Safety

For enhanced safety, the front and rear seat shoulder belts of the Genesis G80 are height-adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The Mercedes E-Class Sedan has only front height-adjustable seat belts.

The G80 has standard Anti-Whiplash Front Head Restraints, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the Anti-Whiplash Front Head Restraints system moves the headrests forward to prevent neck and spine injuries. The E-Class Sedan doesn’t offer a whiplash protection system.

Both the G80 and the E-Class Sedan have standard driver and passenger frontal airbags, front and rear side-impact airbags, driver knee airbags, side-impact head airbags, front and rear seatbelt pretensioners, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, rearview cameras, driver alert monitors, available all wheel drive and rear parking sensors.

Consumer Reports

Tires and Wheels

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 models of the E-Class Sedan don’t even offer run-flats.

Suspension and Handling

For a smoother ride and more stable handling, the G80’s wheelbase is 2.8 inches longer than on the E-Class Sedan (118.5 inches vs. 115.7 inches).

For better handling and stability, the average track (width between the wheels) on the G80 is 0 inches wider in the front and 1.3 inches wider in the rear than the average track on the E-Class Sedan.

For better maneuverability, the G80’s turning circle is 1.9 feet tighter than the E-Class Sedan’s (36.2 feet vs. 38.1 feet). The G80’s turning circle is .7 feet tighter than the E-Class Sedan’s (37.4 feet vs. 38.1 feet).
