Couldn't do much in fear of getting pulled over, but did an acceleration from around 50km/h to 110km/h. Didn't detect any drop off in acceleration up to that speed, the problem was it covers that gap in nothing, it felt instant probably due to the fact my insides moved from my front to back – it is mind blowingly fast. (I had a 2019 performance 3 and it was definitely noticeable faster both on 0-100 and the 50-110).
Suspension felt fine – definitely not as harsh as old model 3 performance. Didn't really have the opportunity to try out the different modes on the public roads but I reckon it would be awesome on a track day. The seats are brilliant, the bolster is crazy good, you don't have that lateral movement you had with the old M3P, the seats are a huge improvement.
