Occupant protection
This is due to the large area impact carriers
located in the doors and the B-pillar which
deform in a pre-defined way.
They transmit the impact forces to the cell
structure.
The A2 is also equipped with Thorax lap
airbags as standard on the front seats.
These side airbags are located in the in the
seat backs and are always positioned so that
they can operate, regardless of the setting of
the seat.
In the M equipment level, the head airbag
system SIDEGUARD is also offered in addition
to the side airbag and the side impact
protection for the front and rear seats.
Front seatbelt pre-tensioners, belt force
limiters and the child seat securing system
ISOFIX for the rear seat bench are fitted as
standard in the basic model.

The Audi A2 is equipped with full-size airbags
as standard on the driver’s side and the
passenger side.
The layout of the airbag systems, including
the size of the bag, the characteristics of the
gas generator and the exiting speed of the
gas after ignition, was optimised and co-
ordinated with the aid of virtual development
and simulation tools.
This side structure is capable of absorbing
large forces with only a low impression depth
thanks to its use of two-chamber hollow
profiles and continuous frame-stays.
In addition the structure is supported by the
die-cast, one-part B-pillar, which is bonded to
the floor structure and the roof frame
assembly.
The strains that can occur during a crash are
below the bio-mechanical limits.
