Musk outlines cost-cutting plan for Boring Co: cheaper, faster tunnel digging

Published

on

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.

Tesla Sweden responds to car magazine’s claims that Model 3 has deficient brakes

The company stated that it would be examining the two Model 3s that were used in the magazine’s test.

Tesla Sweden has responded to a car magazine’s claims that the new Model 3 sedan has “deficient” brakes. The all-electric sedan was subjected to the publication’s tests, and its braking distance was reportedly found to be lacking. 

The car magazine’s tests

As noted in a report from Swedish car magazine Teknikens Värld, the new Model 3 Long Range’s braking distance proved subpar when it was tested, with the vehicle reportedly having a braking distance of a whopping 133.2 feet (40.6 meters). The magazine claimed that it repeated the test with another Model 3, and its results were only 5 feet (1.5 meters) better. 

The magazine noted that this was unacceptable since an acceptable braking distance is 124 feet (28 meters), which also happens to be the Model 3’s braking distance when it was tested by Edmunds in the United States. The publication also stated that the Volkswagen ID.7 Tourer, which is equipped with drum brakes at the rear, had a braking distance that’s 16 feet (5 meters) shorter in its tests. 

Tesla Sweden’s response

Tesla Sweden responded to the car magazine’s claims, stating that the all-electric sedan’s alleged braking performance was not consistent with the company’s data, nor does it align with the Model 3’s safety ratings. The company also noted that it would be examining the two Model 3s that were used in the magazine’s test. 

“In the latest braking tests with Model 3, which were conducted by Teknikens Värld 2021, a braking distance of 36.5 meters was measured for Model 3 RWD and 36.7 meters for Model 3 Long Range AWD, so these results are not recognized or consistent with our internal tests.

“We are examining the two specimens to find out why the braking distances differ. Safety is number one at Tesla. Model 3 comes with all safety features as standard. Independent crash safety organization Euro NCAP recently announced new crash results for cars tested in May 2025. Euro NCAP gives the upgraded Model 3 a 5 out of 5-star safety rating and an overall score of 90%, making Model 3 one of the safest vehicles tested under the latest and most stringent testing protocol ever,” Tesla Sweden stated.

Teknikens Värld digs its heels

While Tesla Sweden has responded to its allegations, the car magazine noted that it will nonetheless stand firm on its claim that the new Model 3 has deficient brakes. 

“The fact that the Model 3 previously passed the brake test is not relevant because today’s generation of the Model 3 is to be considered a new generation, as Tesla themselves often point out. Nor is the result in Euro NCAP relevant because they are different tests. We can therefore conclude that Tesla has deficient brakes on the new Model 3. It is good for everyone to know,” the car magazine wrote.

Trump pushes back on Elon Musk’s America Party, calls third-party move ‘ridiculous’

The clash marks a notable shift in the relationship between the two former allies.

United States President Donald Trump sharply criticized Elon Musk’s decision to launch a new political party, calling the move “ridiculous” and dismissing it as a distraction from the two-party system. The rebuke came shortly after Musk announced the formation of the “America Party,” aimed at disrupting what he calls the entrenched Republican-Democrat “Uniparty.”

Tensions escalate between Trump and Musk

The clash marks a notable shift in the relationship between the two former allies. Musk previously headed the Department of Government Efficiency (DOGE) under Trump’s administration, a position aimed at cutting federal spending. The alliance, however, appears to have fractured over policy differences, particularly Trump’s “Big Beautiful Bill,” which Musk notes will increase the country’s debt by $5 trillion.

Speaking to reporters on Sunday before boarding Air Force One, Trump said, “It’s always been a two-party system and I think starting a third party just adds to the confusion.” Hours later, he posted on Truth Social that Musk had gone “off the rails,” accusing him of promoting an “Electric Vehicle Mandate” that would have required all Americans to switch to EVs in a short timeframe. 

Trump emphasized that his latest tax bill deliberately excluded incentives for electric vehicles, saying Americans should be free to choose gasoline-powered, hybrid, or other new technologies without federal mandates, according to a report from the BBC.

Musk outlines goals for America Party

Musk has been open about his support for ending the EV tax credit, as long as the incentives for other industries like oil and gas are removed as well.. The CEO has adopted this stance for several years. He has also not supported the idea of a mandate that forces consumers to purchase electric cars.

Musk also stated that the newly formed America Party will focus on congressional races in 2025 and 2026, rather than fielding a presidential candidate in the near term. In his post on X, the Tesla and SpaceX CEO criticized both major parties for contributing to the national debt. He also noted that the Department of Government Efficiency’s work will be rendered useless if the US’ debt increases due to Trump’s Big Beautiful Bill.

Tesla’s sales in the United Kingdom rose in June, climbing 14% year-over-year to 7,719 units, as per data from the Society of Motor Manufacturers and Traders (SMMT). The spike in the company’s sales coincided with the first deliveries of the updated Model Y last month.

Model Y deliveries support Tesla’s UK recovery

Tesla’s June performance marked one of its strongest months in the UK so far this year, with new Model Y deliveries contributing significantly to the company’s momentum. 

While the SMMT listed Tesla with 7,719 deliveries in June, independent data from New AutoMotive suggested that the electric vehicle maker registered 7,891 units during the month instead. However, year-to-date figures for Tesla remain 2% down compared to 2024, as per a report from Reuters.

While Tesla made a strong showing in June, rivals are also growing. Chinese automaker BYD saw UK sales rise nearly fourfold to 2,498 units, while Ford posted the highest EV growth among major automakers, with a more than fourfold increase in the first half of 2025.

Overall, the UK’s battery electric vehicle (BEV) demand surged 39% to to 47,354 units last month, helping push total new car sales in the UK to 191,316 units, up 6.7% from the same period in 2024.

EV adoption accelerates, but concerns linger

June marked the best month for UK car sales since 2019, though the SMMT cautioned that growth in the electric vehicle sector remains heavily dependent on discounting and support programs. Still, one in four new vehicle buyers in June chose a battery electric vehicle.

SMMT Chief Executive Mike Hawes noted that despite strong BEV demand, sales levels are still below regulatory targets. “Further growth in sales, and the sector will rely on increased and improved charging facilities to boost mainstream electric vehicle adoption,” Hawes stated.

Also taking effect this week was a new US-UK trade deal, which lowers tariffs on UK car exports to the United States from 27.5% to 10%. The agreement could benefit UK-based EV producers aiming to expand across the country.
