BMW iX3 - traction? - fullbreakfast
Hi there

Hello - I’m new here and had a question if anyone has got thoughts.

We are in the market for a used EV and it’s down to the iX3 or Mercedes EQC. Generally we prefer the iX3, but it’s rear wheel drive not 4 wheel and we live on a hill, so a bit concerned about traction when it gets to icy winter conditions. Does anyone have experience with this model and could comment?

Thanks very much for any help.

Regardless of fuel type, FWD, RWD or 4wd, the most important part of a vehicle in slippery conditions are the tyres.

A RWD car with brand new winter tyres will perform better on slippery roads than a 4wd on summer tyres with 2mm of tread.

No experience of either.

But, I am a self employed window cleaner working in various places around Aberdeenshire, including some very rural areas. In nearly 16 years I could count on one hand the amount of times I've felt four wheel drive would be of any real benefit.

Unless the hill you mention is very steep and/or generally ignored by the council re gritting and plowing, whether or not the car had four wheel drive wouldn't be a factor for me.

Not sure you would have the option on either of your choices, but "appropriate" tyres are much more important to me. By that, I don't just mean "all season" or "winter", but also not being ridiculously wide and ridiculously low profile.

I don't think the 4wd on the Merc would make much difference. It's not a 'proper' 4wd with diff locks and low ratio gears so is probably more of a performance and handling thing. I think it makes sense to have it on an EV to get the power down better, but it's not going to turn it into an off roader.

I suppose one issue quite specific to EVs is that they often come with 'special' tyres that are supposed to improve efficiency and reduce wear. What this really means is that have a harder compound and lower rolling resistance. Combine that with the extra weight of the batteries and the very accessible torque and I think you'll have a vehicle that is very hard to drive in snow and ice.

As suggested above, all season tyres will help a great deal, but hauling nearly three tonnes (in the case of the Merc) up and down an icy hill is not going to be much fun.
