GM planning to put its fullsize pickups on a big diet, too

General Motors is just coming off a complete redesign of the Chevrolet Silverado and GMC Sierra for 2014, but in the US fullsize truck market, there is no rest for the weary. According to Reuters, plans are already unfurling for both trucks to drop pounds from their curb weight over the next few years, but this will unlikely be able to keep pace with the 700-pound diet targeted for the next-generation Ford F-150, a truck expected to debut late next year.
The biggest weight reduction for these trucks might not be available until the next full redesign, which will likely happen around 2019, but the article says that smaller updates could shave pounds in the meantime. Two examples given include an "aluminum-intensive" version of the Silverado that could shed 250 pounds and debut around the same time as the lighter-weight, aluminum-bodied 2015 Ford, and there is also talk of reducing weight for driveline components such as axles and driveshafts. These changes are all part of an attempt to meet strict new fuel economy standards coming in 2017, targets which will get even tougher in 2025.

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.

These were our favorite cars of 2022

Favorite cars is different than best cars. The idea of "best" can speak to value and overall competitiveness in a given vehicle segment. There's lots of objectivity involved and to do a "best" list right, one really must be very thorough and as scientific as possible. This is not that list. This is about our favorites, so objectivity be damned. If we liked a Challenger Hellcat because it made loud noises or a Honda Odyssey because it made for a particularly special family vacation, fair game. These were the cars that most spoke to our collection of editors and the ones that stayed in our minds and hung in our hearts long after they left our driveway. — Senior Editor James Riswick 2022 GMC Hummer EV Senior Editor, Green, John Beltz Snyder: I didn't particularly expect to like the new Hummer. I wasn't a fan of the Hummer H2 or H3, so I wasn't automatically enthusiastic about this electric reboot. Fast EVs aren't hard to come by — and, in fact, may be too easy to come by — so its performance specs weren't enough to win me over. Despite videos to the contrary, pickups aren't my favorite vehicular format. And its excessive size and weight turned me off ... until I finally got behind the wheel.  This thing is wildly entertaining to drive. Watts to Freedom launch control is a neat party trick, sure, but the novelty wears off quickly. The novelty of Crab Walk, however, has staying power. The rear-wheel steering makes this behemoth feel much smaller than it is — the maneuverability is incredible, and useful. The air suspension provides tons of clearance, including a ridiculously high-riding Extract mode. I can't wait for lesser versions of the Hummer to make their way to market. Give me less power (for less money), but keep the off-road tricks onboard, and I'll be a happy camper. Senior Editor, Consumer, Jeremy Korzeniewski: If I could afford to put one of these in my driveway, I would. Sadly, I can't, so I won't (What's that, Janet? I got the lyric wrong?). Still, I love the dumb thing. Thankfully, I have another choice down below. 2022 Porsche 911 GT3 Associate Editor Byron Hurd: Yeah, duh, Porsches are good. But there's good, and then there's GT3. This is the feeling every performance-oriented RWD tuner is trying to replicate. This is hard, precise, surgical and immensely satisfying. To begin to explore this car on a public road is by itself an admission that you believe yourself to be above the rules as they apply to normal drivers.
