2024 GMC Canyon AT4X AEV Edition pushes the limits even higher

The GMC Canyon AT4X is already a formidable off-road pickup truck, but now it’s getting even more capable with the addition of the 2024 GMC Canyon AT4X AEV Edition. If youÂ’re familiar with the Chevrolet Colorado ZR2 Bison, then by proxy youÂ’re familiar with GMCÂ’s version of it already. Like the bow-tie version of the pickup, the AT4X AEV Edition is lifted an additional 1.5 inches beyond the regular AT4X, giving it 12.2 inches of ground clearance, which is identical to the ZR2 Bison. You also get to work with a 38.2-degree approach, 26.0-degree departure, and 26.9-degree breakover angle. ItÂ’s fitted with AEV beadlock wheels wrapping 35-inch Goodyear Wrangler Territory mud-terrrain tires and uses hot-stamped boron steel skid plates for the radiator, steering gear, transmission, transfer case, fuel tank and rear differential. Appearance-wise, the AEV Edition sports a new front fascia with integrated fog lights and larger fender flares that facilitate the bigger tires. It uses AEV stamped-steel front and rear bumpers that include heavy-duty recover points, and the front bumper is compatible with a winch. The rear bumper (below) is particularly clever, as it has easily removable plastic corners that can be replaced with 10 millimeter-thick steel skid plates for a little extra protection on the trail. YouÂ’ll find an AEV in-bed mount for the spare tire, too, as the big 35-inch tire doesnÂ’t fit in the usual under-bed storage spot. GMC wasnÂ’t ready to provide hard numbers for payload or towing, but expect the Canyon AT4XÂ’s specs to go down in a similar manner as the ZR2 Bison that lost 230 pounds of payload capacity and 500 pounds of towing. And yes, the AEV Edition retains the AT4XÂ’s high-output four-cylidner that produces 310 horsepower and 430 pound-feet of torque. You get all the other AT4X goodies, too, including things like the Multimatic spool valve shocks and electronic-locking front and rear differentials. It also gets the sweet off-road launch control system that initially debuted on the Bison that can adjust power in real-time based on the traction available off-road. On the inside, the AEV Edition adds three standard auxiliary switches that you can hook up off-road or overlanding accessories to. The truck is also fitted with AEV-embroidered headrests and AEV all-weather floor liners. Pricing for the AT4X AEV Edition isnÂ’t available quite yet, but GMC says itÂ’s expected to be available for customer orders later this year.

GM shows off 'digital vehicle platform' enabling more in-car tech and OTA updates

It appears to have dropped the sobriquet "Global B," but General Motors' new electrical architecture has bowed in drawings and video. This is the "digital vehicle platform" GM president Mark Reuss spoke to Reuters about in 2015, saying it would move a great deal of a vehicle's computer work to the cloud and enable over-the-air updates. Reuss took the microphone for the debut, too, saying, "Our new digital vehicle platform and its eventual successors will underpin all our future innovations across a wide range of technological advancements, including EVs and expanded automated driving." The system will go into production later this year, appearing in dealerships first either on the 2020 Cadillac CT5 or the mid-engined 2020 Chevrolet Corvette. Yes, these are the same electronics cited for delaying the launch of the C8 Corvette over excessive draw, security and getting the more-than-100 computer modules to communicate seamlessly. When Car and Driver asked about that, GM replied with "No comment." Volkswagen's having the same issues with the Mk8 Golf right now, though, so GM isn't alone, and this will be the new normal among OEMs for a while. What's certifiable is that the new architecture is robust enough to handle 4.5 terabytes of data per hour, which is five times what GM's current wiring can handle. And thanks to Ethernet connections of 100 Mbps, 1 Gbs and 10 Gbs, communication within and without the vehicle happens much faster. The advances mean better screen resolutions, better battery management for hybrids and electric vehicles, the capability for over-the-air updates and "functionality upgrades throughout the lifespan of the vehicle." Cadillac's Super Cruise has already been lined up as a leading candidate for constant improvements in the driving assistance suite, a key part of GM's "vision for a world with zero crashes, zero emissions and zero congestion." And whenever GM decides to take the plunge, it will mean a 48-volt electrical system. More than 300 specialists worked on the digital platform, and security was a huge part of the task. We've already heard that GM consulted with Boeing and military contractors on how to prevent hacking. The carmaker has an internal Product Cybersecurity group that reached out to the research community, and created a "bug bounty" program to crowdsource uncovering any flaws.

'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).
