At the same time the pretensioning seatbelts fire, removing slack from the belts. The S8 doesn’t offer a whiplash protection system.

The Phantom has a standard blind spot warning system that uses sensors to alert the driver to objects in the vehicle’s blind spots where the side view mirrors don’t reveal them. A system to reveal vehicles in the S8’s blind spot costs extra.

To help make backing out of a parking space safer, the Phantom has standard Cross Traffic Warning, helping the driver avoid collisions. Audi charges extra for rear cross-path warning on the S8.

Having a flat tire is dangerous, inconvenient and expensive. The self-sealing tires available on the Phantom can automatically seal most punctures up to 3/16 of an inch, effectively preventing most flat tires. The S8 doesn’t offer self-sealing tires.

The Phantom has active sway bars, which help keep it flat and controlled during cornering, but disconnect at lower speeds to smooth the ride and offer greater off-road suspension articulation. This helps keep the tires glued to the road on-road and off. The S8 doesn’t offer an active sway bar system.

Laser headlights, standard on the Phantom, produce their light by firing blue lasers through phosphorus, a process that uses one-half the power of the S8’s LED headlights. Laser headlights can have double the range of LEDs with a much smaller surface area.

The S8’s cornering lamps activate a lamp on the front corner when the turn signal is activated. The Phantom’s standard adaptive cornering lights turn the actual headlight unit up to several degrees, depending on steering wheel angle and vehicle speed. This lights a significant distance into corners at any speed.
