Costco Auto Program adds the Chevy Silverado and GMC Sierra through July

Costco members lean to the Bowtie when it comes to pickups. The big box store wrote that the Chevrolet Silverado "is currently the most requested Chevrolet and pickup truck through Costco Auto Program and has been for the past 11 years. In the 14 years Costco has partnered with Chevrolet for member-only incentives, the Silverado (when included), has been the top selling vehicle every time." Members can rejoice, because just for the months of June and July, the Costco Auto Program has added the Silverado and the GMC Sierra to its Costco Auto Savings Event. Until July 31, 2024, card-carrying shoppers can get an additional $1,000 discount on top of any manufacturer incentives they qualify for when leasing or purchasing new examples of either. The Auto Savings event includes other vehicles as well, the $1,000 incentive applicable to certain other models from Chevy and GMC, as as well Volvo and Cadillac. Tire kickers considering the Polestar 2 can get $2,000 off.  You can check out our write-up on the Costco Auto Program for all the details and the frequently asked questions. The summary is that the store works with "selected" dealers to refer customers to, about 3,000 storefronts across most automotive brands. The program comes with no-haggle pricing for any straight-up purchase. Costco offers customers a research tool to check out vehicles by type and compare specs and features. After a customer zeroes in on a car, it's time to visit the dealership for a chat with an "Authorized Dealer Contact" to examine the vehicle and go over the fine print. Haggling would only arise if the customer has a trade-in; that valuation is between the customer and the dealer. The customer can check out the Costco Member-Only Price Sheet, which "displays your prearranged pricing. The savings can be displayed in one of two ways: One version lists pricing for all models available at the participating dealership; the other will show a VIN-specific price based on the vehicle you select, including any applicable manufacturer incentives or rebates." And for those looking on the battery-powered shelves, the program offers the same $1,000 off the Chevy Blazer EV and Equinox EV.

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.
