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.

The best Super Bowl car commercials from the last 5 years

If you've been dipping into the Autoblog feed over the past days and weeks, you wouldn't even have to be a sports fan to know the Super Bowl is coming up. Automakers have been teasing their spots for the big game, dropping them days early, fully-formed onto the Internet and otherwise trying to amp up the multi-million-dollar outlays that they've made for air time on the biggest advertising day of the year. And, we're into it. The lead up to the Super Bowl is almost akin to a mini auto show around these parts; with automakers being amongst the most prolific advertisers on these special Sundays. The crop of ads from 2015 looks as strong as ever, but we thought we'd take a quick look back at some of our favorite spots from the last five years. Take a look at our picks – created from a very informal polling of Autoblog editors and presented in no particular order – and then tell us about your recent faves, in Comments. Chrysler, Imported From Detroit Chrysler, Eminem and a lingering pan shot of "The Fist" – it doesn't get much more Motown than 2011's Imported From Detroit. With the weight of our staffers hailing from in and around The D, it's no wonder that our memories still favor this epic Super Bowl commercial (even though the car it was shilling was crap). Imported really set the tone for later Chrysler ads, too, repeated the formula: celebrity endorsement + dramatic copy + dash of jingoism = pulled car-guy heartstrings. Mercedes-Benz, Soul teaser with Kate Upton One of our favorite Super Bowl commercials (and yours, based on the insane number of views you logged) didn't even technically air during the game. Mercedes-Benz teased its eventual spot Soul with 90-seconds worth of Kate Upton threatening to do her best Joy Harmon impression. (Teaser indeed.) It doesn't win points for cleverness, use of music, acting, or any compelling carness, but it proved that Mercedes' advertisers knew how to make a splash in the Internet Age. And, hey, it's still classier than every GoDaddy commercial. Kia, A Dream Car. For Real Life Like the Mercedes video above, the initial draw here is a pretty lady; in this case the always stunning Adriana Lima. But this Kia commercial really delivers the extra effort we expect while scarfing crabby snacks and homemades, too. First of all, Motley Crue. Second, a cowboy on a bucking rhino. Enjoy yet again.

Two More Recalls Push GM Total To 4.8 Million In A Month

General Motors announced two more recalls late Friday, bringing to 4.8 million the number of cars, trucks and SUVs the automaker has called back for repairs in the past month. The string of recalls, topped by an ignition switch problem in compact cars now linked to 13 crash deaths, has embarrassed the company and sidetracked its new CEO, who started work just over two months ago. GM has admitted knowing about the switch problem a decade ago, yet it didn't recall any cars until February. The recall delay has brought two congressional investigations and probes by the Justice Department and the National Highway Traffic Safety Administration. Late Friday night, GM announced it would recall 490,000 late-model pickup trucks and SUVs because transmission oil cooling lines weren't secured properly in their fittings. Transmission oil can leak from a fitting and hit hot surfaces, causing fires, the company said in a statement. GM said it knows of three fires and no injuries. The recall affects Chevrolet Silverado and GMC Sierra 1500 pickup trucks from the 2014 model year, as well as 2015 Chevrolet Suburban and Tahoe SUVs and the GMC Yukon and Yukon XL SUVs. All have six-speed automatic transmissions. The Silverado is GM's top-selling vehicle and an important profit center for the company. The GMC Sierra also is among GM's top sellers. Dealers will inspect the transmission oil cooling line fittings and make sure they're securely seated, at no cost to owners. Also Friday night, GM announced the recall of 172,000 Chevrolet Cruze compact cars because the right front axle shaft can fracture and separate while being driven. The recall affects cars from the 2013 and 2014 model years equipped with 1.4-liter turbocharged four-cylinder gasoline engines. If a shaft fractures, the wheels would lose power without warning and the cars would coast to a stop. GM says it has warranty reports of several dozen shaft fractures. It is not aware of any crashes or injuries. Dealers will replace the shafts free of charge. The recall allows dealers to resume selling affected Cruzes. GM issued a stop sale order on the cars Thursday night. The recall also covers about 2,500 replacement shafts used to fix manual transmission Cruzes that were recalled last September. In all, GM has recalled 4.8 million vehicles since last month, two million more than the company sold last year in the U.S.
