I assume most of the autocrossers here trailer their vehicle to the autox and back, but I am curious what effect the actual event has on range. Say you start off with a full charge, what is the difference in range that it claims when the event is over? I plan on purchasing a Model S and there is of course no information on that for that vehicle at autocrosses yet so I ask here about Roadster experience on the matter just to get a general feel for what to expect. I hope to get the 300 mile battery pack. Since I enjoy autox, I would like to run the Model S at a few events, but I don't have a trailer. It looks like my local autox group does about half of the events at venues that are around 50 miles from me and the other half are at about 100 miles from me. If the charge / range burns down very quickly at an autox, it might not be feasible until I can find a way to trailer the car to / from events, but I hope I could make it out there and back. Also, I hope that charging stations will be a little more common here on the east coast once I get through the waiting line and the car is delivered to me... a short charge after an autox might be enough to get back home if the range is a little short after an event. So what reduction in range do the Roadster autocrossers experience for an event and what do they think about the distance I would have to cover before and after the event? Thanks!
