overall
Summary
With 194 currently listed for sale and an average price of $25,207.00, 33.5% of 2020 Cadillac CT4s for sale on CarGurus are rated as good or great deals.
Favorably reviewed: Owners rated the 2020 Cadillac CT4 4 / 5 stars.
77.3% of 2020 CT4 models on CarGurus are accident free.
The 2020 Cadillac CT4 features a turbocharged 2.0-liter four-cylinder engine, offering a balance of performance and efficiency, along with a modern infotainment system that enhances the driving experience.
Why it stands out
The 2020 Cadillac CT4 distinguishes itself in the compact luxury sedan market with its blend of sporty performance and advanced technology. Built on the same platform as the Chevrolet Camaro, the CT4 offers a turbocharged 2.0-liter engine that produces 237 horsepower, providing a spirited driving experience. The vehicle's design is a modern take on Cadillac's styling, featuring a restyled exterior that, while distinctive, may not appeal to everyone due to its rear design. Inside, the CT4 boasts a significantly improved cabin over its predecessor, the ATS, with high-quality materials and a user-friendly infotainment system that includes standard Apple CarPlay and Android Auto. However, the CT4 does have its drawbacks, such as a lack of standard advanced safety features and a somewhat noisy engine that detracts from the overall luxury experience. Despite these limitations, the CT4 remains an appealing option for buyers seeking a sporty yet affordable entry-level luxury sedan.

Reviewed a 2020 Cadillac CT4 on Mar 13, 2022
The Cadillac CT4 Premiere Luxury is well appointed for the price point of the vehicle. The interior is more luxurious than other luxury vehicles I considered in my search. The Acura TLX A-spec is a beautiful car on the outside, however does not look like a luxury car on the inside. For a 4 cylinder with turbo, the car responds like a V6 with plenty of get up and go. I would definitely recommend this vehicle.

Looks great. Rides great. But no safety rating. Car came out in 2019. Still no safety rating. Why?
