2024 GMC Sierra EV revealed with 754 horsepower, 400 miles of range

This is the 2024 GMC Sierra EV in all its Denali Edition 1 glory. You probably knew this was coming. After all, when Chevrolet debuts a new pickup, the GMC version of said truck is typically quick to follow. That’s exactly the case here yet again as the Sierra EV follows the somewhat recent debut of the 2024 Chevy Silverado EV. Per usual, the Chevy and GMC versions of the electric truck share a lot of similarities. TheyÂ’re also different in many of the same ways weÂ’re accustomed to within the GM pickup family. The biggest differentiator is design. If the Silverado EV wasnÂ’t your cup of tea, perhaps the Sierra EV is! Just like the Silverado EV, the Sierra rides on GMÂ’s Ultium platform. ItÂ’s being offered exclusively in Crew Cab form at launch. GMC designers emphasized its upright stance and proportions as typical truck styling. However, close examination will show a lot of curved edges and a focus on aerodynamics to achieve a lower coefficient of drag. The front grille is devoid of any flashy patterns, as GMC has opted to go for the shield aesthetic. Light is heavily used to bring a flash of design to the face — the whole grille features a light-up surround. A three-bar charging status indicator can be seen on the front end, and engineers intentionally mounted the headlights lower in the front fascia than usual. For the Denali Edition 1 (the only version of the Sierra EV available at market launch), all of the exterior trim is done in glossy black, except for the areas you might step on, which are finished in a flat black. The rear features GMCÂ’s MultiPro tailgate, and just like the Silverado EV, the Sierra EV comes with the fancy MidGate. GMC calls it the “MultiPro MidGate,” but itÂ’s the same tech used here as youÂ’ll see in the Silverado EV. With the MidGate down, you get nine feet of storage between the cab and the tailgate. Storage can extend out to 11 feet if you use the MultiPro tailgateÂ’s stopper feature with the tailgate down. Also, the MidGate can be folded with a 60/40 split, so you can get that extra length and still retain some backseat passenger room. All of the powertrain and battery tech is similar to the Silverado EV. That means you get a pair of electric motors for all-wheel drive capability with a combined output of 754 horsepower and 785 pound-feet of torque. YouÂ’ll need to be in “Max Power Mode” (we know, much less exciting than WTF mode in the Hummer EV) to realize all that power.

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.

MotorWeek looks back at 1995 Chevy Tahoe, GMC Yukon

MotorWeek's Retro Review series gives us a nostalgic look back at some of the best sports cars and luxury sedans available in the 1980s and '90s. For its latest clip, the show shifts gears to remember the 1995 Chevrolet Tahoe and GMC Yukon. Similar to the success of crossovers today, SUVs were tallying big sales and making big money for automakers in the mid-'90s. The Tahoe and Yukon filled slots in the market as steps down from the larger Suburban. These twins weren't wanting for space, though, with plenty of room to haul around a family. MotorWeek came away generally impressed too, and called the models some "of the better riding sport utilities we've ever experienced." This review comes with some jazzy, electric guitar licks to enjoy in the background.
