Audi Q7 e-tron quattro 4M - e-tron Modes Explained

62
e-tron modes
EV mode
The EV mode prioritises electric drive mode. In this mode the
vehicle runs with the minimum possible CO
2
emission within the
e-range, provided that the driver's power requirements do not
exceed the capacity of the e-machine. The driver's power require-
ments are indicated to the system via the active accelerator pedal
(refer to page 18).
Hybrid mode
In Hybrid mode, the hybrid management system selects the most
favourable drive mode. The vehicle is operated as fuel-eciently as
possible beyond its pure e-range.
If Predictive Eciency Assist (PEA) is activated via the MMI and
route guidance is started, the e-tron Hybrid mode is set automati-
cally and once only in the driving cycle if the distance exceeds the
maximum electrical range of the vehicle. Taking into account the
navigation data, the system operates in such a way that the electri-
cal energy of the hybrid battery will ideally be used up when the
vehicle reaches its destination. This helps keep CO
2
emission to a
minimum.
BatteryHold mode
During vehicle operation, the hybrid battery charge is held at a
constant level. The vehicle runs in hybrid mode. This means that
both drives are active. Only a small proportion of the battery
charge is utilised. The battery charge is saved for later operation in
EV mode.
The downhill assist functions aids the driver on downhill gradients.
It is activated in selector positions D and S when the foot brake is
pressed or after the cruise control system is activated.
The gearbox selects a gear appropriate to the gradient. The task of
downhill assist is to maintain the reduced speed within the bounds
of its physical and drive limitations. It may be necessary to addi-
tionally correct the vehicle's speed with the foot brake.
Downhill assist
Downhill assist cuts out again as soon as the gradient lessens or
the accelerator pedal is pressed.
Downhill assist cannot overcome the physical limitations of the
vehicle and therefore cannot maintain a set speed in all conditions.
The driver must always be ready to apply the brakes!
e-tronmodes EV, Hybrid and BatteryHold can be freely selected
one after the other in a loop using the electric drive button E656
(EV button) or using the rotary pushbutton of the MMI.
The e-tronModi are adapted to meet country-specific legislation
and customer requirements.
