio transmission coming for the SUVs, in pursuit of higher fuel economy.
