2008 AUDI S4 suspension

General notes
320General notesExplanation of technical dataWhere not otherwise indicated or separately listed, all technical
data apply to vehicles with st andard equipment for the German
market. Other figures may apply for special versions and export
models.
Please note that the details listed in the vehicle's registration docu-
ments can be taken as correct.
Engine data
The figures for engine power output are determined according to
EU standards.
Performance figures
The performance figures were measured without equipment which
may influence performance, such as mudflaps or extremely wide-
section tyres.
Kerb weight (unladen weight)
These figures (kerb weight according to the currently applicable
version of EU Directive 92/21/EEC) apply to the vehicle with the tank
90% full, with no special equipment. The figures include an addi-
tional 75 kg to allow for the weight of the driver.
When towing a trailer, the gross vehicle weight may be exceeded by
up to 30 kg and the maximum rear axle weight may be exceeded by
up to 80 kg.
Maximum trailer weights
The maximum trailer weights are calculated in accordance with the
currently applicable version of EU Directive 92/21/EEC.
The figures for a trailer with brakes, on gradients up to 8% are appli-
cable only up to a maximum speed of 80 km/h (even though higher
speeds may be permitted when towing a trailer in some countries). The figures for a trailer with brakes on gradients up to 12%
and for
the weight of car and trailer on gradients up to 12% are applicable
up to a maximum speed of 100 km/h. This maximum speed must not
be exceeded even in countries where higher speeds are permitted.
Maximum draw bar loading
The vertical load exerted by the trailer drawbar on the ball joint of
the towing bracket must not exceed 80 kg.
In the interest of safety, we recommend applying the maximum
permitted draw bar weight. The stability of the trailer could be
adversely affected if too little weight is applied.
If the maximum permitted drawbar weight cannot be obtained, e.g.
when using small or light trailers, statutory regulations require that
the drawbar weight be at least 4% of the actual trailer weight (for
single-axle trailers or twin-axle trailers with an axle spacing less
than 1.0 m).
Dimensions1) The height of the vehicle depends on the tyres and suspension.
Take care not to damage low-mounted parts of the car (such as the
spoiler or exhaust system) on steep ramps, uneven road surfaces or
roadside kerbs, etc.
This applies especially when the vehicle is fully laden.Length
