The E-Class Sedan’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The GS Series doesn’t offer pre-crash pretensioners.

The rear seatbelts optional on the E-Class Sedan 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 GS Series doesn’t offer inflatable seatbelts.

The E-Class Sedan offers an optional Surround View System to allow the driver to see objects all around the vehicle on a screen. The GS Series only offers a rear monitor and front and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the sides.

Both the E-Class Sedan and the GS Series have standard driver and passenger frontal airbags, front 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 lane departure warning systems and rear cross-path warning.

For its top level performance in IIHS driver and passenger-side small overlap frontal, moderate overlap frontal, side impact, roof strength and head restraint tests, its standard front crash prevention system, and its headlight’s “Good” rating, the Insurance Institute for Highway Safety grants the E-Class Sedan its highest rating: “Top Pick Plus” for 2019, a rating granted to only 55 vehicles tested by the IIHS. The GS Series has not been fully tested, yet.

Regenerative brakes improve the E-Class Sedan 53 AMG’s fuel efficiency by converting inertia back into energy instead of wasting it. The GS Series doesn’t offer a regenerative braking system.

In heavy traffic or at stoplights the E-Class Sedan’s engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. The engine is automatically restarted when the driver gets ready to move again. (Start/Stop isn’t accounted in present EPA fuel mileage tests.) The GS Series doesn’t offer an automatic engine start/stop system.

The E-Class Sedan 450/AMG 53’s standard fuel tank has 3.7 gallons more fuel capacity than the GS Series (21.1 vs. 17.4 gallons).

For better traction, the E-Class Sedan has larger standard tires than the GS Series (245/45R18 vs. 235/45R18). The E-Class Sedan’s optional tires are larger than the largest tires available on the GS Series (F:245/40R19 & R:275/35R19 vs. F:235/40R19 & R:265/35R19).

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 GS Series 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 GS Series 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 GS Series doesn’t offer drift compensation steering.

For a smoother ride and more stable handling, the E-Class Sedan’s wheelbase is 3.5 inches longer than on the GS Series (115.7 inches vs. 112.2 inches).

For better handling and stability, the average track (width between the wheels) on the E-Class Sedan is 1.3 inches wider in the front and .4 inches wider in the rear than the track on the GS Series.

The E-Class Sedan 4MATIC handles at .92 G’s, while the GS 350 pulls only .88 G’s of cornering force in a Car and Driver skidpad test.

The E-Class Sedan 4MATIC executes Motor Trend’s “Figure Eight” maneuver 1 seconds quicker than the GS 350 (25.1 seconds @ .77 average G’s vs. 26.1 seconds @ .72 average G’s).

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

To make loading groceries and cargo easier when your hands are full, the E-Class Sedan’s trunk can be opened and closed just by kicking your foot under the back bumper, leaving your hands completely free. The GS Series doesn’t offer a hands-free gesture to open its trunk, forcing you to put cargo down if your hands are full.

The E-Class Sedan’s power window, power lock, power mirror and cruise control switches are lit from behind, making them plainly visible and easier to operate at night. The GS Series’ cruise control switches are unlit, making them difficult to find at night and operate safely.

The E-Class Sedan’s rain-sensitive wipers adjust their speed and turn on and off automatically based on the amount of rainfall on the windshield. This allows the driver to concentrate on driving without constantly adjusting the wipers. The GS Series’ standard manually variable intermittent wipers have to be constantly adjusted.

Heated windshield washer fluid is standard on the E-Class Sedan to defrost the washer nozzles and quickly clear ice and frost from the windshield without scraping. The GS Series doesn’t offer heated windshield washer fluid.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Mercedes E-Class offers an optional wireless phone charging system (Qi) in the center console. The GS Series doesn’t offer wireless personal charging.

The E-Class Sedan offers an optional 115-volt a/c outlet on the center console, allowing you to recharge a laptop or run small household appliances without special adapters that can break or get misplaced. The GS Series doesn’t offer a house-current electrical outlet.

The E-Class Sedan’s optional Active Parking Assist can parallel park or back into a parking spot by itself, starting, stopping and changing direction automatically. The GS Series doesn’t offer an automated parking system.
