I really, really hope there is a more affordable option with maximum range, even if acceleration to 60 is more than 6 seconds. That's like saying the best battery option will run you an additional $30k...Here's my completely speculative, wishful thinking:
Model 3
60: $35,000 + $1,200 destination, 6.3 sec, 320i competitor, 225 mi range (first deliveries 8/2018)
60D: $40,000 + $1,200 destination, 5.8 sec, 328i competitor, 230 mi range (first deliveries 5/2018)
85D: $50,000 + $1,200 destination, 4.8 sec, 340i competitor, 290 mi range (first Signature deliveries 12/2017)
P85D: $65,000 + $1,200 destination, 3.8 sec, M3 competitor, 265 mi range (first Signature deliveries 12/2017)
