You guys are comparing P Model S to a non-P Model 3. Non-P cars, whether S or S, are a little sluggish off the line. My non-P Model S is the same way. Non-P cars just don't hit the ground the way P cars do.
I would disagree. I drove S75 and S85, both standard versions felt much faster from stop(0-30). 85D has even more oomph. I got those (non D) as loaners.
