For better traction, the G80 has larger standard tires than the E-Class Sedan (245/50R18 vs. 225/55R18).

The G80 2.5T Standard’s standard tires provide better handling because they have a lower 50 series profile (height to width ratio) that provides a stiffer sidewall than the E-Class Sedan’s standard 55 series tires.

The G80 has a standard space-saver spare tire so you can replace a flat tire and drive to have the flat repaired or replaced. A spare tire isn’t available on the E-Class Sedan; it requires you to depend on its run-flat tires, which limits mileage and speed before they are repaired. If a run-flat is damaged beyond repair by a road hazard your vehicle will have to be towed. Some tire options on the E-Class Sedan don’t have a run-flat feature, either.

For a smoother ride and more stable handling, the G80’s wheelbase is 1.9 inches longer than on the E-Class Sedan (118.5 inches vs. 116.6 inches).

The front grille of the G80 uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The E-Class Sedan doesn’t offer active grille shutters.

The G80 has a standard heated steering wheel to take the chill out of steering on extremely cold winter days before the car heater warms up. A heated steering wheel costs extra on the E-Class Sedan.
