The Cadillac CT4 is a compact luxury sedan built on a platform it shares with the Chevrolet Camaro. When Cadillac gave its ATS model a substantial refresh for the 2020 model year, it canceled the coupe body style and renamed the sedan CT4. It comes in CT4, CT4-V, and CT4-V Blackwing models with a choice between turbocharged four-cylinder and twin-turbocharged V6 engines, and manual or automatic transmissions. Rear-wheel drive is standard, with all-wheel drive available as an option. Cadillac is unlikely to replace the CT4 because the automaker is going electric, and its new electric vehicles (EVs) will have names ending in “iq”.
