2019 GMC Sierra AT4 First Drive Review | Off-road overkill

The road ahead is dirt with a rut here and a rock there. Brush keeps a respectable distance on the right side, the edge on the left gradually falls away into the valley below. The grade is nothing your treadmill couldn't duplicate and traction is pretty good. Honestly, a couple in their Subaru Crosstrek could pop up here for a picnic. The 2019 GMC Sierra AT4 we're driving is therefore complete overkill. But at least it looks the part as it trudges up this uncharacteristically verdant mountain with San Diego in the distance to the north and Mexico to the south. Its special, dechromed AT4 grille has a purposeful appearance, but tastefully lacks the show-off machismo of Ford and Ram's off-roading models. The red tow hooks are a nice touch and the dark-accented 20-inch wheels wrapped in all-terrain rubber are just the right size beneath a suspension that is raised an extra 2 inches from every other Sierra. That would be one of the key elements that differentiates the AT4 as the Sierra's off-roading model – GMC's answer to the Chevy Silverado's Trail Boss trims. In fact, their mechanical enhancements are identical. Besides the 2-inch lift, the suspension features off-road-tuned Rancho monotube shocks. There's also a locking rear differential, a two-speed transfer case, skid plates and those tow hooks. The 5.3-liter V8 with Dynamic Fuel Management is similarly standard, but unlike the Silverado Trail Boss, the Sierra AT4 offers the 6.2-liter V8 good for 420 horsepower and 460 pound-feet of torque as a roughly $2,500 option. That's the engine we have and it delivers the expected punch, complete with a satisfyingly snarling exhaust note. However, as observed in back-to-back drives with these two available engines during the Silverado launch, the 6.2 certainly isn't necessary. The 5.3-liter is seriously capable and the bigger engine is largely for those who want to have the biggest number possible emblazoned on the fender. It's overkill, which in this particular environment, is fitting. Besides the available engine upgrade, the AT4 also goes beyond its Trail Boss counterpart by dipping into the Sierra Denali's tool box. Its MultiPro tailgate is standard equipment, allowing for six different configurations, the most notable of which include a means of more easily reaching into the bed and a drop-down step that eases entry into the bed. GMC's considerable touting of that last element is rife with hypocrisy given GM advertisements that mocked Ford's similar feature.

2018 GMC Terrain loses the V6 and gains a diesel for an all-turbo lineup

You may have noticed that compact crossovers are kind of a big deal these days. After eight years on sale, GMC is finally getting a new version of its littlest ute, the Terrain, for 2018. And it can't arrive a moment too soon. The 2018 GMC Terrain made its debut tonight on the eve of the 2017 Detroit Auto Show. The 2018 Terrain looks to be completely new, and is now built on GM's D2XX platform. It again shares a platform and major components with the Chevrolet Equinox; like the 2018 Equinox, the Terrain will offer three engines, including two turbocharged gas four-cylinders and a turbodiesel four. The base 1.5-liter gas four makes 170 horsepower and 203 pound-feet of torque, while the 2.0-liter inline-four puts out 252 hp and 262 lb-ft. (The 2.0 basically takes the place of the 3.6-liter V6 offered in the outgoing Terrain.) GM's 1.6-liter diesel four will also be available, making 137 hp and 240 lb-ft of torque in this application. Both gas engines will be paired with nine-speed automatic transmissions, while the diesel gets a six-speed auto. No fuel-economy claims have been made, but we expect the new models to outdo the current versions, with the diesel reaching around 40 mpg on the EPA highway cycle. View 14 Photos The new Terrain's design is equally fresh and does a good job of differentiating it from the related Equinox, with details very reminiscent of the new GMC Acadia. The lighting elements are even more intricate here, with LEDs used for the daytime running lights and taillamps. GMC designers gave it the floating-roof look, which is successful aside from the odd placement of a trim badge at the base of the D-pillar. Terrains will again be available in SL, SLE, SLT, and range-topping Denali trim, with the latter featuring the signature satin chrome grille, chrome accents, and monochrome paint scheme GMC uses on all of its top-trim models. The interior sees an upgrade in materials and a more-thoughtful layout, with a new version of GM's Electronic Precision Shift gear selector using buttons and switches instead of a lever to open up more space on the center console. Both front- and all-wheel-drive models get a Traction Select system that will tune the shift points and throttle points for specific driving conditions via a knob at the rear of the console. On models equipped with all-wheel drive, a front-drive mode disconnects the rear axle to improve fuel economy.

2014 GMC Sierra 4.3L V6 to offer segment-best 305 LB-FT

General Motors has released more information on the 4.3-liter V6 available in the 2014 GMC Sierra. The engine will serve up 285 horsepower and 305 pound-feet of torque, with a six-speed automatic transmission, and giving the V6 Sierra a maximum tow rating of 7,200 pounds in regular cab, short bed four-wheel drive configuration. GM claims that figure is 500 pounds more than the equivalent Ford F-150 equipped with a 3.7-liter V6, and 700 pounds more than the Ram 1500 with its 3.6-liter V6. Buyers can expect to see the 2014 GMC Sierra with the 4.3-liter engine start at $25,085 including destination.
While the engine does deliver more torque than either of its main competitors, it falls short on the horsepower front. The 3.7-liter V6 in the F-150 develops 302 hp while the 3.6-liter V6 in the Ram 1500 yields 305 hp. GM says fuel economy estimates for its newest entry will land later this year.
