For enhanced safety, the front and rear seat shoulder belts of the Mercedes EQS have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The Kia EV6 doesn’t offer pretensioners for its rear seat belts.

The EQS’ pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The EV6 doesn’t offer pre-crash pretensioners.

The Mercedes EQS has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags helps prevent the driver and front passenger from sliding under their seatbelts or the main frontal airbags; this keeps them better positioned during a collision for maximum protection. Knee airbags also help keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The EV6 doesn’t offer a front passenger side knee airbag.

The rear seatbelts optional on the EQS inflate when a collision is detected, helping to spread crash forces over a much larger area of the body and limiting head and neck movement. This can help prevent spinal and internal injuries. The EV6 doesn’t offer inflatable seatbelts.

The EQS’ standard pretensioning seatbelts also sense rear collisions and remove slack from the seatbelts to help protect the occupants from whiplash and other injuries. The EV6 doesn’t offer a whiplash protection system.

The EQS has a standard Post Collision Brake, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The EV6 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 EQS has Car-to-X Communication, a system that seamlessly communicates important warnings to the driver about impending danger, if they're available. The EV6 doesn’t offer a system that can receive automated systems from infrastructure or other vehicles.

Both the EQS and the EV6 have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning and driver alert monitors.

The Mercedes EQS weighs 705 to 1880 pounds more than the Kia EV6. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts.

Warranty

The EQS’ 5 year corrosion warranty has no mileage limitations, but the corrosion warranty on the EV6 runs out after 100,000 miles.

Transmission

The EQS AMG’s launch control uses engine electronics to hold engine RPM’s precisely in order to provide the most stable and rapid acceleration possible, using all of the available traction. The EV6 doesn’t offer launch control.

Brakes and Stopping

For better stopping power the EQS’ brake rotors are larger than those on the EV6:

	EQS	AMG EQS CCB	EV6	EV6 GT
Front Rotors	15.3 inches	17.4 inches	12.8 inches	15 inches
Rear Rotors	14.9 inches	14.9 inches	12.8 inches	14.2 inches

The EQS’ standard front and rear disc brakes are vented to help dissipate heat for shorter stops with less fading. The rear discs standard on the EV6 are solid, not vented.

The EQS AMG offers optional heat-treated ceramic brake rotors, which last ten to twenty times as long as conventional cast iron rotors, don’t rust, don’t fade during repeated high speed braking, and their lighter weight contribute to better braking, handling and acceleration. The EV6 doesn’t offer ceramic brake rotors.

The EQS stops much shorter than the EV6:

	EQS	EV6
100 to 0 MPH	333 feet	335 feet	Car and Driver
70 to 0 MPH	167 feet	181 feet	Car and Driver

Tires and Wheels

For better traction, the EQS has larger standard tires than the EV6 (255/45R20 vs. 235/55R19). The AMG EQS’ tires are larger than the largest tires available on the EV6 (275/40R21 vs. 255/45R20).

The EQS’ standard tires provide better handling because they have a lower 45 series profile (height to width ratio) that provides a stiffer sidewall than the EV6’s standard 55 series tires. The EQS’ optional tires have a lower 35 series profile than the EV6 GT’s 40 series tires.

For better ride, handling and brake cooling the EQS has standard 20-inch wheels. Smaller 19-inch wheels are standard on the EV6. The EQS’ optional 22-inch wheels are larger than the 21-inch wheels on the EV6 GT.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires available on the EQS can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The EV6 doesn’t offer run-flat tires.

Suspension and Handling

The front and rear suspension of the EQS uses air springs for a smoother, controlled ride than the EV6, which uses coil springs. Air springs maintain proper ride height and ride more smoothly.

The EQS has a standard automatic front and rear load leveling suspension to keep ride height level with a heavy load or when towing. The EQS’ 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 EV6 doesn’t offer a load leveling suspension.

The EQS’ 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 EV6 doesn’t offer drift compensation steering.

For a smoother ride and more stable handling, the EQS’ wheelbase is 12.2 inches longer than on the EV6 (126.4 inches vs. 114.2 inches).

For better handling and stability, the average track (width between the wheels) on the EQS is 1.6 inches wider in the front and 1.7 inches wider in the rear than the average track on the EV6.

The EQS’ front to rear weight distribution is more even (50% to 50%) than the EV6’s (48.3% to 51.7%). This gives the EQS more stable handling and braking.

The AMG EQS 4MATIC handles at .92 G’s, while the EV6 Wind e-AWD pulls only .85 G’s of cornering force in a Car and Driver skidpad test.

For better maneuverability, the EQS w/10° rear-wheel steering’s turning circle is 2.4 feet tighter than the EV6’s (35.8 feet vs. 38.2 feet). The AMG EQS’ turning circle is 1.5 feet tighter than the EV6 GT’s (37.7 feet vs. 39.2 feet).

Chassis

The EQS uses computer-generated active noise cancellation to help remove annoying noise and vibration from the passenger compartment, especially at low frequencies. The EV6 doesn’t offer active noise cancellation.

Passenger Space

The EQS has 1.4 inches more front headroom, 1.7 inches more front shoulder room, 1.4 inches more rear legroom and 3.5 inches more rear shoulder room than the EV6.

Cargo Capacity

The EQS has a larger cargo volume with its rear seat folded than the EV6 with its rear seat folded (63 vs. 50.2 cubic feet).

A standard locking glovebox keeps your small valuables safer in the EQS. The EV6 doesn’t offer locking storage for small valuables.

Ergonomics

Unlike the driver-only memory seat and mirrors in the EV6 Light/Wind/GT-Line, the EQS 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 EQS’ front and rear power windows all open or close fully with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside the car. The EV6’s rear power window switches have to be held the entire time to open or close them fully.

If the windows are left open on the EQS the driver can close them all from a distance using the remote. On a hot day the driver can also lower the windows the same way. The driver of the EV6 can only close the windows from inside the vehicle, with the ignition on.

The EQS’ standard Keyless-Go allow you to unlock the doors from any outside door handle, open the trunk, and start the car, all without removing the key from the pocket or purse. Smart Key standard on the EV6 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 fluid is optional on the EQS to defrost the washer nozzles and quickly clear ice and frost from the windshield without scraping. The EV6 doesn’t offer heated windshield washer fluid.

Consumer Reports rated the EQS’ headlight performance “Very Good,” a higher rating than the EV6’s headlights, which were rated “Good.”

To help drivers avoid possible obstacles, the EQS has standard cornering lights to illuminate around corners when the turn signals are activated. The EV6 doesn’t offer cornering lights. The EQS also has standard adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle.

The EQS’ standard rear and side view mirrors have an automatic dimming feature. These mirrors can be set to automatically darken quickly when headlights shine on them, keeping following vehicles from blinding or distracting the driver. The EV6 has an automatic rear view mirror, but its side mirrors don’t dim.

The EQS has standard front air conditioned seats and offers them optionally in the rear. This keeps the passengers comfortable and takes the sting out of hot seats in summer. The EV6 doesn’t offer air-conditioned seats in the rear.

The EQS offers optional massaging front and rear seats in order to maximize comfort and eliminate fatigue on long trips. Massaging seats aren’t available in the EV6.

Both the Mercedes EQS and the Kia EV6 have a standard Qi wireless phone charging system in the front seat. To easily keep personal devices charged in the rear seat, without cables tangling and wearing out, the EQS also has a standard wireless charging system.
