2023 GMC Sierra prices up, start at $38,995 for Sierra Pro Regular Cab

It was only 90 days ago that GM Authority, typically a reliable source in these matters, reported on pricing for the 2023 GMC Sierra lineup before official numbers were released. Those early figures were apparently just placeholders. Now that GMC's uploaded the full 2023 configurator for the 2023 Sierra, not only are MSRPs higher except on the base trim, the destination charge has risen from $1,795 to $1,895. The sticker prices including destination and their changes from those late August sums are: Sierra Pro Regular Cab Standard Box 2WD Turbo 2.7L I4 L3B $38,995 ($1,025 less) SLE Double Cab Std Box 2WD Turbo 2.7L I4 L3B $52,095 ($1,100) Elevation Double Cab 2WD Turbo 2.7L I4 L3B $53,795 ($1,200) SLT Crew Cab Short Box 2WD 5.3L V8 L84 $57,795 ($1,300) AT4 Crew Cab Short Box 4WD Turbo-diesel 3.0L I6 LZ0 $68,595 ($1,495) AT4X Crew Cab Short Box 4WD 6.2L V8 L87 $83,595 ($3,395) Denali Crew Cab Short Box 2WD 5.3L V8 L84 $67,595 ($1,095) Denali Ultimate Crew Cab Short Box 4WD Turbo-diesel 3.0L I6 LZ0 $82,940 ($745) The Sierra's price bumps ranging from $745 to $3,395 come in tandem with the prices of the 2023 Chevrolet Silverado going up anywhere from $800 to $1,800. The $3,395 MSRP boost on the Sierra AT4X skews the price curve because of extra equipment. GMA reported in July that the standard AT4X would inherit parts from the Sierra ATVX AEV created in collaboration with American Expedition Vehicles. That's what's happened. A revised grille with gloss black and dark nickel trim, AEV front and rear bumpers with increased approach and departure angles, a hot-stamped hardened steel front skid plate inflate the cost and give the ATX4 a little more capability off-road. The equipment list also narrows the gap from the regular AT4X to the AT4X AEV, the latter going just a bit further with four more skid plates, AEV's Salta wheels, and a smattering of black trim around the body. We're still waiting for official pricing on the AT4X AEV. The image above shows shows how similar both trucks will look when the AEV arrives, with the standard AT4X on the left, the AT4X AEV on the right.

New Takata problem results in recall of 414 GM vehicles

An airbag-inflator rupture discovered by Takata during testing has resulted in a new recall affecting 414 vehicles from General Motors, including 395 of them in the US. This latest campaign covers 2015 model-year examples of the Buick LaCrosse, Cadillac XTS, Chevrolet Camaro, Equinox, Malibu, and GMC Terrain. There are no reported breaks in any of these vehicles on the road, and the company estimates only one percent of them actually have the faulty parts. According to documents submitted to the National Highway Traffic Safety Administration (as a PDF), one side-airbag inflator failed a cold test at -40 Fahrenheit "releasing high pressure gas and propelling the separated components apart." The supplier told GM about the failure the next day. In these vehicles, the safety device might not only burst but the bag could inflate incorrectly, as well. GM and Takata say that a cause is not yet known, but they are "conducting an investigation." GM will begin notifying affected owners via overnight mail on Oct. 19. Dealers will replace the side airbag modules on all of the affected vehicles with new components outside of the suspect lot. All of the removed parts will also be collected for further study. Takata's faulty front airbag inflators have resulted in a serious scandal for the supplier. Initial figures indicated 34 million US vehicles are need of repair, though more recent figures have knocked that down to 23.4 million bad parts in 19.2 million automobiles. GM was already among the dozen automakers with models to fix, and some of its pickups were affected, along with the Saab 9-2X and Pontiac Vibe. GM Statement: General Motors is recalling 395 cars and crossovers in the U.S. because one of the front seat side air bags inflators may be defective. In the event of a deployment, the air bag's inflator may rupture and the air bag may not properly inflate. The rupture could cause metal fragments to strike the vehicle occupants, potentially resulting in serious injury or death. GM is unaware of any incidents involving vehicles with these components, which were part of a lot in which one inflator failed acceptance testing at the supplier. Dealers will replace the side air bag module or modules in affected vehicles. Including Canada, Mexico and exports, the total population of the recall is 414, GM estimates 1 percent of the recalled vehicles may have the defect.

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.
