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.

Chevy Silverado Midnight Edition coming to Chicago

Between the GMC Canyon Nightfall Edition and Chevy Silverado Custom Sport, the truck divisions of General Motors had no lack of blacked-out custom pickups to showcase at the Detroit Auto Show this year. But now the General has announced one more. Called the Midnight Edition, for this special Silverado blacks out all the trim, including the grille, bumpers, headlamp bezels, tow hooks, fog lamps, side and beltline moldings, 19-inch wheels, bedliner and bowtie emblems. It's based on the Silverado 1500 with the Z71 package, so it also boasts an off-road suspension, locking rear differential, hill-descent control and trailering pack. While it was at it, Chevy has also thrown in rear park assist and power heated door mirrors. Buyers will be able to choose between double- or crew-cab models, but no more than 5,000 examples will be produced this year, each priced at a premium pegged between $1,595 and $1,995 (depending on the model). The Silverado Midnight edition debuts today at the National Automobile Dealers Association convention in San Francisco and will be showcased at the Chicago Auto Show next month, around the time that deliveries will commence. 2015 Silverado Midnight Edition is The New Black Monochrome appearance package to debut at NADA and Chicago Auto Show 2015-01-22 DETROIT – Truck fans know that nothing adds presence to a pickup like basic black. And Chevrolet is taking black to the next level with the Silverado Midnight special edition, on display starting today at the National Automobile Dealers Association Convention & Expo in San Francisco, and making its public debut February 14 at the Chicago Auto Show. Beginning with a black Silverado Z71, the Midnight special edition adds: - An all-black front end with body-colored grille, bumper, headlamp bezels, tow hooks and fog lamps; - Black side moldings and beltline moldings; - 18-inch black painted alloy wheels with Goodyear Wrangler Duratrac all-terrain tires; - Special Z71 badges on the doors; - A spray-in bedliner (black, of course); - And the finishing touches – black Chevrolet bowties front and rear. Like all 2015 Silverado 1500 Z71s, Midnight special editions include off-road suspension, a locking rear differential, Hill Descent Control and a trailering package. Midnight special editions also include rear park assist and heated, power-adjusted outside rear-view mirrors.
