2020 GMC Sierra makes diesel and 10-speed more available

The 2020 GMC Sierra full-size pickup truck doesn't look much different than the previous model, but it brings along a number of new feature updates. Specifically, certain options are now more widely available, including some powertrain options. The model year also brings about the truck's latest towing camera and some towing app updates. We'll start with the 3.0-liter diesel inline-six and 10-speed automatic, as both are more broadly available for 2020. The diesel adds the second-lowest Elevation trim level, meaning it's available in every trim except the base Sierra. The diesel is also now an option for the CarbonPro Edition AT4 and Denali, so you aren't limited to the 6.2-liter V8 for those trims. The 10-speed automatic is finally available on the 5.3-liter V8, but it's restricted to four-wheel-drive versions of the SLT, AT4 and Denali trims – lower trims retain the eight-speed automatic. The 10-speed transmission continues to be standard with the 6.2-liter V8 and 3.0-liter diesel. GMC also added new towing-related features for 2020. It has a newly-optional rear-view camera system that can show what's behind the truck's trailer, and it can project that where the trailer is on the main display, effectively making the trailer disappear. This feature was introduced in the Sierra HD. GMC also added a feature to its trailer app that lets you store and share details on your trailer setup so that it's easier for someone else to hook it up. You can even monitor and activate functions on compatible trailers with the app. There are a number of other more minor updates. Sierras can now be optioned with adaptive cruise control. The Elevation trim is available with the Crew Cab configuration. The AT4 CarbonPro Edition gets a few extra black accents compared with the 2019 version. Pricing and availability of the 2020 Sierra haven't been announced yet, though.

Chevy Silverado, GMC Sierra 4.3-liter EcoTec3 V6 nets 18 mpg city, 24 highway

There is no doubting that fuel economy has become an important factor in the highly competitive fullsize truck market, with the Ford F-150 EcoBoost V6 and Pentastar V6-powered Ram 1500 setting quite a precedent in recent years. Now it's General Motors' turn. The General has just announced that the new base V6 used in the 2014 Chevrolet Silverado and GMC Sierra 1500 models will return an EPA-estimated 18 mpg city and 24 mpg highway in two-wheel drive trim, regardless of cab configuration.
While these figures don't go so far as to earn GM any "best-in-class" fuel economy claims (thanks to the 25-mpg Ram 1500 HFE), this new 4.3L EcoTec3 V6 does edge the F-150 and Toyota Tundra while boasting best-in-class numbers for torque, payload and towing capacity among six-cylinder rivals. This all-new engine produces 285 horsepower and 305 pound-feet of torque, and it gives the 2014 Silverado and Sierra the highest towing rating among standard V6 models with a 7,200-pound towing capacity - besting the Ram by 700 pounds, the base F-150 by 1,100 pounds and coming within 200 pounds of the V8-powered Nissan Titan.

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.
