Tesla is on the skin.
Company CEO Elon Musk has been promising fully autonomous driving with Tesla’s Full Self-Driving (FSD) package for years. However, in January, it turned out that older Teslas – those with HW3 hardware, as opposed to the new, HW4 hardware inside – don’t really support it, and never will.
This wouldn’t be a big deal if most HW3 Tesla owners hadn’t already bought the FSD package, which costs thousands of dollars (the price changed a lot over the years).

To appease these owners, Tesla previously promised a software version, called FSD V14 Lite, that will work on Teslas with HW3 hardware, but only in the US. Many, many warnings.

“Following the future release of FSD V14 Lite for HW3 vehicles in the US, we plan to expand V14 Lite to additional international markets. This update ensures that owners of HW3 vehicles will continue to benefit from ongoing software updates,” the company tweeted. “Since the international release is subject to several factors (the completion of technical verification, regional adaptation and appropriate regulatory approvals), we cannot provide exact dates yet, but we will provide continuous updates.”
The news coincides with the recent approval of FSD in the Netherlands, which may open the door for the software to be approved across the European Union. Tesla has been conducting supervised FSD tests across Europe; I have tried it in Croatia, I can say that it works well. But HW3 owners who bought the FSD aren’t too happy about being left out; others have already banded together and launched a claim site, asking for their money back.
Tesla’s FSD Lite is probably the way to please HW3 owners. It is worth pointing out, however, that FSD and FSD Lite are not the same, and in some ways, not close to each other. FSD should ultimately provide a truly autonomous driving experience, while FSD Lite gets some features of FSD but will likely remain a driving assistance package. And no, true FSD never came to HW3 cars; during Tesla’s Q1 2026 earnings call, Musk said that “Hardware 3 does not have the capability to achieve unsupervised FSD,” due to memory bandwidth, low camera resolution, and power processing issues.
Now, about those warnings. We don’t really know much about FSD V14 Lite, other than, as Tesla’s VP of AI Ashok Elluswamy said during the call, “it’s a distilled version of the same V14 software that we released in Hardware 4.” In addition, he said that the FSD V14 Lite will arrive in the US “at the end of June.” The international rollout will begin sometime after that, and is subject to regulatory approval, technical validation, and regional adaptation. Add to that Musk’s tendency to set unrealistic timelines, and it could be a long wait for HW3 Tesla owners in Europe and elsewhere.
On that earnings call, Musk also said Tesla will be offering the ability to retrofit older vehicles with HW4 hardware, but it’s unclear when that will begin, who will qualify, or whether it will incur additional costs to owners.
