In 2019, Cadillac unveiled the CT4 for the 2020 model year, marking a significant update to its entry-level luxury sedan lineup by replacing the ATS. This new model represented a shift in priorities, with the manufacturer placing greater emphasis on dynamic performance rather than traditional comfort features.
As a storied luxury automaker, Cadillac faced the challenge of maintaining its heritage while adapting to modern trends. The CT4 benefited from sharing its platform with the ATS, which was among Cadillac’s most capable chassis. However, beyond this foundation, the CT4 was an entirely new vehicle rather than a mere redesign.
The design team dedicated considerable effort to crafting a distinctive appearance. The vehicle’s imposing chrome grille, complemented by full LED headlights, created a commanding front-end presence. The lower bumper featured a trapezoidal central grille flanked by vertical air intakes. The profile showcased an elegant rising beltline accentuated by chrome door trim, while the greenhouse followed contemporary cab-rearward design trends. The rear end, with its sloping windshield and compact decklid, conveyed a sporty character aimed at appealing to modern consumers.
The interior was designed with a strong driver-centric focus. The dashboard and tall center console were angled toward the driver, creating a sporty, race-inspired ambiance. The instrument cluster combined traditional analog dials for the speedometer and tachometer with an LCD display for vehicle data. A centrally mounted touchscreen integrated Apple CarPlay and Android Auto functionality and served as a mobile hotspot for passengers. Front occupants enjoyed generous legroom, while the supportive seats provided excellent lateral support during dynamic driving. The rear bench was specifically profiled for two passengers due to the high transmission tunnel, although a center seatbelt was still provided.
Contrary to expectations, the CT4 did not offer V8 or V6 engine options. Instead, it was equipped with turbocharged inline-four cylinder engines. Despite this, the vehicle delivered impressive performance. The top-spec variant produced over 300 horsepower, available to either the rear wheels or all four corners through a standard 10-speed automatic transmission. Lower trim levels featured a 2.0-liter turbocharged engine paired with an 8-speed automatic transmission, proving that modern engineering could deliver both efficiency and performance.
