Buick, GMC making OnStar Connected Services standard

The thing about the future is that so long as you're alive, you're going to get there whether you like it or not. Thanks to over-the-air connections essentially being a compulsory part of EV ownership and an increasingly important — and profitable — component of ICE ownership, it's easiest for automakers to install full-featured Internet connections in every vehicle. GM has taken the first step, a report in GM Authority saying that as of June 2, all Buick and GMC models are sold with the Onstar Connected Services plan good for three years. The OnStar site shows the Connected Vehicle tier that comes with a Wi-Fi hotspot costs $24.99 per month, which would be $900 minus a few pennies for three years. At the top end is OnStar Premium that runs about $1,800 for three years. Both include Connected Services features, yet GMA reports that depending on the vehicles, OnStar Connected Services will cost between $905 and $1,675. Only the GMC Hummer EV Edition 1 is excluded for now. GM confirmed the change to GM Authority, saying, "This offering provides our owners with a full suite of OnStar and Connected Services for three years, providing them with more time to enjoy services such as remote key fob, Wi-Fi data and OnStar safety services. By including this plan as standard equipment on the vehicle, it provides more customer value and a more seamless onboarding experience." Three trims of the GMC Sierra 1500 and two trims of the GMC Yukon and Yukon XL come in at the low end, OnStar adding $905 to their MSRPs. Almost every other vehicle gets hit with a $1,500 charge. The GMC Sierra HD Pro is the only model to charge $1,675 for it, which GMA breaks out as a "$1,500 3-year subscription and $175 OnStar & GMC Connected Services Capability." This brings up the question of the price differences; we can't tell if there's a difference in feature content between the price tiers, or why the Sierra HD gets the extra $175 fee. The automaker told GMA the upcharge will be folded into the MSRP. On the configurator for the Sierra 1500 SLE, for instance, the dialog box for three years of OnStar at $1,500 is automatically checked and can't be unchecked. The Buick configurators we tried don't mention OnStar.

'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).

Barrett-Jackson rundown: 2024 GMC Hummer EV, Colin Powell's Corvette and more

The echoes of the last hammer fall at Barrett-Jackson's Scottsdale Auction have disappeared into the Arizona night, as have the record crowds and the traffic jams. During the Super Saturday charity auctions, three main attractions drove onto the dais for bidding: Late U.S. Chairman of the Joint Chiefs of Staff and Secretary of State General Colin Powell’s 2015 Chevrolet Corvette Stingray, the hammer price benefitting AmericaÂ’s Promise Alliance, the nonprofit Powell founded to support kids; The first production 2024 GMC Hummer EV SUV Edition 1 with VIN 001, proceeds going to Tread Lightly!, which educates people on how to enjoy the outdoors in a motorized vehicle and simultaneously protect the outdoors; And the first production 2024 Ford Mustang GT Fastback VIN 001, its hammer price benefiting the Juvenile Diabetes Research Foundation. Before the Saturday showcase, charity auctions on Friday took Barrett-Jackson past a huge milestone. When an 800-horsepower 2021 Shelby Super Snake Count's Kustoms Edition hammered for $350,000 to support the veteran's charity Camp Freedom, the auction house officially surpassed the $150 million mark for charity auction proceeds. Piling on before the clock struck midnight, a 2023 Ford F-150 Lightning 4x4 Super Crew sold for $275,000, those funds donated to Fighter Country Foundation. Then came Saturday. Powell's Gunmetal Gray on black Stingray was said to be a daily driver, but with just 15,600 miles on the odometer, Powell — who died in 2021 — apparently had a very short commute. Equipped with an eight-speed automatic transmission and chrome wheels, it sold for $200,000. The first production 2024 GMC Hummer EV SUV Edition 1 ran the bidding up to $500,000. That's quite a ways down on the $2,500,000 that the bedded 2022 GMC Hummer EV Edition 1 garnered at the charity auction in 2021, and not a bad price all things considered. The owner gets the first one off the line instead of getting lost in the 90,000-order backlog, and the markup goes to a good cause instead of a flipper and eBay fees. The first production 2024 Mustang GT Fastback brought in both less and more than the Hummer EV. The Ford's hammer price came to $490,000. However, two additional philanthropic donations for this lot in the amounts of $50,000 and $25,000 took the final price to $565,000. The big movers on the day were outside the charity sphere, four cars breaking the million-dollar mark.
