I had an interesting thought I wanted to pose as a question. What if in 2014 when the Model X is rolled out you have the option of spending $10,000 to get (a) the Performance edition with an 85 kWh battery OR (b) a 110 KWh battery with a 0-60 time of 5.3s and an extra 60 miles of range (315 miles total after Model X "penalty")? If you could only choose one or the other which would you choose? For me I think the extra range and the slight bump in performance would be worth more to me then the insanely fast 0-60 performance. The only thing that would change my mind is if the Performance edition looked much more aggressive (like an M-series or AMG).
