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.

2019 GMC Sierra interior looks just like the Silverado's

The GMC Sierra has pretty much always been a Chevy Silverado in disguise. There was maybe some fancier trim plus the availability of the ritzier Denali trim, but the differences mostly amounted to different makeup on identical twins. As we can see from the spy photos above, the yet-to-be-shown 2019 GMC Sierra will actually have a more distinctive exterior, but the interior will continue the me-too tradition. Immediately apparent is the fact that the whole dashboard is carryover. It's the same chunky, plasticky place to be that, while likely highly functional, did little to impress when unveiled at the Detroit Auto Show. Really, only the volume, tuning and climate control knobs look different from those in the Silverado. They appear to have a different ridged pattern on the edges, and are possibly a shinier, glossier finish. The steering wheel also looks different, with a chunkier center and more svelte spokes. The Sierra exterior would seem to be better differentiated. The headlights are very different in that they wrap around the fenders more so than on the Chevy. The grille looks more vertical and aggressive than the Silverado's. The wheel arches also differ in that the forward corners are rounded and the rears are more squared off. The GMC Sierra will be revealed March 1 in Detroit. As per usual, it will probably share all of its powertrain bits with the Silverado. That means at least 5.3- and 6.2-liter gasoline V8s and the new turbocharged 3.0-liter inline-six diesel engine. Related Video: This content is hosted by a third party.

'Killing a Duramax' Gale Banks YouTube series methodically tunes a diesel to death

Learning or perfecting a skill by watching YouTube videos is known as attending YouTube University. GM Authority picked up on one of the video site's more fascinating courses, hosted by Gale Banks; in a fair world, he should be referred to as Professor Banks when it comes to diesel engines and truck tuning. A few months after GM introduced the updated L5P 6.6-liter Duramax diesel V8 in the 2020 Chevrolet Silverado HD and GMC Sierra HD that ships with 454 horsepower and 910 pound-feet of torque, Banks decided he wanted to methodically tune the engine to death. The purpose of the resulting series, called "Killing a Duramax," is to push more power out of the engine in order to discover which parts break and when — or, as Banks puts it, force-feed the Duramax "until the crank hits the street and the heads hit the hood." With that knowledge, Banks can figure out all the weak points on his way to building what he calls a "Superturbo," that being a supercharged, twin-turbo race engine with more than 1,000 hp. What makes the series fascinating is Banks' knowledge, paired with the company's comprehensive iDash engine monitoring system that keeps tabs on a glut of parameters every step of the way. So for instance, you get Banks explaining the differences between inches of mercury and barometric pressure, how those are different from the water content of the air measured in grains, then showing those readouts on the iDash, then explaining in detail how they affect the air density in the Duramax system. The stock Borg-Warner variable turbo gets a lot of airtime — Banks accuses it of being "out to lunch" because he feels it's the weakest link on the engine. That turns into a turbo teardown and a deep explanation of performance pitfalls, such as when air pressure on the turbine begins to diverge from the boost pressure coming from the compressor. Banks says he can keep close tabs on where power's coming from, because the iDash monitors the horsepower contribution provided by the ambient air, the turbo, and the intercooler separately. The major changes so far are a stouter Precision 7675 turbo and TurboSmart wastegate (episode 5), a twin intake (episode 6), a custom liquid-cooled intercooler from a marine engine, a new GM oil cooler and synthetic oil (episode 10), and new injectors (episode 11).
