Cushy Comfort: It's a Tie!
The A4's generous interior space makes it feel more like a midsize sedan than a compact one!
That's especially true in the back row; if you're shopping for extra rear-seat head- and legroom, you're going to love it. Plus, this Audi sedan delivers a solid luxury experience, with a hushed ride, spiffy interior design, and high-end cabin materials.
Compared to its Audi competitor, the Cadillac CT4 actually delivers an extra inch of front-seat head- and legroom! While the A4 offers slightly more backseat space, the CT4 still provides plush support for your loved ones.

Modern Tech: 2026 Cadillac CT4
When it comes to hands-free cruising, Cadillac has Audi on the run. The A4 doesn't offer anything like the CT4's Super Cruise package, making the CT4 the only option for semi-autonomous highway driving!
Of course, both compact luxury sedans treat you to a host of high-end tech features. For example, both come standard with touchscreen infotainment and a variety of driver safety aids. And as you move up each model's trim hierarchy, you'll discover upgrades like premium audio and a heads-up display.
High-End Performance: 2026 Cadillac CT4
Compared to the CT4's base engine, it's true that the Audi A4 comes standard with a little extra horsepower. However, only the CT4 is available with a high-octane performance upgrade! Generating 325 horses, this Cadillac sedan leaves its 261-horsepower Audi counterpart in the proverbial dust. And with available all-wheel drive, the CT4 also gives the A4 a run for its money in the handling department.
