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.

Inevitable GMC Canyon Denali spotted testing

Practically every other model in the GMC lineup already offers a more luxurious Denali option, so why not extend that to the Canyon midsize pickup? It's hardly a surprise to see the brand doing just that, especially since the standard model seems to be proving quite a success. This Canyon was recently spied testing wearing camouflage over its front end. The truck still needs to breathe, though, and the opening in the obfuscation makes it quite easy to spot the Denali's chrome mesh grille, rather than the horizontal slats of the standard model. Also, just peeking out of the bottom part of the masking is the lower air intake, which appears to be completely lined in chrome now. At the sides and rear, the styling is identical to the current look of the pickup, at least for this prototype. While our spies didn't snap any shots of the interior, it seems safe to anticipate the usual Denali upgrades there, including better materials and additional tech features. Of course, expect a bump in price at the same time to pay for the improvements.

Sunday Drive: Spying an automotive future of performance

I spy, with my little eye ... the future of the automotive world here in the United States. That pretty much sums up this week's Sunday Drive, in which we pull out the most popular stories on Autoblog of the previous week and try to draw some sort of conclusion as to what binds them all together. This week, it's spy shots, starting with one of the biggest and baddest muscle cars the world has ever seen: the Dodge Challenger Hellcat. The Hellish coupe gets a new hood for 2019 with dual scoops, but that's about the only meaningful change for the new model year. No matter. As long as it's packing 700-plus horsepower under those two hood scoops, all will be right with the world. Moving on, we take keep the performance angle but move it from the street to the dirt with a new version of the Chevy Colorado ZR2 that we think is probably called the Bison. We think it'll keep the high-tech suspension bits of the regular ZR2, but add expedition gear that may include a snorkel and a winch. Which, if true, is pretty dang cool. Keeping the truck theme is the 2019 GMC Sierra. There's nothing particularly noteworthy about the trim level in which the truck was spied, and that's what makes this specific example interesting. Base-model trucks almost never get much attention, but they sell in droves to workers who need an honest-to-goodness truck for work or play and don't care about bells, whistles, or massive chrome badges. And finally we have the 2018 Jeep Wrangler, which is on fire on the sales floor right now. But those are all V6-powered Wranglers flying off the showroom floor. Soon, a turbocharged four-cylinder engine option will become available, and now we know that it will return up to 23 miles per gallon in the city and 25 on the highway. That makes it the most fuel efficient Wrangler that Jeep has ever sold. As always, stay tuned to Autoblog this week for all the automotive news that's fit to publish. 2019 Dodge Challenger Hellcat with twin-scoop hood spied with no camouflage Chevy Colorado ZR2 Bison caught testing 2019 GMC Sierra 1500 spied in base trim level 2018 Jeep Wrangler four-cylinder fuel economy revealed Spy Photos Chevrolet Dodge GMC Jeep Truck Coupe SUV Off-Road Vehicles Performance dodge challenger srt hellcat sunday drive
