Audi A6 vs BMW 5 Series

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.

The BMW 5 Series is one of three cars that prove the country known for Autobahns, the Nürburgring, and Oktoberfest builds the best luxury sedans on the planet. It competes with the Audi A6 and Mercedes-Benz E-Class, each taking a distinct approach to design but measuring up closely in other parameters. The 2026 5 Series is virtually unchanged, entering its third year following a 2024 redesign.

Verdict: Putting BMW’s love-it-or-hate-it design aside, the 2026 5 Series is a sensational automobile offering the right blend of luxury, technology, and performance. Choose the M Sport setup for maximum driving enjoyment, or stick with the standard specification to emphasize luxury. Either way, the styling is the most controversial thing about the 5 Series.
