For enhanced safety, the front and rear seat shoulder belts of the Mercedes E-Class Sedan 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 Acura TLX doesn’t offer pretensioners for the rear seat belts.

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 TLX doesn’t offer inflatable seatbelts.

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 TLX doesn’t offer a driver alert monitor.

Both the E-Class Sedan and the TLX 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, rearview cameras, available lane departure warning systems, around view monitors and rear cross-path warning.

A significantly tougher test than their original offset frontal crash test, the Insurance Institute for Highway Safety does 40 MPH small overlap frontal offset crash tests. In this test, where only 25% of the total width of the vehicle is struck, results indicate that the Mercedes E-Class Sedan is safer than the TLX:

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 TLX was not even a standard “Top Pick” for 2016.

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

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.) Acura only offers an automatic engine start/stop system on the TLX SH-AWD.

The E-Class Sedan 450/AMG 53’s standard fuel tank has 3.9 gallons more fuel capacity than the TLX (21.1 vs. 17.2 gallons).

For better traction, the E-Class Sedan has larger standard tires than the TLX (245/45R18 vs. 225/55R17).

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 TLX’s standard 55 series tires. The E-Class Sedan’s optional 275/35R19 rear tires have a lower 35 series profile than the TLX A-Spec’s 40 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 TLX.

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 TLX doesn’t offer run-flat tires.

The E-Class Sedan offers an optional driver-adjustable suspension system. It allows the driver to choose between an extra-supple ride, reducing fatigue on long trips, or a sport setting, which allows maximum control for tricky roads. The TLX’s suspension doesn’t offer adjustable shock absorbers.

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 TLX 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 TLX doesn’t offer drift compensation steering.

For a smoother ride and more stable handling, the E-Class Sedan’s wheelbase is 6.4 inches longer than on the TLX (115.7 inches vs. 109.3 inches).

The E-Class Sedan’s front to rear weight distribution is more even (54.2% to 45.8%) than the TLX’s (59.7% to 40.3%). This gives the E-Class Sedan more stable handling and braking.

The E-Class Sedan 4MATIC handles at .93 G’s, while the TLX V6 SH-AWD pulls only .82 G’s of cornering force in a Motor Trend skidpad test.

The E-Class Sedan 4MATIC executes Motor Trend’s “Figure Eight” maneuver 1.9 seconds quicker than the TLX (25.1 seconds @ .77 average G’s vs. 27 seconds @ .74 average G’s).

For better maneuverability, the E-Class Sedan’s turning circle is .7 feet tighter than the TLX V6’s (38.1 feet vs. 38.8 feet). The E 450 4MATIC Sedan’s turning circle is .5 feet tighter than the TLX SH-AWD’s (39 feet vs. 39.5 feet).

Because it has more passenger and cargo room, the EPA rates the E-Class Sedan a Mid-size car, while the TLX is rated a Compact.

The E-Class Sedan has 4.7 cubic feet more passenger volume than the TLX (98 vs. 93.3).

The E-Class Sedan has .1 inches more front headroom, .3 inches more front shoulder room, 1.5 inches more rear headroom, 1.7 inches more rear legroom and 1.7 inches more rear shoulder room than the TLX.

The engine in the E-Class Sedan is mounted longitudinally (North-South), instead of sideways, as in the TLX. This makes it easier to service and maintain, because there are no rear spark plugs and the accessory belts are in front.

J.D. Power and Associates surveys of service recipients show that Mercedes service is better than Acura. J.D. Power ranks Mercedes fifth in service department satisfaction. With a 4% lower rating, Acura is ranked 6th.

Unlike the driver-only memory system in the TLX, 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 offers an optional heads-up display that projects speed and navigation instruction readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The TLX doesn’t offer a heads-up display.

The power windows standard on both the E-Class Sedan and the TLX have locks to prevent small children from operating them. When the lock on the E-Class Sedan is engaged the driver can still operate all of the windows, for instance to close one opened by a child. The TLX prevents the driver from operating the other windows just as it does the other passengers.

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 TLX’s standard intermittent wipers change speed with vehicle speed, but can’t turn on and off or change speed based on changing rainfall.

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 TLX doesn’t offer heated windshield washer fluid.

The Insurance Institute for Highway Safety (IIHS) conducts detailed tests on headlights for their range both straight ahead and in curves and to be certain they don’t exceed acceptable amounts of glare to oncoming drivers. The E-Class Sedan’s headlights were rated “Good” to “Acceptable” by the IIHS, while the TLX’s headlights are rated “Acceptable.”

To help drivers avoid possible obstacles, the E-Class Sedan has standard cornering lights to illuminate around corners when the turn signals are activated. The TLX 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.

A power rear sunshade is optional in the E-Class Sedan to help block heat and glare for the rear passengers. The TLX doesn’t offer a rear sunshade.

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 TLX 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 TLX doesn’t offer an automated parking system.
