The injection system was modified in order to
reduce exhaust gas and particle emissions. The main features of the basic engine are the
same as those of the familiar V6 TDI engine
with 132 kW (180 PS).
Power output and torque curve values could
be maintained under conditions which were
well within EU 3 limit values.

The additional cross member enables support
over a longer lever arm, which positively influ-
ences vibration and load cycle characteristics.
The aluminium cross member is bolted to the
body as well as to the rear subframe mount-
ings and, in addition to its supporting func-
tion for the gearbox mounting, serves as a
body-stiffening tunnel bridge.
Mechanical unit mountings
Running gear
The three-point mechanical unit mount-
ing is used for all engine/gearbox
combinations except those including
the 01V 5-speed automatic gearbox. A newly designed three-point mechanical unit
mounting is used in the new Audi A4.
The hydraulically damped engine mountings
(electrically-controlled version for diesel
engines) are fastened directly to the longitu-
dinal members via die-cast aluminium brack-
ets.
The gearbox mounting is effected by means
of a conventional rubber bearing on a body-
mounted aluminium carrier, which is pro-
duced according to the hollow sand casting
technique.
