VarioCam Plus is a variable valve timing system on the inlet side which also features two-stage valve lift. This allows smoother running with comparatively efficient fuel consumption and low emissions – yet with greater power and torque.

This two-in-one engine concept seamlessly adapts in response to driver input. The result is instant acceleration and extremely smooth running.

The timing of each valve is steplessly and electrohydraulically controlled by means of a rotary vane adjuster.

For optimum responsiveness during the warm-up phase, VarioCam Plus will select the higher valve lift setting and retard valve timing. At medium revs and low engine loads, the lower valve lift setting is selected and timing advanced in order to reduce fuel consumption and emissions. The higher lift setting produces high torque and more power output.
