Weight Distribution on Electric Cars.

[simongt]

Last night a colleague got himself stuck in a muddy car park in his EV.
We pushed him onto solid ground nae bother, but it was when I saw the front drive wheels failing to grip, it occurred to me that because the battery unit is under the floor of the passenger area of the car and therefore spread over a much larger area and the electric motor is much lighter than an ICE engine & gearbox, then there's no appreciable weight directly over the drive wheels to give any appreciable advantage unlike an ICE car.
Or am I missing something - ?

Could be, but any car can get stuck especially wide tyres designed for tarmac, not mud.

Theres no perfect solution for all scenarios.

Low and between the axles is ideal for most purposes, better than up front or even ahead of the front axle line, but may not be ideal in this scenario.

Selecting the appropriate driving mode would have limited both slip and torque and helped get your chum out. He needs to read the manual.

Reminds me of a friend of mine that was a copper
he said he had "rescued " lots of drivers that were stuck in ice/mud

They said he must have had extra driving training due to being a fully trained pursuit driver
which he wasn;t - he was "just " a normal copper driving around in a basic Fiesta
he just knew how to drive because his Dad taught him and he had a brain!

My Dad was a RoSPA observer and taught me to drive. I've regaled you good folk many times with tales of his teaching technique with me, but suffice to say I've nefer been daft enough to try and park a car on any unsuitable surface.

It is sometimes as simple as knowing where the drive wheels are and reversing into a parking space if the far end of it is downhill and icey

saw that once on a field used as parking to watch a car rally

I reversed in to keep the front drive wheels on good grass

several others went in the wrong way and the people who knew what they were doing had to pull them out

it's called thinking

My Viva, Capri, Cortina, TR7 and Carlton had no (traction) battery, and a petrol engine at the far end of the car from the driving wheels. Front engine RWD was the most common layout at one time.

And the 'old fashioned' tip of always leaving the car in gear when parked in case the handbrake fails.
Still do it instinctively even after fifty three years of driving - !

Wheel turned into the kerb.
