Tires and Wheels

For better traction and acceleration, the G90 has larger rear tires than the E-Class Sedan (275/40R19 vs. 245/45R18).

The G90’s 275/40R19 rear tires provide better handling because they have a lower 40 series profile (height to width ratio) that provides a stiffer sidewall than the E-Class Sedan’s standard 45 series tires.

For better ride, handling and brake cooling the G90 has standard 19-inch wheels. Smaller 18-inch wheels are standard on the E-Class Sedan.

The G90 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 G90’s wheelbase is 8.7 inches longer than on the E-Class Sedan (124.4 inches vs. 115.7 inches).

For better handling and stability, the track (width between the wheels) on the G90 is 1.2 inches wider in the front and 1.4 inches wider in the rear than the average track on the E-Class Sedan.

The G90’s front to rear weight distribution is more even (51% to 49%) than the E-Class Sedan’s (54.2% to 45.8%). This gives the G90 more stable handling and braking.

Passenger Space

Because it has more passenger and cargo room, the EPA rates the G90 a Large car, while the E-Class Sedan is rated a Mid-size.

The G90 has 15.2 cubic feet more passenger volume than the E-Class Sedan (113.2 vs. 98).

The G90 has 3.7 inches more front headroom, 4.6 inches more front legroom, 1.3 inches more front shoulder room, 1.6 inches more rear legroom and .8 inches more rear shoulder room than the E-Class Sedan.

For enhanced passenger comfort on long trips the G90 5.0’s rear seats recline. The E-Class Sedan’s rear seats don’t recline.

Cargo Capacity

The G90 has a much larger trunk than the E-Class Sedan (15.7 vs. 13.1 cubic feet).


The G90 has standard heated front seats. Heated front seats cost extra on the E-Class Sedan. The G90 also has standard heated rear seats to keep those passengers extremely comfortable in the winter. Heated rear seats aren’t available in the E-Class Sedan.

The G90 has standard front air conditioned seats and the G90 5.0 also has them in the rear. This keeps the passengers comfortable and takes the sting out of hot seats in summer. The E-Class Sedan doesn’t offer air-conditioned seats in the rear.

The G90 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.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Genesis G90 has a standard wireless phone charging system (Qi) for the front seat. Wireless charging costs extra on the E-Class Sedan.
