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.

GM workers in Oshawa walk out in protest of plant closure

TORONTO/MONTREAL – Canadian Prime Minister Justin Trudeau on Monday expressed his "deep disappointment" in General Motors' decision to close its Oshawa plant, a move Canadian officials only learned about on Sunday and which led workers to walk off the job on Monday. GM said the closure affects a total of 2,973 assembly line jobs. GM's total employment in Canada is 8,150 direct jobs. Workers in the Unifor trade union walked out of the Oshawa plant "in protest," ahead of a meeting with GM about the announcement, a union spokeswoman said. "I've moved my family twice for this company and they do this to me," a tearful worker told CBC TV as he left the plant. Currently, the Oshawa plant builds the Cadillac XTS and Chevy Impala sedans. Under Unifor's four-year contract signed in 2016, GM must give the union a year's notice before closing the plant. The automaker intends to close the plant in December, 2019. A 2015 study commissioned by Unifor, which represents GM employees, estimated that shutting the plant would eliminate 4,100 direct jobs and reduce Ontario's gross domestic product by C$1.1 billion. But Jerry Dias, president of Unifor, said the move amounts to a breach of the automaker's contract with its employees. "We have a collective agreement that says they're not closing any of our facilities ... so we will do anything by any means to make sure that they live up to their word," Dias said at a news conference. Dias said the contract between Unifor and the company forbids GM from closing any of its Canadian plants during the contract period, which ends in September 2020. "They are not closing our damn plant without one hell of a fight." Canadian officials promised to aid auto workers affected by the 2019 closure, part of a wider restructuring by the automaker that will cut production of slow-selling models and slash its North American workforce. "I spoke with GM (CEO) Mary Barra to express my deep disappointment in the closure," Trudeau tweeted on Monday. "We'll do everything we can to help the families affected by this news get back on their feet." GM workers have been part of the heart and soul of Oshawa for generations - and we'll do everything we can to help the families affected by this news get back on their feet. Yesterday, I spoke with @GM's Mary Barra to express my deep disappointment in the closure.

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.
