As a subcompact luxury sedan, the CT4 demonstrates Cadillac's commitment to a declining vehicle segment. The base model features a turbocharged 2.0-litre four-cylinder engine producing 237 horsepower. Further up the range, a 2.7-litre engine produces 310 horsepower, except in the sporty CT4-V which is rated at 325 horsepower. The cream of the crop is the CT4-V Blackwing, which packs a twin-turbo 3.6-litre V6 delivering 472 horsepower. It can even be fitted with a manual gearbox.
