models, it ’s no different. The 6- cylinder
boxer engine, positioned low down at the
rear
of the car, succeeds in uniting t wo
characteristics that are normally mutually
exclusive – performance and efficiency.
Only by doing so is it possible to increase
power output whilst simultaneously
reducing fuel consumption and
CO
2 emissions.
At the heart of all this are intelligent
efficiency-enhancing measures such as
the auto start/stop function and direct
fuel injection (DFI).
And then there’s the crucial weight

is comparatively low fuel consumption
and a long service life.
Both engines are also equipped with
VarioCam Plus – a two-in-one engine
concept for adjusting the intake cam -
shafts and switching the lift of the intake

ration, exceptional smooth running
performance and an extraordinary
level of tractive power with a compara -
tively low level of fuel consumption.
