VarioCam Plus is a variable valve timing system on the inlet side which also features two-stage valve lift. For excellent smooth-running performance, better fuel economy and fewer emissions. And greater power and torque.

The timing of each valve is steplessly and electro-hydraulically 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. For maximum power and torque, the higher lift setting is selected and the timing of the valves is advanced.
