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.

2020 GMC Sierra Review & Buying Guide | The same but different

For the most part, the 2020 GMC Sierra 1500 and the Chevy Silverado are very close siblings. And with the more modestly equipped Sierra SLE and SLT models, choosing between the equivalent Chevy and GMC largely comes down to styling preference and whether you got a better deal at the GMC dealer. They’re almost identical twins. Almost. Because despite the shared DNA, there are differences in terms of model choice. There's no GMC equivalent to the cheaper Custom Trail Boss, for instance, but there is the high-dollar off-road-oriented AT4 that goes beyond the Chevy LT Trail Boss with more equipment and the availability of GMC's unique MultiPro tailgate and CarbonPro carbon fiber bed. Those are also available on the GMC Sierra Denali, which further differs with an adaptive suspension not offered by Chevrolet that seriously improves the ride comfort and handling composure of GM's full-size trucks. GMC therefore makes a compelling case for itself if you're willing to spend more for your truck, but having said that, the range-topping Sierras also don't go above-and-beyond in the same ways as the ritzy Ram 1500 and Ford F-150 trim levels do to provide a proper luxury truck experience. The new Duramax diesel engine at least stands out, but otherwise the Sierra doesn't offer a lot that others can't match or better (even within the GM family). What's new for 2020? CarbonPro Editions debut for the AT4 and Denali trim levels. These include the CarbonPro composite bed and a Kicker audio system in the MultiPro tailgate. The AT4 versions also gets some unique exterior trim. Mechanically, a 10-speed automatic is now paired with the drivetrain combo of 5.3-liter V8, Dynamic Fuel Management and four-wheel drive. Aiding visibility are newly available trailer tow mirrors, a bed-view camera, and a high-def 360-degree camera system with trailering elements.  What's the interior and in-car technology like? Like its Silverado sibling, the Sierra's cabin is its least compelling and competitive attribute, falling far behind the Ram 1500 and Ford F-150 in terms of quality and design. The dash is drab and frankly ugly in every trim level, but the cabin is particularly damning in the Sierra Denali. Its black vinyl "stitched" onto the black dash and some token strips of wood trim slapped onto the center console and doors just aren't enough to create the sort of high-dollar ambience truck buyers can find elsewhere.

Trucks with the best gas mileage for 2024

There's no denying that pickup trucks are an integral part of our culture. They've been instrumental in building our infrastructure and giving the public access to remote locations and myriad recreation activities. Trucks aren't known for being particularly fuel efficient though, with boxy silhouettes and considerable weight negatively affecting their gas mileage ratings. The times are changing and not only are trucks getting more economical, but there are also several new smaller alternatives. An efficient tuck doesn't have to by tiny, though. Some of the trucks with the best gas mileage look classically bulky. What is the most fuel-efficient truck? So what's the most fuel-efficient pickup truck on sale in the U.S? It depends on which class of trucks you're looking at. For this list, we're focusing only on internal-combustion trucks. The small crop of all-electric trucks are certainly worth considering, but it's not so easy comparing EVs to ICE trucks here. In most cases, these trucks are the two-wheel-drive versions since they return the best mileage, but there are a few four- or all-wheel-drive models that we call out.  Not surprisingly, the revival of the compact pickup has altered the truck landscape. In many cases, these petite trucks may be just the right size for many shoppers. That's great because most owners would rather not lug around a ton of weight that they don't necessarily need. The simplest answer to the question posed above is the Ford Maverick Hybrid. It tops this list of fuel-efficient truckswith an impressive 37-mpg EPA estimate for combined city and highway miles. With only 191 horsepower and a continuously variable transmission, it's not as capable off-road or for towing as other trucks, but if you just need something to haul stuff around, you really can't do any better. Its 4.5-foot bed has a slight advantage over its only rival, the Hyundai Santa Cruz, which has a 4-foot bed and an estimate of 23 mpg. So now we know what truck uses the least amount of gas. 2024 Ford Maverick 2.5-liter hybrid powertrain 37 mpg combined (EPA estimate) What is the most fuel-efficient midsize truck? While not as popular as their full-size siblings, midsize strike a good balance of utility and drivability. They’re easier to navigate in a crowded parking lot, and fit down more trails earning a set of Arizona pinstripes.
