The safe bet has the fancy new
powertrain sending power to the rear wheels, though all - wheel - drive is not entirely out of the question.
Not exact matches
If the front of the vehicle is on ice and the
rear is on pavement, the all -
wheel - drive system can
send all the torque the
powertrain can produce
to the
rear, putting
power where the driver needs it.
However, the other idea is
to almost mimic a traditional BMW
powertrain setup by putting the electric motor up front but
sending the
power through a fixed - ratio gearbox and an electric propeller shaft (basically a driveshaft)
to send power to the
rear wheels.
