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.

More Corvette Stingray Factoids: Vanishing panel gaps and 26-mpg LT1

During January's Detroit Auto Show, we managed a longer than expected wandering tag-team interview with C7 Corvette chief engineering exec Tadge Juechter (pictured above), and LT1 engine boss Jordan Lee (pictured below). They are, quite honestly, two of the very nicest bigshot lads to ever walk the engineering corridors of an American manufacturer. Both are enthralled by what they're doing for a day job. So are we.
We've followed the pre-sale anticipation for the Chevrolet C7 Corvette Stingray like an Oreck vacuum yanking every speck of dirt from a well-trampled carpet. Everything is reportable and contains a grain of further knowledge about this dramatically important and cheered-for car, as it continues to be pressured into representing all that is superior about the American dream. The Corvette wears one heavy cloak.
So, most of what was talked about has been expertly reported already right here on Autoblog. But, looking through our notes again, both Jeuchter and Lee added facts to the buzzing mix.

Chevy murders out Trax crossover with new Midnight Edition

Leaning towards a new Chevy Trax, but think it needs a little bit more attitude? Chevy has you covered with the release of the new Midnight Edition. It's based on the Bowtie brand's smallest crossover, but injects some extra style with its murdered-out treatment. The new Chevy Trax Midnight Edition is based on the top LTZ trim, and upgrades with black wheels, bezels, molding, door handles, and more. Inside, the cabin is adorned with gray-accented seats and gray-piped floor mats. It isn't a huge transformation, but may be just the dose of attitude that Chevy's little crossover needs. Otherwise it's the same Trax introduced a year ago, and comes equipped with a 1.4-liter turbo four good for 138 horsepower and 148 pound-feet of torque. It's available in either front- or all-wheel drive, and will return a claimed 34 miles per gallon on the highway in the former setup. The Midnight package adds an extra $500 to the $26,125 base MSRP on a new Trax LTZ.

Based on the LTZ trim, the Midnight Edition features black wheels, bezels, beltline molding and door handles, along with a black rear license plate applique. Inside, the seats are trimmed with gray accents and the floor mats feature gray piping. "Introduced just a year ago, the Trax has quickly become an important vehicle for Chevrolet, bringing in new, younger and more female buyers to the brand," said Betsy Flegg, senior marketing manager, Chevrolet Crossovers. "The small SUV segment is the fastest growing in the industry and models such as the new Trax Midnight Edition provides customers an expressive option." Trax sales were 57,707 for the first 11 months of 2015, placing it second in the segment, with almost 20-percent market share. Chevrolet crossover sales were up 35 percent for the same period. Fusing small-car agility and utility convenience of an SUV, Trax offers up to 48.4 cubic feet of cargo space. A 1.4L turbocharged engine offers the efficiency of a small displacement engine – an EPA-estimated 34 mpg highway (FWD models) – with the power of a larger engine on-demand. Connectivity features include an available 4G LTE Wi-Fi hotspot.
