When searching for a Cadillac SUV that combines prestige with practicality, two models frequently come into conversation: the current-generation Cadillac XT4 and its predecessor, the Cadillac SRX. Within the first 100 words, it’s important to clarify the searcher’s intent: whether you’re comparing these two luxury SUVs for a new purchase, used vehicle evaluation, or understanding Cadillac’s design evolution, this article presents a detailed, fair, and forward-looking comparison. Though the SRX is no longer in production, its presence in the pre-owned market remains strong. Meanwhile, the XT4 represents Cadillac’s modern take on compact luxury. We explore both models through the lens of functionality, innovation, and brand evolution.
Design Philosophy: Then and Now
The Cadillac SRX, produced between 2004 and 2016, especially in its second generation (2010–2016), embodied a transitional phase for Cadillac—shifting from large, angular designs toward more compact luxury crossovers. In contrast, the XT4, introduced in 2019, signifies a fully modern expression of Cadillac’s design ethos: sharp, athletic, and youthful.
Exterior Styling Comparison:
- SRX: Tall stance, vertical lighting elements, bold grille, square proportions
- XT4: Sleek LED lights, sharper lines, lower profile, contemporary Cadillac grille
Interior Evolution:
- SRX: Analog instrumentation, real wood trim in higher trims, classic luxury
- XT4: Digital cluster, minimalist dashboard, customizable ambient lighting, more compact cabin design
Where the SRX leans into traditional American luxury, the XT4 pushes toward international competitiveness with cleaner aesthetics.

The XT4 is slightly smaller in every major dimension, giving it better city maneuverability and fuel efficiency.
Performance and Driving Dynamics
The SRX featured two main engines over its lifecycle, including a 3.6-liter V6 that delivered smooth, confident power. The XT4 opts for a turbocharged 2.0-liter 4-cylinder engine that emphasizes efficiency and low-end torque.

Fuel Economy (Approx.):
- SRX AWD: 16 mpg city / 23 mpg highway
- XT4 AWD: 22 mpg city / 29 mpg highway
While the SRX delivers a smoother highway feel due to its weight and V6 power, the XT4 feels lighter, quicker off the line, and more suited for urban driving.
Ride Comfort and Handling
SRX Ride Profile:
- Heavier and more grounded feel
- Softer suspension tuning

The XT4, thanks to modern chassis tuning and lighter architecture, handles corners better, while the SRX maintains a cruising luxury demeanor.
Technology and Infotainment
Cadillac has undergone a rapid transformation in its technology suite since the SRX era.

- Optional rear-seat entertainment
- Limited smartphone integration
XT4 Highlights:

While both vehicles offer safety features that were top-tier in their respective eras, the XT4 benefits from modern driver-assistance systems becoming more standard and refined.
Interior Space and Usability
Despite being smaller overall, the XT4 maintains respectable interior space due to better packaging.
Rear Legroom:
