Cadillac CT4 Will Use Advanced Global B Electrical Architecture

The Cadillac CT4 compact sedan will use General Motors‘ advanced new Global B electrical architecture, GM Authority’s sister site, Cadillac Society, confirmed in a report this week.

GM first provided details on its Global B electronic architecture back in May. The new digital “nervous system”, as the automaker calls it, has much greater data processing power than GM’s outgoing electronic system and stronger connectivity.

The system will be commonplace going forward, as it will be necessary to support over-the-air updates, semi- and fully-autonomous driving functions and new advanced infotainment technologies. All future battery electric vehicles from GM will also be based around Global B.

“As the automotive industry and vehicles evolve in the next five to 10 years, more electrical bandwidth and connectivity will be needed to ensure that features like electric propulsion systems, the Super Cruise driver assistance feature and advanced active safety systems can all run in conjunction with each other,” Cadillac stated in a recent press release announcing the arrival of Global B.

The Cadillac CT4 is based around GM’s Alpha platform, which previously served in the Cadillac ATS and CTS, however it is still a much different vehicle thanks to its different smaller footprint, different exterior styling and more up-to-date powertrain offerings. Cadillac Society notes that now, with confirmation that the CT4 will also utilizes the Global B electric architecture, the CT4’s position as an all-new vehicle as opposed to a “re-skinned” ATS has been solidified even further.

The Cadillac CT4 follows in the footsteps of its larger sibling, the Cadillac CT5, in using Global B and is now the second Cadillac model to tap the new system. The 2020 Chevrolet Corvette C8 will also use the Global B architecture, as we reported previously, which is also why early, pre-production prototypes for the vehicle initially used a Cadillac key fob.

The 2020 Cadillac CT4 will go on sale later this year.

    Question ?

    Can anyone tell me if this “Global B ” system is any better than say, Tesla, Audi, Mercedes, and others ?

    Or is it just finally GM catching up again to the others already with this tech ?

      It doesn’t matter. Nothing matters relative to GM/Cadillac “catching up” because even at their most advance, their leadership has held them a solid decade behind the trailblazers

        If anyone read the piece in the NYT today on Cadillac, I think the impression is that Cadillac is as lost and clueless as ever and Steve Carlisle cannot save them. When asked why SuperCruise, the only technological advantage Cadillac has now, is available on just one model and it is likely about to be discontinued, Carlisle reportedly said “That’s just one of these unfortunate prioritization dilemmas….Had we thought of it a little earlier, we would have gotten to it sooner.” Those words don’t inspire confidence.

        It’s quite sad but I think it’s time for Mark and Mary to be looking for buyers for Cadillac. If they don’t, the brand will be Oldsmobiled by the General’s bean-counters. GM just doesn’t understand how to build luxury cars and I would rather see Cadillac sold to the Koreans than to die entirely as GM’s other mismanaged brands (Pontiac, Oldsmobile, Hummer, SAAB, and Saturn) unfortunately did.

        I think what BMW did for Rolls Royce or Tata has done for Jaguar/Land Rover would be models for what could happen with Cadillac in the hands of capable management.

          Reading between the lines of that story, the undertones state that Carlisle has no idea what he’s doing and simply was a pawn who played the game long enough to be placed in a position.

          With regards to selling to the Koreans, even with all the slander I’ve thrown, that is just blasphemy. BUT keeping in the same logic… encourage Elon to make an offer – at least the American brand stay in America and gains the electric knowledge of Tesla.

    Can’t wait for the Coupe version!!!!

    Like… I literally can not wait for it because GM hates enthusiasts and won’t make one because it’s too “niche”. Great job losing what would have been a lifelong customer Cadillac!!!

      Just get a 6th gen camaro 2.0T. Priced in the low 20’s, it’s basically an ATS coupe, but more fun, and cheap enough that you can beat on it and not care.

        Oh, I thought about that, 2SS nonetheless…. but the interior reminds you that you’re driving a Chevy and there is no getting around the stigma of “Murican Cheap Thrills” muscle car – I’m beyond that at this point in my life.

          Fair enough, but don’t deny yourself an alpha platform coupe just because it has a bow-tie on it. The interior is really well done, my 2LT trim has heated and cooled leather seats, the infotainment system is modern and works flawlessly. My friend who drives an ATS is jealous of my 2.0T camaro because it just feels so much more like a sports car. The steering is far more confident and precise on the Camaro. The ATS is built for suit-wearing types who think luxury is a floaty steering wheel. The Camaro is a hardcore sports car with no compromises. How some people attach a “stigma” to that, I have no idea. Maybe because it stands out in a parking garage full of black, white, and beige german cars that cost twice as much but are half the car?

            just read below that you tried S5, M series, and finally went for an ATS coupe. So, do you like your ATS? I’m still trying to wrap my head around your statement “GM hates enthusiasts.” The company who engineered the platform of the car you are currently driving, a platform which is universally considered to be incredibly good? Also what makes you so sure there won’t be a CT4 coupe?

    What am I missing? I’ve now read the above 5 posts and I just don’t get the same vibe from Cadillac. Why all the bashing them and saying they are so far behind BMW, MB, etc? I’ve been working with Volvo for nearly 4 years now and Cadillac is as good if not better than Volvo! And just what makes MB/BMW so good? I can personally attest to numerous clients coming in and dumping them for a Volvo after having so many electrical issues and on newer cars.

    Maybe this is the bash Cadillac day?

      For exactly what you said – which of these slogans do you think Cadillac’s marketing dept would like buy off you:

      1) Cadillac | As good as if not maybe better than a Volvo
      2) Cadillac | The car you consider when you are too old to keep up with the Germans, but end up not buying because bought a Volvo instead

      or my personal favorite

      3) Cadillac | Standard of the… third-tier luxury segment

        @Harry Manback:

        How about you tell us just why MB and BMW are better than Cadillac. What specifically is it that you feel makes them superior to the others in this department or any department for that matter?

        Sounds to me like you are just one more import snob that drives a BMW while acting like you are better than others. New flash: You’re not.

          Dan,

          My current car is a ATS Coupe, before that, I had a CTS Coupe, and before that I daily-ed a 2001 Trans Am. When It came time to replace the CTS Coupe, I test drove an Audi S5 and a BMW M240. The M240 was fun as hell to drive, had an outstanding interior, but a tad to small for me. The S5 was the best of those three cars and superior to the ATS Coupe in just about every way; primarily the build quality and driving dynamics/felt more refined. At the end, I went with the ATS Coupe for two reasons: it was a better deal (cheaper), and the brand loyalty. Mainly, I just wanted something different – I didn’t want to be “an import snob” asshat blending in with every other middle management tw-ts. When friends and coworkers would harass me for my choice of vehicle, I at least would get on my soapbox to support Cadillac and how they were on the uprise and reinventing their legacy….. but I’m having a really hard time doing that now, especially when they are making the same mistakes over and over again.

          Moreover, and on a most-personal level, as you can see from my current/previous cars, all I’ve ever driven in my adult life has been a RWD American Coupe…. yet it’s seeming like I’m not going be able to keep that trend going.

          So, what were you saying?

            It just doesn’t come across that way. From the things you were saying, it sounds like the many BMW owners that I’ve interacted with over the years. So what I would say is that maybe it’s time to move away from GM or at least from Cadillac. I’m around all types of high end brands every day. I see them all (being in LA, the snob car capital of the country) and I certainly do not view Cadillac as you and several others above seem to. But I can also say that I don’t feel Cadillac needs to be chasing after BMW/MB either. Cadillac needs to be their own brand of true luxury and not chasing the Germans.

              I’m not about the “positive reinforcement” BS – if someone is doing something wrong, you have to tell them so they can fix it, and Cadillac is doing it assbackwards wrong right now.

              If you don’t feel that Cadillac needs to be chasing zee Germans, that’s fine – Lincoln is/(isn’t) doing exactly that right now and it’s working out pretty damn well. I personally would never consider a Lincoln because I crave the performance end of luxury, and Lincoln’s current lineup lacks performance in it’s entirety. But I digress, IF that was what Cadillac’s goal was, then even there they are miles behind the 8-ball. So -going back to your original post- yeah, Cadillac is currently a good competitor to Volvo …. but is that the best a premium American luxury brand can do? Compete with a third-tier brand that many don’t even remember exists? Thus, my frustration and criticism.

    Where is the digital instrument cluster? Even a 30k VW Jetta offers a more attractive display.

    Very cool.
    I am undecided on the CT4 design to be honest. Have to wait and see it in person first.

      It looks way better in person. I’m completely sold on one after seeing it in metal.

      I can’t wait for the build & price.

    Sam — Can you explain why the interior photo accompanying your article shows a rotary control knob on the console, but in the photos of the interior taken at the May 30 unveiling of the CT4-V there is no knob?
