Safety

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.

The E-Class Sedan’s driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The GS Series doesn’t offer a driver alert monitor.

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, available all wheel drive, lane departure warning systems, blind spot warning systems and rear cross-path warning.

For its top level performance in IIHS driver-side small overlap frontal, moderate overlap frontal, side impact, rear impact and roof-crush tests, its standard front crash prevention system, its “Good” rating in the new passenger-side small overlap crash test, and its headlight’s “Good” rating, the Insurance Institute for Highway Safety grants the E-Class Sedan its highest rating: “Top Pick Plus” for 2018, a rating granted to only 28 vehicles tested by the IIHS. The GS Series has not been fully tested, yet.

Warranty

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

Fuel Economy and Range

On the EPA test cycle the E 450 4MATIC Sedan 4MATIC gets better fuel mileage than the GS 350 AWD (20 city/28 hwy vs. 19 city/26 hwy).

Regardless of its engine, the E-Class Sedan’s engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. (Start/Stop isn’t accounted in present EPA fuel mileage tests.) Lexus doesn’t offers an automatic engine start/stop system on the GS Series.

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).

Transmission

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 GS Series.

Consumer Reports

Tires and Wheels

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).

The E-Class Sedan’s standard tires provide better handling because they have a lower 45 series profile (height to width ratio) that provides a stiffer sidewall than the GS 300’s standard 50 series tires.

For better ride, handling and brake cooling the E-Class Sedan has standard 18-inch wheels. Smaller 17-inch wheels are standard on the GS 300.

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.

Suspension and Handling

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 1.4 inches wider in the front and .5 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 1.8 seconds quicker than the GS 450h (25.1 seconds @ .77 average G’s vs. 26.9 seconds @ .68 average G’s).

Chassis

As tested by Car and Driver while at idle, the interior of the E 300 Sedan 4MATIC is quieter than the GS 350 (38 vs. 40 dB).

Passenger Space

The E-Class Sedan has .5 inches more front shoulder room, .4 inches more rear headroom and 1.4 inches more rear shoulder room than the GS Series.

Cargo Capacity

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.

Servicing Ease

The E-Class Sedan has a maintenance free battery for long life without checking the battery’s water level. The GS Series doesn’t have a maintenance free battery, so the water level in the battery’s cells must be checked often to prevent damage.

An ASSYST PLUS is standard on the E-Class Sedan to save the owner time and money by calculating maintenance intervals for oil changes, tire rotation and brake pad replacement based on odometer mileage. This takes the guesswork out of keeping your vehicle in top condition and helps it last longer. Lexus doesn’t offer a maintenance reminder on the GS Series.

Ergonomics

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 better shield the driver and front passenger’s vision, the E-Class Sedan has standard dual-element sun visors that can block glare from two directions simultaneously. The GS Series doesn’t offer secondary sun visors.

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, with the driver only controlling speed with the brake pedal. The GS Series doesn’t offer an automated parking system.

Model Availability

The Mercedes E-Class comes in coupe, convertible, sedan and station wagon bodystyles; the Lexus GS Series isn’t available as a coupe, convertible or station wagon.

Economic Advantages

Insurance will cost less for the E-Class Sedan owner. The Complete Car Cost Guide estimates that insurance for the E-Class Sedan will cost $560 less than the GS Series over a five-year period.

Recommendations

Consumer Reports® recommends both the Mercedes E-Class Sedan and the Lexus GS Series, based on reliability, safety and performance.

The E-Class was chosen as one of Car and Driver’s “Top Ten” in 2018. The GS Series has never been a Car and Driver “Top Ten” pick.

The Mercedes E-Class outsold the Lexus GS Series by over six to one during the 2018 model year.
