2026 Audi A6 vs 2025 Cadillac CT5

A relative bargain in the premium midsize car segment, the 2025 CT5 sedan receives several changes to keep it appealing. Mostly, they pertain to technology, and the new 33-inch display containing digital instrumentation and a new infotainment system is the most obvious manifestation of that. In addition, the CT5 gets more standard and available safety features and driver assistance tech, updated audio, new front-end styling, and a couple of new paint colours.

Verdict: Despite the updates for 2025, the Cadillac CT5 is starting to look and feel like an older car. Also, compared to its rivals, it lacks polish and refinement. However, it is a bargain when cross-shopping it with the Audi A6, BMW 5 Series, and Mercedes-Benz E-Class. Its tech is impressive, too.

The redesigned 2026 Audi A6 marks the ninth generation of midsize luxury sedans from Ingolstadt, Germany. While it shares a name and some tech features with the Audi A6 e-tron introduced for the 2025 model year, the gasoline A6 is an otherwise different vehicle based on the same Premium Platform Combustion (PPC) as the A5 sedan and Q5 crossover. A redesign was certainly needed as most other midsize luxury sedans—specifically the BMW 5 Series and the Mercedes-Benz E-Class—were renewed more recently, and we haven’t had a genuinely new A6 since the 2020 model year.

Verdict: On paper, the A6 looks like more of a premium product than before, but it doesn’t feel that way from behind the wheel, and the tech is a work in progress.
