Why it stands out

The 2020 Cadillac CT4 sets itself apart in the luxury sport sedan market by providing a unique blend of sporty performance and upscale features, all at a relatively affordable price. Its standard turbocharged 2.0-liter engine offers adequate power for most driving scenarios, while the option of rear-wheel or all-wheel drive enhances its appeal for enthusiasts. The CT4 showcases an improved interior compared to its predecessor, the ATS, with upgraded materials and a more user-friendly infotainment system, featuring an 8.0-inch touchscreen and standard smartphone connectivity. The car's driving dynamics are tailored for sporty handling, and despite some noted noise issues from the engine, it delivers a fun driving experience, especially on highways. However, potential buyers should be aware of the absence of standard advanced safety features, which may detract from its overall value proposition.
