That RWD Wheee

[JamieGeek]

This is just confirming something the car does that my prior EVs and PHEV did.

My 3 previous plugins have all been FWD cars and when slowing down via regen if a front wheel lost traction....wheeee you'd feel like you're on ice (even if its 80F out and sunny...hit a pothole or some other thing that causes a traction wheel to lose grip and....).

Twice now in the past two days the same thing has happened on my RWD California Route 1: Driving along, slowing down during regen and one of the rear wheels loses grip....wheee. In my two cases: 1) was turning to go up a driveway and the car was at a goofy angle causing a wheel to come off the ground and 2) slowing down to go over a short bridge with a significant arch (the "bridge" is basically asphalt over a pipe).

Not complaining as I was kind of expecting this behavior from the car. (Yes during regen ABS does NOT kick in.)

This post is just a FYI for people so they don't freak and think "my car is broken".

I would think that it is much more difficult for this to happen on AWD versions as you'd have to get two wheels off the ground.

Thought that title meant you'd be talking about what happens with your bladder when Co-Pilot gets confused. ?

I think you are right. I don't notice that issue very much now that I am driving an AWD EV.

Sorry to resurrect an older thread, but seeing this got me thinking of my 1st Gen Chevy Volt which had this problem when driving in LOW--if a wheel lost traction during deceleration because of a pothole or whatever it would immediately cut off the regen, letting the car "coast" for a moment before it kicked back in. Strangely, this was NOT present on the 2d Gen Volt. I thought there was something wrong with my 1st gen, but found out from GM that they programmed the stability control system to stop regen whenever the system was triggered (they told me it had something to do with how the system would only use friction brakes to regain control). I wonder if they changed the programming in the 2d gen because it didn't have the same issue. Maybe Ford could do the same.
