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 hybrid and electric Corvette, plus we drive the Ioniq 5 | Autoblog Podcast #728

In this episode of the Autoblog Podcast, Editor-in-Chief Greg Migliore is joined by Road Test Editor Zac Palmer. Zac drove the electric 2022 Hyundai Ioniq 5, and Greg drove the fire-breathing 2022 Maserati Levante Trofeo. The two dive deep into the relatively heavy news week by starting off with a discussion about the upcoming hybrid Corvette before chatting about what the electric Corvette might be like. They have a chat about the possibility of Porsche and Audi officially joining the Formula 1 field. Then, Greg and Zac get into some quick-hitting news to round out the segment by dissecting the updated Kia Soul (now without a turbo), the 30th Anniversary Edition Land Rover Defender and the new CEO at Aston Martin. Following the news and drive reviews, they rope in Senior Editor, Green John Beltz Snyder to give them a quick download of what went down at the first drive for the 2022 Ford F-150 Lightning. Finally, they reach into the mailbag and answer some questions from someone who is less than pleased about infotainment systems in some new cars. And lastly, the gang hears back from someone they helped out in a prior Spend My Money segment on the podcast. Send us your questions for the Mailbag and Spend My Money at: Podcast@Autoblog.com.

GM cutting production at two plants

General Motors is continuing to adjust to excess supply of some of its brands' models. To get production more in line with the vehicles' actual demand, the automotive giant is idling two of its factories in North America in the coming months. The Orion Assembly plant is going to be down from March 9-13, according to an anonymous plant worker and another insider speaking to Automotive News. The factory builds the Chevrolet Sonic and Buick Verano, but there are plenty of both models sitting on dealer lots, including 216 days worth of Sonics, according to AN. The factory already had two idle periods announced to reduce the excess. In addition, downtime is scheduled at GM's "Flex" line at the Oshawa, Ontario, Canada, plant from April 13-17. This affects supply of the Chevrolet Camaro, Impala, Buick Regal and Cadillac XTS. Among them, the automotive giant has the largest supply of Regals ready for dealers with 213 days worth of them, according to AN. The future for the whole Oshawa factory is cloudy in general, though. There are rumors that it could close entirely in the future because the Camaro is leaving and the Regal and XTS might not last much longer than 2017. The Canadian government and the labor union there intend to put up a fight, though.
