Barrett-Jackson is auctioning the first 2022 GMC Hummer EV for charity

Unveiled in late 2020, the GMC Hummer EV Edition 1 was so popular that enthusiasts scooped up the entire production run in merely 10 minutes. If you missed your chance to reserve one, you're in luck if your pockets are deep enough. Auction house Barrett-Jackson will sell the first example off the production line for a great cause. VIN 001 will be up for grabs during a sale that starts in Scottsdale, Arizona, on March 20. Hummer production hasn't started yet, so we don't know precisely what the truck will look like and it won't physically cross the auction block. Barrett-Jackson did not provide a pre-auction estimate, but it pointed out that 100% of the proceeds from the sale will be donated to a charity called Stephen Siller Tunnel to Towers Foundation that helps wounded first responders and veterans across America. Charity auctions normally bring big dollars, so a sold-out flagship variant of a highly-anticipated model whose base price is pegged at $112,595 could sell for a seven-digit sum. Edition 1 deliveries will start in the fall of 2021, meaning the winning bidder will need to wait a few months before exploring the great outdoors in the 1,000-horsepower electric truck. More affordable trim levels are in the pipeline, but they're not exactly around the corner. GMC will expand the range by launching three trim levels called EV2, EV2X, and EV3X, respectively. Equipped with three electric motors, the EV3X will land in the fall of 2022 with a $99,995 base price. Pricing for the two-motor EV2X due out in the spring of 2023 starts at $89,995, while the entry-level EV2 will arrive a year later priced at $79,995. None of these figures include available incentives. Looking ahead, the Hummer EV will spawn an SUV that will make its official debut online in February 2021. We don't know when it will reach showrooms yet, but we're not expecting to see it until 2022 at the earliest.  Barrett-Jackson's Scottsdale sale includes sports cars from every era, ranging from a custom 1928 Ford Model A to a 2021 Honda Civic Type R. Ram's first 1500 TRX is on the roster, too, and it will also be sold for charity. Another stand-out car from the catalog is the first production version of the 2020 Chevrolet Corvette Convertible. Finished in black with a black and red leather interior, it's powered by a mid-mounted, 6.2-liter V8 engine rated at 495 horsepower, and it's equipped with the 3LT and Z51 packages plus the Performance Data Recorder, among other features.

GM alerting truck and sedan owners to a do-over on brake recall

A recall campaign intended to address issues with braking systems on certain 2019 General Motors trucks and sedans may have introduced a new issue, the automaker has acknowledged, and thousands of owners driving repaired vehicles may need to return to their service departments for another update.  The update addresses a fix that was pushed out to owners of more than half a million brand-new GM trucks and sedans that could potentially lose partial braking function, according to the Detroit Free Press. The original software fix helped address situations where the vehicles' anti-lock braking systems would become disabled, which in turn would prevent electronic stability control from activating. Vehicles subject to the recall would often experience software glitches that prevented them from properly communicating the operational state of these systems, meaning drivers would have no idea that their brakes may not behave as expected in an emergency. The 2019 Chevrolet Silverado 1500, Cadillac CT6, and GMC Sierra 1500 were all recalled in the original campaign.  Unfortunately, the early version of this fix appears to have introduced yet another software glitch, indicating that the original fix did not do the trick. Those who have not yet had their cars serviced can rest easy; they will only receive the most up-to-date version of the software fix.  Related video    

Next-gen Chevy Silverado and GMC Sierra may use carbon fiber

It's been generally accepted that the next generation of full-size GM trucks will use some sort of strong, lightweight material for the beds while retaining steel for the cab. While aluminum seems like the most obvious choice, according to Automotive News, the Chevy Silverado and GMC Sierra will incorporate both aluminum and carbon fiber in their beds. The publication cites sources from within GM, though it seems the introduction of this comparatively exotic material mix is still a few years off. While carbon fiber is both stronger and lighter than steel and aluminum, it takes significantly more time and money to produce, essentially relegating the material to small-volume cars. The main benefit for trucks is the resulting reduction in weight to improve fuel economy without sacrificing the tough, rugged capabilities truck buyers expect. The Ford F-150 made the switch to aluminum for the 2015 model year and it's proved highly successful. It seemed like it was only a matter of time before the competition followed suit. Automotive News says that the next-gen trucks will launch with aluminum beds and that it will take a couple of years before we'll see any carbon fiber incorporated into the design. Even then, only look for the composite material on higher-trim models, with a trickle down to lower-spec trucks possible further in the future. In 2011, GM announced it was working with Japan-based Teijin Limited on a carbon fiber reinforced thermoplastic. There's a good chance that material's introduction will be on trucks.
