VarioCam Plus combines variable valve timing with two-stage lift on the inlet side. This results in smoother running, better
fuel economy and lower exhaust emissions. As well as greater top-end power and low-end torque.
This two-in-one engine concept seamlessly adapts in response to driver input. The result: instant acceleration and extremely
The variation in intake timing is steplessly controlled by means of an electro-hydraulic rotary vane adjuster at the head
of the corresponding camshaft.
To improve throttle response during the warm-up phase, VarioCam Plus selects high valve lifts with retarded valve timing. In the middle and low load ranges, low valve lifts with advanced timing reduce fuel consumption and exhaust emissions. High valve lifts generate high torques and maximum output.
