What happens when Mercedes adds a hybrid drivetrain to its largest sedan?

#3. It's safety gadgets a-go-go!

Other than the hybrid power train, the biggest changes to the 2010 S-Class range are a host of high-tech safety features that debuted in the 2010 E-Class, including a Pre-Safe Brake system that can automatically apply 100 percent braking power to prevent a crash; Attention Assist, which monitors steering input and 70 other driving parameters to detect signs of driver fatigue; and Night View Assist Plus, which uses a windshield-mounted infra-red camera to extend visibility by 500 feet and highlight pedestrians in the path of travel. Exterior design tweaks include a revised front grill and bumper, and LED taillights that do away with the previous model's body-color-matched inset pieces.
