Tesla Model S hailed as fastest-selling 2nd hand electric car in the US
The Tesla Model S has been dubbed as the fastest-selling all-electric car in the United States’ second-hand car market from January to July this year. The full-sized premium sedan was given the distinction by automotive research firm iSeeCars.com, which aggregates second-hand auto listings across the country.
For its recent study, the auto research firm analyzed more than 4 million 1-3-year-old cars that were sold from January to July 2018. The firm noted in a report that overall, late-model vehicles usually take an average of 46.4 days before they are sold. iSeeCars.com CEO Phong Ly pointed out that cars which take longer to sell on the second-hand market usually signify that supply exceeds demand, while vehicles that are sold quickly usually connote that supply is lower than demand.
“It’s important to know how long vehicles stay on dealer lots because slower-moving cars can present negotiation opportunities for consumers. Cars that remain on market for longer than average indicate that supply is higher than demand, which could mean the pricing is too high or that the car isn’t as well-liked as its competitors,” Ly noted.
Among the United States’ available all-electric vehicles, the Tesla Model S stands as the fastest-selling used car from January to July. The all-electric car, which is designed by the company to be a vehicle that exceeds fossil fuel-powered competitors, spent an average of 32.4 days on used car dealer lots before getting sold. The iSeeCars.com CEO notes that such findings are primarily due to the Model S’ dominance in the premium all-electric car segment.
“The Model S is currently the only all-electric luxury car available, and its demand outstrips supply leading to scarcity in the used-car marketplace. Those who purchase a new model have to wait at least a month for delivery while there is no wait time for a used version,” Ly noted.
The Tesla Model S ranked as the second-fastest-selling used passenger car in the United States overall as well, directly behind the Toyota Prius C, an affordable hybrid vehicle that’s smaller than the full-sized Toyota Prius. The Prius C takes an average of 29.6 days before it is sold on second-hand dealer lots.
The findings of iSeeCars.com‘s study are in line with the results of another survey conducted by car-shopping platform Autolist.com last year. The results of Autolist.com‘s study concluded that used Tesla Model S sell 5% quicker than other luxury sedans from competing automakers such as the Audi A7, the Porsche Panamera, the BMW 6 Series, the Mercedes-Benz CLS, and even the Lexus LS 460. This was despite the average listing price of second-hand Model S being roughly 3% to 5% higher than comparable vehicles.
The number of the company’s electric cars on US roads is bound to increase, particularly since Tesla is now optimizing the production of the Model 3. With this, the second-hand market for the company’s electric cars would likely exhibit some growth. The impending rise in the number of Teslas on the road has been teased by Elon Musk in a letter to employees, where he noted that the company is “about to have the most amazing quarter in (its) history, building and delivering more than twice as many cars as (it) did last quarter.”
Considering that Tesla delivered a total of 40,740 vehicles and produced a total of 53,339 electric cars in Q2 2018, Elon Musk’s statement in his letter appears to be quite ambitious. That being said, Tesla board member Kimbal Musk noted during a recent segment on CNBC’s Closing Bell that this month would be pretty exciting for the company.
“This month is an exciting month for us. You know, it’s really gonna blow people’s minds how many Model 3s are gonna appear in America in just the next couple of weeks,” he said.

Tesla (NASDAQ: TSLA) is set to hold its Earnings Call for the first quarter of 2026 on Wednesday, and there are a lot of interesting things that are swirling around in terms of speculation from investors.
With the company’s executives, including CEO Elon Musk, answering a handful of questions that investors submit through the Say platform, fans want to know a lot of things about a lot of things.
These five questions come from Retail Investors, who are normal, everyday shareholders:
- When will we have the Optimus v3 reveal? When will Optimus production start, since we ended the Model S and Model X production earlier than mid-year? What’s the expected Optimus production rate exiting this year? What are the initial targeted skills?
- What milestones are you targeting for unsupervised FSD and Robotaxi expansion beyond Austin this year, and how will that drive recurring revenue?
- How will Hardware 3 cars reach Unsupervised Full Self-Driving?
- When do you expect Unsupervised Full Self-Driving to reach customer cars?
- When will Robotaxi expand past its current limited rollout?
Additionally, these are currently the three questions that are slated to be answered by Institutional Firms, which also answer a handful of questions during the call:
- Now that FSD has been approved in the Netherlands and is expected to launch across Europe this summer, can you discuss your Robotaxi strategy for the region?
- What enabled you to finish the AI5 tapeout early and were there any changes to the original vision? Last week, Elon said AI5 will go into Optimus and the Supercomputer, but one month ago said it would go into the Robotaxi. Has AI5 been dropped from the vehicle roadmap?
- Given the recent NHTSA incident filings, can you update us on the Robotaxi safety data? If safety validation remains the primary bottleneck, why not deploy thousands of vehicles to accelerate the removal of the safety driver?
The questions range through every current Tesla project, including FSD expansion and Optimus. However, many of the answers we will get will likely be repetitive answers we’ve heard in the past.
This is especially pertinent when the questions about when Unsupervised FSD will reach customer cars: we know Musk will say that it will happen this year. Is Tesla capable of that? Maybe. But a more transparent answer that is more revealing of a true timeline would be appreciated.
Hardware 3 owners are anxiously awaiting the arrival of FSD v14 Lite, which was promised to them last year for a release sometime this year.
The Earnings Call is set to take place on Wednesday at market close.

Elon Musk reveals shocking Tesla Optimus patent detail
What looked promising on paper and in simulations failed to deliver the reliability required for a robot expected to handle delicate tasks like folding laundry, assembling electronics, or assisting in factories and homes.
Elon Musk revealed a shocking detail on the Tesla Optimus patent that was revealed last week. Despite it being made public for the first time, Musk said the company has already moved on from the design, an incredible truth about the development of new technology: things move fast.
Musk dropped a bombshell about the Tesla Optimus humanoid robot hand patent that was released last week. Musk, candidly replying to a post late at night on X, revealed that what is a new technology to many fans and insiders is actually old news to those developing the tech directly.
“We already changed the design,” Musk said. “This one didn’t actually work.”
We already changed the design. This one didn’t actually work.

Patents, after all, are often viewed as blueprints for future products. Yet Musk revealed that the rolling contact mechanism—intended to provide smooth, low-friction articulation in the fingers—had already been scrapped after real-world testing exposed its shortcomings.
What looked promising on paper and in simulations failed to deliver the reliability required for a robot expected to handle delicate tasks like folding laundry, assembling electronics, or assisting in factories and homes.
The hand has been one of the biggest challenges for Tesla engineers since Optimus development started years ago. Musk has said that there is not enough recognition for how incredible and useful the human hand is, and designing one for a humanoid robot has been the biggest challenge of all.
Tesla is stumped on how to engineer this Optimus part, but they’re close
This moment underscores the persistent engineering hurdles in achieving reliable humanoid hand dexterity. Human fingers are marvels of evolution: 27 bones, intricate tendons, ligaments, and a network of sensors working in perfect harmony. Replicating that in metal and silicon is extraordinarily difficult.
Rolling contacts promised reduced wear and precise motion, but testing likely revealed issues with durability under repeated stress, grip stability on varied surfaces, or the micro-precision needed for fine motor skills.
These aren’t minor tweaks, but instead they represent fundamental challenges that have plagued robotics teams for decades. Even advanced competitors struggle here—hands remain the Achilles’ heel of most humanoids because the margin for error is razor-thin.
A fraction of a millimeter off, and a robot drops a glass or fails to button a shirt.
What makes Musk’s reply remarkable is how it signals Tesla’s direct communication style on prototype limitations. While many companies guard failures behind glossy marketing and vague timelines, Tesla openly shares setbacks.
Musk was forthcoming about the failure of this recent design. This transparency builds trust with investors, engineers, and fans. It shows Tesla treats Optimus development like true science: rapid iteration, rigorous testing, and zero tolerance for hype that doesn’t match reality.
The disclosure from Musk also highlights Tesla’s blistering pace of development. By the time the patents are published, which is often over a year after the initial filing, the technology has already evolved.
Optimus is far from a static product, and it’s a living project advancing weekly.
In the high-stakes race for general-purpose robots, Tesla’s approach stands out. Admitting a finger-joint design “didn’t actually work” isn’t a weakness—it’s confidence.
True innovation demands confronting failure head-on, and Musk just reminded the world that Optimus is being engineered that way. The next version of those hands is already in testing, and it will be better because Tesla isn’t afraid to say what didn’t work.

Tesla is sending its humanoid Optimus robot to the Boston Marathon
Tesla’s Optimus robot is heading to the Boston Marathon finish line
Tesla’s Optimus humanoid robot will be stationed at the Tesla showroom at 888 Boylston Street in Boston, right along the final stretch of the Boston Marathon today, ready to cheer on runners and pose for photos with spectators.
According to a Tesla email shared by content creator Sawyer Merritt on X, Optimus will be at the Boston Boylston Street showroom on April 20, coinciding with Marathon Monday weekend. The Boston Marathon finishes on Boylston Street, and the surrounding area draws hundreds of thousands of spectators along with international broadcast coverage. Placing Optimus there puts it in front of a massive public audience at zero advertising cost.
Just got this email. @Tesla’s Optimus robot is coming to Boston.

The Tesla showroom is at 888 Boylston Street, between Gloucester Street and Fairfield Street. The final mile of the marathon runs directly along Boylston Street, with runners passing the big stores before reaching the finish line at Copley Square.
Optimus was first announced at Tesla’s AI Day event on August 19, 2021, when Elon Musk presented a vision for a general-purpose robot designed to take on dangerous, repetitive, and unwanted tasks. In March 2026, Optimus appeared at the Appliance and Electronics World Expo in Shanghai, where on-site staff stated that mass production of the robot could begin by the end of 2026. Before that, it showed up at the Tesla Hollywood Diner opening in July 2025 and at a Miami showroom event in December 2025.
Tesla’s well-calculated display of Optimus gives the public a low-pressure first encounter with a robot that Tesla is preparing to soon deploy at scale. The company has previously indicated plans to manufacture Optimus robots at its Fremont facility at up to 1 million units annually, with an Optimus production line at Gigafactory Texas targeting 10 million units per year.

Musk has said that Optimus “has the potential to be more significant than the vehicle business over time,” and separately that roughly 80 percent of Tesla’s future value will come from the robot program. Whether that holds depends on production execution. For now, Boston gets a preview of what that future looks like, standing at the finish line on Boylston Street while 32,000 runners pass by.
