Quick summary
- The XT4 has no release date because it was retired; 2025 is the last model year the EPA rated.
- Cadillac drops two petrol crossovers at once, since the three-row XT6 leaves at the same time.
- An electric Optiq now occupies the size and price bracket the XT4 used to hold.
Short answer: there is no release date for a new Cadillac XT4 because Cadillac has stopped building it. The EPA rated the XT4 through the 2025 model year and lists none for 2026, and the same is true of the XT6. What arrives in their place is electric: the Optiq and the Vistiq. The petrol XT5 does carry over, which settles a point reporting had disagreed on.
Is there a new Cadillac XT4 coming?
No. The EPA rates every vehicle sold new in the US, and its list carries XT4 FWD and XT4 AWD for 2025 and nothing for 2026. GM Authority reported production winding down in early 2025, and the rating list is now the confirmation: once a nameplate drops off, there is no new car to buy under it.
That is worth saying plainly because “release date” searches assume a next one exists. Here the honest answer is that the question has no date attached to it, only a successor with a different name and a different powertrain.
What the last XT4 was
A compact luxury crossover with a single engine across the range: a 2.0-liter turbocharged four driving through a nine-speed automatic, in front- or all-wheel drive. Unlike the mainstream crossovers it competed against, it asked for premium fuel, which on a turbocharged engine is about holding off knock rather than adding power — the distinction our octane guide sets out.
| Version | Engine | City / Highway / Combined | Fuel |
|---|---|---|---|
| XT4 FWD | 2.0-liter turbo four, 9-speed auto | 24 / 29 / 26 mpg | premium |
| XT4 AWD | 2.0-liter turbo four, 9-speed auto | 23 / 28 / 25 mpg | premium |
One mpg separates the two, so all-wheel drive costs very little here by the usual standards. The 2024 and 2025 cars carry identical ratings, which means a late used example gives up nothing on paper to the final one.
What replaced it?
The Optiq, an electric crossover that sits where the XT4 did. Cadillac is making the same swap one size up, where the three-row Vistiq takes over from the XT6; both newcomers appear on the 2026 rating list, and neither XT4 nor XT6 does.
The XT5 is the exception, and it is where published reporting had split: one outlet had it leaving after 2025 alongside the XT6, others had production running to the end of 2026. The EPA list answers it directly — XT5 AWD and XT5 FWD are both rated for 2026, so it stayed. When sources disagree about whether a car is still sold, the rating list is usually faster to check than any of them.
What Cadillac’s 2026 range looks like
Thin on petrol crossovers and heavy on electric ones. Among SUVs the rated 2026 cars are the XT5, the Escalade and Escalade V, and then the electric Lyriq, Optiq and Vistiq; the saloons are the CT4 and CT5 with their V versions, plus the Celestiq. Two of the three petrol XT models that existed in 2025 are gone from it.
If you were shopping an XT4 because of its size, the Optiq is the direct answer but changes the fuel question entirely. If the petrol engine was the point, the XT5 is now the only Cadillac crossover below Escalade money that still has one — and for a sense of where the brand is heading instead, our look at the Escalade IQ covers the electric end of the lineup.
Cadillac is not alone in quietly closing a line and leaving the searches behind; we ran the same check on the Jeep Renegade, which left American showrooms two model years earlier and still turns up in listings under years nobody built.
