Granted, a tow hitch isn't exactly as sexy as the model's notable falcon-winged doors, but the upshot is that Tesla says the car will have the best aerodynamics of any vehicle its size, so that should help out that single-charge range a smidgeon. Tesla made the towing-capacity announcement in an e-mail, which we found on Cleantechnica.
Additionally, the Model X will have dual-mode all-wheel drive, in case anyone wanted to tow that boat down a dirt road. Early reservation holders will likely start getting their Model X EVs the in third-quarter 2015, and beta versions of the vehicle are currently being built for crash testing and other fun stuff. People who haven't yet made that reservation will be waiting until 2016 to get their SUVs, though.
The Model X, in some circles, is expected to make a pretty big splash. This summer, investment bank Morgan Stanley forecast that the Model X would be outselling the Model S sedan by the end of 2016.
