This is the end of the line for the Cadillac CT4, whose production ends in June 2026. For its final run, this pleasant-to-drive, well-finished, but somewhat cramped subcompact luxury sedan offers three engine options. The turbocharged 2.0-litre four-cylinder engine produces 237 horsepower, the optional 2.7-litre unit develops 310 horsepower (325 in the CT4-V), and the twin-turbo 3.6-litre V6 cranks out 472 horsepower in the mighty CT4-V Blackwing. The latter can be specified with a manual transmission.
