Hi all, In the market for a Model S and just had a couple questions. I'm leaning towards a 75D and have driven both the 75D and the 100D models. Driving the 75D, I was NOT wowed by the acceleration. When I mentioned this to my OA, he said the 75D I drove did not have the newer motors or software update for the faster 0-60 update (4.2 Sec). The following day I drove the 100D (0-60 in 4.1) and was much more impressed with the performance. To anyone who has more experience in these cars than myself, does the updated 75D feel like the 100D acceleration? The 75D I drove was noticeably slower. Are there any other noteworthy differences between the 2 models besides the battery pack size? Not sure if the charging rate has been upped on the 75Ds.
