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 Hummer EV hits Neiman Marcus Christmas catalog for twice the price

This winter season, Nieman Marcus is getting into the true meaning of Christmas by offering a bunch of seriously expensive stuff in its annual holiday catalog. There's usually at least one automotive offering, and this year it's a 2022 GMC Hummer EV Edition 1 for an eye-watering $285,000. That's $172,405 more than the regular Edition 1 crab-walker, which is priced by GMC at $112,595. And what does one get for more than 2.5 times the cost of the most expensive electric Hummer? Well, hold your 1,000 horses, because this isn't just any Hummer EV Edition 1. No, it's a one-off Barrett-Jackson Hummer EV Edition 1. The interior of this Barrett-Jackson edition Hummer has been "curated" by Craig Jackson himself. And by curated, they mean it has a bunch of red trim everywhere and is garnished with a Neiman Marcus logo. Aside from that, there is nothing appreciably different about it. No performance upgrades, no special paint job. You do get an electric charging station at home, though, which might be the most useful addition to this whole enterprise. If that's not worth the price of an entire 1.5 extra Hummers to you, there's more. You get two VIP passes for the opening gala of the Barrett-Jackson auctions in exotic Scottsdale, Ariz. During the auction, you'll get access for two to Carolyn and Craig Jackson's personal skybox from where you can watch 1,500 cars trade hands. But don't get too comfy, because at some point you'll be invited on stage to receive your Hummer EV in front of a gaggle of inebriated fishing boat dealership owners. Oh, and you'll also get to bang the little auction hammer. You can pair the Hummer with other gifts in Nieman Marcus' "fantasy" catalog, like a $6.1 million dollar diamond ring. However, if you go with the $395,000 Great Gatsby-style roaring '20s party, make sure it doesn't end with the 9,000-pound Hummer Daisy Buchanan-ing any bystanders.
