Safety

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 LS Series doesn’t offer inflatable seatbelts.

Both the E-Class Sedan and the LS 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 all wheel drive, lane departure warning systems, blind spot warning systems, around view monitors 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 LS Series has not been 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.

Reliability

A reliable vehicle saves its owner time, money and trouble. Nobody wants to be stranded or have to be without a vehicle while it’s being repaired. Consumer Reports rates the E-Class Sedan’s reliability 30 points higher than the LS Series.

Engine

The AMG E 53 Sedan’s 3.0 turbo 6 cyl. hybrid produces 13 more horsepower (429 vs. 416) than the LS 500’s optional 3.4 turbo V6.

Fuel Economy and Range

On the EPA test cycle the E 450 4MATIC Sedan 4MATIC gets better fuel mileage than the LS 500 AWD (20 city/28 hwy vs. 18 city/27 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 only offers an automatic engine start/stop system on the LS Series Hybrid.

Brakes and Stopping

The E-Class Sedan stops much shorter than the LS Series:

Consumer Reports

Tires and Wheels

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 LS Series’ standard 50 series tires. The E-Class Sedan’s optional 245/40R19 front and 275/35R19 rear tires have a lower 40 series front and 35 series rear profile than the LS Series F Sport’s 45 series front and 40 series rear tires.

Suspension and Handling

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 LS Series doesn’t offer drift compensation steering.

The E-Class Sedan 4MATIC handles at .93 G’s, while the LS 500 AWD pulls only .85 G’s of cornering force in a Motor Trend skidpad test.

The E-Class Sedan 4MATIC executes Motor Trend’s “Figure Eight” maneuver quicker than the LS 500 AWD (25.1 seconds @ .77 average G’s vs. 25.7 seconds @ .73 average G’s).

Chassis

The Mercedes E-Class Sedan may be more efficient, handle and accelerate better because it weighs about 900 to 950 pounds less than the Lexus LS Series.

The E-Class Sedan is 1 foot shorter than the LS Series, making the E-Class Sedan easier to handle, maneuver and park in tight spaces.

Passenger Space

The E-Class Sedan has .1 inches more front headroom, .7 inches more front legroom, .9 inches more rear headroom and .7 inches more rear shoulder room than the LS Series.

Cargo Capacity

The E-Class Sedan’s standard rear seats fold to accommodate long and bulky cargo. The LS Series doesn’t offer folding rear seats.

Ergonomics

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 LS 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 LS Series doesn’t offer secondary sun visors.

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 LS 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 LS Series isn’t available as a coupe, convertible or station wagon.

Recommendations

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

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

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