Both the S5 and AMG C-Class Sedan have child safety locks to prevent children from opening the rear doors. The S5 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 C-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 S5 has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags help 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 C-Class Sedan doesn’t offer a front passenger side knee airbag.

Earlier warning of stopped traffic, traffic signals, dangerous road conditions, weather, or accidents, can keep driver's safer and prevent crashes. The S5 has standard Car-to-X Services, a system that seamlessly communicates important warnings to the driver about impending danger, if they're available. Car-to-X Communication costs extra on the AMG C-Class Sedan.

The S5’s standard lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane and gently nudges the vehicle back towards its lane. A lane departure warning system costs extra on the AMG C-Class Sedan.

Both the S5 and the AMG C-Class Sedan have standard driver and passenger frontal airbags, front and rear side-impact airbags, driver knee airbags, side-impact head airbags, front 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, post-collision automatic braking systems, daytime running lights, blind spot warning systems, rearview cameras, rear cross-path warning, driver alert monitors and available around view monitors.

For better ride, handling and brake cooling the S5 has standard 19-inch wheels. Smaller 18-inch wheels are standard on the AMG C-Class Sedan.

The S5 has a standard automatic front and rear load leveling suspension to keep ride height level with a heavy load or when towing. The S5’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 AMG C-Class Sedan doesn’t offer a load leveling suspension.

For a smoother ride and more stable handling, the S5’s wheelbase is 1.2 inches longer than on the AMG C-Class Sedan (114 inches vs. 112.8 inches).

In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The S5 Premium Plus/Prestige has standard headlight washers to keep headlight output high. The AMG C-Class Sedan doesn’t offer headlight washers.

Both the S5 and the AMG C-Class Sedan have standard heated front seats. The S5 Prestige also has standard heated rear seats to keep those passengers extremely comfortable in the winter. Heated rear seats aren’t available in the AMG C-Class Sedan.

The S5 (except Premium) offers optional massaging front seats in order to maximize comfort and eliminate fatigue on long trips. Massaging seats aren’t available in the AMG C-Class Sedan.
