CNN article

The S-Class will have a radar-assisted braking system that detects objects ahead and applies the proper amount of braking even if the driver doesn't.

When sudden, firm braking is applied, the car's seat belts will automatically tighten and air cushions that support occupants in their seats will inflate. If an impact seems imminent, the car's side windows will close automatically.

Special infra-red headlights will illuminate the road in the dark, detecting obstacles more than 150 meters ahead and relaying them to a dashboard display.

Optional seats will automatically adjust the amount of back and side support according to driving conditions. The seats will also give back massages.

those sound pretty cool.
