Compare the2025 Mercedes E-Class SedanVS 2025 Genesis G80

The E-Class Sedan offers an optional Post Collision Brake, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The G80 doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.

Earlier warning of stopped traffic, traffic signals, dangerous road conditions, weather, or accidents, can keep driver's safer and prevent crashes. The E-Class Sedan has Car-to-X Communication, a system that seamlessly communicates important warnings to the driver about impending danger, if they're available. The G80 doesn’t offer a system that can receive automated systems from infrastructure or other vehicles.

Both the E-Class Sedan and the G80 have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, front seat center airbag, 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, blind spot warning systems, rearview cameras, rear cross-path warning, driver alert monitors, available all wheel drive and lane departure warning systems.

There are over 59 percent more Mercedes dealers than there are Genesis dealers, which makes it much easier should you ever need service under the E-Class Sedan’s warranty.

The E 450 Sedan’s standard 3.0 turbo 6-cylinder hybrid produces 75 more horsepower (375 vs. 300) and 58 lbs.-ft. more torque (369 vs. 311) than the G80 2.5T’s standard 2.5 turbo 4-cylinder.

On the EPA test cycle the E-Class Sedan gets better mileage than the G80:

Regenerative brakes improve the E-Class Sedan’s fuel efficiency by converting inertia back into energy instead of wasting it. The G80 doesn’t offer a regenerative braking system.

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Mercedes E-Class Sedan higher (6 to 7 out of 10) than the Genesis G80 (5). This means the E-Class Sedan produces up to 8 pounds less smog-producing pollutants than the G80 every 15,000 miles.

A nine-speed automatic is standard on the Mercedes E-Class Sedan, for better acceleration and lower engine speed on the highway. Only an eight-speed automatic is available for the G80.

For better stopping power the E 450 Sedan’s front brake rotors are larger than those on the G80:

The E-Class Sedan’s standard front and rear disc brakes are vented to help dissipate heat for shorter stops with less fading. The rear discs standard on the G80 2.5T are solid, not vented.

The E-Class Sedan stops much shorter than the G80:

The E-Class Sedan’s 245/35R21 front and 275/30R21 rear tires provide better handling because they have a lower 35 series front and 30 series rear profile (height to width ratio) that provides a stiffer sidewall than the G80 Sport Prestige’s 40 series front and 35 series rear tires.

For better ride, handling and brake cooling the E-Class Sedan has standard 21-inch wheels. The G80’s largest wheels are only 20-inches.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires available on the E-Class Sedan can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The G80 doesn’t offer run-flat tires.

The E-Class Sedan has a standard automatic front and rear load leveling suspension to keep ride height level with a heavy load or when towing. The E-Class Sedan’s height leveling suspension allows the driver to raise ride height for better off-road clearance and then lower it again for easier entering and exiting and better on-road handling. The G80 doesn’t offer a load leveling suspension.

The E-Class Sedan’s drift compensation steering can automatically compensate for road conditions which would cause the vehicle to drift from side to side, helping the driver to keep the vehicle straight more easily. The G80 doesn’t offer drift compensation steering.

The E 350 Sedan 4MATIC handles at .93 G’s, while the G80 pulls only .87 G’s of cornering force in a Car and Driver skidpad test.

The E 450 Sedan executes Motor Trend’s “Figure Eight” maneuver quicker than the G80 (25.8 seconds @ .73 average G’s vs. 26.2 seconds @ .68 average G’s).

To almost totally eliminate engine vibration in the passenger area, the E-Class Sedan Dynamic PLUS has an electronically controlled liquid-filled front engine mount. A computer-controlled electric current in the liquid changes its viscosity, allowing the mount to dampen the engine completely at all RPMs. The G80 uses conventional solid rubber engine mounts.

The E-Class Sedan’s standard rear seats fold to accommodate long and bulky cargo. The G80 doesn’t offer folding rear seats, only a ski pass-through.

Unlike the driver-only memory system in the G80, the E-Class Sedan has standard driver and passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat, steering wheel position and outside mirror angle and the front passenger seat also adjusts to the new passenger’s preset preferences.

The E-Class Sedan’s standard Keyless-Go allow you to unlock the doors from any outside door handle, open the trunk, and start the engine, all without removing the key from the pocket or purse. Proximity Key standard on the G80 doesn’t offer a sensor on the rear doors, so you’ll have to reach a front handle to unlock the rear door.

Heated windshield washer nozzles are optional on the E-Class Sedan to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The G80 doesn’t offer heated windshield washer nozzles.

To help drivers avoid possible obstacles, the E-Class Sedan offers optional cornering lights to illuminate around corners when the turn signals are activated. The G80 doesn’t offer cornering lights. The E-Class Sedan also offers optional adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Mercedes E-Class has a standard wireless phone charging system (Qi) in the center console. Only the G80 Sport Prestige/3.5T offers wireless charging.
