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.

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.

GMC rules out subcompact crossover to go premium, focus on trucks

Don't wait for GMC's on-again, off-again baby crossover any longer. The company confirmed it has no plans to enter the growing car-based subcompact crossover segment in the near future because the expansion wouldn't fit its image. "I'm going to give you a definitive no on that one," answered Mark Alger, a regional marketing manager for GMC's Canadian division, when asked about the entry-level segment by GM Authority. "We want to position GMC as a premium brand, focus on our trucks, and capitalize on the AT4 name," he added. Positioning GMC as a premium brand wouldn't prevent officials from giving an entry-level the green light; Audi, BMW, and Mercedes-Benz all sell cars priced in the vicinity of $30,000. Focusing on trucks like the Sierra and the Canyon makes sense, however, because they compete in a bigger segment of the market where profit margins are much wider. It helps that GMC doesn't have to worry about markets outside of North America; it's not concerned about its sales and image in, say, Spain. We've heard speculation about GMC's entry-level model since the Granite concept (pictured above) made its debut during the 2010 Detroit auto show. It was approved for production in 2010, approved again the following year (complete with rear suicide doors), and canceled in 2012, but the reports never went away. The segment's popularity added credibility to the recent murmurs describing a born-again Granite aimed at the Honda HR-V and the Toyota C-HR, among others. The Chevy Trax and Buick Encore are both GM vehicles that compete in this segment.  GMC also canceled a body-on-frame, Bronco-taming SUV, according to a recent report. The truck-focused automaker promised every nameplate in its range will receive the rugged AT4 treatment by 2021, however, and it announced plans to show the off-road-ready Canyon in early 2020.
