In an emergency stopping situation, many drivers don’t press the brakes with enough force to stop the vehicle in the shortest distance. The C-Class Sedan has a standard brake assist system to detect emergency braking situations (by how hard and how quickly the brake pedal is pressed) and then automatically apply maximum braking immediately in order to help prevent a collision. The G70 doesn’t offer a brake assist feature.

The C-Class Sedan stops shorter than the G70:

Unlike the driver-only memory system in the G70 3.3T/Elite/2.0T Manual/Prestige/Sport, the C-Class Sedan offers an optional 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.

If the windows are left open on the C-Class Sedan the driver can close them all at the outside door handle or from a distance using the remote. On a hot day the driver can lower the windows from a distance using the keyless remote. The driver of the G70 can only operate the windows from inside the vehicle, with the ignition on.

The C-Class Sedan’s rain-sensitive wipers adjust their speed and turn on and off automatically based on the amount of rainfall on the windshield. This allows the driver to concentrate on driving without constantly adjusting the wipers. The G70’s standard manually variable intermittent wipers have to be constantly adjusted.

A power rear sunshade is optional in the C-Class Sedan to help block heat and glare for the rear passengers. The G70 doesn’t offer a rear sunshade.

The C-Class Sedan’s optional Active Parking Assist can parallel park or back into a parking spot by itself, stopping and changing direction automatically. The G70 doesn’t offer an automated parking system.
