2025 GMC Yukon AT4 teased, will likely follow 2025 Suburban template

It's time to begin teasing the 2025 GMC Yukon, the luxury truck division doing so with a glimpse of the front fascia on the AT4 trim. This being a refresh, we're not looking for major changes to hard points. In contrast to today's Yukon, it seems the new face will stress horizontal breadth instead of highlighting the central aspect of a giant grille and skid plate area. Starting with the taller C-shaped headlights on the 2025, a shorter horizontal element at the top no longer reaches all the way to the grille surround, and it's separated from the three main beams below by a body-colored piece extending from the grille cradle. Below the light, a new lower bumper treatment probably increases the aggression compared to today's truck. Instead of black centerpiece that houses the skid plate and a pair of tow hooks, it appears the entire bumper will be black and wrap around into the fenders. Finally, the grille looks the same, but its crossbars have been reprofiled.  As sibling to the 2025 Chevrolet Tahoe and Suburban that Chevy revealed last November, we expect many of the same updates here. Outside, that would mean refinements to the independent rear suspension for more nimble handling, new wheel designs, and availability of the second-generation 3.0-liter Duramax inline-six with 305 horsepower and 495 pound-feet of torque instead of today's 277 hp and 460 lb-ft. Inside, we expect a new instrument panel housing a 17.7-inch touchscreen for infotainment, and a column shifter replacing the push buttons on the center console. Updated trim materials — along with the overdue infotainment upgrade — should provide a finer sense of luxury than what's currently on offer.  If tech treats carry over, buyers will have access to the Connected Cameras feature for viewing and recording inside and outside of the vehicle for crash and security purposes. An Interior Motion Detection system can detect "micro-movements" in the cabin that could signal a baby or a pet left in the vehicle.  The Yukon might go further than the Chevy SUVs, seeing that GMC has some birthdays to celebrate: 2024 is the fifth anniversary of the AT4 trim and the 25th anniversary of the Denali trim. We'll find out later this year, GMC promising the Yukon reveal sometime after the new Acadia begins shipping to dealers.

'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).

Best trucks for the money in 2024, according to iSeeCars

Full-size trucks are some of the most popular vehicles on the road in the U.S., but they’ve become exceedingly expensive in some cases. That makes it even more important to choose the right full-size truck to maximize value and longevity. iSeeCars recently released its list of the best trucks for the money for 2024, ranking AmericaÂ’s full-size trucks on the cost to own over 10,000 miles. Though the Ford F-150 is the best-selling new full-size truck, it failed to break into the three best trucks for the money, landing at number four on the list. The top six pickups include: Chevrolet Silverado 1500: $2,863 per 10,000 miles Toyota Tundra: $2,868 Ram 1500: $3,352 Ford F-150: $3,469 GMC Sierra 1500: $3,598 Nissan Titan: $4,008 The list is short because there is only a handful of full-size trucks on sale. Though many are expected to last quite a while – some have lifespan estimates of more than 180,000 miles, and the Toyota TundraÂ’s average life is 226,032 miles – all of them are expensive. iSeeCars found that the average new truck purchase price is $61,353, with trucks like the GMC Sierra 1500 topping $66,000. iSeeCars ranked the trucks on their purchase price and 10,000-mile ownership costs, not on driving excitement, styling, tech, or safety. It also did not asses each truckÂ’s capabilities, such as towing and payload, but said that buyers looking to save money should only purchase one if they have “genuine truck needs.” The study looked at several vehicle types to find the best models for the money in each category. The Mitsubishi Mirage was the best car overall, returning a $1,099 10,000-mile ownership cost and a low $18,991 purchase price. The Toyota Tacoma was the best midsize truck, and Toyota landed a strong seven vehicles in the top 25 best cars for the money overall. Chevrolet Ford GMC Nissan RAM Toyota
