Haven't been published yet. It took about a year for the Model S to get tested, so I'm guessing late fall or early winter for Model X test results. FWIW, it also hasn't been tested yet by EuroNCAP or by IIHS; IIHS has still never tested the Model S, so I'm not sure if they'll continue their position of "Teslas are low volume luxury vehicles not worth testing." (Presumably they'll test the Model 3?)
