The X versions (I have an 85X) don’t really make much use of the extra motor, it’s there for traction control and a small boost in Sport mode but only works at speeds under (if I remember correctly) 20kph.
“The electric cars in the Enyaq iV family have a special Traction mode for driving on non-tarmac and slippery surfaces. All-wheel drive is again active from the moment you set off, remaining engaged up to a speed of 20 km/h.”
Most of the time the front motor isn’t used, even in Sport mode the drive power is split 70% rear, 30% front.
Please excuse spelling/typos. Apart from being a clot it turns out I had one on my cerebellum that's now causing various problems!
