Does anyone know what the horsepower is for a Model S 75D both pre- and post the July 1 / 17 "new software and hardware 0-60 update ?" I remember hearing that the model s had 691 hp, (and then some controversy where someone tested it and it had far less ?) but haven't seen horsepower rating since. Does anyone know the horsepower ratings for the 75, 90 and 100 ? and possibly historical model s models as well ?
