If you do the math 70/85 * 270 (range for 85D) = 222. Now we all know that the 60 was more efficient and did better than 60/85 * 265 = 187. At 208 miles it was 21 better than "predicted" and now the S70D is 18 better than predicted. None of that made any sense to me then and it still doesn't. A few hundred pounds isn't going to make that much of a difference in highway range. The problem is the EPA range is a blended city/highway range but that still didn't make sense. On the Tesla website, the difference in highway range was more than the difference in EPA for a 60 and a 85 which makes sense. But still, the difference was not as great as you think. Unfortunately, all of this hand wringing is important because a lot of us are considering the S70D because the value proposition is so much better than before. But is the real highway difference only 30 miles or is is more like 50 since the EPA represents a blended city/highway number For me, I have a 85D that was confirmed last night (love the timing). I'm tall and I've never had a power liftgate before. So $500 change fee and I can save $1750 on tech and $1000 on pano roof. And then maybe $10k on the battery. Decisions decisions. So I need someone to drive a 70D on 3000 mile old tires (19s) at 70 mph and see how far you get. And I need that in the next week or so. TIA Would be helpful if Tesla could update the FAQ on range with 70D but I'm not sure I'd believe that anyway.
