The 7 Series’ standard 255/45R20 front and 285/40R20 rear tires provide better handling because they have a lower 45 series front and 40 series rear profile (height to width ratio) that provides a stiffer sidewall than the E-Class Sedan’s standard 55 series tires.

The 7 Series 760i/750e 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. This helps keep the tires glued to the road on-road and off. The E-Class Sedan doesn’t offer an active sway bar system.

The front and rear suspension of the 7 Series uses air springs for a smoother, controlled ride than the E-Class Sedan, which uses coil springs. Air springs maintain proper ride height and ride more smoothly.
