Porsche Cayenne Turbo - VarioCam Plus

VarioCam Plus

VarioCam Plus creates two engines out of one by steplessly adjusting the inlet valve timing and lift.

The system differentiates between normal road usage and performance driving, adapting seamlessly as driver inputs change. All functions are automatically controlled by the engine management system. All you experience is responsive acceleration and ultra-smooth running characteristics. Inlet valve timing is steplessly adjusted. To improve response when starting from cold, for example, VarioCam Plus selects the higher lift setting and retards valve timing.

At medium PMS and minimal load, the valve lift is lowered and timing advanced to minimize fuel consumption and emissions. At low engine speeds in particular, VarioCam Plus significantly improves fuel economy. To achieve maximum power and torque, the valve lift is raised.

Overall, the system provides greater performance with relatively modest fuel consumption.

Standard on the Cayenne S, Cayenne GTS and Cayenne Turbo.

Variable valve timing

The V6 engine in the Cayenne features variable valve timing on both inlet and exhaust. The camshaft phase angles are continuously varied by the engine management system via rotary-vane adjusters.

On the Cayenne S Hybrid, the inlet valve timing is continuously adjusted.

The key benefits include better fuel economy and lower emissions. It also helps to generate greater power and torque – even at low engine speeds.

Standard on the Cayenne and Cayenne S Hybrid.
