Introduction
Infinitely variable perfection
For the first time in this vehicle class, Audi
offers the infinitely variable "multitronic"
automatic gearbox for all front-wheel drive
versions.
The architecture of motion
Performance and smooth running
The engine programme of the new Audi A4
includes two petrol engines of a completely
new design, with aluminium housings.
The 2.0 litre 4-cylinder in-line engine with
96 kW (130 PS) and the 3.0 litre V6 with
162 kW (220 PS) fulfil the EU 4 emissions
standard.
A high degree of running smoothness is
achieved via balancer shafts.
The new light alloy running gear
With the four-link front axle, each wheel is
controlled by four aluminium transverse links.
The pivot bearings are also made from the
same light alloy.
The trapezium link rear axle for the quattro
drive system is also used in the front-wheel
drive models of the Audi A4.

The aero-floor
not only contributes to improved aero-
dynamics.
It was also possible to reduce the noise level
by approx. 3 dB (A).
The engine compartment noise insu-
lation does not form part of the aero-
floor. Part of the additional costs generated by the
aero-floor could be compensated by dispens-
ing with certain panelling components as
well as by dispensing with PVC protection of
the underside of the vehicle. The latter is of
advantage during recycling.The aero-floor was designed so as to guaran-
tee ground clearance and resistance to stone
impact and to prevent accumulation of dirt,
stones and snow.
