I was browsing the EPA website earlier today, and noticed some interesting numbers for the S85, S85D, and P85D. First thing that struck me is that they had two versions for the P85D. The 2014 version, which is just called out as "2014 Tesla Model S AWD (85 kW-hr battery pack)" with no mention of the P85D model, was rated at 242 miles of range (with the same MPGe details as those on my Monroney sticker) whereas the 2015 version, called out properly as "2015 Tesla Model S AWD - P85D", is rated at 253 miles - which is what Tesla currently advertises: The next interesting thing is the power rating of the motors: It looks like the front motor in the 2015 version of the P85D was reduced to 164 kW (241 hp) from the 2014 version, which supposedly had 180 kW (220 hp). Tesla's website currently shows 221 hp for the front motor. The S85D correctly shows the two motors as 140 kW (188 hp) that Tesla advertises, however the S85 shows 270 kW (362 hp) whereas Tesla advertises 380 hp. And finally, instead of "All-Wheel Drive" for the 2015 P85D, the 2014 version stated "4-Wheel Drive". Perhaps because torque sleep was not implemented yet at the time? PS: apologies for the red bold font - it was really difficult to discern what I wrote from the EPA site's font.
