- Compared to the Audi A4 (from $43,395*), the Cadillac CT4 (from $36,000*) comes at the most reasonable price.
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. Plus, Cadillac's luxury sedan is available with just about every imaginable creature comfort, from leather upholstery to heated and ventilated front seats!
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.
