Efficiency-enhancing technologies.
Auto start/stop switches off the engine
when the driving speed falls below 7km/h
under moderate deceleration, such as
when you are approaching a red light. As
soon as you release the clutch or, with
PDK, depress the accelerator pedal, the
engine restarts – swiftly and smoothly.
In conjunction with Porsche Doppelkupplung
(PDK), a coasting function becomes
available where the situation allows.
The engine is decoupled from the
transmission to avoid deceleration
caused by engine braking. In this way,
optimum use is made of the vehicle’s
momentum, enablingit to coast for
longer distances.
Sports exhaust system.
It’s a first for any Porsche turbocharged
boxer engines, and it’s a technical
innovation. Available as an option for the
new 911, the sports exhaust system
features two catalytic converters and a
rear silencer, which lead into twocentrally
positioned tailpipes. For a look otherwise
more likely to be seen on the racetrack.
For impressive resonance and an intense
sports car sound – typical of the 911.
For 100 % Porsche. And for goose bumps
at the push of a button.
