2014 Chevrolet Silverado and GMC Sierra debut all-new designs, three new engines

General Motors has finally dropped the curtain on the 2014 Chevrolet Silverado and 2014 GMC Sierra. Both trucks have undergone substantial revisions with updated versions of the company's 4.3-liter V6, 5.3-liter V8 and 6.2-liter V8 engines. In a shot across the bows of both Ford and Chrysler, GM says it won't use a V6 engine adapted from passenger car applications. Instead, it developed the 4.3-liter engine based on its proven truck-duty architecture.
All three mills will boast direct injection fuel systems as well as a new cylinder head design. Combined with a revised piston, the new engines feature a smaller combustion chamber with a compression ratio of 11:1 or higher depending on the application. Cylinder deactivation and continuously variable valve timing are all part of the recipe, and each engine is paired with a six-speed automatic transmission with auto grade breaking. So far, no fuel economy or horsepower figures have been released, though GM says the new engines will best their predecessors in both areas.
Outside, the trucks feature a number of enhancements to reduce drag and wind noise, and GM claims both the Silverado and Sierra will offer buyers some of the quietest cabins in the class. Extended cab models now feature front-hinged rear doors to allow easier access to the back passenger area, and Crew Cab buyers can now select between a five-foot, eight-inch bed or a six-foot, six-inch bed. Buyers with a mind toward going off road will also rejoice in the return of the Z71 package, complete with Rancho shocks, front tow hooks and additional under-body protection.

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:

GM reportedly recalling select 2014 Silverado, Sierra pickups over airbag issue

General Motors is recalling 843 2014 Chevrolet Silverado and GMC Sierra Crew Cab pickups, due to a fault with the vehicle's airbags. According to GM, the airbags may not inflate properly in the event of a crash. There haven't been any crashes or injuries associated with this recall, which is always good. Naturally, repairs will be free of charge, and GM will begin contacting affected owners soon.
GM has a lot hanging on the 2014 Chevrolet Silverado and GMC Sierra. Not only is it banking over $12,000 per vehicle on these trucks, as reported by Automotive News, but GM is counting on the Sierra and Silverado to take the fight to cross-town rivals Ford and Ram. The F-150 and Ram 1500 have been on a tear over the past few years, with fresh updates, advanced powertrains, and plenty of solid press while the GM trucks have been waiting for the 2014-model-year upgrades.
It's still entirely too early to judge the Sierra and Silverado, particularly as those 843 recalled trucks make up barely two percent of the over 40,000 units moved so far. But, as AN rightly states, these trucks are the most important vehicles to come out of GM since bankruptcy, with about 60 percent of global profits relating to pickups and SUVs. Starting an introduction of such a big product with a recall, however small, is not the preferred way to do things.
