GMC Sierra 1500 AT4X: Can you sleep in it?

Autoblog may receive a share from purchases made via links on this page. Pricing and availability are subject to change. The recently introduced GMC Sierra AT4X is an impressive combination of off-roading and luxury. But can you sleep in it? Pickups are great for towing campers or as a platform upon which to build out overlanding rigs, but from the factory they usually aren’t as useful as SUVs to sleep in, considering half of the length of the vehicle is taken up by the bed. Let's see how the AT4X fares. Space The biggest thing to consider when it comes to camping in your car is whether or not there is enough space in it for you and possibly a partner to lay down comfortably. This is tough when it comes to pickup trucks, which are hampered by the fact that half (or more) of the length of the vehicle is taken up by the bed of the truck. Some trucks have added features like lie-flat seats that make sleeping in them a bit easier, though itÂ’s still not a perfect solution. Unfortunately the AT4X is not one of those trucks. While the seats do lay back quite a good amount, I wasnÂ’t able to get comfortable enough to rely on them for a good nightÂ’s rest. To the rear we go. If youÂ’re vertically challenged, you may be in luck, especially if you donÂ’t sleep stretched out. The Sierra 1500 is a wide truck, almost 7 feet wide in fact. The rear bench measures 56 inches in width, which isnÂ’t a great option for most adults unless you really like sleeping in the fetal position. ItÂ’ll do in a pinch but I wouldnÂ’t expect to get a great night's sleep again and again.  Below the bench, which folds up and out of the way, is a relatively flat floor which can offer a bit more length. At 63” it still isnÂ’t enough for me to lie down with the doors closed, but it is much less cramped than spending the night on the bench. The subtle bump in the middle of the floor, which is much less severe than the ridges in the bed, can easily be remedied by an inflatable sleeping pad like the Sea to Summit Ether Light XT, or, even better, a cheap air mattress from Walmart. The Bed The bed of the AT4X seems like the most logical place to sleep. After all, it is named the bed for a reason right? If you have an inflatable mattress, then sure, but due to the ridges on the floor, a simple sleeping pad and sleeping bag will not be enough here. Additionally, the length of the bed leaves something to be desired.

2015 GMC Yukon and Yukon XL hit the floor at LA

The middle child of General Motors' trio of truck-based SUVs, the GMC Yukon and long-wheelbase Yukon XL, received their auto show debut at today's 2013 Los Angeles Auto Show. Showing off a bigger, bolder look, particularly on its Denali trim, the Yukon sports prominent chrome grille instantly identifies GMC's new top-end SUV.
The Yukon is will come to market with a pair of engines. The base 5.3-liter V8 pumps out 355 horsepower and 383 pound-feet of torque, while the higher-end models benefit from the same direct-injected, 6.2-liter V8 as the Escalade. That engine makes 420 horsepower and 450 pound-feet of torque, with fuel economy seeing a likely boost thanks to an active fuel management system. Like the Tahoe, Suburban and Escalade, the Yukon takes advantage of a six-speed, column-mounted automatic transmission.
The cabin has seen significant upgrades in terms of materials and technology, with an eight-inch touchscreen display and IntelliLink standard in both Yukon and Yukon Denali. Fold-flat second and third-row seats come standard, while a power option is available, as well. Other techy features include active noise cancellation and standard Bose stereos.

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.
