Why it stands out
The 2021 Cadillac CT4 is a compelling entry into the small luxury sedan market, replacing the ATS. With a rear-wheel-drive layout that offers an engaging and sporty driving experience, the CT4 rivals well-established competitors such as the Audi A3 and BMW 2 Series. Its robust chassis components, many shared with the Chevrolet Camaro, enhance both performance and handling.
The CT4 comes equipped with turbocharged four-cylinder engines, providing ample power, while the high-performance CT4-V model features a thrilling 3.6-liter twin-turbo V6. This variety makes it appealing to different types of buyers—from those seeking efficient daily drivers to enthusiasts looking for spirited performance. Notably, the CT4's technology features, including available Super Cruise semi-automated driving capabilities, elevate its appeal in a competitive segment.
While some may find the base model's performance a bit sluggish compared to its rivals, the overall package, with substantial cargo space and a well-appointed interior, provides a balance of luxury, performance, and technology that many buyers in this class will find attractive.
