Musk outlines cost-cutting plan for Boring Co: cheaper, faster tunnel digging
One of the large reveals made by Tesla and SpaceX Chief Elon Musk at TED2017 was his plan to create a multi-layer high-speed tunnel infrastructure to support mobility by way of electric skates and Hyperloop tubes.
A key point that he drove home for the underground tunnel network was the integration of the system into cities.
“You have to be able to integrate the entrance and exit of the tunnel seamlessly into the fabric of the city. So, by having an elevator, sort of a car skate that is on an elevator, you can integrate the entrance and exits to the tunnel network just by using 2 parking spaces.”
Musk shared a video demonstrating how skate elevators would be integrated into city streets where they await vehicles looking to be transported through the underground labyrinth of tunnels. The serial tech entrepreneur envisions loading docks wherein vehicles would simply pull into the skate, get lowered into the tunnel network, and be sent along a slot car-like track at speeds of 200 km/h ( 124 mph). The Boring Company’s tunnel network won’t simply alleviate surface congestion, it will completely transform the way we move cars, people and freight, says Musk.
It is worth noting that The Boring Company and Tesla are under control of Musk, while the Hyperloop project has been open sourced, but with support from SpaceX.
Eliminating human drivers allows the skates to move at much faster speeds than human-controlled vehicles. Fixed routes within the tunnel network further improve safety beyond the dynamic nature of human-determined driving routes. The tunnel network is also infinitely scalable. “You can alleviate any arbitrary level of open congestion with a 3D tunnel network.” and that “There’s no real limit to how many levels of tunnels you can have.”, says Musk from TED2017.
The key barrier to creating tunnels today is the exorbitant cost. The recent 2.5 mile expansion to the Los Angeles subway system came at a cost of nearly $1 billion per mile. Musk and team at the Boring Company hope to cut the cost of tunneling by a significant amount by streamlining the tunneling process and reinventing the machines that help facilitate the digging.

Building Tunnels For Less
First, the team is looking to cut the diameter of the tunnels they dig, moving from the traditional tunnel diameter for passenger vehicles of 26 to 28-feet to a 12-foot standard diameter which would be sufficient for the Tesla skate. On the surface, this might not seem like a lot, but cutting the diameter by 50% cuts the cross sectional area by a factor of four. This is significant as the speed and cost of tunneling is largely driven by the amount of cross sectional area to dig. Being able to cut out 75% of the time associated with digging comes with enormous cost savings.
Second, the team plans to attack head-on the way tunneling machines currently dig. Traditional machines dig, slowly and incrementally, then stop to install reinforcements to support the newly exposed earthen walls. Musk and team are working to install the reinforcements continuously thus eliminating the need to pause operations. This integration is expected to increase the speed of the overall process by as much as 50%.

Finally, the team believes that current digging machines are nowhere near their power and thermal limits, and is looking to ‘jack up the power’ to the digging machines. Doing this, the team hopes to increase the speed by a factor of 4 or 5 on top of the other improvements being suggested by Musk.
Musk also revealed that The Boring Company has a pet snail named Gary who can currently travel at 14 times the speed of existing tunneling machines. While this is more a testament about how slow the boring process is than the amazing speed of Gary, it is a fun target for the team, to be able to build tunnels quicker than Gary can crawl, and continues the comedic spin on the new company.
These tunnels could be kept at or near a vacuum to reduce or eliminate air resistance for all the moving objects within it. Curiously, Musk shared that,
“To withstand the water table, you have to design a wall to be able to withstand 5 or 6 atmospheres. To go to vacuum, you only need to be able to withstand 1 atmosphere.”
It is clear that Musk is very excited about this new Boring Company. He indicated during his sit down at TED2017 that he spends 2-3% of his time on the project, noting that it’s essentially being run as not much more than an intern project with a used boring machine and a few people dedicating partial effort to it.

Elon Musk’s Starbase, TX included in $84.6 million coastal funding round
The funds mark another step in the state’s ongoing beach restoration and resilience efforts along the Gulf Coast.
Elon Musk’s Starbase, Texas has been included in an $84.6 million coastal funding round announced by the Texas General Land Office (GLO). The funds mark another step in the state’s ongoing beach restoration and resilience efforts along the Gulf Coast.
Texas Land Commissioner Dawn Buckingham confirmed that 14 coastal counties will receive funding through the Coastal Management Program (CMP) Grant Cycle 31 and Coastal Erosion Planning and Response Act (CEPRA) program Cycle 14. Among the Brownsville-area recipients listed was the City of Starbase, which is home to SpaceX’s Starship factory.
“As someone who spent more than a decade living on the Texas coast, ensuring our communities, wildlife, and their habitats are safe and thriving is of utmost importance. I am honored to bring this much-needed funding to our coastal communities for these beneficial projects,” Commissioner Buckingham said in a press release.
“By dedicating this crucial assistance to these impactful projects, the GLO is ensuring our Texas coast will continue to thrive and remain resilient for generations to come.”
The official Starbase account acknowledged the support in a post on X, writing: “Coastal resilience takes teamwork. We appreciate @TXGLO and Commissioner Dawn Buckingham for their continued support of beach restoration projects in Starbase.”
The funding will support a range of coastal initiatives, including beach nourishment, dune restoration, shoreline stabilization, habitat restoration, and water quality improvements.
CMP projects are backed by funding from the National Oceanic and Atmospheric Administration and the Gulf of Mexico Energy Security Act, alongside local partner matches. CEPRA projects focus specifically on reducing coastal erosion and are funded through allocations from the Texas Legislature, the Texas Hotel Occupancy Tax, and GOMESA.
Checks were presented in Corpus Christi and Brownsville to counties, municipalities, universities, and conservation groups. In addition to Starbase, Brownsville-area recipients included Cameron County, the City of South Padre Island, Willacy County, and the Willacy County Navigation District.

The Boring Company wins key approval for Nashville Music City Loop
The approval allows The Boring Company to use state-owned right-of-way along Tennessee’s highway system.
Tennessee Gov. Bill Lee announced that the Tennessee Department of Transportation (TDOT) and the Federal Highway Administration (FHWA) have jointly approved The Boring Company’s lease application and enhanced grading permit for the Music City Loop.
The approval allows The Boring Company to use state-owned right-of-way along Tennessee’s highway system, clearing a key hurdle for the privately funded tunnel project that aims to connect downtown Nashville to Nashville International Airport in approximately eight minutes, the Office of the TN Governor wrote in a press release.
“Tennessee continues to lead the nation in finding innovative solutions to accommodate growth, and in partnership with The Boring Company, we are exploring possibilities we couldn’t achieve on our own,” Gov. Lee said in a statement.
“The Boring Company is grateful for the leadership and hard work of federal, state, and local agencies in bringing this project to a shovel-ready point,” The Boring Company President Steve Davis said. “Music City Loop will be a safe, fast, and fun public transportation system, and we are excited to build it in Nashville.”
With lease and permitting approvals secured, The Boring Company will move forward with the Loop system’s construction immediately. The first segment of the Loop system is expected to be operational by the end of the year.
The Music City Loop will run beneath state-owned roadways and is designed to connect downtown Nashville to the airport, as well as lower Broadway to West End. The project will be 100% privately funded.
“The Music City Loop shows what’s possible when we leverage private-sector innovation and American ingenuity to solve transportation challenges,” said U.S. Transportation Secretary Sean Duffy. “TDOT’s lease approval will help advance this ambitious project as we work to reduce congestion and make travel more seamless for the American people.”
The Boring Company described the Loop as an all-electric, zero-emissions, high-speed underground transportation system that will meet or exceed safety standards. The Vegas Loop, for one, earned a 99.57% safety and security rating from the DHS and the TSA, the highest score ever awarded to any transportation system.

Tesla China extends its 7-year financing promotion once more
The move marks Tesla’s second extension of the program this year.
Tesla has extended its seven-year ultra-low-interest and five-year interest-free financing programs in China once more, pushing the offers through March 31, the end of the first quarter.
The move marks Tesla’s second extension of the program this year. The financing plan was first introduced on January 6 as a strategy aimed at offsetting higher ownership costs ahead of China’s planned 5% NEV purchase tax in 2026.
The original promotion was set to expire at the end of January but was extended to the end of February. This has now been extended again through March.
The repeated extensions reflect growing competitive pressure. Tesla’s 2025 retail sales in China totaled 625,698 units, representing a 4.78% year-on-year decline, as per data compiled by CNEV Post. That being said, this decline is partly caused by the Model Y’s changeover to its new variant in Q1 2025, which resulted in lower sales during the quarter.
In early 2026, the Model Y also lost its position as China’s top-selling EV in January to Xiaomi’s YU7, though this was also a month when Tesla primarily exported vehicles to foreign territories, which pushed local delivery numbers lower.
During January 2026, Tesla China exported 50,644 vehicles, roughly 1.7 times higher than the same month a year ago and more than 15 times higher than December’s level.
Tesla’s financing push has not gone unanswered. BYD this week introduced its own seven-year low-interest plan across its Ocean lineup and Fang Cheng Bao sub-brand, also valid through March 31. Other competitors including NIO, XPeng, Li Auto, and Geely Auto have already rolled out extended-term loan programs as well.
