911 Carrera 4
All 911 models can also be fitted
with the optional Sport Chrono
Package Plus. It offers even
sportier tuning of the engine and
chassis, and delivers even
greater driving pleasure as a
result.
Included in the package are a
digital and analogue timer, a ‘Sport’
select button, a performance
display and a personal memory
function in the new Porsche
Communication Management
(PCM). Also – when fitted in
combination with Porsche
Doppelkupplung (PDK) – the
‘Sport Plus’ button.
When the ‘Sport’ button on the
centre console is selected, the
EMS SDI 3.1 engine management
system enhances the engine
response. A modified throttle
map relates the pedal angle in
the footwell to a much wider
Euphoria.

angle of opening on the throttle
valve. Throttle response is
significantly more immediate,
and in the higher gears, a
hard rev-limiter helps protect
the engine under acceleration.
The optional Porsche Active
Suspension Management (PASM)
also switches to ‘Sport’ mode
for harder damping and more
direct steering, and, therefore,
better road holding.
A hard rev-limiter is also applied
in the automatic mode of the
optional PDK, while gearshift
points are delayed until the upper
rev range. The shift times are
shorter, the gear changes sportier.
At low rates of deceleration –
even with high engine speeds –
the system initiates a swifter
brake-induced downshift. In
manual mode, gear changes
are faster and more dynamic.
In ‘Sport’ mode, the trigger
threshold for PSM is raised
for increased longitudinal and
lateral dynamics. Agility is
enhanced under braking for
corners with PSM enabling
greater manoeuvrability under
braking and exit acceleration,
especially at low speeds.
For maximum dexterity, PSM can
be set to standby while the car is
still in ‘Sport’ mode. For safety,
it is set to intervene automatically
only when ABS assistance is
required on both the front wheels.
In combination with PDK, the Sport
Chrono Package Plus has two
additional functions that are
activated by pressing the Sport
Plus button, to take driving to
an even sportier level.
‘Launch Control’ is used, for
example, on the track to achieve
the best standing start possible –
a racing start.
