Tales from a Tesla Model S that hit 400,000 miles in 3 years

Published

Tesloop, a Tesla-only intercity shuttle service for Southern California commuters, has reached another milestone with its Model S 90D. In a recent announcement, the company revealed that their Model S, dubbed eHawk, has passed the 400,000-mile mark, making it as one of the highest mileage Teslas in the world today.

eHawk entered service on July 2015, driving from city to city in Southern California and Nevada. By February 2016, the Model S 90D had logged its first 100,000 miles, and by August that year, the full-sized family sedan passed the 200,000-mile mark. In a recent blog post, Tesloop stated that roughly 90% of eHawk’s trips were driven using Autopilot, with Pilots (as the company refers to its drivers) only taking over active driving duties when needed. Tesloop’s Model S 90D currently travels an average of 17,000 miles per month. On the company’s recent post, Haydn Sonnad, Tesloop’s founder, expressed his optimism for the coming years.

“Vehicle connectivity is about to transform the car ownership and user experience. We are close to the point where increasingly sophisticated autonomous driving features and deep connectivity are coupled with electric drivetrains that last hundreds of thousands of miles, a whole new approach to mobility can be offered, that will transform the economics of car ownership and usage, while offering a greatly superior customer experience,” he said.

Over the past 3 years and through 400,000 miles on the road, eHawk has accumulated roughly $19,000 worth of maintenance costs, equating to about $0.05 per miles. This cost is broken down to $6,700 for general vehicle repairs and $12,200 for regularly scheduled maintenance. According to the company’s estimates, a Lincoln Town Car or a Mercedes-Benz GLS class would have accumulated maintenance costs of $88,500 ($0.22/mile) and $98,900 ($0.25/mile), respectively, had the vehicles been driven for 400,000 miles.

The Model S 90D’s high voltage (HV) battery unit was replaced twice under warranty since July 2015. The first battery HV battery replacement was at 194,000 miles, while the second was at 324,000 miles. Average battery degradation over the vehicle’s first 194,000 miles was around 6% with multiple Supercharger stops every day. Between 194,000 – 324,000 miles, the HV battery degradation was estimated at around 22%. According to Tesloop, this was likely due to the company’s practice of constantly charging eHawk to 95-100%, instead of Tesla’s recommended 90-95%. On its blog post, Tesloop shared Tesla’s reminder to the company after its first HV battery replacement. 

“Found internal imbalance in HV battery due to consistent supercharging to 100% from a low state of charge (SOC) without any rest periods in between. HV battery has been approved to be replaced. Also recommend that customer does not Supercharge on a regular basis and does not charge to 100% on a regular basis. We also recommend that the customer use scheduled charging to start charge 3 hours after end of drive at low SOC.”

Apart from its HV battery, Tesloop’s Model S 90D also had its front drive unit replaced under warranty at 36,000 miles. No issues with the vehicle’s drive units have emerged since. The Tesla-exclusive shuttle service also opted to upgrade the rear seating of eHawk to the executive seat option for maximum passenger comfort. According to the company, the seats have held up well over the thousands of passengers the electric car has transported over the years.

Considering the endurance showcased by its Model S 90D, Tesloop estimates that eHawk should be able to last another 600,000 miles over the next five years. If the vehicle achieves this, it would be the first Tesla Model S to reach the 1 million-mile mark.

Tesloop currently operates a fleet of Model S and Model X vehicles. One of its Model X, a 90D named Rex, also achieved its own milestone last month, after it hit 300,000 miles on the road since being deployed. When the all-electric SUV reached the 300,000-mile mark, its battery degradation was estimated at roughly 10%. Since achieving its milestone, however, Tesla has changed the vehicle’s rear drive unit.

Elon Musk’s next Uranium in Uranus merch is Boring Company’s weirdest tease yet

Elon Musk teased a glowing new Boring Company merch idea, complete with a Geiger counter.

Elon Musk teased the next piece of Boring Company merchandise on X Saturday, and it is exactly as unserious as fans of the company’s product history have come to expect. “The next @boringcompany merch will put Uranium in Uranus,” Musk wrote in a thread posted early Saturday morning. He followed up by explaining that the item would glow in the dark, “because otherwise how could you find it,” and that a Geiger counter would be sold separately as “an optional strap-on.”

Musk closed the thread with a line that doubles as a mission statement for the tunneling company’s merchandise arm: “It’s not easy coming up with something that is both outrageously unsellable and yet extremely popular.”

The Boring Company has built a small but consistent side business out of novelty items that start as jokes and end up selling out. The company’s Not-a-Flamethrower raised roughly $10 million in a few days back in 2018, moving all 20,000 units it produced. Its Burnt Hair perfume, priced around $100 a bottle, sold out fast enough that scalpers were flipping units on eBay for ten times the retail price. Boring Bricks, made from tunneling spoil, followed the same playbook of teasing a product on X months before it became real.

Musk has not said what the actual item will be, only that it involves uranium and glows in the dark. Given the pattern, that vagueness is probably intentional. Past merch announcements have started as one-line jokes and taken weeks or months to turn into an actual product listing on the company’s site, and there is no guarantee this one follows through at all.

The timing lines up with a period of real momentum for the Boring Company outside of the joke merchandise. The company said last week it plans to double the number of operational stations on its Vegas Loop by the end of the year, a target tied to a hiring push for drivers and operations managers. Prufrock-5, one of the company’s tunnel boring machines, also just wrapped a test tunnel in Bastrop, Texas, and is expected to relaunch on its next assignment in November.

Whether the uranium joke turns into an actual product remains to be seen. Musk’s post did not include a price, a shipping date, or even a name for the item, which has historically meant a Boring Company website page goes up quietly, password protected, sometime before an announcement.

NASA taps SpaceX for more astronaut missions as Boeing Starliner remains grounded

NASA just gave SpaceX a $946 million contract for three more astronaut missions through 2030.

NASA has awarded SpaceX a $946 million contract modification covering three more astronaut missions to the International Space Station, according to an announcement the agency published Friday. The award adds Crew-15, Crew-16, and Crew-17 to SpaceX’s existing Commercial Crew Transportation Capability contract, bringing the agreement’s total value to $5.92 billion across 17 flights.

SpaceX confirmed the award on X, writing that it was excited for Falcon 9 and Dragon to launch NASA’s Crew-15, 16, and 17 missions to the Space Station from Florida. The new missions cover ground, launch, in orbit, and return operations, along with cargo transport and a lifeboat capability while docked at the station, and the period of performance runs through 2030.

The award follows a notice of intent NASA issued in May, when the agency first signaled it would purchase up to six additional post certification missions from SpaceX. Teslarati covered that filing at the time, noting NASA cited technical issues and schedule delays encountered by Boeing as a driving factor. Friday’s contract modification locks in three of those six missions, with the remaining three left open for NASA to award later, potentially to Boeing if Starliner clears certification.

Boeing’s CST-100 Starliner has still not flown an operational crew rotation mission for NASA. The spacecraft’s most recent crewed test flight in 2024 ended without the astronauts returning aboard Starliner, and the company has spent the time since working through thruster problems. SpaceX President Gwynne Shotwell said this week that SpaceX is not retiring Crew Dragon today, for sure, while stopping short of committing to fly it past 2030.

Crew-12 is currently docked at the space station, and NASA has said Crew-13 is targeting a launch in the coming weeks. The newly awarded Crew-15 through Crew-17 missions extend SpaceX’s role as NASA’s primary way of getting astronauts to and from orbit well into the back half of the decade, regardless of what happens with Starliner or Starship in the meantime.

New drone video shows Tesla’s Optimus Factory reaching a turning point

New drone footage shows Tesla’s dedicated Optimus factory steel frame nearing completion at Giga Texas.

Tesla’s dedicated Optimus factory at Gigafactory Texas is closing in on a finished steel frame, according to drone footage posted Thursday afternoon by longtime site observer Joe Tegtmeyer. In the video, Tegtmeyer said structural steel assembly is now about five column grids away from reaching the building’s north perimeter beam, putting the primary skeleton in its final stretch roughly six months after Tesla broke ground on the North Campus site in late March.

Tegtmeyer’s footage shows concrete already going in on three upper floors while crews continue laying rebar and pouring grade beam footings at ground level. That kind of parallel work, steel rising at one end of the site while concrete sets at the other, is a scheduling approach Tesla used at the original Giga Texas building and appears to be repeating here to save time before the plant’s targeted 2027 production start.

Teslarati has tracked the building’s progress since Tesla confirmed construction was officially underway in May, when the first steel structure went up on what was then bare, reclaimed land. The facility is part of a more than 5.2 million square foot expansion of Giga Texas’s North Campus that Tesla has said will eventually run nearly the length of the existing vehicle factory, over 4,000 feet, while sitting somewhat narrower. Musk has pegged the long term output target at 10 million Optimus units a year once the line is running at full capacity, a volume that would dwarf the one million unit pilot line Tesla is standing up separately at its Fremont, California factory.

Tesla Giga Texas to feature massive Optimus V4 production line

The Texas facility sits alongside another major buildout on the same campus. Terafab, the joint Tesla and SpaceX chip fabrication plant that will eventually supply the silicon running Optimus units in the field. Housing robot assembly and chip production on the same grounds is a deliberate supply chain decision, cutting down on the shipping and lead time that would otherwise sit between the two.

Tesla has not given an updated timeline beyond its previously stated goal of bringing high volume Optimus production online at the site in the summer of 2027. Fremont’s smaller pilot line began mass producing the current Gen 3 robot in January, with that plant expected to build tens of thousands of units this year primarily to generate the real world data Tesla needs to refine the robot’s software before Giga Texas ramps up. Six months of visible construction progress, tracked almost entirely through Tegtmeyer’s recurring drone flights, gives the clearest outside look yet at how seriously Tesla is treating that 2027 deadline.
