2015 PORSCHE 911 CARRERA 4S compression ratio

Drive 41
At Porsche, there are no conventions.
Forbidding free thought? That’s forbidden.
The only thing that mat ters is this
question: how can we become even
bet ter? Let ’s put it another way: can we
redefine the limits of engineering? Can
we reconcile apparent contradictions?
Yes, we can. With Intelligent Performance.
The new 911 answers questions about
the future of the sports car with a
quantum leap in performance. By
reducing fuel consumption, but not by
suppressing emotions. By following a
principle that has already changed
every thing once before: in 1974, with the
f i r s t 911
 Tu r b o. Developed completely from scratch, the
six-cylinder twin-turbo engines of the
911
Carrera and Targa 4 models with a
displacement of 3.0 litres embrace this
principle and perfect it in a forward-
l
ooking way. To be more precise:
tremendous acceleration force even in the
low rpm range is supplemented by the
engine map of a 911 Carrera with the high
rev limits t ypical of a sports car. In other
words, high compression and a high engine
speed combined with good modulation of
power output and surprisingly low fuel
consumption, thanks to the reduced
overall displacement.
Expressed in figures, this means an extra
15 kW (20 hp) of power, an extra 60 Nm
of torque and engine speeds of up to
7,500 rpm. And a considerable reduction
in fuel consumption of up to 13 %. The engine of the 911
Carrera and
911
Targa 4 models develops 272 kW
(370 hp). The maximum torque of
450 Nm is available from as low as
1
,700 rpm. With Porsche Doppelkupplung
(
PDK), the 911 Carrera can accelerate
from 0 to 62 mph in only 4.4 seconds
and reach a top speed of 182 mph.
The propulsive potential of the engine in
the S models, featuring upsized
turbochargers and independent exhaust
system, is even more impressive. It
generates a power output of 309 kW
(420 hp) and the maximum torque is a
might y 500 Nm, available from as low as
1
,700 rpm. With Porsche Doppelkupplung
(PDK) and Launch Control, the
We could sit back in the slipstream of our own tradition.

Engines.
911 Carrera S sprints to 62 mph in a
mere 3 .9 seconds. Top speed isn’t
reached until 190 mph.
What cannot be expressed in figures: the
legendary sound of a 911
six-cylinder
horizontally opposed engine. And the
experience is all the more intense for it.

1) Weight is calculated in accordance with the relevant EC Directives and is valid for vehicles with standard specification only. Optional equipment increases this figure. The figure given includes 68 kg for the driver and 7 kg for luggage. 2) Data determined in accordance with the measurement method required by law (Regulation [EC] 715/2007 as amended). The figures do not refer to an individual vehicle nor do they constitute par t of the of fer. They are intended solely as
a means of comparing different types of vehicle. Fuel consumption calculated for vehicles with standard specification only. Actual consumption and performance may vary with items of optional equipment. A vehicle's fuel consumption
and CO
2 emissions depend not only on its ef ficient use of fuel but also on driving st yle and other non -technical factors. The latest Porsche models with petrol engine are designed to operate on fuels with an ethanol content of up to 10 %.
