For enhanced safety, the front and middle seat shoulder belts of the Mercedes AMG E 63 have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision. The Audi S6 doesn’t offer pretensioners for the middle seat belts.

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 S6 doesn’t offer inflatable seatbelts.

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 S6 doesn’t offer a driver alert monitor.

The AMG E 63 has standard Mercedes-Benz Emergency Call, which uses a global positioning satellite (GPS) receiver and a cellular system to get turn-by-turn driving directions, remotely unlock your doors if you lock your keys in, help track down your vehicle if it’s stolen or send emergency personnel to the scene if any airbags deploy. The S6 doesn’t offer a GPS response system, only a navigation computer with no live response for emergencies, so if you’re involved in an accident and you’re incapacitated help may not come as quickly.

Both the AMG E 63 and the S6 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, all wheel drive, traction control, electronic stability systems to prevent skidding, daytime running lights, blind spot warning systems, rearview cameras, rear cross-path warning and available lane departure warning systems.

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 S6 doesn’t offer a remote starting system.

If the windows are left open on the AMG E 63 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 S6 can’t use the remote to operate the windows.

To help drivers see further while navigating curves, the AMG E 63 offers optional adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle. The S6 doesn’t offer cornering lights.

When the AMG E 63 is put in reverse, the passenger rearview mirror tilts from its original position. This gives the driver a better view of the curb during parallel parking maneuvers. Shifting out of reverse puts the mirror into its original position. The S6’s mirror doesn’t automatically adjust for backing.

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 S6 doesn’t offer a house-current electrical outlet.
