Engine management
Sport mode of the Audi RS4
To accentuate the sporty character of the RS4, the
driver can switch Sport mode "on" of "off" using a
special switch.
Depending on steering wheel type, the spor t
program button is fitted in different locations.
In vehicles equipped with the RS sport steering
wheel, the Sport program button is located in the
left steering wheel spoke; in models equipped with
a multifunction steering wheel, it is located in the
centre console.
When Sport mode is activated, an indicator lamp
comes on in the dash panel insert.
Sport mode is deactivated when the ignition is
turned off.
Accelerator position
When the Sport program button is pressed the
following in-vehicle functions are activated:
– more direct accelerator pedal response
– improved lateral support function of the driver's
seat
– more sporty exhaust system set-up

Accelerator pedal function
(throttle progression)
When Sport mode is activated, the engine becomes
more responsive. At the same time, the characteris-
tic curve of the accelerator pedal is modified in the
engine control unit. This means that, in Sport mode,
the requested engine torque is higher than in
normal operation in the same accelerator pedal
position.
In addition the comfort-oriented "soft" engine
torque curve is suppressed. As a result, the engine
responds immediately to pressure on the accelera-
tor pedal.
