Cadillac CT4 1st Generation

20202026 · Alpha 2 · sedan

Compact luxury sedan on GM's Alpha 2 platform (successor to the ATS). 2.0L LSY turbo I4 (237 hp) base, 2.7L L3B turbo I4 (310 hp) on CT4-V. CT4-V Blackwing (2022+) runs the 3.6L LF4 twin-turbo V6 (472 hp / 445 lb-ft) with available 6-speed Tremec manual — spiritual successor to the ATS-V. RWD or AWD. Per GM, North American production ends June 2026.

Watch out: Still relatively new but the LSY 2.0L has documented turbo wastegate-actuator failures; CT4-V Blackwing 3.6L LF4 carbon buildup on intake valves is expected long-term (direct-injection norm).

Full clubhouse — owner Garage Lineage, common problems, year-by-year notes, and product picks — is on the build list.
