Looking at how the car behaves it definitely does do well on what is a damp circuit. However, one will notice there is an abundance of body roll. The car does put its power down well out of corners despite it being damp and appears very smooth (as it should with a world champion at the wheel). Additionally, only a single lap is done so how will the car behave under extended lapping? Well, if it were to go into limp mode or the brakes faded it would be safe to say BMW would not release the video.
It's nice to see BMW keeping track performance in mind with the M235i. As far as how it really performs, we will have to wait and see for when a third party gets their hands on it. So far, it appears to be shaping up well.
