Is the ATSL replaced by CT4 or CT5?

The ATSL is replaced by the CT4. The Cadillac CT4 is an American sports sedan. Taking the 2021 Cadillac CT4 as an example, it belongs to the midsize car category with the following dimensions: length 4760mm, width 1815mm, height 1421mm, wheelbase 2775mm, fuel tank capacity 66L, and curb weight 1535kg. The 2021 Cadillac CT4 features a MacPherson strut front suspension and a multi-link independent rear suspension. It is equipped with a 2.0L turbocharged engine delivering a maximum horsepower of 237PS, maximum power of 174kW, and maximum torque of 350Nm, paired with an 8-speed automatic transmission.

When I last changed cars, I specifically researched the successor to the ATS-L and found the CT4 to be a better fit. The CT4 retains the essence of the ATS with its compact size, rear-wheel-drive layout for agile handling, and a peppy 2.0T engine for quick acceleration. While the CT5 is more modern, its larger body makes it heavier and less suitable for city driving. I test-drove the CT4—its steering is precise, fuel efficiency is well-managed, and it’s very comfortable for daily commutes. Cadillac has stratified the CT series: the CT4 targets sporty hot hatch fans, while the CT5 aims at the premium business crowd. If you prefer a smaller car with quick responses, the CT4 directly succeeds the ATS-L, and its current price is also more affordable than the CT5.

For ATS-L owners looking to upgrade, the CT4 is definitely the right choice. The CT4 follows the same lightweight approach as the ATS, offering a similar sense of space inside and delivering stable yet agile performance on the highway. The CT5 is more luxurious but significantly larger, which I find a bit excessive. When I was changing cars, I compared both—the CT4 has lower maintenance costs, higher parts commonality, and fuel efficiency improved by over 10%. In Cadillac's brand strategy, the CT4 serves as the entry-level benchmark, while the CT5 is a flagship transition. Simply put, if you want an authentic daily driver, the CT4 is the smart choice—don’t be fooled by the CT5’s flashiness.
