Boring Company Debuts Tesla-Powered Liner Truck 3 Tunnel Hauler

LAS VEGAS — The Boring Company has rolled out its newest piece of tunneling hardware, and it runs on parts pulled straight from a Tesla. Liner Truck 3, unveiled this week on the company's official X account, is a fully electric, remotely piloted vehicle built around Tesla Model 3 battery packs and drive units — and it is designed to keep crews out of the tunnel entirely.

Built From Tesla DNA

The vehicle's job is unglamorous but essential: hauling precast concrete tunnel segments to the face of the boring machine fast enough to keep it from idling. Each load tops 22,000 pounds, roughly the weight of a full cement mixer, and Liner Truck 3 shuttles that cargo between the surface staging area and wherever the Prufrock machine happens to be cutting. It offers 28 miles of range and a 12 mph maximum operating speed, numbers tuned for the confined, repetitive grind of tunnel logistics rather than the open road.

Reusing Model 3 batteries and drive units is a shrewd engineering shortcut. The powertrain is already validated for real-world reliability, and servicing draws on an existing, high-volume supply chain — the same components that move riders through the Vegas Loop now haul concrete beneath it. It is the clearest example yet of Tesla passenger-car hardware finding a second life in heavy industrial equipment across Musk's companies, a strategy on full display as the Loop keeps expanding with its newest Sahara Strip station.

Zero People In The Tunnel

Liner Truck 3 is piloted remotely from the Boring Company's Global Operations Control Center in Texas, extending the "Zero-People-In-Tunnel" approach the company has spent years building toward. An earlier ZPIT liner truck was tested at the company's Bastrop, Texas research tunnels, and a recent factory tour showed an operator flying a fully loaded truck with a game controller. Liner Truck 3 looks like the production-ready version of that idea — cleaned up and pushed into daily service.

Removing the driver from the tunnel is both a safety win and a throughput win. Concrete-segment delivery has long been one of the tightest bottlenecks in tunnel construction, and automating it lets the boring machine run closer to its true potential. The efficiency push comes as investors take the company more seriously, with the firm reportedly chasing a $20 billion valuation in a new funding round.

Digging In More Places Than Ever

The timing lines up with a company expanding on multiple fronts. The Boring Company now has Prufrock machines active or arriving in Nashville, where Music City Loop construction has been accelerating, and its Vegas Loop network keeps adding tunnel mileage on a near-monthly basis. Every one of those projects depends on getting segments to the cutting face quickly — exactly the bottleneck Liner Truck 3 was built to erase.

The debut, detailed by Teslarati, also hints at where this goes next. If Model 3 components can power a 22,000-pound underground hauler, the same reuse logic could extend across the rest of the Boring Company's equipment lineup and into other Musk-owned industrial hardware. For a company promising to make tunneling dramatically faster and cheaper, squeezing proven EV parts into purpose-built machines is a quietly powerful advantage — and a sign the Loop's build-out is only accelerating.
