Hybrid Operating Modes

Hybrid Operating Modes

The Cayenne S Hybrid can operate in six special driving modes that are only available with a parallel full hybrid and make a decisive contribution to increasing fuel economy.
- Driving solely under electric power
- Boosting (addition of combustion engine and E-machine torques)
- Combustion engine powered driving with load point shift
- Coasting (unpowered gliding)
- Regenerative braking (recuperation; i.e. recovery of brake energy)
- Start Stop function

Various conditions that prevent the activation of a hybrid-specific driving mode may exist depending on the system. Limit and threshold values define these criteria. The following overview contains a selection of the most important reasons that prevent the combustion engine from switching off (engine stop vetoes):
- Driver setpoint torque, vehicle or engine speed too high
- Battery charging state too low or too high
- Engine/Catalytic converter temperature too low
- Battery too warm or too cold
- Gradient too steep
- Hood open (protection for workshop personnel)
- Driver's seat belt not fastened or driver's door open when selector lever in P or N position
- Engine diagnoses active (catalytic converter diagnosis, mixture adaptation)
- Vehicle electrical system power or air-conditioning performance too high
