I say that from looking at the range and efficiency values for a Model S 100D vs Model S P100D. There isn't much difference between these two models, other than larger more powerful motors in the P100D. The 100D has a longer range, and lower kWh/100 miles EPA efficiency ratings than the P100D. -------------- next part -------------- An HTML attachment was scrubbed...
