Tesla announces HW4 Plus with doubled memory — will HW4 follow HW3 to the grave?
During Tesla’s Q1 2026 earnings call, CEO Elon Musk revealed that Tesla is planning an “AI4.1 or AI4 Plus” upgrade to its self-driving computer that doubles the RAM from 16 gigabytes to 32 gigabytes per chip — taking the total system memory to 64 gigabytes.
The announcement came on the same call where Musk confirmed (or rather reconfirmed after backing away from the admision last year) that HW3 “simply does not have the capability” for unsupervised FSD.
For the millions of Tesla owners currently driving HW4 cars, the timing raises an uncomfortable question.
