Tesla Info: Technical hardware differences

Tesla have made a number of changes to the technology in their. This guide describes the technical differences between the key versions of Tesla hardware and supports our guide to the Functional differences between Tesla hardware versions


Tesla have run two broad versions of autopilot hardware, the original Mobileye version, sometimes known as AP1, and the subsequent Tesla version which was originally called Enhanced Autopilot (EAP), and latterly reduced to just Autopilot (AP) and Full Self Driving (FSD).

AP0 - No AP system

The first cars had no Autopilot hardware and on the early cars even parking sensors were an option later becoming standard as part of the technology pack. It was only when the Technology pack with convenience features came out that AP hardware started being included although at the time Autopilot was still some way off.

AP1 - Mobileye system

AP1 hardware was first introduced as part of the technology pack with convenience features and later became standard fit regardless with the introduction of the dual motor cars such as the 85D. Tesla bought in AP1 technology from Mobile eye and is based on their EyeQ3 hardware which is also used by a number of other makes of car for active cruise control, lane departure warning etc. Tesla pushed the capability of the EyeQ3 hardware further than anyone else and in part that was why Mobileye and Tesla fell out. Tesla essentially push technology to breaking point and that results in failures, Joshua Brown being the first fatality as a result of relying on the autopilot system beyond its capabilities. While Tesla do stress the versions are driver aids, they also promote full self driving and do little to ensure drivers use the systems correctly. This has set a pattern of behaviour of Tesla ever since, pushing beyond the capabilities of the hardware and software to give a 99.9% positive experience and hope the 0.1% of poor experience is not catastrophic.
