I thought I remember reading that earlier Autopilot production included fewer sensors and later they increased it to 12, is that true or do all Tesla produced since Oct 2014 have the same hardware?
October 2014 signature build. 12 sonar sensors, 1 forward camera. 4 sonar sensors forward, 4 backward and 1 in each fender facing sideways.
Since sometime in late September 2014: 12 ultrasonics, 1 forward camera, 1 forward radar (and the rear camera all cars have, it is not known if Tesla is using that camera in some way to assist Autopilot).
