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.

Optimus Prime and Bumblebee head for auction

This month at the Barrett-Jackson auction in Scottsdale, AZ, the customized 1992 Peterbilt 379 of Optimus Prime from the Transformers series and director Michael Bay's own 1967 Chevrolet Camaro SS for Bumblebee will cross the block. The company will sell both with no reserve, and they'll come with letters of authenticity. This specific Bumblebee is the mean-looking restomod from Transformers: Age of Extinction, the fourth installment in the franchise, and Bay apparently liked it enough to hang onto the aggressive coupe after filming. He even autographed the car for this sale. The Camaro would make a great star in a Hollywood chase scene with its LS3 V8, six-speed manual gearbox, Wilwood brakes, and custom suspension. Bumblebee also wears a menacing satin black body with yellow accents and custom carbon fiber fender flares. Optimus Prime's Peterbilt appeared on-screen in the first three Transformers films, the auction house's spokesperson Aaron Cook told Autoblog. An Autobot emblem sits proudly on top of the grille, and the truck wears a flame paintjob. Barrett-Jackson's description says that the semi is fully functioning but no longer street legal and is now for display only. It would likely be the ultimate piece in anyone's Transformers collection.
