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 .6 inches wider in the front and 1.7 inches wider in the rear than the average track on the E-Class Sedan.

For better maneuverability, the G80’s turning circle is 2 feet tighter than the E-Class Sedan’s (36.2 feet vs. 38.2 feet). The G80’s turning circle is 1.6 feet tighter than the E 450 4MATIC Sedan’s (37.4 feet vs. 39 feet).

Passenger Space

Because it has more passenger and cargo room, the EPA rates the G80 a Large car, while the E-Class Sedan is rated a Mid-size.

The G80 has 9.7 cubic feet more passenger volume than the E-Class Sedan (107.7 vs. 98).

The G80 has 3.7 inches more front headroom, 4 inches more front legroom and .5 inches more front shoulder room than the E-Class Sedan.

Cargo Capacity

The G80 has a much larger trunk than the E-Class Sedan (15.3 vs. 13.1 cubic feet).

Ergonomics

In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The G80 3.8 AWD offers available headlight washers to keep headlight output high. The E-Class Sedan doesn’t offer headlight washers.

The G80 has standard heated front seats. Heated front seats cost extra on the E-Class Sedan. The G80 also offers optional heated rear seats to keep those passengers extremely comfortable in the winter. Heated rear seats aren’t available in the E-Class Sedan.

Economic Advantages

The G80 will cost the buyer less in the long run because of its superior resale value. The IntelliChoice estimates that the G80 will retain 40.26% to 44.12% of its original price after five years, while the E-Class Sedan only retains 38.57% to 39.14%.

IntelliChoice estimates that five-year ownership costs (depreciation, financing, insurance, fuel, fees, repairs and maintenance) for the Genesis G80 will be $12924 to $13699 less than for the Mercedes E-Class Sedan.

Recommendations

Consumer Reports® recommends the Genesis G80, based on reliability, safety and performance. The Mercedes E-Class Sedan isn't recommended.
