The Boring Company Unveils Electric Tunnel Hauler Using Tesla Model 3 Components
Liner Truck 3 moves 22,000-pound concrete segments without anyone in the tunnel.
The Boring Company has introduced a new tunnel-hauling vehicle built around Tesla Model 3 battery packs and drive units, designed to transport heavy concrete segments without any personnel underground.
What Happened
Liner Truck 3, unveiled via The Boring Company's official X account on August 7, 2026, is an all-electric vehicle purpose-built to move precast tunnel segments—each weighing more than 22,000 pounds—to the cutting face of the company's Prufrock boring machines. The truck operates remotely from The Boring Company's Global Operations Control Center in Texas as part of its Zero-People-In-Tunnel strategy. An earlier prototype was previously tested at the Bastrop, Texas research tunnels, and a factory tour showed an employee piloting a loaded liner truck using a PlayStation controller. Liner Truck 3 appears to be the production version of that concept now entering daily use.
Why It Matters
The Boring Company is currently operating multiple Prufrock machines in Nashville for the Music City Loop project, which has accelerated since February, while also expanding its Vegas Loop network on a near-monthly basis. Keeping concrete segments flowing to the cutting face is critical—any idle time for the boring machine represents a major cost inefficiency. By using Model 3 components already proven in passenger vehicles and the existing Vegas Loop fleet, The Boring Company can leverage shared supply chains and manufacturing scale across Musk's industrial ventures.
The Bottom Line
Liner Truck 3 marks another step in The Boring Company's push to automate tunnel construction while relying on Tesla-sourced hardware. Whether this component reuse strategy expands further into TBC's equipment lineup remains the next question for observers of both companies.
