Cadillac CT4 and CT5 Discontinued: What Sedan Shoppers Should Know
With the CT4 and CT5 discontinued for 2027, Cadillac's sedan lineup is in the midst of a major transition. The good news for enthusiasts is that the CT5 is expected to return in a new generation, and even more encouraging news is on the horizon for the high-performance Blackwing.
Key Takeaways:
- Cadillac discontinued the CT4 and CT5 after 2026. There is no direct replacement for the smaller CT4.
- Cadillac will bring back a gas-powered successor to the CT5, although its final name and engine options haven't been confirmed.
- Cadillac's future sedan lineup includes the all-electric 2027 Celestiq, while a new CT5-V Blackwing is reportedly in development.
Why Did Cadillac Discontinue the CT4 and CT5?
Both sedans had been part of Cadillac's lineup for several years, and their current generations were approaching the end of their production cycles. Cadillac ended CT4 production in June 2026; the CT5 ended its run in late 2026.
The company hasn't announced a direct successor to the CT4. The CT5, however, has a different future. Cadillac confirmed that its legacy would continue with a next-generation gas vehicle. It will be manufactured at GM's Lansing Grand River Assembly plant in Michigan, the same facility that produced the outgoing CT4 and CT5.
What Can Buyers Expect From the Next-Generation CT5?
Cadillac hasn't released full specifications for the upcoming model, and even the CT5 name isn't guaranteed to return. The new vehicle is expected to use an updated version of GM's Alpha platform, which could also support a future Chevy Camaro or Buick sedan.
Engine choices are still unknown. The outgoing CT5 offered a turbocharged 2.0-liter four-cylinder, and a V6 was available in certain configurations. Cadillac could continue offering similar powertrains, but nothing has been confirmed.
Will Cadillac Bring Back the CT5-V Blackwing?
Car and Driver states that a successor to the CT5-V Blackwing is also on the way. What Cadillac has planned for its successor is still uncertain. One possibility is GM's new 6.7-liter LS6 V8, introduced for the 2027 Chevrolet Corvette Stingray and Grand Sport, although the company hasn't announced anything yet.
What Other Cadillac Sedans Can You Find at Reliable?
The 2027 Cadillac Celestiq represents a different approach to the traditional luxury sedan. This handcrafted, all-electric flagship features an emphasis on personalization, with buyers able to select materials, finishes, and other details to create a vehicle tailored to their preferences.
Unlike the CT4 and CT5, which appealed to buyers looking for sport sedan performance at a wider range of prices, the Celestiq occupies the highest end of Cadillac's lineup.
For drivers who prefer a gas-powered (and less expensive) Cadillac, the outgoing CT5 and CT5-V Blackwing may still be worth exploring through remaining inventory or pre-owned availability. (And we do have them in stock.)
