The engineering of a 911 starts with its engine.
Two engines with Direct Fuel
Injection (DFI) and power output
of 345 horsepower and 385
horsepower. The optional Porsche
Doppelkupplung (PDK). Porsche
Communication Management
(PCM) with touchscreen and, on
request, a voice-control system.
All progressive technol ogies.
It would be so easy just to
sum up the meaning of i nner
strength . We, however, prefer
to get to the root of it.
All of the 911 Carrera and
911 Targa 4 models have Direct
Fuel Injection (DFI). So how does
this c ompare with standar d fuel
injection? The air/fuel mi xture
is prepared entirely in the
com bustion
chamber after
hav ing been
metered and
injected directly,
with
millisecon d precision.
From a technical perspective,
this means an accurate air/fuel
mixture and, therefore, optimal
com bustion. For the driver, it
means a distinct rise in po wer
and torque, and a distinct fall in
fuel con sumption and emissions.
Porsche Doppelkupplung
(PDK), available as an option,
is based on a development
that helped Porsche ra cing
cars in the 1980s to dominate
racetracks around the worl d.
PDK, with both a manual gearshift
and an automatic mo de , has
seven gears at i ts di sposal. It is
like having two gearboxes in one,
and two clutches. Whenever a
particular gear is engaged, the
next gear is always preselected.
Gearshifts,
th erefore, take place
within
hundredths of a second,
withou t any interruption in the
f low of powe r. In comparison wi th
conventional manual transmission,
PDK achieves a considerably
faster rate of acceleration for the
same rate of fuel consumption.
When compare d with t he
previous automatic transmission,
i t provides significantl y more
driving pleas ure, thanks to
improved responsiveness and
greater agility—with the same
degree of comfort at a reduced
rate of fuel consumption.
In com binati on with the Sport
Chrono Package Plus, PDK
has a choice of two additional
functions beyond “Sport”:
“ Launch Control,” for optimal
acceleration from a standing
start, and a “motorsport-
derived
gearshift strate gy,”
bringing
gearshift characteristics stra ight
from t he racetrack .
An additional
display on the steering
wh eel
notifies you whe n the
Sport,
“Sport Plus” and Launch
Control
functions hav e been enabled.
