With Tesla having AP, EAP, FSD, Version 9, Version 10 and MCU1 and MCU2 the permutations are getting quite big. We help answer what each version gets.
Tesla have run two versions of autopilot, the original mobileye version, sometimes known as AP1, and the subsequent Tesla version which was originally called Enhanced Autopilot, and laterly reduced tojust Autopilot and Full Self Driving.
To add a little extra confusion, Tesla have also had 3 versions of their hardware, the original HW2, later revised to HW2.5 which included some additional redundancy to the wiring, and the latest version HW3. Not only that, the Model 3 also includes an interior camera although for now, this makes no difference to the operation.
Tesla have promised to upgrade owners with older versions of the AP hardware (vrom version 2 onwards) to that needed to run the full self driving software if the option was purchased. There is some emerging evidence that even the EAP features are now struggling to perform on the early hardware, and Tesla have removed the option to upgrade some early cars to FSD (and as a result get the hardware upgrade from MyTesla. Considering these cars are now up to 3 years old, its unlikely Tesla want to revisit these older cars unless the owners have already purchased the FSD capability such is the increasing cost of the upgrade.>
While Tesla have been keen to suggest that all cars built since their version of Autopilot came out in late 2016 would support autopilot and they would offer free upgrades to anyone should they need it, Tesla have started to release features that do not work on all hardware versions, much to the annoyance of some owners although its primarily HW2 owners who are missing out, a double blow for those that bought their car new as they had to wait for nearly a year for any Autopilot features to be delivered.
While Tesla have called HW3 the 'FSD hardware', and it is said to have twice the computing power of HW2.5, the autopilot features are the same across all versions. What we suspect is happening is the software at times runs out of processing capacity and a situation may not be handled as well under the earlier versions compared to HW3. Tesla are said to still be optimising the code for HW2.5 and we can expect a jump in performance if not features when this happens. The problem Tesla have is maintaining backward comparability as even HW2 were sold as having everything needed for Full Self Driving. While upgrades are starting to take place for some cars who have the FSD option, we suspect the real challenge will be in the performance of regular Autopilot features as they already seem to be struggling.
Tesla have had a number of MCUs over the years. With the exception of very early screens, there is MCU1 used up until about March 2017 and MCU2 which has been in production since then. The MCU is totally separate to the autopilot hardware and have the performance of one is not dependant on the other. The table below refers to European cars once they have V10 installed, although the results are correct in most countries.
