The 5 Series Sedan’s optional 275/30R20 rear tires provide better handling because they have a lower 30 series profile (height to width ratio) that provides a stiffer sidewall than the A6 Prestige’s optional 35 series tires.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires standard on the 5 Series Sedan can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The A6 doesn’t offer run-flat tires.

The 5 Series Sedan 540i/M550i offers active sway bars, which help keep it flat and controlled during cornering, but disconnect at lower speeds to smooth the ride and offer greater off-road suspension articulation.

The M550i offers an available adjustable active suspension system, which counteracts cornering forces actively, limiting body roll and improving handling and stability. Audi doesn’t offer an active suspension on the A6.
