GM mulling off-road variants of fullsize SUVs

According to General Motors, owners "just love off-roading with [its fullsize body-on-frame sport utility vehicles]," namely the 2015 Chevrolet Tahoe and Suburban and GMC Yukon. If that's the case, it's a bit odd that sales of the previous generation of these models with the Z71 off-road package didn't sell particularly well.
Perhaps, considering this disconnect between owner's thoughts and desires with actual sales, it's not surprising that General Motors is reportedly "considering" an off-road specific model. That means the package would include styling changes and badges along with suspension modifications and larger wheels with appropriately sized fender flares.
There's no indication if the off-road model would be called Z71 or when it may potentially go on sale, assuming it ever goes on sale at all.

2019 GMC Sierra Denali and its nifty tailgate roll into dealers

We've got more details about the 2019 GMC Sierra Denali now that it's rolling into dealerships, starting with its floor price of $56,195, including destination fee, for the rear-wheel-drive models. That's a jump of $1,900 over the previous generation of its premium full-size pickup. Four-wheel-drive models start at $60,295. The crew-cab truck has grown in every dimension as well, adding about 4 inches to the wheelbase, nearly 2 inches in length and 1.2 inches in width. There's also nearly 3 inches more rear legroom. Bed options are 5-foot-8 or 6-foot-6. There are three engine options. Two are carryovers from 2018: a 5.3-liter V8 that sends 355 horsepower and 383 pound-feet of torque through an eight-speed automatic transmission, and an available 6.2-liter V8 that makes 420 hp and 460 lb-ft of torque and mated to a 10-speed automatic. Both come with GM's dynamic fuel management cylinder-deactivation technology to optimize power and fuel efficiency. A new 3.0-liter turbodiesel paired with a 10-speed automatic is expected in early 2019. The EPA hasn't yet released official fuel economy ratings, but GM estimates them at 17 miles per gallon in the city and 23 mpg on the highway for the two-wheel-drive versions, and 15/21 in four-wheel drive. The truck gets adaptive ride control which can adjust the dampers every 2 milliseconds based on real-time monitoring of the road and driver inputs for improved ride and handling. A new traction select system adjusts the transmission shift points, throttle mapping and StabiliTrak to tailor performance to different terrain or weather conditions. Inside the crew cab, there's new Forge leather-appointed seats, open-pore wood trim and dark finished aluminum decor, plus an 8-inch-diagonal HD color touchscreen with embedded navigation and Apple CarPlay and Android Auto compatibility. Most of the other new stuff we've covered before, including new C-shaped LED headlights and LED tail and fog lamps, optional 22-inch wheels, full-color head-up display, trailer-hitch assist apps and cameras, and rear-camera mirror. The truck also loses up to 360 pounds from the outgoing model via a scratch- and dent-resistant carbon-fiber bed box that replaces steel, and use of aluminum in the doors, hood and tailgate.

Leaked GM document shows GMC Sierra I6 diesel is more powerful than F-150's

GM told us earlier this year that the 2019 GMC Sierra would be getting a 3.0-liter I6 diesel option, but it never mentioned power or fuel economy figures. Hold the phone though, because a leaked GM Canada document just showed up online that lists out the details we've been waiting for. Originally published by TFL Truck, the 3.0-liter oil-burner supposedly makes 282 horsepower and 450 pound-feet of torque. For those who are counting, that's more than the Ford F-150's 250 horsepower and 440 pound-feet from its 3.0-liter diesel. It soundly bests the 240 horsepower and 420 pound-feet of torque from Ram's 3.0-liter diesel as well. Fuel economy is another story, though. The promotional material states that it will get 28 mpg on the highway, which is 2 mpg short of the F-150's 30 mpg — mind you, it's only capable of that magical 30 mpg figure in rear-wheel drive form. There's another caveat here, too; these are numbers for Canada, so they're not exactly finalized EPA figures. However, we wouldn't expect drastic differences between the two when the American numbers come out. The leaked documents also state the diesel Sierra will be capable of towing 7,800 pounds. That number seems remarkably low when compared to the F-150, which can tow up to 11,400 pounds with its diesel. Extra power and torque would have us assume that GM could get even better numbers than Ford, so we're going to hold our final judgment for official word. A 10-speed automatic will do the shifting on the diesel, just like on the 6.2-liter V8. Since the Chevy Silverado is also expected to get this engine, we can assume the figures would be almost, if not identical, to those we see here. We recently drove the 2019 Sierra and Silverado without the diesel engines, so go check those reviews out if you'd like to know more of our thoughts on the redesigned GM trucks. Related video:
