It looks like they changed a few things - acceleration, top speed, etc. to reach that number. I wish I could opt in for a slightly slower 90D with a longer range.My 90D X is giving about only 80% of Rated Mileage (I do have 22" wheels") and I cannot see how a 200 RM 60D to be practical. A 180 mile real world driving range will make me very nervous to take it on a SF to LA trip even though we have an extra SC at Buttonwillow now.
I agree, though. The real world range of the 60D is going to be such that there will likely be a lot of "in-app purchases" on road trips.
