The Panamera’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The CT5-V doesn’t offer pre-crash pretensioners.

Both the Panamera and CT5-V have child safety locks to prevent children from opening the rear doors. The Panamera 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.

A passive infrared night vision system optional on the Panamera helps the driver to more easily detect people, animals or other objects in front of the vehicle at night. Using an infrared camera to detect heat, the system then displays the image on a monitor in the dashboard and even aims one of the vehicle’s headlights in the direction of the person or object. The CT5-V doesn’t offer a night vision system.

To help make backing out of a parking space safer, the Panamera has standard Rear Cross Traffic Alert with automatic braking, systems which detect vehicles approaching from the sides and can automatically apply the brakes to prevent a collision. The CT5-V Manual doesn't offer automatic rear cross-traffic braking.

Regenerative brakes improve the Panamera’s fuel efficiency by converting inertia back into energy instead of wasting it. The CT5-V doesn’t offer a regenerative braking system.

Regardless of its engine, the Panamera’s engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution.
