Tesla Clarifies AP45 Misunderstanding: No HW4.5 in Current Models (2026)

Tesla Clarifies Hardware Confusion: No AI4.5, Just a Labeling Error

Tesla has addressed a recent misunderstanding regarding its vehicle hardware, specifically the Full Self-Driving (FSD) system. In an internal communication, the company confirmed that there is no HW4.5 (AI4.5) currently in customer vehicles, contrary to earlier reports. The confusion arose from a temporary mislabeling issue, where the option code "AP45" was mistakenly used in some internal systems and documentation.

The company quickly acted to clarify the situation, sending a message to sales advisors in North America, including the U.S., Puerto Rico, Canada, and Mexico. Tesla acknowledged that employees were receiving numerous questions and feedback from customers about the different hardware associated with FSD. Social media reports indicated that some customers were hesitant to place orders or even canceled their existing ones, awaiting more information.

According to Tesla, the "AP45" label was a result of minor formatting differences between manufacturing teams, not an introduction of a new FSD computer. This was a labeling issue, not an indication of a new or upgraded hardware platform. Tesla assured customers that all vehicles being delivered today are equipped with AP4, their latest and most advanced hardware for FSD (Supervised).

To prevent future misunderstandings, Tesla is updating all labels, option-code descriptions, and internal systems to standardize terminology. Sales advisors have been instructed to use updated talking points to provide consistent and accurate explanations to customers. Tesla emphasizes that there is no hidden upgrade or surprise compute bump, and customers can proceed with their purchases without worry.

For those considering a Tesla purchase, the company offers a referral program. By using the provided link, customers can receive three months of Full Self-Driving (FSD) when they buy a Tesla.
