I've been driving for quite a while and often pay attention to Cadillac models. The ATS is the standard version with a shorter wheelbase, making it more agile to handle. The steering wheel responds quickly when cornering, which is great for those who love fast driving, but the rear legroom might feel a bit cramped. The ATS-L is the extended version, with a wheelbase increased by about 85mm, making the rear noticeably more spacious. It’s much more comfortable for a family, though it feels slightly heavier and less nimble to drive. The ATS-L is mainly sold in the Chinese market, catering to the local preference for larger spaces, while it’s less common in the U.S. There’s not much difference in the engines—both offer a 2.0T or V6 option—and maintenance is pretty much the same. I didn’t even notice any difference when changing tires. So, which one to choose depends on your needs: go for the ATS if you prioritize sportiness, or pick the ATS-L if comfort is your focus. Both new and used cars are quite affordable now, so it’s best to take a test drive before deciding.

I think the biggest differences between the Cadillac ATS and ATS-L lie in space and positioning. The ATS was designed with a standard wheelbase, offering a sporty driving feel, but taller passengers may find their knees pressing against the front seats in the rear. The ATS-L, however, features a specially extended wheelbase—I’ve tried it, and there’s enough legroom to stretch out, making it more comfortable for family trips or picking up clients, ideal for daily family use. The ATS-L is primarily sold in Asia, especially common in China, with slightly discounted pricing and no major changes to the engine tuning. The chassis is largely the same, though the extended version offers slightly better stability, particularly on wet highways. Fuel consumption is nearly identical, around 10L/100km. Both cars look sleek, with the ATS being a bit more compact. In short, if you frequently carry passengers, the ATS-L is the better choice; otherwise, the ATS offers better value. Don’t be confused by the names—maintenance parts are interchangeable. I’d recommend checking owner forums before making a decision.

Simply put, the Cadillac ATS has standard dimensions and excellent handling; the ATS-L features an extended wheelbase, offering more rear legroom. The ATS-L sells more in China, sharing the same chassis structure but with a longer body for easier driving. They have similar configurations and no difference in maintenance.

The core differences between the ATS and ATSL lie in wheelbase length and target markets. The ATS has a standard wheelbase, offering agile handling; the ATSL's wheelbase is extended by approximately 8 cm, providing more rear legroom—I've tested it with friends, and it feels more comfortable. The ATSL is a China-specific model tailored to local preferences, sharing the same chassis and powertrain with minor tuning differences. Prices are similar, but the ATSL holds its value better in the used car market. The extended wheelbase has minimal impact—for example, acceleration times are nearly identical, though the ATS feels sharper in tight corners. Maintenance costs are the same, and even engine oil compatibility is identical. Cadillac designed this to cater to regional tastes, similar to BMW's 3 Series and its long-wheelbase variant. Overall, choose the ATSL for space priority or the ATS for driving fun. Always check the spec sheet for details before purchasing.
