overall
Summary
With 175 currently listed for sale and an average price of $24,510.00, 36.0% 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.
75.4% of 2020 CT4 models on CarGurus are accident free.
The 2020 Cadillac CT4 features multiple powertrain options, impressive technology, and a stylish design, though it falls short in refinement and value.
Why it stands out
The 2020 Cadillac CT4 stands out as an entry-level luxury sport sedan offering a distinctive design and engaging driving dynamics. While it utilizes a platform derived from the older ATS, the CT4 incorporates modern technology and comfort features that appeal to buyers looking for a sporty yet upscale vehicle. The availability of multiple powertrains, including a turbocharged 2.0-liter engine producing 237 horsepower, allows for a customizable driving experience. However, some critics note its underwhelming performance and lack of standard advanced safety features, which could affect its appeal against competitors like the Genesis G70. The CT4 balances its sporty aspirations with everyday usability, making it relevant in a shrinking market for sedans.

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?
