Chevy Silverado, GMC Sierra 4.3-liter EcoTec3 V6 nets 18 mpg city, 24 highway

There is no doubting that fuel economy has become an important factor in the highly competitive fullsize truck market, with the Ford F-150 EcoBoost V6 and Pentastar V6-powered Ram 1500 setting quite a precedent in recent years. Now it's General Motors' turn. The General has just announced that the new base V6 used in the 2014 Chevrolet Silverado and GMC Sierra 1500 models will return an EPA-estimated 18 mpg city and 24 mpg highway in two-wheel drive trim, regardless of cab configuration.
While these figures don't go so far as to earn GM any "best-in-class" fuel economy claims (thanks to the 25-mpg Ram 1500 HFE), this new 4.3L EcoTec3 V6 does edge the F-150 and Toyota Tundra while boasting best-in-class numbers for torque, payload and towing capacity among six-cylinder rivals. This all-new engine produces 285 horsepower and 305 pound-feet of torque, and it gives the 2014 Silverado and Sierra the highest towing rating among standard V6 models with a 7,200-pound towing capacity - besting the Ram by 700 pounds, the base F-150 by 1,100 pounds and coming within 200 pounds of the V8-powered Nissan Titan.

GMC Canyon AT4X rumored to get more extreme AEV Edition

When GMC debuted the new 2023 Canyon pickup in August, the midsize lineup gained the hardcore AT4X off-road trim the brand has been spreading throughout its wares. The new top-of-the-line model is GMC's version of the Chevrolet Colorado ZR2 and features the same off-road goodies, like the Multimatic DSSV suspension, unique front fascia, more skid plates, front and rear locking differentials, and a Baja drive mode turning the 33-inch tires. The Edition 1 launch model adds to the production goods by bolting on a front safari bar with a 30-inch light bar, a Comeup winch, an upgraded front skid plate, reconfigurable bed rails, front and rear underbody cameras, and special badging. The Canyon AT4X Edition 1 was gone almost immediately, because of course. However, Muscle Cars & Trucks reports that something just as special could be coming for buyers in the form of a Canyon AT4X AEV Edition. American Expeditionary Vehicles already breathed all over the last-gen Chevrolet Colorado and the current Chevy Silverado, looks like GM not only intends to keep the relationship going but expand it. MCT credits a source for news that the AEV-worked Canyon will get a snorkel and 35-inch tires. Chevrolet offered a snorkel as an aftermarket piece for the Colorado ZR2 Bison, and AEV sold a ZR2 Bison version with a snorkel attached. The new report claims GMC will make the elephant trunk a factory option, fitted to the driver's side this time instead of the passenger's side because of the new engine. The 35-inch tires would be a huge add-on, giving the Canyon the same kind of footprint as the Jeep Wrangler Rubicon Xtreme Recon and a couple of Ford Bronco trims. The additional two inches over the 33-inch tires on the AT4X make a big difference when the trail gets dicey. MCT says the AEV will get the same bumper as the Edition 1, which means a reduced approach angle in return for an integrated winch. The standard AT4X bumper permits a 36.9-degree approach angle, the winch-equipped Edition 1 drops that to 32.8 degrees. It's not clear which winch would hide behind that bumper, though. GMC factory fit is the Comeup Seal Slim 9.5rs rated at 9,500 pounds. AEV offers a Warn 9.5 XP-S with the same weight rating for its Colorado ZR2 Bison.  Speaking of which, since the Colorado arguably started all this, Chevy fans can expect their midsizer to acquire the same bundle as the Canyon AT4X AEV.

GMC teases Hummer EV's removable roof panels

Today was supposed to be the day that GM took the wraps off its GMC Hummer EV. We were told as much during the Super Bowl commercial, but GM revised it to an undecided future date, citing the coronavirus as the reason. Instead of the big reveal, we have a teaser.  The Hummer EV is going to feature removable roof panels, and now we get a better look at them. There are four roof panels and a front T-bar that come out of the truck. You can see what that looks like in the video at the top of this post. Comparisons to Jeep are obvious as the open-air experience is likely similar to the Gladiator and Wrangler with their hardtop roof panels removed. That zero-limits slogan makes a bit of sense from this respect. With the sheer number of roof panels, we suspect a single person will be able to remove them alone. In addition to the video of the roof, we get a small peek at the massive digital screens the Hummer will be sporting. Check them out at the bottom of the photo below. They appear to be two large slabs, separate from each other. Other details are scarce on the ground. We’re not sure when the Hummer will make its grand entrance at this point, but are still excited to see the 1,000-horsepower truck hit the road. GMC is still advertising the 0-60 mph time of just 3 seconds, too. The latest tidbit of news suggests that further teasers might be coming, so we could be in for a rather drawn out reveal process. Our senior green editor John Snyder got to see the GMC Hummer in person earlier this year at GMÂ’s EV Day and described it like this: “ItÂ’s a big, off-road-ready pickup complete with giant all-terrain rubber and tow hooks. It features removable roof panels for access to the open sky, which appears to be depicted in the teaser above. It features sail panels behind the C-pillars, similar to those on the Chevy Avalanche and Honda Ridgeline. Its bed was concealed with a tonneau cover, but it sported GMCÂ’s MultiPro tailgate that we first saw on the Sierra Denali. Interior photos showed a spacious interior with blocky shapes, squared hourglass vents that mirror the look of the taillights and a lunar theme that incorporates the topography of the Sea of Tranquility into things like the floor mats and speaker covers. It also has a large infotainment screen as well as a digital instrument panel.” Related video:
