With the single motor variants, the front end gets a little lively under hard acceleration, mostly because of the lack of 400kg of engine under the bonnet to pin the wheels to the road. Not sure I would call it vibration but the steering wheel gets a lot of movement on it at that time. Is that what you mean or is yours more specific?

How does your car not have an "engine under the bonnet"?

The front and rear tires deform differently under acceleration due to the difference in wheel width.
This would be more pronounced if the inflation pressures are not correct.
Is anyone who is running same widths front and rear experiencing the issue?

I took mine (2022 LRDM) into the Toronto space about this issue. They said there was nothing wrong with the car and, per the PS Forum, it’s a trait of the car - leave it the PS forum to define what is an is not a problem 😂🥲 I also reported it to the Montreal space. They seem to be taking the issue more seriously as the vibration under acceleration is more pronounced with winter tires. In Quebec winter tires are mandatory 4 months per year. They said they are talking to Polestar HQ about it but no resolution as of yet.

Did you use "winter wheels"?
