Driving on inter-urban roads
The following phases are possible when driving
on inter-urban roads:
rapid acceleration (boost mode)
R
constant energy consumption
R

R
electric operation mode

A great deal of recovered energy may be avail-
able, depending on the route profile. This
reduces consumption and emissions.
Highway driving
During highway driving, fuel consumption and
emissions are favorably influenced in particular
by reduced power losses.
If the driver takes his/her foot off the accelera-
tor pedal in drive program E and a speed of
100 mph (160 km/h) is not exceeded, the com-
