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.

2021 GMC Yukon Denali adds another extra-luxe accessories bundle

For the 2018 GMC Yukon Denali, GMC added a Denali Ultimate Package that combined every option already available with some 22-inch Midnight Silver rims. In 2020, GMC expanded build options for the Terrain with a Denali Premium Package, lumping together a couple of a la carte packages as an exclusive mix of features. The 2020 Yukon Denali configurator includes a lightweight Denali Premium Package, too, but for 2021 GM Authority reports the top-tier choices will expand to include an entry-level Denali Deluxe Package along with the Denali Premium and Ultimate options. The Deluxe Package checks the boxes for the Advanced Technology Package, Advanced Security Package, and the Rear Seat Media System. The long list of tech roped in with that trio includes adaptive cruise control, enhanced automatic emergency braking, rear camera mirror and washer, interior movement sensors, glass break sensors, dual 12.6-inch rear seat-mounted screens, two HDMI ports, and wireless projection capability. The exterior showpiece is a quartet of 22-inch bright machined aluminum wheels with premium paint, affixed with wheel locks. Go with those rims and the Denali Deluxe Package costs $5,750, opting for a different set of wheels can drop the price to $3,775. On top of that, choosing the right combination of options to go with the Deluxe Package can lower the price another $500. The Denali Premium Package includes almost everything above, only omitting the Rear Seat Media Package. In place of the screens for back-seaters, the bundle installs a powered panoramic sunroof and power-retractable assist steps with perimeter lighting. Purchased with the 22-inch wheels, this assortment runs $7,000, or $5,025 with a different set of wheels. Here again, the right combination of additional packages can save $500. The Denali Ultimate Package combines everything in the bundles above, plus the Max Trailering Package that gets GMC's ProGrade Trailering System and high-capacity engine cooling. The price is $10,460 on a rear-wheel drive Yukon Denali, $11,255 on the four-wheel drive models. Choosing a different wheel only saves $1,000 in this case, and there's no extra discount available. The 2021 Yukon is expected to enter production next month at GM's Arlington Plant in Texas, Related Video: This content is hosted by a third party. To view it, please update your privacy preferences.

GM announces net 220 job increase as Trump visits Michigan

GM announced today that about 900 jobs would be added (or, importantly, retained) ahead of President Trump's arrival in Michigan, where he is expected to discuss his plan to roll back fuel economy standards. The timing of the announcement is almost certainly not coincidental, as appending it to a Trump visit gives it a higher profile and dovetails with the President's jobs agenda. It's less likely the decision itself was made for those reasons, but the free PR boost is a nice bonus. As for those 900 jobs themselves, they aren't all new jobs. The only net gain is approximately 220 jobs at the Romulus Powertrain Plant, which produces the 10-speed automatic transmission that's proliferating through the company's lineup. The 180 jobs at Flint Assembly and 500 jobs at Lansing Delta Township are retained jobs – that is to say, spots the company found for workers who would otherwise have been laid off. By the way, the Flint jobs will help with production of heavy-duty pickups, and the Lansing jobs are to produce the Chevrolet Traverse and Buick Enclave. Finding jobs for manufacturing workers in the auto sector, whether new or retained, is admirable. No matter how GM couches it, the company has created or retained a total of 7,000 jobs this year, and its total reinvestment in US production is around $1 billion. But these decisions are business ones, not political ones – timing the announcements to make them seem inspired by economic policy, or the political situation, is simply smart PR.
