What does the 4.2 V8 TDI gain?
It is a twin-turbo diesel V8 with substantial torque headroom. It responds strongly to a measured map on standard hardware.
Can the E-Hybrid version be remapped?
Yes, working on the combustion engine's ECU. We do it with particular care so the change does not disturb the electric system.
How does this differ from the other Cayenne entries?
This covers the 958 generation specifically. Our history records the model under several designations, so check the others too.
