Fuel tankRefill volume approx. 16.9 U.S. gallons/64 liters, including approx. 2.6 U.S.gallons/10 liters reserve.
Fuel qualityYour engine is designed to provide optimum performance and fuel economy using unleaded premium fuel with
an octane rating of 98 RON (93 CLC or AKI).
Porsche therefore recommends the use of these fuels in your vehicle.
Porsche also recognizes that these fuels may not always be available. Be assured that your vehicle will operate
properly on unleaded premium fuels with octane numbers of at least 95 RON (90 CLC or AKI), since the engine’s
“Electronic Oktane™ knock control” will adapt the ignition timing, if necessary.

weight and with a 50 % load without
additional equipment.
Transmission diagram
The transmission diagram is based on
standard values on the basis of a mean
effective scrub radius. Changes of the scrub
radius, the tire tolerance, wear and tear,
deviating country equipment and tire slip
have not been taken into account.
