That's according to a Tweet from Tesla CEO Elon Musk today, and he also said that the 0-60 and quarter-miles times for the Model X P100D will improve by 0.1 seconds. The Model S P100D will have a 10.6-second quarter-mile time, down by that same 0.1 seconds. Tesla won't have to install any new motors or anything to get the better performance, either. "This is purely a software optimization," Musk said, and it applies to all P100D vehicles produced to date. The Model S P100D starts at $134,500; the Model X P100D at $135,500.
Looks like the Model S P100D Easter egg will allow it to do 0 to 60 mph in 2.4 sec and a 10.6 sec 1/4 mile via software update next month— Elon Musk (@elonmusk) November 16, 2016
Model X numbers should also improve by 0.1 sec on 0 to 60 and 1/4 mile— Elon Musk (@elonmusk) November 16, 2016
