GM readying aluminum-body fullsize pickups

Ford's extensive use of aluminum in its 2015 F-150 is a big deal. A really big deal. Big enough, in fact, that General Motors is reportedly changing its fullsize pickup strategy. According to The Wall Street Journal, The General has locked in partnerships with Alcoa Inc. and Novelis Inc. - companies that will supply aluminum for the next-generation Chevrolet Silverado and GMC Sierra trucks.
"Ford's introduction of the 2015 F-150 pickup truck was a game changer, and it's the first, not the last, conversion of this type," Novelis spokesperson Charles Belbin told the Journal. The switch to aluminum has allowed Ford to shave roughly 700 pounds off its fullsize truck's curb weight. And while official mileage ratings have not been announced, the weight loss should go a long way for improving efficiency, especially when combined other efficiency-minded improvements including better aerodynamics and new, turbocharged V6 engines.
Of course, aluminum-bodied cars are nothing new. But extensive use of aluminum in a major, best-selling product like the Ford F-150 is expected to kick off widespread use of this weight-saving material as availability rises and cost decreases. The WSJ reports that GM had originally explored the idea of moving to aluminum pickups back in 2008, but abandoned the idea due to cost concerns amid economic woes.

A spotter's guide to Super Bowl LIV car commercials

Set to kick off on Fox at 6:30 ET on Sunday, February 2, from Hard Rock Stadium in Miami, Florida, the big game will feature the Kansas City Chiefs and the San Francisco 49ers. Throughout Super Bowl LIV, viewers will see about 50 commercials, each of which costs as much as $5.6 million per 30 seconds, according to AdWeek. Originally, there were more than 77 ad slots, so several companies could be paying well more than $10 million for a single, longer commercial. Numerous car companies have already announced their commercials, or their intentions to show commercials, during the game. Here's a roundup of the ones we know about so far. During the game on Sunday, we'll be livestreaming and adding links to the new commercials as they become available, so check back with us for that post.  Audi: E-Tron Sportback Maisie Williams has experience wearing many faces, and in Audi's Super Bowl commercial, she does her best Elsa impression. In the spot, titled "Let It Go," Williams faces the rigorous task of getting through L.A. traffic, but she's alleviated by the comfort of the Audi E-Tron Sportback electric crossover. The commercial is meant to signal the company leaving its gas past behind and moving forward to a sustainable future.  Genesis: GV80 Genesis makes its Super Bowl debut with a commercial that will show its all-new SUV, the GV80, to viewers around the world (many of which will be seeing the vehicle for the first time). The ad features Chrissy Teigen and John Legend as the purveyors of "new luxury," while "old luxury" is left for the birds. GMC: Hummer General Motors is bringing back the Hummer nameplate as a premium electric GMC truck. GM says it will have 1,000 horsepower and will be capable of going zero to 60 mph in three seconds. GM brought in NBA legend and Hummer fanboy LeBron James for the debut commercial. Hyundai: Sonata Hyundai is known for bringing in the big-time celebrities for its commercials, and 2020 is no different. A new advertisement called "Smaht Pahk" features John Krasinski, Chris Evans, and Rachel Dratch, all three of whom are from the Boston area. The trio gets into full character as they discuss the new high-tech parking feature on the redesigned 2020 Hyundai Sonata, and David Ortiz makes a cameo at the end. Even when New England isn't in the Super Bowl, New England is in the Super Bowl.

Chevy's 6.6-liter Duramax is pretty much all new

To say there's a heated battle in heavy-duty pickups is an understatement, with Chevrolet, Ford, and Ram constantly trading blows of increased torque, horsepower, and towing capacity. The latest salvo is the revised, more powerful turbo diesel 6.6-liter Duramax V8 in the 2017 Chevy Silverado. It has 910 pound-feet of torque, an increase of 145, putting it nearly level with the Ford Super Duty. Here's a closer look at where those gains come from. How exactly did Chevrolet add all that torque plus 48 horsepower? The automaker essentially took a fine-tooth comb to the entire engine. Chevy says it changed 90 percent of the V8, and the cumulative effect of those small changes adds up to big increases. As you might guess, the turbocharger is updated. The larger unit features electric actuation of the variable nozzle turbine (VNT), and what Chevy calls a double axle cartridge mechanism that separates the VNT moving parts from the housing. That helps with heat performance as well, with a claim that the exhaust side of the turbo can run continuously up to 1,436 degrees Fahrenheit. Helping that cause are six exhaust gaskets made of Inconel - an nickel alloy that contains chromium and iron – and upgraded stainless steel for the exhaust manifold. Despite having the same cast iron cylinder block, albeit with some minor enhancements, the engine has new cylinder heads, pistons, piston pins, connecting rods, and crankshaft, which have all been upgraded to handle 20 percent higher cylinder pressures. Alongside the increase in pressure, Chevrolet also increased the cylinder head's structure with a honeycomb design. The pattern features high-strength aluminum with dual layer water jackets that not only improve strength, but also optimize water flow for better cooling. For 2017, the cylinder head also benefits from integrated plenum that aids the engine in getting more air under heavy loads. The cylinder head isn't the only component to get a minor update, as the pistons have a larger diameter pin for improved oil flow. The same detailed improvements has been bestowed to the humble connecting rods (second in our hearts only to the inanimate carbon rod). The new design has the bolts oriented roughly 45-degrees to the rod instead of parallel. The angle split design, as it's called allows for easier passage through the cylinder.
