I have ordered a Model 3 LR Dual Motor with delivery set to Dec 23-36. The sales rep that I talked to at the showroom mentioned that all cars manufactured in December will be made as a 2020 model year. She also mentioned that the new model could feature faster charging. When emailing her again about more details, she said "There is not current public information on the 2020 model now. Only internal email". I would like to know if anyone else has heard about these "faster charging rates" for the M3 2020.
