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 RS 7 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 RS 7 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 RS 7 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 RS 7 doesn’t offer a driver alert monitor.

Both the AMG E 63 and the RS 7 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.


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 43 more horsepower (603 vs. 560) and 111 lbs.-ft. more torque (627 vs. 516) than the RS 7’s standard 4.0 turbo V8. The AMG E 63’s 4.0 turbo V8 produces 74 lbs.-ft. more torque (627 vs. 553) than the RS 7 Performance’s standard 4.0 turbo V8.

Fuel Economy and Range

On the EPA test cycle the AMG E 63 S Station Wagon gets better fuel mileage than the RS 7 (16 city/23 hwy vs. 14 city/24 highway).

In heavy traffic or at stoplights the AMG E 63’s engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. The engine is automatically restarted when the driver gets ready to move again. (Start/Stop isn’t accounted in present EPA fuel mileage tests.) The RS 7 doesn’t offer an automatic engine start/stop system.

The AMG E 63 has 1.3 gallons more fuel capacity than the RS 7 (21.1 vs. 19.8 gallons), for longer range between fill-ups.

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 RS 7 (3). This means the AMG E 63 produces up to 16.5 pounds less smog-producing pollutants than the RS 7 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 an eight-speed automatic is available for the RS 7.

The AMG E 63’s launch control uses engine electronics to hold engine RPM’s precisely in order to provide the most stable and rapid acceleration possible, using all of the available traction. The RS 7 doesn’t offer launch control.

Tires and Wheels

For better traction and acceleration, the AMG E 63 has larger rear tires than the RS 7 (295/30R20 vs. 275/30R21).

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 RS 7 doesn’t offer drift compensation steering.

Passenger Space

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 RS 7.

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 RS 7’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 RS 7 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 RS 7 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 RS 7 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 RS 7 doesn’t offer an automated parking system.

The Mercedes AMG E 63 comes in sedan and station wagon bodystyles; the Audi RS 7 isn’t available as a station wagon.
