Turbochargers.
The displacement of the new 911
models
has been considerably reduced with the
aim of cutting fuel consumption. That’s
because we more than most as a sports
car manufacturer bear huge responsibility.
Nevertheless, the power output of the
new engines has been significantly
increased. Responsible for that are the
turbochargers developed for the911
completely from scratch.
The drive system is a twin-turbo
configuration. Ithas two turbochargers
with one charge-air cooling for each
cylinder bank. Both turbos are
particularly compact and have been
optimally adapted to the displacement
and power output of the engine. This
construction minimises theinertia of the
drivetrain and improves responsiveness.
The new turbochargers leave the sceptic
s
in their wake and find a new destination:
unexplored levels of torque.
What looks technical on paper has an
unmistakably resonant sound. The sound
of a 911. And a performance that hits the
driver in an instant. In the form of direct
acceleration and visceral forward thrust.
Rather like a ‘thump’ in the back the
moment the engine unleashes its
unadulterated power.
Active air intake flaps.
The active air intake flaps in the front air
intakes act to reduce fuel consumption
during everyday trips and to achieve
superlative performance on sporty
drives. Already proven on the 918 Spyder,
the flaps close automatically while the
car is in motion and thereby reduce drag.
On demandor in SPORT, SPORT PLUS or
PSMSport mode, the flaps open and help
to provide optimum engine cooling.
This means that cooling air is supplied
only to the extent that it is actually
needed. That’s efficiency. Of the
intelligent kind.
