2026 Cadillac CT4 vs. Audi A4

Compact luxury sedans should make you feel something every time you get behind the wheel. The 2026 Cadillac CT4 does exactly that, blending bold innovation with the kind of driving engagement that turns an ordinary commute into something worth looking forward to. The team at Fields Cadillac St. Augustine knows this segment well, and when shoppers compare the CT4 to the 2025 Audi A4, a few key differences emerge.

More Power When You Want It

Both sedans start with turbocharged 2.0-liter four-cylinder engines, but the new Cadillac sedan takes things further. The standard engine produces 237 horsepower and 258 lb-ft of torque through a responsive 8-speed automatic. Where the A4 tops out at 261 horsepower in its highest-output configuration, the Cadillac CT4 lineup extends into the V-Series with a 2.7-liter Dual-Volute Turbo generating 325 horsepower and reaching 60 mph in just 4.8 seconds. For drivers who want a sedan that can genuinely thrill, Cadillac offers a performance ceiling the A4 simply doesn't reach.

A Cabin Built Around Innovation

The 2026 CT4 arrives with numerous premium comfort features on every trim, a thoughtful touch regardless of which model you choose. Premium Luxury and Sport trims raise the bar with standard ventilated front seats. Wireless Apple CarPlay® and Android Auto™ come standard, and the available Cadillac Super Cruise® delivers hands-free driving assistance across more than 200,000 miles of compatible highways. The A4 features a polished 10.1-inch MMI touchscreen and the available Virtual Cockpit digital display, but nothing in its lineup rivals the capability of Super Cruise®.

Confidence at Every Speed

Safety technology is standard and comprehensive in the CT4. Every model includes Automatic Emergency Braking, Forward Collision Alert, Front Pedestrian Braking, and an LED Reflective Windshield Collision Alert. Step up to the Premium Luxury and you'll add HD Surround Vision™ and an available Head-Up Display for even greater situational awareness. The A4 answers with its own suite of standard driver-assist features, but the Cadillac model's layered approach gives drivers more ways to stay aware and in control.
