2015 Chevy Tahoe, Suburban and GMC Yukon unveiled

General Motors has today unveiled its new family of fullsize SUVs, including the 2015 Chevy Tahoe, its longer Suburban sibling, and their GMC Yukon, Yukon XL and Yukon Denali cousins. More efficient powertrains, improved aerodynamics, increased connectivity and better overall refinement are what Chevy and GMC say will separate their new SUVs from the current generation.
Sporting a tried-and-true body-on-frame architecture, these full-size SUVs feature platforms that are stronger and offer a wider rear track for "a more planted stance," according to Chevy and GMC. Mounted at the front of each SUV is an EcoTec3 powertrain, which consists of a standard 355-horsepower, 5.3-liter V8 (or a 420-hp, 6.2-liter V8 for the GMC Yukon Denali alone) with direct injection, cylinder deactivation and continuously variable valve timing, that's paired with a Hydra-Matic 6L80 six-speed automatic transmission. The setup is said to be more efficient than before, though official EPA fuel economies for each vehicle are not yet available. To help the powertrain achieve the best possible fuel economy in these 5,000+ pound SUVs, the new styling was developed with aerodynamics in mind. For the same reason, electric power steering also makes its debut in the Tahoe/Suburban/Yukon family.
The front fascias of the Chevy Suburban/Tahoe and GMC Yukon are distinct, but from the base of the A-pillars back, they share most of the same styling cues. This now includes inlaid doors that tuck into the door sills, instead of over them, which improves aerodynamics and fuel economy, and lessens interior noise. The hoods and liftgate panels now are made of aluminum in an effort to reduce vehicle weight. Chevy and GMC also tout that the Tahoe/Suburban and Yukon don't share a single piece of sheetmetal or lighting element with the brands' full-size pick-up trucks.

GM issues stop-sale for 3 SUVs over incorrect MPG rating

This week, GM sent a memo to Chevy, GMC, and Buick dealers to tell them to stop selling three SUVS. The 2016 Chevy Traverse, the GMC Acadia, and the Buick Enclave all have EPA window stickers that show higher fuel economy ratings than the vehicles actually have. Unlike other recent – and very public – fuel economy ratings problems from VW and Mitsubishi, it doesn't seem like GM did anything wrong with the testing for these vehicles, it just misprinted the labels. New labels are being printed and should arrive at dealerships this weekend and early next week. After that, the SUVs will be able to be sold and delivered again. The official fuel economy rating for the three SUVs are all the same. The correct numbers for the all-wheel drive versions are 17 miles per gallon combined, 15 city, and 22 highway. The stickers say the SUVs get 17/24/19. The front-wheel driver models were also incorrectly labeled, and the total number of affected vehicles is 59,823. In the memo, GM said the problem was caused by an "inadvertent error," Automotive News says. GM is working with the EPA to solve the issue. We have asked GM for a comment on the mistake and will update this post if we hear back. Related Gallery 2013 GMC Acadia View 16 Photos News Source: Automotive News – sub. req.

2018 GMC Sierra 2500HD All Mountain concept: Nothing stops it in its tracks

Winter may not be the best time for sports cars, but snow and ice can still provide a ton of fun in the right vehicle. The Porsche Macan GTS I had back in January was a riot in the snow, and it was wearing nothing more than a good set of winter tires. What you really need to conquer the frozen north is tracks. These replace wheels with the same sort of equipment that helps tanks and snowmobiles roll over damn near everything in their paths. That's what makes the 2018 GMC Sierra 2500HD All Mountain concept so awesome. That and the 910 pound-feet of torque from the 6.6-liter Duramax turbo diesel V8. The All Mountain concept is set to debut this week in Veil, Colorado, home to ski slopes, log cabins and nearly year-round snow pack. The truck is based off a standard GMC Sierra 2500HD. The turbo-diesel V8 makes 445 horsepower in addition to the mountain of torque. Power is sent to all four corners through an Allison 1000 six-speed automatic. The new treads come courtesy of Mattracks. The 150 Series tracks aren't cheap — well into five figures with installation — but they give you a nice 16-inch surface at each corner. Other changes and add-ons include graphics on the bodywork, a RIGID E-Series 30-inch light bar, LEDs on the wheel well and underbody, Thule snowboard racks, a roll-up tonneau cover and a new speaker system from Kicker. The truck will stay on display in Veil all winter, though a similar concept will be making its way to various auto shows, starting with Los Angeles next week.
