Cayenne S DFI Engine

Cayenne S DFI Engine







On the new V8 naturally aspirated engine in the Cayenne S, the displacement has been increased by 0.3 liters to 4.8 liters with a compression ratio of 12.5. Engine power has been increased by 45 HP to 385 HP, while the torque is now 370 ftlb. (500 Nm) - an increase of +59 ftlb. (+80 Nm). Idling rpm is 580 rpm (550 rpm for AT with transmission range engaged) and maximum engine rpm is 6700. The new DME control unit EMS SDI 4.1 has been specially adapted to suit direct fuel injection and the modified engine specifications of the V8 naturally aspirated engine.

- DFI direct fuel injection.
- Intake system with variable intake manifold.
- Enhanced exhaust system.
- New sports exhaust system (optional, in conjunction with Tiptronic S).

Piston Recess







The piston recesses are specifically designed to suit the characteristics of the V8 naturally aspirated engine during late injection with the high pressure stratified charge ignition system and during the catalytic converter heating phase.

The increase in the compression ratio from 11.5 to 12.5:1 on the V8 naturally aspirated engine as a result of DFI serves to optimize both engine power and fuel consumption.
