Tesla Faces Massive Hardware Upgrade Challenge to Enable Future Full Self-Driving
4/26/2026, 11:53:09 PM
Core Event: Musk Announces Need for Physical Upgrades to Enable Supercharged FSD
During Tesla’s earnings call, CEO Elon Musk said the company must physically upgrade millions of Hardware 3 vehicles to run a future Full Self-Driving (FSD) software that operates without human supervision, requiring microfactories in several major cities.
Background & Context: Evolution of Tesla’s Full Self-Driving and Hardware 3
Tesla’s FSD suite runs on dedicated hardware. Hardware 3, sold from 2019-2023, is the current platform. Owners have long sought confirmation that their cars can support a fully autonomous FSD version, which Tesla has not yet released.
Data & Statistics: Financials and Scale of the Upgrade
Tesla reported $1.4 billion in free cash flow and expanded its capital-expenditure budget to $25 billion, while the upgrade could affect millions of Hardware 3-equipped vehicles sold between 2019 and 2023. The retrofit could be expensive, though pricing is undisclosed. The $25 billion capex expansion was highlighted as a key line item for the upgrade effort.
Official Statements & Responses
Musk’s admission on the earnings call is the only formal statement on the upgrade plan; Tesla has not issued a separate press release or detailed the timeline.
Criticism & Opposition
Former engineers and owners have repeatedly “bugged” Tesla for a clear answer, warning that retroactive hardware costs could breach consumer expectations and raise legal concerns.
Conflicting Reports & Gaps
The company gave no timeline, cost per vehicle, or exact count of affected cars, and the advanced FSD software remains unreleased, leaving a gap between promised capability and existing hardware.
Why It Matters
Microfactory construction could consume a large share of the $25 billion capex, pressuring profitability and potentially inviting regulatory scrutiny.
What’s Next
The company may allocate part of the expanded capex to fund microfactory build-outs, and further earnings calls are likely to provide updates on timelines and cost estimates.
