The middle row seatbelts optional on the AMG E 63 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 S7 doesn’t offer inflatable seatbelts.

The AMG E 63 has a standard Surround View System to allow the driver to see objects all around the vehicle on a screen. The S7 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.

To help make backing safer, the AMG E 63’s cross-path warning system uses wide-angle radar in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. The S7 doesn’t offer a cross-path warning system.

The AMG E 63’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 S7 doesn’t offer a driver alert monitor.

Both the AMG E 63 and the S7 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, daytime running lights, blind spot warning systems, rearview cameras and available lane departure warning systems.


There are over 26 percent more Mercedes dealers than there are Audi dealers, which makes it easier should you ever need service under the AMG E 63’s warranty.


To reliably start during all conditions and help handle large electrical loads, the AMG E 63 has a standard 850-amp battery. The S7’s 520-amp battery isn’t as powerful.

J.D. Power and Associates’ 2018 Initial Quality Study of new car owners surveyed provide the statistics that show that Mercedes vehicles are better in initial quality than Audi vehicles. J.D. Power ranks Mercedes 15th in initial quality, above the industry average. With 13 more problems per 100 vehicles, Audi is ranked 25th, below the industry average.


The AMG E 63’s 4.0 turbo V8 produces 153 more horsepower (603 vs. 450) and 221 lbs.-ft. more torque (627 vs. 406) than the S7’s 4.0 turbo V8.

Environmental Friendliness

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Mercedes AMG E 63 higher (5 out of 10) than the Audi S7 (3). This means the AMG E 63 produces up to 16.5 pounds less smog-producing pollutants than the S7 every 15,000 miles.


A nine-speed automatic is standard on the Mercedes AMG E 63, for better acceleration and lower engine speed on the highway. Only a seven-speed automatic is available for the S7.

The AMG E 63 offers optional heat-treated ceramic brake rotors, which last ten to twenty times as long as conventional cast iron rotors, don’t rust, don’t fade during repeated high speed braking, and their lighter weight contribute to better braking, handling and acceleration. The S7 doesn’t offer ceramic brake rotors.

Car and Driver

Tires and Wheels

For better traction and acceleration, the AMG E 63 has larger rear tires than the S7 (295/30R20 vs. 265/35R20). The AMG E 63’s rear tires are larger than the largest rear tires available on the S7 (295/30R20 vs. 275/30R21).

The AMG E 63’s 295/30R20 rear tires provide better handling because they have a lower 30 series profile (height to width ratio) that provides a stiffer sidewall than the S7’s standard 35 series tires.

Suspension and Handling

The AMG E 63’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 S7 doesn’t offer drift compensation steering.

The AMG E 63 S Sedan handles at 1.01 G’s, while the S7 pulls only .97 G’s of cornering force in a Car and Driver skidpad test.


As tested by Car and Driver while cruising at 70 MPH, the interior of the AMG E 63 S Sedan is quieter than the S7 (66 vs. 70 dB).

Passenger Space

The AMG E 63 Wagon has standard seating for 7 passengers; the S7 can only carry 4. The AMG E 63 Sedan has standard seating for 5.

The AMG E 63 has 4 cubic feet more passenger volume than the S7 (98 vs. 94).

The AMG E 63 Sedan has .5 inches more front headroom, .1 inches more front legroom, .6 inches more front shoulder room, 1.6 inches more rear headroom and 1.2 inches more rear shoulder room than the S7.

Cargo Capacity

With its sedan body style, valet key, locking rear seatbacks and remote trunk release in the glovebox, the AMG E 63 offers cargo security. The S7’s non-lockable folding seat defeats cargo security.

Servicing Ease

J.D. Power and Associates surveys of service recipients show that Mercedes service is better than Audi. J.D. Power ranks Mercedes fifth in service department satisfaction. With a 13% lower rating, Audi is ranked 8th.


The AMG E 63 has a standard remote vehicle starting system, so the vehicle can be started from inside the driver's house. This allows the driver to comfortably warm up the engine before going out to the vehicle. The climate system will also automatically heat or cool the interior. The S7 doesn’t offer a remote starting system.

A power rear sunshade is optional in the AMG E 63 Sedan to help block heat and glare for the rear passengers. The S7 doesn’t offer a rear sunshade.

The AMG E 63 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 S7 doesn’t offer a house-current electrical outlet.

The AMG E 63’s Active Parking Assist can parallel park by itself, stopping and changing direction automatically. The S7 doesn’t offer an automated parking system.

Model Availability

The Mercedes AMG E 63 comes in sedan and station wagon bodystyles; the Audi S7 isn’t available as a station wagon.

Economic Advantages

Insurance will cost less for the AMG E 63 owner. The Complete Car Cost Guide estimates that insurance for the AMG E 63 will cost $945 less than the S7 over a five-year period.

The AMG E 63 will cost the buyer less in the long run because of its superior resale value. The IntelliChoice estimates that the AMG E 63 will retain 48.19% to 49.83% of its original price after five years, while the S7 only retains 45.93% to 46.21%.
