Tesla is once again causing discussion in the tech and car community: the manufacturer has officially confirmed that older vehicles will not be able to drive fully autonomously. Models with the so-called Hardware 3 (HW3), which has long been considered future-proof, are particularly affected. For many buyers who had hoped for software updates, this is a bitter setback – and raises questions about Tesla’s long-term strategy. Highlights - Tesla confirms: Hardware 3 is not sufficient for fully autonomous driving - Many buyers had relied on later software updates - Upgrade or vehicle replacement offered as a solution - First legal steps are already being prepared by customers Hardware limits slow down autonomous vision For years, Tesla had propagated the vision of its vehicles being able to drive fully autonomously via software updates. In particular, buyers of vehicles with Hardware 3, which has been installed since 2019, invested several thousand euros in the “Full Self-Driving” package (FSD). This hope has now been put into perspective. CEO Elon Musk confirmed in a conference call that HW3 “does not have the necessary capabilities” to enable so-called unsupervised autonomous driving. According to Tesla, the decisive bottleneck lies in the technical architecture: compared to the current Hardware 4, HW3 offers significantly lower memory bandwidth and computing power – key factors for AI-based driving decisions in real time. This makes it clear that the originally planned approach of implementing autonomous driving primarily via software updates is reaching its physical limits. The existing sensor and computing infrastructure is simply not sufficient for a system that is supposed to handle complex traffic situations completely autonomously. Upgrade instead of update: Tesla’s new strategy In response to the limitations, Tesla is planning various options for affected customers. These include discounted vehicle upgrades to newer models with Hardware 4 as well
