The differences between Cadillac CT4 and CT5 lie in their body dimensions: The Cadillac CT4 measures 4760mm in length, 1815mm in width, and 1421mm in height, with a wheelbase of 2775mm; the CT5 measures 4924mm in length, 1883mm in width, and 1453mm in height, with a wheelbase of 2947mm. The Cadillac CT4 features a shield-shaped grille, paired with new starfall-style headlights and vertically arranged LED daytime running lights, giving its front fascia a distinctive look. The rear of the CT4 has heavy camouflage, but the vertically designed taillight clusters are still visible, with the more striking feature being the quad exhaust layout on both sides, emphasizing its performance-oriented nature.

The biggest differences between the Cadillac CT4 and CT5 lie in their size and positioning. I often drive in the city and find the CT4 more compact and agile, making parking less of a headache. It's about 4.75 meters long and offers direct handling, making it ideal for daily commutes or single individuals. The CT5, on the other hand, is larger, approaching 5 meters in length, with noticeably more spacious rear seating—it feels like a moving living room, perfect for long-distance trips or occasional joyrides with friends. In terms of pricing, the CT4 is much more affordable, with a starting price several tens of thousands lower, making it my top choice for those on a budget. The CT5 is more upscale, featuring higher-quality interior materials, such as softer and more comfortable seats. Under the hood, the CT4 emphasizes rear-wheel-drive sportiness with quick acceleration, while the CT5 offers an optional more powerful V6 engine for steadier output and easier highway overtaking. Overall, the CT4 is a toy for the young, while the CT5 leans toward maturity and stability—choosing between them ultimately depends on personal needs.

As a car enthusiast who loves performance driving, I'm particularly focused on power and handling. The CT4 has a more compact body, and its lightweight rear-wheel-drive system is incredibly responsive in corners—just step on the gas and you'll feel the exhilarating push-back sensation, making it perfect for mountain road sprints or track days. The CT5, while also sporty, has a more stable center of gravity. Its standard 2.0T engine delivers stronger power, and the optional V6 is an absolute beast, offering smoother acceleration. In terms of tuning, the CT4 has a stiffer suspension for sharper road feedback, while the CT5 is slightly softer with better vibration absorption, ideal for long-distance driving. The price difference reflects this: the base CT4 offers great value, while the CT5 adds more premium features like the Brembo braking system, which shortens stopping distances and enhances safety. Plus, the CT5 has more rear-seat space, making it less cramped for luggage on trips—something the CT4 struggles with. If you ask me, go for the CT4 if you want pure driving thrills, but if you want a balance of speed and comfort, the CT5 is the way to go.

From a practical standpoint, the dividing line between the CT4 and CT5 lies in space and positioning. I think the CT4 is more suitable for small families or couples—it's compact, easy to drive, and effortless to navigate through city streets, with parking spots being easier to find. The back seat can accommodate two adults without feeling cramped, and the trunk capacity is decent, enough for a stroller and shopping bags, though it might struggle with heavy luggage on long trips. The CT5 is noticeably larger, offering a more spacious and comfortable rear seat with extra room even after adding a child seat, along with a bigger trunk that can handle weekend family outings with ease. In terms of performance, the CT4 is sufficient without being flashy, while the CT5 delivers stronger acceleration and better stability on highways. The price difference is also a key factor—the CT4 is more budget-friendly and flexible, while the CT5 costs a bit more but offers additional comfort features. When choosing, consider your budget and daily needs: go for the compact CT4 or the midsize CT5 based on what suits you best.
