SafetyESC The
Electronic Stability Control (ESC) helps keep the vehicle traveling in
its intended direction by utilizing ABS, the traction control of ASR and
the electronic brake force distribution of EBD. Specifically, when ESC
detects loss of traction, it automatically adjusts the throttle and
applies the brakes to help "steer" the vehicle where you intend to go.
Braking is automatically applied to each wheel: at the outer
front wheel to mitigate oversteer, or the inner rear wheel to mitigate
understeer.
Safety Belt Pre-tensioners and High Impact
Crumple Zones
Inside, the Audi safety systems prepare for the worst once the brake
assist system is engaged. The safety belt pre-tensioners are activated
for front seat passengers and lock the safety belts in place. This is
intended to help keep passengers in the safest position in the event of a
collision. When prevention isn't enough, the combination of crumple
zones and high-strength steel helps deliver a tremendous level of
protection for the driver and passengers. Crumple zones, at the front
and rear of the vehicle, are designed to dissipate
the energy
and force of a collision by deforming upon impact. The high-strength
steel used in and around the occupant cell is designed to protect the
integrity of the passenger compartment and those within
it.
Six
Airbags The six
standard, second-generation airbags provide an additional measure of
safety. They include front-impact airbags for the driver and passenger
and are designed to help
protect the head. Seat-mounted,
side-impact airbags for the front seat occupants are designed to help
protect the thorax in a collision. And the side-curtain airbags offer
front and rear occupants head protection in the event of a side
collision or rollover.
Innovative Braking
System Audi has
implemented a number of ingenious features to help maximize braking
effectiveness. In wet conditions, the brake disc wiping system gently
pulses the brakes to help dissipate water buildup. Keeping the discs as
dry as possible helps promote the most effective braking. Additionally,
the brake assist system is able to detect an attempt at full
braking and apply full stopping power when required. The
advantage is that braking distance is significantly reduced.
