As a car owner who frequently travels with family, I believe the biggest differences between the Cadillac XTS and ATS lie in space and comfort. The XTS has an oversized body, with a rear seat spacious enough for three adults without feeling cramped, and a trunk that can fit several large suitcases. During long trips, my family can sleep comfortably, and the soft suspension tuning makes driving over bumps feel like sitting on a sofa. In contrast, the ATS is much smaller in space, with limited legroom in the rear, making it more suitable for singles or young couples for daily commuting. Performance-wise, the ATS offers precise steering and is exhilarating on mountain roads, while the XTS focuses more on stability, ensuring a comfortable ride in the city without causing motion sickness. The XTS also boasts a superior sound system, delivering a more immersive music experience. For family trips, I would definitely choose the XTS first; for solo spirited driving, the ATS is more thrilling. However, the ATS has slightly higher fuel consumption, which is something to consider carefully—don’t just focus on the excitement.

For enthusiasts accustomed to sporty models, I feel the driving experience of the ATS far surpasses that of the XTS. The ATS has a lightweight body with sharp steering, sticking to the ground during sharp turns and accelerating instantly when you step on the gas—the exhilarating push-back feeling on the highway is unmatched. Although the XTS shares the same class of engine, its tuning is more subdued, offering steady but slightly delayed acceleration, making it better suited for business commutes or long-distance travel.
In terms of interior, the ATS leans more toward a sporty feel with a snug, wrap-around seating experience, while the XTS offers a more luxurious touch with comfortable leather seats, though it feels too business-oriented when driving. Space is the ATS's weak point, as fitting luggage in the trunk can be a hassle, whereas the XTS easily accommodates family trips.
Price-wise, the ATS is more affordable at entry-level and has lower maintenance costs, making it ideal for budget-conscious young drivers. In short, choose the ATS for thrills and the XTS for stability.

From the perspectives of interior and technology, I believe the XTS is more luxurious, featuring premium leather seats and a large touchscreen, with an infotainment system that supports multi-screen connectivity. The ATS has a sporty design with practical yet simple functionalities, and its center console button layout is convenient for driving operations. Technologically, the XTS also includes adaptive cruise control and road condition alerts, with its urban collision prevention feature being very practical; the ATS leans more towards basic driving assistance. The space comparison is evident—the XTS offers a spacious back seat, suitable for resting, while the ATS has a compact rear, only comfortable for short trips. Both have strong safety systems, but the XTS adds side collision protection. Cost-wise, the ATS is more affordable, with a lower price tag and cheaper insurance; the XTS is pricier but holds its value better. In terms of driving feel, the ATS is more responsive and fun, while the XTS is smooth but dull. Overall, the XTS suits family-oriented men, whereas the ATS targets single tech enthusiasts.
