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.

Cadillac CT4 and CT4-V pricing revealed, starts just under $34,000

The Cadillac CT4-V had its big reveal in Detroit several months ago, and last month we finally saw the regular CT4. Today, Cadillac has pricing available for every CT4 trim level including the V. The entry-level CT4 Luxury with rear-wheel drive will start at $33,990, including the destination charge. Adding all-wheel drive requires another $2,600, bringing the total to $36,590. Cadillac also throws in heated front seats and a heated steering wheel when you opt for the all-wheel drive model. The CT4-V comes in at $45,490 before options — on the V, the up-charge for all-wheel drive is only $1,100. Cadillac CT4-V View 12 Photos Cadillac offers two trims in between the base Luxury and more powerful V-Series: Premium Luxury and Sport. The Premium Luxury is priced from $38,490, and the Sport is a tad bit more expensive at $39,590. All-wheel drive is even more expensive ($3,200) in the Premium Luxury, as it adds cooled front seats on top of the heated seats and steering wheel. The cooled seats arenÂ’t included with the Sport all-wheel drive package, so itÂ’s the same $2,600 charge as in the Luxury model. Every CT4 but the V comes standard with CadillacÂ’s 2.0-liter turbocharged four-cylinder that makes 237 horsepower and 258 pound-feet of torque. An 8-speed transmission handles the shifting. Go for the much more expensive CT4-V, and you get the 2.7-liter turbo four that makes 325 horsepower and a whopping 380 pound-feet of torque. This engine is exclusively mated to a 10-speed automatic. For a full rundown and background on the CT4 and CT4-V, check out our previous coverage of the cars. YouÂ’ll be able to order a 2020 CT4 later this year.

Cadillac issues stop-sale on recalled CTS, SRX

General Motors has issued a stop-sale order on the Cadillac CTS and SRX, both of which were recalled late last month. Why the stop-sale after all this time? Well, um, GM apparently doesn't know how to fix them.
The stop-sale covers all used Cadillac CTS sedans, coupes and wagons from model years 2003 to 2013, as well as new 2014 coupes and wagons. The SRX crossover stop-sale, meanwhile, only covers used vehicles from model years 2004 to 2006.
Automotive News reached out to GM spokesperson Alan Adler, who told the news pub that the company's engineers were "looking at one common solution" for the affected vehicles, although "they don't have it yet."
