2021 Cadillac CT4 MODEL OVERVIEW

Pros

  • Rear-drive chassis balance
  • Good ride quality
  • Strong 2.7T engine

Cons

  • Limited cargo space
  • Tight back seat
  • Early builds of the 2021 CT4 won't have Super Cruise

Serving as Cadillac's entry-level sedan, the subcompact CT4 is positioned below the CT5 and the outgoing CT6. Available with RWD or AWD and a range of four-cylinder engines, Cadillac is casting a wide net for potential buyers. The CT4 competes with other small luxury sedans including the Audi A3, BMW 2 Series Gran Coupe, and Mercedes-Benz A-Class.

What's New

  • Diamond Sky Special Edition
  • Wireless Apple CarPlay and Android Auto
  • Enhanced Super Cruise available for CT4 Premium Luxury and CT4-V in early 2021
  • Automatic emergency braking with pedestrian detection now standard

What We Think

When we got behind the wheel of an AWD CT4-V, we found Cadillac produced a proper small sport sedan. The 2.7T powerplant we previously experienced in the Chevrolet Silverado pickup feels gutsy and strong in this application, providing ample acceleration and impressive refinement. The CT4 also offers a rear-drive chassis with balance outshining that of the CT4's FWD-based competition. Ride quality is a strong point as well, earning the Caddy serious points in a comparison against the Mercedes-AMG CLA 45, although the Benz makes for a better sport compact.

Performance and Fuel Economy

The CT4 is offered with two different turbocharged four-cylinder powerplants. CT4 Luxury and CT4 Sport models are exclusively available with a 2.0-liter turbo-four cranking out 237 hp and 258 lb-ft of torque. That engine is paired with an eight-speed automatic sending power to just the rear wheels (RWD) or all four (AWD). With the smaller engine, the CT4 is EPA-rated at 23/32-34 mpg city/highway depending on the drive type.

A 2.7-liter turbo-four is an optional upgrade on Premium Luxury models and standard on the CT4-V. It's offered in two states of tune: a 310-hp/350-lb-ft version in Premium Luxury models and a hotter 325-hp/380-lb-ft tune for the CT4-V. In either case, the 2.7-liter turbo-four is mated to a 10-speed automatic for RWD or AWD. All CT4s with the big four-banger are rated for 20 mpg city, but highway mileage ranges from 28-30 mpg. When we street-tested an AWD CT4-V, it reached 60 mph in 5.1 seconds; the RWD variant did the deed in 5.5 seconds.

Cadillac CT4 Blackwing vs. CT4-V

Remember the ATS-V? The twin-turbo six-cylinder athletic all-star version of the CT4's predecessor? Oddly enough, the CT4-V does not replace that car. No, the top dog configuration of the CT4 will be dubbed the CT4-V Blackwing, alluding to the darkly colored birds on the old Cadillac crest. That car will be powered by an upgraded version of the ATS-V's V-6, now making 472 hp and 445 lb-ft of torque.

Safety

Budget-minded shoppers will be happy to hear Cadillac has made automatic emergency braking with pedestrian detection standard on all models. Available Driver Assist and Driver Awareness Plus packages add adaptive cruise control, lane keep assist, blind-spot monitoring, rear cross-traffic alert, and automatic high beams.

Cargo Space and Interior Room

All CT4s seat five passengers, but those stuck in the rear seat may feel cramped. The CT4 offers just 33.4 inches of rear legroom, compared to 35.1 inches in an Audi A3, 33.9 in a Mercedes-Benz A-Class, or 34.4 in a BMW 2 Series Gran Coupe four-door.

Cargo space tells largely the same story. At 10.7 cubic feet, the CT4's trunk is more spacious than the 8.6-cube A-Class but falls short of the 12.3 cubic feet in the A3 or the impressive 15.1 cubic feet in the trunk of the 2 Series.

Technology

Every CT4 features an 8.0-inch touchscreen infotainment system with now-wireless Apple CarPlay and Android Auto support. A 12.0-inch digital instrument cluster display is also new for 2021. This model year also adds a rotary controller for the infotainment setup. The standard audio system is an eight-speaker system, but 14-speaker Bose premium audio is optional on most models and standard on the CT4-V.
