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.

Next Corvette ZR1 to get 700 horsepower?

Word has it General Motors may offer as much as 700 horsepower in the C7 Corvette ZR1. Motor Trend reports the next Corvette Z06 will continue to rely on its naturally aspirated 7.0-liter V8 engine for thrust, but the lump will deliver substantially more power. How much more? MT says the engine could deliver up to 600 ponies. That's a jump of 95 horsepower over the current Z06, though no figures have been finalized as of yet. Right now, GM is reportedly waiting to see what sort of grunt it can glean from the next ZR1.
The automaker has already made it clear it will resurrect the LT5 name for the new supercharged V8, and if GM is already pulling 600 from the Z06, the big dog ZR1 would theoretically offer 700 horsepower. Either way, the range-topping Corvette will be suitably insulated from its less potent siblings. Stay tuned. We aren't likely to see the Z06 for at least a year, with the ZR1 trailing along at some point there after.

GMC Canyon, Chevy Colorado diesels finally heading to dealers

Customers who have been waiting to receive their diesel-powered Chevrolet Colorados and GMC Canyons should be relived to hear that GM will finally start to ship them out of the Wentzville Assembly Plant. "The highly anticipated 2016 GMC Canyon diesel has begun shipping to dealers," a company spokesperson confirmed to The Detroit News. The trucks originally had a fall launch date, but a final review forced a delay in deliveries. The 2.8-liter four-cylinder diesel in the midsize trucks produces 181 horsepower and 369 pound-feet of torque, and the company touts the engine's low emissions. The Environmental Protection Agency and California Air Resources Board even put the mill through extra scrutiny with a real world test in the wake of VW's diesel scandal, and the Duramax passed with no problems. At that time, a Chevy spokesperson told Autoblog that the models' launch was on track. The Duramax engine adds $3,730 to the price of a comparable V6 model, but they're the most fuel-efficient pickups on the market. The EPA estimates the twins at 31 miles per gallon highway, 22 mpg city, and 25 mpg combined in two-wheel drive form and 29/20/23 with four-wheel drive. Buyers likely can't wait to finally experience these pickups after reading a heap of positive reviews. The Colorado diesel recently earned Motor Trend's Truck of the Year award. We also came away impressed with it during our First Drive and liked the Canyon during our Quick Spin. Related Video:
