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.

GM to invest $632 million in Indiana plant for future pickup truck production

General Motors plans to invest $632 million in its Fort Wayne, Indiana, assembly facility to prepare the plant for future internal combustion engine full-size light duty trucks, it said on Monday. The investment will be used to support new conveyors, tooling and equipment for the plant that manufactures GM's Chevrolet Silverado 1500 and GMC Sierra 1500 trucks. GM has detailed more than $2.3 billion in planned investment in a series of announcements since last week as it works to retool existing North American auto plants and introduce more efficient next-generation internal-combustion full-size trucks and SUVs. Another investment announcement is planned later this week. The largest U.S. automaker is continuing to make big investments in gas-powered vehicles even as it vows to stop building them in 2035. Last week, GM said it was investing more than $500 million in its Arlington, Texas, assembly plant to prepare it for production of internal combustion engine full-size SUVs. GM faces increasingly stringent emissions requirements from California and the Environmental Protection Agency (EPA). Last week, GM also said it plans to invest more than $1 billion to re-tool two manufacturing sites in Flint, Michigan, to prepare for a new generation of its heavy-duty trucks. The Texas announcement highlights the company's commitment to continue "providing customers with a strong portfolio of (internal combustion) vehicles for years to come," GM said last week. On Tuesday, GM said it would invest C$280 million ($210 million) in its Canadian Oshawa Assembly to produce the next-generation internal combustion engine full-size trucks. GM paid $128.2 million in fines for failing to meet Corporate Average Fuel Economy (CAFE) program requirements for 2016 and 2017, records released recently show. The EPA in April proposed requiring a 56% reduction in projected fleet average emissions over 2026 requirements.

2014 Chevy Silverado High Country spied wearing trappings of new luxury trim

Spy photographers have spotted the new Chevrolet Silverado High Country and GMC Sierra Denali out on public streets for a little testing. From the looks of things, the Silverado will receive a much-differentiated front fascia along with special badges and those honking 20-inch chrome wheels. Expect to find a more posh interior as well. Likewise, the Sierra Denali will wear a tweaked nose with the familiar Denali bling. The one of the GMC trucks spotted here rolls on 21-inch gunmetal wheels instead of the 20-inch chrome pieces of the High Country.
Word has it both trucks will go on sale after the Texas State Fair this summer. While General Motors hasn't said for certain what we can expect to find under the hood, we'd be surprised to see anything outside of the range of engines found in the standard Silverado and Sierra models. That means buyers should be able to get their hands on the efficient, 23-miles per gallon 5.3-liter V8.
