The 8 Series Gran Coupe M550i/Alpina B8 has 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. This helps keep the tires glued to the road on-road and off. The S7 doesn’t offer an active sway bar system.

The 8 Series Gran Coupe M550i/Alpina B8 offers an available 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 S7.
