Elon Musk pegs SpaceX BFR program at $5B as NASA’s rocket booster nears $5B in cost overruns
At the same time as NASA’s overrun-stricken Space Launch System (SLS) continues to limp towards its continuously delayed launch debut, now tentatively expected no earlier than (NET) 2021, SpaceX is forging ahead with the development of an equivalently capable launch vehicle known as BFR, comprised of a spaceship (BFS) and booster (BFB).
During a September 17th update to the next-gen SpaceX rocket’s steady progress, CEO Elon Musk offered a rough cost estimate of $5B to complete its development – no less than $2B and no more than $10B. According to NASA’s Office of the Inspector General (OIG), Boeing – primary contractor for NASA’s SLS “Core Stage” or booster – is all but guaranteed to burn through a minimum of $8.9B between 2012 and the rocket’s tentative 2021 launch debut.
NASA is finally (officially) acknowledging that EM-1, the maiden launch of SLS, will slip until at least June 2020. Sources tell us to expect another slip to 2021, official or not.https://t.co/CYf9SqbhBY

Originally contracted in 2014 to complete SLS booster development, production, and preparation by 2018 at a cost of $4.2B, Boeing has overrun its budget by a bit less than 50% (up to $6.2B) and overshot its scheduled launch debut by more than 2.5 years. Per an October 10th audit of the SLS booster program, NASA OIG has reasonably concluded that Boeing will pass that $6.2B expenditure estimate – meant to last until 2021 – in December 2018, meaning that at least an additional $2.7B will be required from NASA between now and 2021 if SLS is to have a chance at launching that year.
In other words, compared to Boeing’s first serious 2014 contract for the SLS Core Stages – $4.2B to complete Core Stages 1 and 2 and launch EM-1 in Nov. 2017 – the company will ultimately end up 215% over-budget ($4.2B to $8.9B) and ~40 months behind schedule (42 months to 80+ months from contract award to completion). Meanwhile, as OIG notes, NASA has continued to give Boeing impossibly effusive and glowing performance reviews to the tune of $323 million in “award fees”, with grades that would – under the contracting book NASA itself wrote – imply that Boeing SLS Core Stage work has been reliably under budget and ahead of schedule (it’s not).

The “Satisfactory” Stuff
In reality, Boeing has not once been under budget or ahead of schedule during any of 6+ NASA performance reviews.
“Boeing should have received a “satisfactory” rating for [two review periods]; a “good” rating for [one review period]; and an “unsatisfactory” rating (no award fee) for [the 2017 review period].”
Instead, NASA has given Boeing three “Very Good” (nearly perfect) reviews and three “Excellent” (perfect) reviews over the last 6 years, ultimately dispersing $323M of pure-profit “award fees” thanks to those grades, while the OIG firmly disputes Boing’s worthiness for at least $65M of that sum.
It is pretty pathetic when the only response that @BoeingSpace can muster via @BKingDC at its #politicospace PR effort in response to a damning @NASA_SLS report by @NASAOIG is to dump on the Saturn V – a rocket that actually flew – and worked – half a century ago. https://t.co/daN91bzwpC

Boeing – recently brought to light as the likely source of a spate of egregiously counterfactual op-eds published with the intention of dirtying SpaceX’s image – also took it upon itself to sponsor what could be described as responses to NASA OIG’s scathing October 10th SLS audit. Hilariously, a Politico newsletter sponsored by Boeing managed to explicitly demean and belittle the Apollo-era Saturn V rocket as a “rickety metal bucket built with 1960s technology”, of which Boeing was the core stage’s prime contractor.
At the same time, that newsletter described SLS as a rocket that will be “light years ahead of thespacecraft [sic] that NASA astronauts used to get to the moon 50 years ago.” At present, the only clear way SLS is or will be “light years” ahead – as much a measure of time as it is of distance – of Saturn V is by continuing the rocket’s trend of endless delays. Perhaps NASA astronomers will soon be able to judge exactly how many “light years ahead” SLS is by measuring the program’s redshift or blueshift with one of several ground- and space-based telescopes.
Ultimately, this is a particularly effective bit of self-mockery in the context of rationale lately used by Boeing and NASA to shrug off the jaw-dropping Core Stage contract’s underperformance, missteps, schedule slips, and budget overruns, namely that building big, complex rockets is hard. NASA and Boeing, neither of which have any meaningful experience building big, complex rockets – aside from Saturn IB, Saturn V, and the Space Shuttle – thus should be given a break for reliably and dramatically underestimating the difficulties of doing so in the 21st century.
One of the most breathtaking things about the new SLS report is the response by NASA's Gerstenmaier. Essentially, he says, this a is a big, complex rocket. And it's hard to build this stuff.https://t.co/ou8SFhji6a

Simultaneously, Boeing and NASA still continue to act as if they are the foremost global experts of building extremely large rockets and continue to throw pile upon pile of taxpayer billions at overpromised attempts to prove as much. It’s no more than a masochistic dream to imagine what could have been or might be if NASA instead redirected those billions towards US aerospace companies with track records of success through fixed-cost contracts or straight-up private funding (SpaceX and Blue Origin, primarily), but it’s often hard not to at least think about the possibilities.

Elon Musk hints what Tesla’s new vehicle will be
After Musk’s post earlier this week, many considered the possibility that the Tesla CEO was potentially talking about the Roadster, which is slated for an unveiling (again) next month. Some considered the possibility of the Robovan, which was unveiled back in 2024.
Elon Musk hinted at what Tesla’s new vehicle will be just a day or so after he essentially confirmed the company is developing something that will eventually be available for consumers.
Earlier this week, Musk said that something “way cooler than a minivan” was on the way from Tesla after a fan posted on X that the company needed to build something for larger families. Requesting this type of vehicle has been a move of many Tesla fans over the years, but now, the urgency is even higher for this type of car because of the company’s decision to sunset the Model X.
Following reports of Musk’s plans to build something that will be cooler than a minivan, speculation consisted of what could possibly be on the way.
Tesla has teased a CyberSUV for quite a while, and there were even some clay models built by the company that were strategically placed in a promotional video.
After Musk’s post earlier this week, many considered the possibility that the Tesla CEO was potentially talking about the Roadster, which is slated for an unveiling (again) next month. Some considered the possibility of the Robovan, which was unveiled back in 2024.
However, a new post from Musk seems to indicate that it will be a new project altogether. After one follower of Musk’s said:
“If Tesla makes a car with 3 rows of seats, each with its own pair of doors so nobody has to climb over anybody else to get to their seat, they will create a baby boom the likes of which we haven’t seen in 80 years.”
Musk’s reply was simple but definitely shed more insight into the company’s plans, as he said:
“Noted.”
Musk’s simple one-word answer might be enough to essentially expect something large, like a full-sized SUV. This would be an incredible addition to the Tesla lineup, especially as the Model X is going away.

Even the Model X is not quite big enough, and not comparable to vehicles like the Chevrolet Tahoe, so a three-row, six-door SUV might be exactly what Tesla fans want.
It certainly does not sound like Tesla is planning to launch the Model Y L in the U.S., at least not exclusively, or use that car, which is currently built in China, to solve the needs of a larger family.
Tesla gives big hint that it will build Cyber SUV, smaller Cybertruck
It seems the time has certainly come for Tesla to answer the call of what consumers want. This has long been requested, and although the company’s sights are ultimately set on achieving full autonomy, there is still a need for larger families, and a full-size SUV could be a great addition for Tesla as it moves into the second quarter of 2026.

Tesla’s newest “Folding V4 Superchargers” are key to its most aggressive expansion yet
Tesla’s folding V4 Supercharger ships 33% more per truck, cuts deployment time and cost significantly.
Tesla is rolling out a folding V4 Supercharger design, an engineering change that allows 33% more units to fit on a single delivery truck, cuts deployment time in half, and reduces overall installation cost by roughly 20%.
The folding mechanism addresses one of the least glamorous but most consequential bottlenecks in charging infrastructure: getting hardware from factory floor to job site efficiently. By collapsing the form factor for transit and unfolding into an operational configuration on arrival, the new design dramatically reduces the logistics overhead that has historically slowed Supercharger rollouts, particularly at large or remote sites where multiple units are needed simultaneously.
The timing aligns with a broader acceleration in Tesla’s network strategy. In March 2026, Tesla’s Gigafactory New York produced its final V3 Supercharger cabinet after more than seven years and 15,000 units, pivoting entirely to V4 cabinet production. The V4 cabinet itself is already a generational leap, delivering up to 500 kW per stall for passenger vehicles and up to 1.2 MW for the Tesla Semi, while supporting twice the stalls per cabinet at three times the power density of its predecessor. The folding transport innovation layers logistical efficiency on top of that technical foundation.
Tesla launches first ‘true’ East Coast V4 Supercharger: here’s what that means
Tesla Charging’s Director Max de Zegher, commenting on the V4 cabinet when it launched, captured the operational philosophy behind these changes: “Posts can peak up to 500kW for cars, but we need less than 1MW across 8 posts to deliver maximum power to cars 99% of the time.” The design philosophy has always been about maximizing real-world throughput, not just peak specs, and the folding transport upgrade extends that thinking into the supply chain itself.
Posts can peak up to 500kW for cars, but we need less than 1MW across 8 posts to deliver maximum power to cars 99% of the time.
No more DC busbar between cabinets. Power comes from a single V4 cabinet to 8 stalls. Easier to install, cheaper, more reliable.

The network is expanding rapidly on multiple fronts. The first true 500 kW V4 Supercharger on the East Coast opened in Kissimmee, Florida in March 2026, followed closely by a new site in Nashville, Tennessee. A public Megacharger for the Tesla Semi launched in Ontario, California in early March, with 37 additional Megacharger sites targeted for completion by end of year. Meanwhile, more than 27,500 Supercharger stalls are now accessible to non-Tesla EVs from brands including Ford, GM, Rivian, Hyundai, and most recently Stellantis, whose Dodge, Jeep, Ram, Fiat, and Maserati BEV customers gained access in March 2026.
As Tesla pushes toward a denser, faster, and more open charging network, innovations like the folding V4 Supercharger reflect the company’s growing focus on deployment velocity, not just hardware performance. Getting chargers to the ground faster, cheaper, and in greater volume per shipment may ultimately matter as much as the kilowatts they deliver.

The Boring Company clears final Nashville hurdle: Music City loop is full speed ahead
The Boring Company has cleared its final Nashville hurdles, putting the Music City Loop on track for 2026.
The Boring Company has cleared one of its most significant regulatory milestones yet, securing a key easement from the Music City Center in Nashville just days ago, the latest in a series of approvals that have pushed the Music City Loop project firmly into construction reality.
On March 24, 2026, the Convention Center Authority voted to grant The Boring Company access to an easement along the west side of the Music City Center property, allowing tunneling beneath the privately owned venue. The move follows a unanimous 7-0 vote by the Metro Nashville Airport Authority on February 18, and a joint state and federal approval from the Tennessee Department of Transportation and the Federal Highway Administration on February 25. Together, these green lights have cleared the path for a roughly 10-mile underground tunnel connecting downtown Nashville to Nashville International Airport, with potential extensions into midtown along West End Avenue.
Music City Loop could highlight The Boring Company’s real disruption
Nashville was selected by The Boring Company largely because of its rapid population growth and the strain that growth has placed on surface infrastructure. Traffic has become a persistent problem for residents, convention visitors, and airport travelers alike. The Music City Loop promises an approximately 8-minute underground transit time between downtown and the Nashville International Airport (BNA), removing thousands of vehicles from surface roads daily while operating as a fully electric, zero-emissions system at no cost to taxpayers.
The project fits squarely within a broader vision Musk has championed for years. In responding to a breakdown of the Loop’s construction costs, Musk posted on X: “Tunnels are so underrated.” The comment reflected a longstanding belief that underground transit represents one of the most cost-effective and scalable infrastructure solutions available. The Boring Company has claimed it can build 13 miles of twin tunnels in Nashville for between $240 million and $300 million total, a fraction of what comparable projects cost elsewhere in the country.

The Las Vegas Loop, The Boring Company’s first operational system, has served as a proof of concept. During the CONEXPO trade show in March 2026, the Vegas Loop transported approximately 82,000 passengers over five days at the Las Vegas Convention Center, demonstrating the system’s capacity during large-scale events. Nashville draws millions of convention visitors and tourists each year, and local business leaders have pointed to that same capacity as a major draw for supporting the project.
The Music City Loop was first announced in July 2025. Construction began within hours of the February 25 state approval, with The Boring Company’s Prufrock tunneling machine already in the ground the same evening. The first operational segment is targeted for late 2026, with the full route expected to be complete by 2029. The project represents one of the largest privately funded infrastructure efforts currently underway in the United States.
