2015 Sierra All Terrain HD looks ready to hit heavy-duty trails

GMC is getting its heavy-duty trucks ready for the mud this summer with its All Terrain package for the Sierra 2500HD and 3500HD. Meant to blend style, tech and ruggedness, the pack includes a lot of extra chrome outside and an off-road package underneath.
The 2015 Sierra All Terrain HD trucks naturally come standard with four-wheel drive with an electronically controlled transfer case to handle things in the dirt. The Z71 off-road package is also standard, which includes Rancho twin-tube shocks, hill descent control and a skid plate. To add some style when off the beaten path, the pack includes chrome trim on the mirror caps, lower bumper and grille surround, plus LEDs around the headlights and 18-inch wheels (20-inchers are optional on the 2500HD). The 3500HD also gets chrome, adjustable outside camper mirrors. The interior receives a technology upgrade thanks to the standard rearview camera and IntelliLink infotainment that can act as a Wi-Fi hotspot through OnStar 4G LTE, read text messages and includes Siri Eyes Free for iPhone users.
The All Terrain package goes on sale on both trucks this summer and is offered on either the SLE or SLT trim levels in double cab and crew cab models. The standard engine is the 6.0-liter V8 with 360 horsepower and 380 pound-feet of torque, but the Duramax 6.6-liter, diesel V8 with 397 hp and 765 lb-ft is also available. The gas engine is mated to a Hydra-matic six-speed automatic, and the diesel uses an Allison six-speed automatic. Scroll down to read the full announcement about these heavy-duty off-roaders.

GM appears to repurpose Saturn Outlook parts on new Acadia

General Motors unveiled the company's refreshed GMC Acadia at the 2012 Chicago Auto Show yesterday, and if you were paying attention, you may have noticed something curious about the vehicle. While the new Acadia looks considerably better than its predecessor, a few components of the design looked more than a little familiar. Upon closer observation, it appears that GM has simply repurposed elements of the now defunct Saturn Outlook crossover on the 2013 Acadia. Both vehicles seem to share the same wrap-around rear glass, back hatch, tail light openings and exaggerated, squared-off fender arches.
While the vehicles are differentiated by badging, tail lamps and a rear valance, there's no denying the similarities toward the vehicle's rear. Up front, both share similar fenders, though adjustments have been made for the varying headlight designs.
That's good news if you just can't imagine life without the Saturn Outlook.

Big And Boxy Might Be Best
As immense fans of the Back to the Future trilogy, we sometimes like to envision an alternate timeline in which General Motors had killed off GMC and kept Pontiac instead. The G8 GXP would still be on the road handily beating German sport sedans costing twice as much, while the lowly G3 would morph into a true subcompact-killer based on what is now the Chevrolet Sonic RS. While we're at it, let's go ahead and imagine the G6 has become the best-selling car in the US and the Torrent crossover is selling 20,000+ units per month. Far-fetched, we know.
The thing is, these fanciful statements would have to be true to make the case against keeping GMC. Pontiac may have offered more excitement than GMC, but money talks, and a full line of trucks, crossovers and SUVs have made a lot more money for GM than the arrowhead brand ever did. How much? As we learned last month, about two-thirds of GM's global profits came from its fullsize trucks, and GMC's trucks typically have thicker margins than their Chevrolet counterparts.
