Both the RS 7 and AMG E-Class Sedan have child safety locks to prevent children from opening the rear doors. The RS 7 has power child safety locks, allowing the driver to activate and deactivate them from the driver's seat and to know when they're engaged. The AMG E-Class Sedan’s child locks have to be individually engaged at each rear door with a manual switch. The driver can’t know the status of the locks without opening the doors and checking them.

The Audi RS 7 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 AMG E-Class Sedan doesn’t offer a front passenger side knee airbag.

The RS 7 has a standard Secondary Collision Brake Assist, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The AMG E-Class Sedan 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.

A passive infrared night vision system optional on the RS 7 helps the driver to more easily detect people, animals or other objects in front of the vehicle at night. Using an infrared camera to detect heat, the system then displays the image on a monitor in the dashboard. The AMG E-Class Sedan doesn’t offer a night vision system.

The RS 7’s standard lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane. A lane departure warning system costs extra on the AMG E-Class Sedan.

Both the RS 7 and the AMG E-Class Sedan 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, all wheel drive, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, around view monitors, available blind spot warning systems and rear cross-path warning.

The Audi RS 7 weighs 441 pounds more than the Mercedes AMG E-Class Sedan. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts.

The National Highway Traffic Safety Administration does side impact tests on new vehicles. In this test, which crashes the vehicle into a flat barrier at 38.5 MPH and into a post at 20 MPH, results indicate that the Audi RS 7 is safer than the Mercedes AMG E-Class Sedan:

	RS 7	AMG E-Class Sedan
	Front Seat
STARS	5 Stars	5 Stars
Chest Movement	.9 inches	1.1 inches
	Rear Seat
STARS	5 Stars	5 Stars
HIC	135	215
Spine Acceleration	43 G’s	46 G’s
	Into Pole
STARS	5 Stars	5 Stars
Spine Acceleration	39 G’s	43 G’s
Hip Force	514 lbs.	836 lbs.

New test not comparable to pre-2011 test results. More stars = Better. Lower test results = Better.

Warranty

The RS 7’s corrosion warranty is 7 years longer than the AMG E-Class Sedan’s (12 vs. 5 years).

Reliability

From surveys of all its subscribers, Consumer Reports’ January 2021 Auto Issue reports that Audi vehicles are more reliable than Mercedes vehicles. Consumer Reports ranks Audi 6 places higher in reliability than Mercedes.

Engine

The RS 7’s 4.0 turbo V8 hybrid produces 162 more horsepower (591 vs. 429) and 206 lbs.-ft. more torque (590 vs. 384) than the AMG E 53’s standard 3.0 turbo 6-cylinder hybrid.

Brakes and Stopping

For better stopping power the RS 7’s brake rotors are larger than those on the AMG E-Class Sedan:

	RS 7	RS 7 CCB	AMG E 53	AMG E 63 S
Front Rotors	16.5 inches	17.3 inches	14.6 inches	15.8 inches
Rear Rotors	14.6 inches	14.6 inches	14.2 inches	14.2 inches

The RS 7 stops shorter than the AMG E-Class Sedan:

	RS 7	AMG E-Class Sedan
70 to 0 MPH	151 feet	155 feet	Car and Driver

Tires and Wheels

For better traction, the RS 7 has larger standard tires than the AMG E-Class Sedan (275/35R21 vs. 245/40R19). The RS 7’s optional tires are larger than the largest tires available on the AMG E-Class Sedan (285/30R22 vs. 265/35R20).

The RS 7’s standard tires provide better handling because they have a lower 35 series profile (height to width ratio) that provides a stiffer sidewall than the AMG E 53’s standard 40 series front tires. The RS 7’s optional tires have a lower 30 series profile than the AMG E 63 S’ 35 series front tires.

For better ride, handling and brake cooling the RS 7 has standard 21-inch wheels. Smaller 19-inch wheels are standard on the AMG E 53. The RS 7’s optional 22-inch wheels are larger than the 20-inch wheels on the AMG E 63 S.

Suspension and Handling

For better handling and stability, the track (width between the wheels) on the RS 7 is 1.2 inches wider in the front and 2.1 inches wider in the rear than the average track on the AMG E-Class Sedan.

For better maneuverability, the RS 7’s turning circle is 1 foot tighter than the AMG E-Class Sedan’s (40 feet vs. 41 feet).

Chassis

As tested by Car and Driver, the interior of the RS 7 is quieter than the AMG E 63 S:

	RS 7	AMG E-Class Sedan
Full-Throttle	79 dB	84 dB

Passenger Space

For enhanced passenger comfort on long trips the RS 7’s rear seats recline. The AMG E-Class Sedan’s rear seats don’t recline.

Ergonomics

In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The RS 7 has standard headlight washers to keep headlight output high. The AMG E-Class Sedan doesn’t offer headlight washers.

To shield the driver and front passenger’s vision over a larger portion of the windshield and side windows, the RS 7 has standard extendable sun visors. The AMG E-Class Sedan doesn’t offer extendable visors.

The RS 7 has a standard heated steering wheel to take the chill out of steering on extremely cold winter days before the car heater warms up. A heated steering wheel costs extra on the AMG E-Class Sedan.
