2017 GMC Canyon steals Cadillac's V6 for a little more power

GMC is fortifying the Canyon with a new powertrain and two new trim levels for 2017. GMC will give the Canyon the 3.6-liter V6 found in the Cadillac ATS, CTS, CT6, and XT5 crossover. The engine will be matched to an eight-speed automatic transmission, which also can be found on Cadillacs, the new 2017 Colorado, and other General Motors vehicles. The new engine comes with variable valve timing, improved direct injection, and Active Fuel Management, which is a form of cylinder deactivation that shuts off two cylinders to increase fuel efficiency and performance. Power is up from 305 to 308 horsepower, while torque increases from 269 to 275 pound-feet of torque compared to the old 3.6-liter V6. With the new transmission, the Canyon benefits from a higher first gear ratio, which should help drivers get off the line more easily when towing large cargo, and lower overdrive ratios for improved fuel efficiency. The 2016 model had a six-speed automatic. The Colorado also gets the eight-speed transmission for '17. GMC previously announced the All Terrain X and Denali models. The All Terrain X trim is offered on the SLE model and comes with the new 3.6-liter V6 engine or the 2.8-liter Duramax turbo-diesel. The All Terrain X gets Goodyear Wrangler DuraTrac P225/65R17 all-terrain tires, a body-color grille surround and matching rear step bumper, bespoke 17-inch aluminum wheels, and a spray-on bedliner. The truck also is fortified with Hill Descent Control and an off-road suspension. The Denali carries the flag as the most luxurious Canyon model and gets a Bose seven-speaker audio system, more chrome, and interior upgrades. In addition to the new models and the powertrain, the 2017 Canyon will be offered with new colors – Dark Slate Metallic, Mineral Metallic, and Red Quartz Metallic – a new IntelliLink radio with a seven-inch touchscreen, a heated steering wheel as an optional extra, and Standard Teen Driver Mode. The 2017 Canyon, with all of its changes, will be available in the fourth quarter of the year.

2018 GMC Acadia with 'Christmas Aero' modification gets in the wind tunnel

Tis the season of "Big" - big cheer, big parties, big bowls of eggnog, big decorations, and when it comes to your family hauler, big drag. Festive drivers who festoon their crossovers, minivans, and SUVs with wreaths, Rudolph noses, fuzzy antlers, and rooftop Christmas trees undo the years of work that car engineers devote to fractional gains in fuel economy. To put numbers to such fuel-guzzling madness, GMC started with a 2018 Acadia, optioned it with the Xmas Aero Package - both Standard and Plus versions - put it in Lockheed-Martin's wind tunnel. The resulting dip in fuel economy results probably won't surprise anyone who's used a roof rack - or, for that matter, their car's air conditioning. However, it might surprise you to find out which seemingly substantial decoration had no effect, and which seemingly innocuous decoration was about twice as bad as running the A/C on its Mr. Freeze setting. Check out the brief video above for the results. And consider placement of that bow carefully.

Pics Aplenty: Meet the 2014 Chevrolet Silverado and GMC Sierra [w/poll]

Today was a pretty big day for General Motors, debuting the all-new Chevrolet Silverado and GMC Sierra light-duty pickup trucks ahead of their official showcase at the 2013 Detroit Auto Show. And now that the dust has settled at GM's big reveal event, we've had a chance to snap dozens of photos of the new pickup pair from every angle.
We already told you the important bits earlier today (click here in case you missed it), but let's recap. Under the hood are three new engines - a 4.3-liter V6, 5.3-liter V8 and 6.2-liter V8 (you know, a version of the small-block that'll also be found under the hood of the C7 Corvette), all mated to six-speed automatic transmissions. The 2014 model year marks the return of the Z71 off-road package with Rancho shocks, front tow hooks and beefier underbody protection. Inside, there's a host of new technology and a greater focus on better quality and refinement.
Some of the nitty-gritty specifics (like engine output numbers and fuel economy) have yet to be revealed, and since we haven't driven the finished products yet, it's hard to say how these trucks will fare against rivals like the Ram 1500 and Ford F-150. For now, we can only judge these two books by their covers, and while we do like the designs of the new trucks, we Autoblog staffers are torn on exactly which one looks best.
