Cadillac CT4 Expert Review
- The CT4 is a new model for 2020
- New 2.7-liter turbo-four for the CT4-V
The CT4 is part of Cadillac's new sedan lineup, with the CT4 replacing the ATS and the larger CT5 stepping in for the CTS. Both cars ride on the second-gen GM Alpha platform and are RWD-based but offer AWD on all trims. These new models also reposition the V-Series branding. With the CT4-V being powered by a 325-hp four-cylinder rather than the ATS-V's 464-hp twin-turbo V-6, Cadillac can compete with models like the BMW M340i and the new Audi S4, while leaving room for an ultimate performance model above the V-Series.
Both engines offered under the CT4's hood are turbocharged four-cylinders. The entry-level lump is a 2.0-liter turbo-four that develops 237 hp and 258 lb-ft of torque and is mated with an eight-speed automatic to drive the rears or all four wheels. Cadillac hasn't released performance estimates but a larger CT5 with the same engine and RWD took 7.1 seconds to hustle to 60. The engine is EPA-rated at 23/32-34 mpg city/highway, with RWD cars holding a slight highway efficiency advantage.
The Premium Luxury and CT4-V variants are available with two versions of a 2.7-liter turbocharged four-banger, with different power ratings. Unlike the 2.0-liter, the 2.7-liter engine is paired with a 10-speed automatic. In the Premium Luxury, it generates 309 hp and 348 lb-ft, but in the CT4-V, it makes an impressive (for a four-cylinder) 325 hp and 380 lb-ft of torque. These 2.7-liter models return 20/28-30 mpg.
The CT4 hasn't yet been tested by the IIHS or NHTSA, but it is available with a smattering of active safety tech. Auto emergency braking with pedestrian detection, forward collision alert, safety alert seat (which buzzes your bottom instead of beeping at you), and rear park assist are standard on Premium Luxury models and above. Those models are also available with the optional Driver Assist and Driver Awareness Plus packages, which add adaptive cruise control, upgraded emergency braking and reverse auto braking, lane keep assist, blind-spot monitoring, rear cross-traffic alert, and auto high beams.
The Cadillac CT4 seats five, but back seat legroom is especially tight. Those up front can stretch out in 42.4 inches of room, but folks sitting in back make do with just 33.4 inches. Cargo volume is limited as well. With just 10.7 cubic feet of capacity in the trunk, the CT4 is embarrassed by a similarly sized car like the BMW 3 Series that has 17.0 cubic feet.
Although we've complained about the inconsistent haptic touch buttons and slow responses of the Cadillac User Experience infotainment system (CUE) in the past, the modern iteration is much improved. There are hard buttons for frequently used controls, an actual volume knob, and it's significantly more responsive.
Every CT4 has an 8.0-inch touchscreen with Apple CarPlay and Android Auto compatibility as standard, plus Wi-Fi hotspot capability. Eight-speaker audio is standard, though a 14-speaker Bose system is optional on most models and included on the CT4-V.
2020 Cadillac CT4 Luxury
The entry-level CT4 Luxury is exclusively offered with the 2.0-liter turbo-four and eight-speed automatic. RWD is standard, and AWD is optional on all models. The Luxury trim also includes 17-inch silver-color alloy wheels, LED headlights and taillights, heated body-color side mirrors with integrated turn signals, and remote start. Dual-zone climate control is also standard, as well as 12-way driver and 10-way passenger seats, leatherette seating, a leather-wrapped steering wheel, and an 8.0-inch touchscreen infotainment system with Apple CarPlay and Android Auto compatibility and a Wi-Fi hotspot.
2020 Cadillac CT4 Premium Luxury
Premium Luxury adds desirable convenience features and gives buyers the option of choosing the available 2.7-liter turbo-four and 10-speed automatic. Regardless of engine, Premium Luxury models feature 18-inch silver-painted wheels, auto on/off headlights, rain-sensing wipers, and an auto-dimming rearview mirror. It's dressed up inside with leather upholstery, driver's seat memory settings, 14-way front seats and safety alert driver's seat, and ambient interior lighting. Auto emergency braking with pedestrian detection and rear park assist are both included.
2020 Cadillac CT4 Sport
The CT4 Sport loses the 2.7-liter engine option but gains 18-inch nickel-color alloy wheels, Brembo performance front brakes, black side skirts, black window surround, a body-color rear spoiler, tinted taillight lenses, 18-way front seats with extendable thigh bolstering, and a sport steering wheel with magnesium paddle shifters.
2020 Cadillac CT4-V
The CT4-V is (for now) the most performance-focused of the lineup, boasting a high-output version of the 2.7-liter turbo four-cylinder, magnetic adaptive suspension, performance-tuned traction and stability control, a mechanical limited-slip differential, and launch control. It also gets quad-outlet exhaust, run-flat summer tires, a standard rotary infotainment controller, Bose 14-speaker audio, and wireless charging.
