I'm curious how the 85D is going to compare against the regular 85. Any guesses? It seems like the 85 performance gap vs P85 is in the low range. Like the kW output is limited below 20 mph. How then is the 85D slightly faster 0 to 60? Are they going to free up some more low end power for the AWD? Does the higher oomph start to affect it before 60 mph like it does for the higher top speed? Is it going to be slightly faster then the listed specs like we've seen in past cars? All questions I have when trying to decide on S85 vs S85D vs inventory P85.
