Dead: Cadillac CT4, CT5

Cadillac and General Motors have confirmed the Cadillac CT4 and CT5 sedans will go to car heaven/the junkyard in the sky after the 2026 model year.

What, you ask, clutching tightly to whatever buff book you have on hand, will happen to the Blackwing? Oh god, no, the manuals! Save the manuals!

Well, as NFL quarterback and psychedelic substance enthusiast Aaron Rodgers once said, relax.


According to our friends in Ann Arbor over at Car and Driver, the CT5 will return soon. Or, at least, as Cadillac brass put it in a letter to a CT fan Web site: "the legacy of the CT5 will continue with a next-generation ICE vehicle."

That, to me, suggests a sedan or something like it, though the nomenclature could change. Those among you who resist electrification will note the magic acronym, one that in this context means "internal combustion engine" and not "controversial law enforcement agency tear-gassing cities for no reason."

So yeah, whatever replaces the CT5 will have a gas engine. Displacement, cylinder count, and use of forced induction are not known, but C/D notes that GM announced the development of a new V8, slated for the Tonawanda plant, back in May.

That engine is supposedly meant for jumbo luxo-barge SUVs, but it likely would be easy to tweak to fit into a future CT5 Blackwing. We wouldn't rule out six-cylinder power, either, especially with forced induction, but we're just speculating wildly now. Figure a four-banger and/or a V6 for non-performance models. Maybe with forced air, maybe not.

The bad news is that there's no news on a manual -- would Cadillac use a six-speed unit in these automatic-heavy times? After all, the Corvette no longer offers three pedals and the Camaro is pining for the fjords. Is Cadillac, the brand associated with bloated luxury cruisers that are bedecked with chrome, the "save the manuals" standard-bearer for the General? At least for now?

We won't know for a while.

The CT5 replacement will be built at the same Lansing Grand River Assembly Plant in Michigan as the outgoing models. Speaking of which, if you want a CT4, production is slated to end in June 2026, while the CT5 will be built until "late" 2026.

Tim Healey grew up around the auto-parts business and has always had a love for cars — his parents joke his first word was “‘Vette”. Despite this, he wanted to pursue a career in sports writing but he ended up falling semi-accidentally into the automotive-journalism industry, first at Consumer Guide Automotive and later at Web2Carz.com. He also worked as an industry analyst at Mintel Group and freelanced for About.com, CarFax, Vehix.com, High Gear Media, Torque News, FutureCar.com, Cars.com, among others, and of course Vertical Scope sites such as AutoGuide.com, Off-Road.com, and HybridCars.com. He’s an urbanite and as such, doesn’t need a daily driver, but if he had one, it would be compact, sporty, and have a manual transmission.

    'Well, as NFL quarterback and psychedelic substance enthusiast Aaron Rodgers once said, relax.'

    'psychedelic substance enthusiast' sounds civilized compared to 'psychedelic substance abuser'. Well said.

    The phrase "for no reason" does not mean what you think it means.


    You can stop with the hysterics and contrived panic. Most Americans 'came from' a Maternity or Obstetrics unit of a hospital. Which means that were ICE try to deport them back to where they came from, those hospitals would suddenly have several thousands of former newborns crowding the waiting rooms and into the parking lots.


  • Peeryog Everytime I see one I am reminded of the current Santa Fe. And vice versa.
  • Original Guy I watched that Moscow parade thing. (With the Cyrillic captions because my Russian is a little rough.) I won't give the whole thing away, but it started off with a couple of dudes riding around in stupid useless convertibles, standing up like Hitler, who I'm pretty sure was an actual Nazi. They drove around in circles and kept stopping to ask if anyone had seen all the missing military equipment, and all the guys kept moaning back, that no, they hadn't, ask the next section of guys.They looked around for someone shorter and sicker-looking than Putin but they were unsuccessful so they let him speak.The North Korean military was there, I guess the invasion has begun. The North Korean guys were skinny but their rifles were nicely polished, I guess they have plenty of time on their hands between meals.Some of the Russian military guys carried little white flags, I assume they keep those handy in case they run across any U.S. Marines.
  • Marc J Rauch EBFlexing on ur mom - Ethanol is compatible with more types of rubber, plastic, and metal than gasoline and aromatics. This means that ethanol is less corrosive. The bottom line is that long before ethanol could have any damaging effect on any engine component, gasoline and aromatics would have already damaged the components. And the addition of ethanol doesn't exacerbate the problems caused by gasoline and aromatics; it actually helps mitigate them.
  • Original Guy Today I learned that a reverse brake bleeder (and a long borescope) can be helpful if you are autistic and don't have any friends and no one wants to work with you to bleed your brakes. Also it is quick, once you figure out the process.When Canada assembled my truck back in circa 1995, they apparently used a different clip to attach the brake pedal (and switch) to the brake booster than what is technically called for. It is tough to realize this when the spring steel clip flies off to who knows where. Of course I ordered the wrong clip trying to match the style that I saw buried up in the dash before it flew away. My truck now has the 'correct' clip, everyone can relax.I ordered some more brake fluid (DOT 3, nothing fancy) but it turns out I still have two fresh bottles (my shelves aren't empty, I just have too many shelves).Went to install my fancy new Optima YellowTop battery and it turns out I need a new side post terminal bolt. (Yet another order placed, bring on THE TARIFFS.) It would be a shame to strip out the threads on a nice new battery, no?Good news: The longer it takes me to get my truck started again, the more I save on fuel. 😁
