I think I have just established the maximum "Practical" driving range for my Model S Signature P85. Just got home from a round trip from Coto de Caza to Rancho Mirage to visit friends. Then went from their home to Jackalope Ranch Restaurant in Indio, then back to their home via El Paseo in Palm Desert and finally back home in Coto de Caza. Total miles = 246. Started out with a full Range Charge and 264 miles "Rated" range. 0" miles left on Estimated Range when we got home. Way too close for comfort, but the experience was interesting...
