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.

GMC unveiling 2021 Yukon, Yukon XL on January 14

UPDATE: We received a reply back from a representative at GMC confirming that the new Yukon will be revealed on January 14. The text has been updated to reflect this. General Motors is renewing its body-on-frame SUVs, and GMC's Yukon is next in line to receive a full makeover. It's scheduled to break cover on January 14 alongside the long-wheelbase Yukon XL. It's reasonable to assume we would have gotten our first glimpse at the next Yukon during the 2020 Detroit Auto Show had the event not moved to June. The new date is too close to the model's on-sale date, so GMC will unveil it during a standalone event held in Vail, Colorado, according to GM Authority. We reached out to GMC, and a representative confirmed that is indeed the reveal date for the full-size SUV. Spy shots suggest stylists took GMC's two biggest SUVs in a sharper, bolder direction. Both models share the same front end, which borrows styling cues like C-shaped headlights from the Sierra pickup. Brand-specific rear lights help the Yukon models stand out from their Chevrolet-badged siblings, the Tahoe and the Suburban, which hasn't always been the case. The standard Yukon and the Yukon XL will each grow in size, though there's no indication GMC's naming structure will change to reflect that; Yukon XXL admittedly doesn't have much of a ring to it. While we haven't seen the interior yet, we expect it's getting a generous serving of technology, including a new, touchscreen-based infotainment system. The larger exterior dimensions will clear up more space for people and gear, so average-sized adults will be able to fit in the third-row seats. The range-topping Denali variants of both models will return to satisfy those who crave sumptuousness. The sheet metal will hide much of the same hardware found under the Tahoe/Suburban duo, including an independent rear suspension added in the name of comfort and handling. Powertrain specifications should carry over, too, meaning the entry-level engine will be a 5.3-liter V8 rated at 355 horsepower and 383 pound-feet of torque. The list of options will include a 6.2-liter V8 with 420 horsepower on tap, and we're betting the straight-six turbodiesel available on the Bowtie-badged SUVs will also be offered at an extra cost. Rear-wheel drive and a 10-speed automatic transmission will come standard, and buyers will be able to pay extra for four-wheel drive. The next GMC Yukon and Yukon XL will go on sale halfway through 2020 as 2021 models.

Chevrolet Malibu could last until 2024 before joining the dodo

Automotive News pieced together all available intel on the Chevrolet and GMC lineups, trying to ascertain how much life each model might have left. Concerning the Chevrolet Malibu, the answer is not too much, and the historic nameplate's final years don't look like the glory kind. After a major overhaul in 2016 boosted sales for the ninth-generation sedan to 227,881 units, the 2018 sales fell to 144,542, and this year's are down almost 15% through the end of June. The Malibu is one of two Chevrolet sedans still breathing - the other being the Impala for now - but only for about five more years. AN says there'll likely be a refresh in 2022, followed by a visit from the Reaper in 2024. After that, it could be "indirectly replaced" by an electric vehicle, one of the 23 EVs that GM is working on for 2023.     The Impala will meet the ax earlier despite a recent stay of execution. Production is still set to close in January 2020. In the entire GM stable, Cadillac might soon be the only marque with sedans. The Buick LaCrosse has a date with death, and Groupe PSA won't supply Opels-as-Regals forever.  The Sonic hatchback should say goodbye at the end of 2020, a year before the seemingly eternal Spark is thought to die. Two years after that, according to one report, the Camaro will go back into cold storage, perhaps forever, and AN says an "expected redesign of the car in 2021 was reportedly canceled." Finally, let's give one final shout-out to the Chevrolet Cruze, a global nameplate, which in the United States alone outsells the Malibu, outsold the Camaro by a factor of three last year, and absolutely trounces the Impala, Sonic, and Spark. Even that couldn't get a stay of execution. In more uplifting news, everything's happening on the crossover and truck side in the next few years. The Chevy Bolt is due for a refresh next year, even though it has "become more important for self-driving ride-hailing fleets that GM Cruise plans to operate than for consumers." In 2021, the Bolt-based crossover should bow, first in China, then here. It's said to look like "a mix of the Bolt and Trax" in spy shots. Still waiting for a green light: a possible subcompact GMC crossover called Granite that might make it to market by 2023. The full-sized SUV triplets Tahoe, Suburban, and Yukon could show their new faces in 2020. The Silverado might get an updated interior in 2020 or 2021, while the Colorado and Canyon mid-sized pickups won't get attention until perhaps 2023.
