The ATS extends 182.8 inches in length, while the CTS boasts the longer frame, measuring 195.5 inches long. The wheelbase dimensions also vary; the ATS has a 109.3-inch wheelbase, while the CTS has a wider stance with a 114.6-inch wheelbase. The cargo volume on the ATS is 10.4 cubic feet, while the CTS provides a bit more space for possessions, with its 13.7 cubic feet trunk.


While both base trims come with a 2-liter engine underneath the hood, the introductory version of the ATS is a bit more energetic. The ATS yields 272 horsepower , while the CTS offers four less horsepower (268). Ultimately, the CTS is your better choice for potent powertrain, especially when contrasting the highest trims. The 3.6-liter twin turbo option on the premium version of the CTS churns out 420 horsepower, while the 3.6-liter premium performance trim on the ATS achieves just 335 horsepower.

While the ATS and CTS both incorporate upscale cabin qualities characteristic of the brand, the CTS comes with more standard and available perks than the ATS. The base trim of the CTS comes with the following interior options: navigation with voice activation, 11 speakers, three 12-volt power outlets, cooled front seats, and eight-way power adjustable front seats. The CTS also has a more opulent vibe than the ATS, even at the base trim level. It boasts leather and genuine wood detailing for the steering wheel and gear shift knob, when these same features on the ATS incorporate leather and metallic materials.


The smaller ATS has a more affordable starting MSRP of $35,495, according to the manufacturer’s website. The base trim of the CTS is approximately $10K more, with a starting MSRP of $46,495.

Conclusion: If you want the most bang for your buck and don’t mind sacrificing a bit of length and cargo space, opt for the Cadillac ATS. If you desire a longer frame with a bit more engine might, more features, and a more roomy trunk, the CTS should suit.
