The rear seatbelts optional on the AMG 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 RS 5 Sportback doesn’t offer inflatable seatbelts.

The AMG 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 RS 5 Sportback doesn’t offer a driver alert monitor.

Both the AMG E-Class Sedan and the RS 5 Sportback 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, blind spot warning systems, rearview cameras, available lane departure warning systems, around view monitors and rear cross-path warning.

The Mercedes AMG E-Class Sedan weighs 440 pounds more than the Audi RS 5 Sportback. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts.

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 AMG E-Class Sedan its highest rating: “Top Pick Plus” for 2019, a rating granted to only 55 vehicles tested by the IIHS. The RS 5 Sportback has not been tested, yet.

The front and rear suspension of the AMG E-Class Sedan uses air springs for a smoother, controlled ride than the RS 5 Sportback, which uses coil springs. Air springs maintain proper ride height and ride more smoothly.

The AMG E-Class Sedan has a standard 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 RS 5 Sportback’s suspension doesn’t offer adjustable shock absorbers.

The AMG 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 AMG 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 RS 5 Sportback doesn’t offer a load leveling suspension.

The AMG 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 RS 5 Sportback doesn’t offer drift compensation steering.

For a smoother ride and more stable handling, the AMG E-Class Sedan’s wheelbase is 4.5 inches longer than on the RS 5 Sportback (115.7 inches vs. 111.2 inches).

For better handling and stability, the average track (width between the wheels) on the AMG E-Class Sedan is 1.6 inches wider in the front and .3 inches wider in the rear than the track on the RS 5 Sportback.

The AMG E 63 S handles at 1.01 G’s, while the RS 5 Sportback pulls only .97 G’s of cornering force in a Car and Driver skidpad test.

The AMG E-Class Sedan 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 5 Sportback doesn’t offer a remote starting system.

Unlike the driver-only memory system in the RS 5 Sportback, the AMG 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 AMG E-Class Sedan’s standard easy entry system raises the steering wheel, making it easier for the driver to get in and out. The RS 5 Sportback doesn’t offer an easy entry system.

The AMG E-Class Sedan’s standard power windows have a locking feature to keep children in the rear seat from operating them, but the driver can still raise and lower all of them with the lock engaged. Audi does not offer a locking feature on the RS 5 Sportback’s power windows.

If the windows are left open on the AMG E-Class Sedan the driver can close them all at the outside door handle or from a distance using the remote (remote must be aimed at door sensor). On a hot day the driver can lower the windows from a distance using the keyless remote. The driver of the RS 5 Sportback can’t use the remote to operate the windows.

The AMG E-Class Sedan’s power window, power lock, power mirror and cruise control switches are lit from behind, making them plainly visible and easier to operate at night. The RS 5 Sportback’s cruise control switches are unlit, making them difficult to find at night and operate safely.

Heated windshield washer fluid is standard on the AMG E-Class Sedan to defrost the washer nozzles and quickly clear ice and frost from the windshield without scraping. The RS 5 Sportback doesn’t offer heated windshield washer fluid. Its standard heated washer nozzles will defrost the washer fluid but not the windshield.

To help drivers see further while navigating curves, the AMG E-Class Sedan offers optional adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle. The RS 5 Sportback doesn’t offer cornering lights.

A power rear sunshade and manual rear side window sunshades are optional in the AMG E-Class Sedan to help block heat and glare for the rear passengers. The RS 5 Sportback doesn’t offer a rear or rear side window sunshades.

Both the AMG E-Class Sedan and the RS 5 Sportback have standard heated front seats. The AMG E-Class Sedan also offers optional heated rear seats to keep those passengers extremely comfortable in the winter. Heated rear seats aren’t available in the RS 5 Sportback.

The AMG 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 RS 5 Sportback doesn’t offer a house-current electrical outlet.

The AMG E-Class Sedan’s optional Active Parking Assist can parallel park by itself, stopping and changing direction automatically. The RS 5 Sportback’s automatic parking system requires operating the brakes and transmission to safely park.
