Audi A6 vs BMW X3

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.

BMW offers the 2026 X3 in two flavors: 30 xDrive and M50. The latter is tuned for performance, but the base X3 30 xDrive is so good that you might be happy trading the M50’s outright speed and sheer capability for significant savings. BMW redesigned this compact luxury crossover in 2025, and the only tweaks for 2026 make the base model look and feel a little more upscale inside.

Verdict: For this review, we evaluated the BMW X3 M50. It was terrific, but with a sticker price more than $15,000 higher than the rewarding X3 30 xDrive, it’s hard to justify the extra money.
