    GM’s Nervous System that Enables Future Technology Adoption

      Software is the Next Battleground in the auto war and GM is ready to win it with a new electrical platform.

     General Motors has developed an all-new digital vehicle platform necessary for its next-generation of vehicles, EVs, active safety, infotainment and connectivity features, and the evolution of the Super Cruise driver assistance feature.” To quote their press release.

    We have heard that GM has their next EV platform that will cover multiple new auto’s and that GM has their global ICE auto platform. The one thing that no one has talked about is the nervous system that is underneath these new autos.

    Tesla has proven that technology can sell and that the younger generation is wanting an auto to stay current much like their smartphone and yet not be a challenge to upgrade such as some OEMs have done with requiring you to come in and get them to flash the Powertrain with a USB thumb drive or the NAV system with a new expensive DVD update.

    GM has their mission and vision for a world with zero crashes, zero emissions and zero congestion. To achieve this in both auto’s meant GM needed a new electronic platform.


    The 2020 Cadillac CT5 will be the start of the Generals 3 year roll out to have all GM built global autos on a single new powerful electric platform. This new platform is not a thing that dealerships will be selling as most people will not care about the fact that starting with the CT5 this car will be capable of processing 4.5 Terabytes of data per hour, a five-fold increase over GM’s current electrical architecture. Depending on the system in the auto, every auto will have 100Mbs, 1Gbps and 10Gbps ethernet connections both internally and externally.

    With this new electric platform, GM has also built in an encrypted Cybersecurity as a key pillar of this new architecture. The Cybersecurity has multiple protective features at both hardware and software levels reflecting GM’s push for safe and secure autos.

    GM is among the first automakers with a dedicated and integrated Product Cybersecurity organization. This group is focused on insuring that every new auto GM puts out will be protected against unauthorized access to the vehicle and customer data.

    GM is also chairing the Auto-ISAC (Automotive Information Sharing & Analysis Center), a public and private-sector of partners that share and analyzes intelligence about emerging cybersecurity risks for the auto industry.

    GM like the Smartphone industry will make standard all software updates for their auto’s over the air enabling adoption of functionality upgrades throughout the lifespan of the vehicle with no need to come to the dealership to get them.

    GM autos will have a new Nervous system, a new electric system that for some would could cause concern that things would get overly complicated. This is where GM empowered the new engineering team to think outside the box and clean sheet what it would take to for the long future road of auto tech.

    According to the magazine Wired, after GM press announcement on their new electric platform, GM’s director of electrical components and subsystems Al Adams talked with Wired. Mr. Adams says this is the little-appreciated, tucked-away guts of an auto that is not noticed till it does not work. This new electrical system will roll out over the next 36 months to standardize GM’s 56 models across four brands

    Mr. Adams says this is equal to having an original iPhone and trading it in for an iPhone 7 in terms of the power it will add to the autos.  This will allow a standardization of Super Cruise and other safety features to be rolled out throughout the whole global product lines.


    The biggest benefit that Mr. Adams says this will do is to simplify the auto’s which today have 30 to 40 separate computers controlling a wide range of feature / functions. This is double what it was only 10 years ago. This new electronic platform will bring it back to a single enterprise multi-core computer running the whole auto. This new platform ended up reducing the amount of multiple wire strands being run reducing a noticeable amount of weight in the autos.

    300 electrical engineers and computer scientist filed more than 100 patents and benchmarked the new auto cybersecurity system against defense and aviation systems with a focus on message authentication. This allows the cruise control system to know that the radar is really talking to it when it says the road is clear ahead and not some external source. Millions of miles of testing have gone into this new robust platform to ensure that the auto’s being built will last for decades through any type of weather.

    To quote Mr. Adams, “Software is the Next Battleground!” in the auto war.

    Wow. Sounds great.  It is all in the execution though, so good luck with that.

    Agree, this is one time that GM needs to deliver on all fronts as a broadband strong electrical system would do wonders for all the auto's and the interface of the nav system working with your latest Android or Apple phone.

    Seems GM is finally delivering their new Nervous system by starting with the Cadillac 2021 Models of the CT4, CT5 and Escalade.

    Cannot wait for this to get spread throughout the whole GM portfolio with over air updates.

    • I would have never thought that until it went FWD.  Thank you.  So, even when RWD, it was an X body. I vaguely remember all the FWDs GMs on this chassis had 2.5L Iron Dukes and the rudimentary 2.8 V6s, if I'm not mistaken.  Neither engine was in it for the long haul, with each plagued by expensive issues after time.  What a difference a year could make.  If you got the '77 model with a 231 c.i., you got an "odd firing" one.  If you got next year's model, you got an "even firing" one.  I have no idea what the longevity of carbureted 231 c.i. engines of that decade was.  I had one in the '80s and it surpassed 170,000 miles, only coughing up a timing chain along the way.  With it being a non-interference engine, the valvetrain suffered no damage.
    • Well, the stock Pirelli P-Zero Neros are finally gone.  I kept the two good ones so I can hopefully sell them to some poor sucker(s) that needs them for a lease return.  I was able to get a set of four tires installed with warranty for less than it would have cost me to replace the two Pirelli's with sidewall bubbles, one of which was bad and the other of which was very bad. I always said I would not buy Chinese tires but I did it anyway.  My only excuse = Lease.  I will say even though they were very cheap, they had surprisingly good reviews.  They are Nankang NS-25's.  My impression after two days with them:  much quieter than the 24k mile Pirelli's that had started to get quite loud before 15K miles, seem to handle at least as well on dry pavement and due to the softer sidewalls of a non-run flat they also seem to take the bumps much better.  Only downside so far seems to be that they tramline much more.  First drive on the grooved cement interstate had the car squirming around following the grooves.  Not severe or concerning but definitely noticeable.  It will be interesting to see how they do in rain and snow.
    • The old L03 305 is now out.  Threw a cam and springs in the LS1 and it is now ready to go in.  My torque converter finally arrived a couple of days ago after a 6 week wait.  It will be interesting to see how long the trans and/or rear end last.  My budget is already blown so no money for upgrades this year unless I can find a used 28 spline 3.42 rear out of a 1990-92 F-body.
    • The van is in good shape now.  The replacement radio still hasn't come in due to the COVID shutdowns putting them behind but the only thing that doesn't work is the nav and since it has Android Auto, we just use that when necessary. Only possible after effect of the crash is it seems to make a lot of tire noise now.  It had the winter tires on it when it was hit and they replaced both driver side as well as the passenger front since the van was pushed up a curb when hit.  The factory tires are the ones that are loud and I don't recall them being loud when we removed them in the fall.  Either there is a bad wheel bearing or two or the noisy tires were on the rear of the car and not as noticeable until I rotate them to the front.  Too much tread left to replace them, though.  I'll have the dealership check the wheel bearings whenever I get to take it back in for the Radio swap. After several COVID induced reschedules, the court case is finally being heard next week via teleconference.
    • According to the '77 brochure, the Phoenix had the 231 V6 standard, and the Iron Duke 151, the 305 V8 and 350 V8 as options. Also standard was a 3-spd manual on the column, with a 3 on the floor and a THM optional.
