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.

GM cutting back on powertrain warranty citing lack of interest

Generally, when a manufacturer offers a long, high-mileage warranty, it's a sign that it stands behind its products. On top of that, it's generally a selling point for consumers, who can rest easy knowing that any catastrophic failures will be picked up by the manufacturer. Considering those facts, it does seem rather strange that General Motors is slashing the mileage warranty on model year 2016 vehicles from Chevrolet and GMC. Instead of offering consumers a 100,000-mile warranty, GM will now only offer a powertrain warranty up to 60,000 miles. The five-year warranty period, though, remains unchanged. GM will also cut the number of free services being offered to Chevy and GMC owners, as well as Buick drivers, from four to two. "Through research, we have determined that when purchasing a new vehicle, included maintenance and warranty rank low on the list of reasons why consumers consider a particular brand over another," explained a memo sent to dealers by Chevrolet VP Brian Sweeney and his GMC counterpart, Duncan Aldred, and obtained by Automotive News. "As a result, we have benchmarked our competitors, reviewed our current offerings and have concluded the following modifications to align closely with our customers' needs and expectations." While the move might seem odd, Sweeney and Aldred are right – according to Automotive News, Ford, Honda and Toyota each offer a five-year, 60,000-mile powertrain warranty. As for what the money saved by trimming the powertrain warranty will go towards, a GM spokesperson simply told AN that the company will "reinvest the savings we will realize into other retail programs," some of which have been requested by consumers. What are your thoughts? Would a 40,000-mile reduction in a new vehicle's powertrain really turn you off from buying one? Even if it matched its competitors? Is GM better off spending its money elsewhere? Have your say in Comments.

GM delays 3.0-liter Duramax diesel in Silverado and Sierra pickups

Stricter testing protocols around the world are making it harder for automakers to predict launch timelines. GM is the latest to get caught in emissions nettles, the Detroit carmaker forced to delay the launch of its new Duramax 3.0-liter inline-six diesel for the Chevrolet Silverado 1500 and GMC Sierra 1500. That's what company reps told dealers in a memo seen by Automotive News this week. Dealers and buyers had been promised the Flint, Mich.-built oil-burner in early 2019, but AN wrote that the EPA certification hiccup has turned into a "slight delay." A GM spokesman told Motor1, "[We] did not attribute [the delay] to a single entity, as the truth is this is a collaborative effort between GM and several government entities. We will make the 2020MY Duramax available for dealers orders soon, and expect to deliver the first trucks to customers soon after emissions testing is complete." We know the new 3.0-liter Duramax diesel has 277 horsepower and 460 pound-feet of torque, outdoing Ford's 3.0-liter PowerStroke diesel by 27 hp and 20 lb-ft. But without final EPA paperwork, GM can't release the numbers that will show how the two engines stack up when considering fuel economy and tow ratings. The certification process has been sticky for a few other makers of late, especially since the Volkswagen Group situation in 2015. BMW had to delay the launch of four diesel models in 2016 over EPA testing. The new Ram 1500 dribbled out in a trickle last year for reasons thought to deal with EPA testing, coming as it did a year after the EPA investigated Ram's EcoDiesel engines in 2017 and 2018. More recently, WLTP testing in Europe caught out just about every automaker over there. Since we're almost halfway through 2019, the delay until the 2020 model year is only a few months. Still, GM told dealers to cancel any orders for the engine for this model year. Dealers will need to resubmit the orders once opening begins, but GM hasn't said when production will begin other than "soon." The company said that it will offer 2020-model-year replacement vehicles to customers and dealers. If prices hold into the next model year, the 2020 Silverado 1500 and Sierra 1500 with the inline-six diesel will come at a $3,890 premium over the 2.7-liter turbo four-cylinder, and a $2,495 premium over the 5.3-liter V8.
