LAS VEGAS — The Boring Company says its newest Prufrock tunneling machine has set a company speed record, boring further in a day than any of its earlier rigs and inching toward Elon Musk's long-running goal of digging faster than a snail can crawl.
The record run, logged on an active alignment, reflects a string of refinements to Prufrock's cutterhead, power delivery and the "continuous mining" approach that lets the machine excavate and install tunnel segments in one motion rather than stopping to swap between the two. Faster boring is not a vanity metric for the company — it is the single biggest lever on cost, because tunneling expense is dominated by time.
Speed Is the Whole Strategy
The Boring Company's founding pitch was that tunnels are too slow and too expensive to build, and that attacking the dig rate directly would unlock cheap underground transit. Each incremental gain in meters-per-day compounds across a project, trimming labor, financing and equipment costs. That is why the firm keeps iterating Prufrock rather than settling on a fixed design.
The speed work is showing up in the field. The company's flagship Vegas Loop keeps adding stations, expanding a network that already shuttles convention-goers beneath the Strip in Tesla vehicles.
