GM files for Z71 Trail Boss trademark

Try as they might to keep their plans a secret, automakers have their hands tipped through a variety of methods – be they through loose lips, spy shots or patent and trademark applications. That's how we know, in this instance, that General Motors is working on (or at least considering) an off-road machine wearing the name Z71 Trail Boss – the name which our compatriots at AutoGuide.com tell us that GM has registered for use on light-duty trucks. Now if that alphanumeric designator sounds familiar, it should. GM has long used it to designate the off-road packages on many of its body-on-frame trucks from Chevy and GMC. These days you can order a Z71 package on the Chevy Colorado, Silverado, Tahoe and Suburban and on the GMC Canyon, Sierra and Yukon. The package typically includes components like a beefed-up suspension bits, high-capacity air cleaner and underbody protection plates. The Trail Boss designator would seem to suggest something further reaching than a suspension package, though. Just what it would entail we don't know; minds immediately start running toward Chevy or GMC going after the Ford F-150 Raptor, but we'll likely be looking at something closer to the Trailhawk packages Jeep offers on the likes of the Renegade and Cherokee.

2020 GMC Acadia refresh brings a new engine, AT4 trim level

It's mid-cycle refresh time for the GMC Acadia, and the updated 2020 model kicks off its changes with a new face. It has a square-jawed grille seemingly pulled straight off the Sierra full-size pickup, and the size is amplified by the slender new LED headlights on either side. At the rear, the LED taillights are taller and more chiseled. A new AT4 trim level adds more visual distinction with black trim and wheels, plus all-terrain tires to make it a little more capable off road. The AT4 also boasts standard all-wheel drive. Under the revised skin, the Acadia hides one of two carryover engines, or a new turbocharged 2.0-liter inline-4. This new engine makes 230 horsepower and 258 pound-feet of torque with the help of a twin-scroll turbocharger. To make it more frugal, it's able to deactivate two of its four cylinders. The turbo engine is standard issue on the SLT and Denali trim levels. The carryover engines include a naturally aspirated 2.5-liter 4-cylinder making 193 horsepower and 188 pound-feet of torque, and a naturally aspirated 3.6-liter V6 making 310 horsepower and 271 pound-feet of torque. The V6 is standard equipment on the AT4 trim. No matter the engine, all 2020 Acadias get a 9-speed automatic transmission. The new transmission also ditches the current Acadia's mechanical shift lever in favor of an electronic shifter with the Terrain's mix of buttons and triggers. It does free up space between the seats, but the button arrangement is still as strange as it was when we first saw it in the smaller crossover. There are a handful of other little upgrades to mention. The suspension has been revised for greater comfort; the infotainment has been revised with a bigger screen, USB-C inputs and customizable profiles; and wireless phone charging is now an option. The updated Acadia goes on sale this fall, and pricing will probably be announced close to launch.

Redesigned 2021 GMC Yukon gets a diesel, AT4 model, Denali-exclusive interior

GMC's most robust family hauler is getting a complete redesign for the 2021 model year, including a new, off-road centric AT4 model, an upscale interior exclusive to its luxurious Denali model, an available air suspension, and, last but not least, a diesel engine.  With Americans obsessing over trucks, it's no surprise that GMC is going hard with its AT4s-for-everybody strategy; the Yukon is no exception. This will be the first model year for the new trim on GMC's largest SUV. This off-road model gets all the goodies you'll need to veer off the beaten path with confidence, including an extra 2.0 inches of ground clearance with the adaptive suspension option (more below), a two-speed transfer case, standard Goodyear all-terrain tires, an off-road mode for GMC's "Traction Select" drive mode system, hill descent control, and some extra underbody skid plates. Since GMC is a premium brand, even the AT4 gets some luxury appointments, such as a heated steering wheel, heated and ventilated front seats, and heated outboard second-row seats. The interior is also adorned in black leather with tan accents and "AT4" embroidery in the seat backs.  Speaking of premium, GMC will introduce an air-ride adaptive suspension with an off-road ground clearance mode as a late-availability option for several Yukon models, and this feature will be included on the Denali trim.  The Yukon and Yukon XL are GMC's variants of Chevrolet's full-sized SUVs, the Tahoe and Suburban. Their fundamental body-on-frame architecture is also shared with GM's half-ton pickup trucks, and thanks to that common engineering, they can also share powertrains. That's normally just a trivial side note when it comes to a new GM SUV announcement, but this time around, it's a bit more meaningful thanks to the introduction of a new light-duty, inline-six diesel in GM's truck lineup last year.  Yep, that means that for 2021, like the Tahoe and Suburban, the Yukon is getting a diesel option. The 3.0-liter Duramax makes the same 277 horsepower and 460 pound-feet of torque as it does in GM's trucks.  GMC's standard engine is still the 5.3-liter V8 that makes 355 hp and 383 lb-ft of torque. The 6.2-liter V8 is also an option like before, producing 420 hp and 460 lb-ft of torque. All engines come with a 10-speed automatic and a choice of rear- and four-wheel drive.
