VarioCam Plus.
VarioCam Plus is a two-in-one engine
concept for adjusting the intake
camshafts and switching the lift of
the intake valves. The system first dif ferentiates bet ween
driver inputs that typify normal, everyday
driving and those inputs that demand
maximum performance. The electronic
engine management system then

imperceptibly adapts valve operation
to the prevailing conditions. This results in instant acceleration and
extremely smooth running.
In short, VarioCam Plus provides

extraordinary power with comparatively
low fuel consumption.

Integrated dry-sump lubrication.
Integrated dr y-sump lubrication ensures
a reliable supply of oil even when a sport y
driving st yle is adopted and the vehicle is
experiencing powerful lateral acceleration.
It also has additional cooling functions. The oil tank is located in the engine, there
-
by eliminating the need for an external oil
tank which saves both space and weight.
To reduce power losses and increase
efficiency, an electronically controlled oil
pump supplies the lubricating points
inside the engine as and when required.
This results in optimum supply of oil,
lower fuel consumption and reduced
emissions.
