Friend of mine just had his standard Model S serviced recently and had a P85 loaner for a week. He was really impressed with the effortless acceleration which was noticeably quicker than the standard model, especially in the 0-40 mph range. At one point he briefly got up to 80 mph and noticed the car start to shudder and realized that it was governed to not exceed that speed. Anyone else have this experience? I assume that speeding with the P85 may be too hard to resist for some.
