Tesla Roadster performance specs are actual and not theoretical, says test driver
Emile Bouret, the man behind the wheel of the next-gen Roadster during the vehicle’s test drives last November, recently called on all car enthusiasts to support the upcoming all-electric supercar. According to the veteran test driver, vehicles like the next-generation Roadster have the potential to make the automotive world a “better place,” considering that it would likely trigger a race to make cars that are even more impressive.
Bouret has worked with Tesla since the company’s early days. A close friend of Tesla chief designer Franz von Holzhausen and a 28-year veteran of the auto industry, Bouret has been asked to test drive the electric car makers’ vehicles from the original Tesla Roadster and the Model S. During his interview with YouTube’s VINwiki channel, Bouret admitted that he does not really understand the hate being directed towards the next-gen Tesla Roadster.
“I love that I live in a world where all these cars exist. You have Koenigseggs and Paganis and Ferraris and Lamborghinis and McLarens and Porsches and Rimacs and Teslas. So, I know there’s a lot of hate out there, but I just don’t understand it. If you’re a car person, wouldn’t you root for everybody? I’m definitely rooting for them because the world will be a better place if that car does get built and it gets on the road, because other people are gonna build cars to beat it — and we’re gonna win.”
The next-generation Tesla Roadster gave the auto industry a massive surprise when Elon Musk unveiled the vehicle last November. The all-electric supercar’s claimed specs, after all, including its 0-60 mph time of 1.9 seconds, it’s quarter-mile time of 8.8 seconds, and its range of 620 miles per charge, have caused some controversy among conventional car enthusiasts. Among the most prominent points of skepticism include speed limitations because of the vehicle’s tires, as well as battery technology that is yet to be attained.
Tesla, however, has assured that the specs announced for the next-gen Roadster are actually conservative. According to Bouret, the upcoming all-electric supercar’s figures related by Elon Musk were not theoretical. They were the actual numbers that their tests have shown.
“Those aren’t theoretical. Those aren’t calculations. We’ve done those numbers. And I probably shouldn’t say that those numbers are even conservative, but they are. That thing is going to be a proper weapon,” he said.
The pervading doubts cast on the next-generation Tesla Roadster’s speed and range are understandable, considering that no other vehicle on the road today boasts comparable specs and performance. Over the past few months, however, Tesla has been dropping hints that the company does have all the necessary resources it needs to attain, or even surpass, the vehicle’s specs that were announced last November.

Just last month, for example, Elon Musk openly discussed the idea of using some of SpaceX’s technology to augment the performance capabilities of the next-generation Tesla Roadster. According to Musk, the upcoming supercar would use Composite Overwrapped Pressure Vessels (COPV), which are used by SpaceX’s Falcon rockets during re-entry and landing, to help the car’s acceleration and maneuverability. As we noted in a previous report, the seemingly outlandish idea is actually feasible.
As for the next-gen Roadster’s battery technology, Tesla CTO JB Straubel discussed it best during the company’s Q1 2018 earnings call. While addressing a question about the Tesla Semi’s range, Straubel noted that much of the doubts behind the company’s estimated range for its vehicles comes from a misunderstanding of the company’s battery tech.
“I think the key point is that it doesn’t require a dramatic breakthrough. So there’s a fundamental misunderstanding, I think, of what the current technology in our existing products can actually do. If they’re benchmarking sort of the best battery pack they can buy from a supplier, and then mapping that with what the Semi could do, it doesn’t solve. I think that’s maybe where most of it is coming from, but we basically have what we need in-house, and understand how to do those specs today,” Straubel said.
The next-generation Tesla Roadster is expected to enter production sometime in 2020. Test drives for the vehicle are expected to begin late next year.

Tesla Cybercab spotted with interesting charging solution, stimulating discussion
The port is located in the rear of the vehicle and features a manual door and latch for plug-in, and the video shows an employee connecting to a Tesla Supercharger.
Tesla Cybercab units are being tested publicly on roads throughout various areas of the United States, and a recent sighting of the vehicle’s charging port has certainly stimulated some discussions throughout the community.
The Cybercab is geared toward being a fully-autonomous vehicle, void of a steering wheel or pedals, only operating with the use of the Full Self-Driving suite. Everything from the driving itself to the charging to the cleaning is intended to be operated autonomously.
But a recent sighting of the vehicle has incited some speculation as to whether the vehicle might have some manual features, which would make sense, but let’s take a look:
🚨 Tesla Cybercab charging port is in the rear of the vehicle!
Here’s a great look at plugging it in!!

The port is located in the rear of the vehicle and features a manual door and latch for plug-in, and the video shows an employee connecting to a Tesla Supercharger.
Now, it is important to remember these are prototype vehicles, and not the final product. Additionally, Tesla has said it plans to introduce wireless induction charging in the future, but it is not currently available, so these units need to have some ability to charge.
However, there are some arguments for a charging system like this, especially as the operation of the Cybercab begins after production starts, which is scheduled for April.
Wireless for Operation, Wired for Downtime
It seems ideal to use induction charging when the Cybercab is in operation. As it is for most Tesla owners taking roadtrips, Supercharging stops are only a few minutes long for the most part.
The Cybercab would benefit from more frequent Supercharging stops in between rides while it is operating a ride-sharing program.

However, when the vehicle rolls back to its hub for cleaning and maintenance, standard charging, where it is plugged into a charger of some kind, seems more ideal.
In the 45-minutes that the car is being cleaned and is having maintenance, it could be fully charged and ready for another full shift of rides, grabbing a few miles of range with induction charging when it’s out and about.
Induction Charging Challenges
Induction charging is still something that presents many challenges for companies that use it for anything, including things as trivial as charging cell phones.
While it is convenient, a lot of the charge is lost during heat transfer, which is something that is common with wireless charging solutions. Even in Teslas, the wireless charging mat present in its vehicles has been a common complaint among owners, so much so that the company recently included a feature to turn them off.
Production Timing and Potential Challenges
With Tesla planning to begin Cybercab production in April, the real challenge with the induction charging is whether the company can develop an effective wireless apparatus in that short time frame.
It has been in development for several years, but solving the issue with heat and energy loss is something that is not an easy task.
In the short-term, Tesla could utilize this port for normal Supercharging operation on the Cybercab. Eventually, it could be phased out as induction charging proves to be a more effective and convenient option.

Tesla confirms that it finally solved its 4680 battery’s dry cathode process
The suggests the company has finally resolved one of the most challenging aspects of its next-generation battery cells.
Tesla has confirmed that it is now producing both the anode and cathode of its 4680 battery cells using a dry-electrode process, marking a key breakthrough in a technology the company has been working to industrialize for years.
The update, disclosed in Tesla’s Q4 and FY 2025 update letter, suggests the company has finally resolved one of the most challenging aspects of its next-generation battery cells.
Dry cathode 4680 cells
In its Q4 and FY 2025 update letter, Tesla stated that it is now producing 4680 cells whose anode and cathode were produced during the dry electrode process. The confirmation addresses long-standing questions around whether Tesla could bring its dry cathode process into sustained production.
The disclosure was highlighted on X by Bonne Eggleston, Tesla’s Vice President of 4680 batteries, who wrote that “both electrodes use our dry process.”
Tesla first introduced the dry-electrode concept during its Battery Day presentation in 2020, pitching it as a way to simplify production, reduce factory footprint, lower costs, and improve energy density. While Tesla has been producing 4680 cells for some time, the company had previously relied on more conventional approaches for parts of the process, leading to questions about whether a full dry-electrode process could even be achieved.
4680 packs for Model Y
Tesla also revealed in its Q4 and FY 2025 Update Letter that it has begun producing battery packs for certain Model Y vehicles using its in-house 4680 cells. As per Tesla:
“We have begun to produce battery packs for certain Model Ys with our 4680 cells, unlocking an additional vector of supply to help navigate increasingly complex supply chain challenges caused by trade barriers and tariff risks.”
The timing is notable. With Tesla preparing to wind down Model S and Model X production, the Model Y and Model 3 are expected to account for an even larger share of the company’s vehicle output. Ensuring that the Model Y can be equipped with domestically produced 4680 battery packs gives Tesla greater flexibility to maintain production volumes in the United States, even as global battery supply chains face increasing complexity.

Tesla Giga Texas to feature massive Optimus V4 production line
This suggests that while the first Optimus line will be set up in the Fremont Factory, the real ramp of Optimus’ production will happen in Giga Texas.
Tesla will build Optimus 4 in Giga Texas, and its production line will be massive. This was, at least, as per recent comments by CEO Elon Musk on social media platform X.
Optimus 4 production
In response to a post on X which expressed surprise that Optimus will be produced in California, Musk stated that “Optimus 4 will be built in Texas at much higher volume.” This suggests that while the first Optimus line will be set up in the Fremont Factory, and while the line itself will be capable of producing 1 million humanoid robots per year, the real ramp of Optimus’ production will happen in Giga Texas.
This was not the first time that Elon Musk shared his plans for Optimus’ production at Gigafactory Texas. During the 2025 Annual Shareholder Meeting, he stated that Giga Texas’ Optimus line will produce 10 million units of the humanoid robot per year. He did not, however, state at the time that Giga Texas would produce Optimus V4.
“So we’re going to launch on the fastest production ramp of any product of any large complex manufactured product ever, starting with building a one-million-unit production line in Fremont. And that’s Line one. And then a ten million unit per year production line here,” Musk stated.
How big Optimus could become
During Tesla’s Q4 and FY 2025 earnings call, Musk offered additional context on the potential of Optimus. While he stated that the ramp of Optimus’ production will be deliberate at first, the humanoid robot itself will have the potential to change the world.
“Optimus really will be a general-purpose robot that can learn by observing human behavior. You can demonstrate a task or verbally describe a task or show it a task. Even show it a video, it will be able to do that task. It’s going to be a very capable robot. I think long-term Optimus will have a very significant impact on the US GDP.
“It will actually move the needle on US GDP significantly. In conclusion, there are still many who doubt our ambitions for creating amazing abundance. We are confident it can be done, and we are making the right moves technologically to ensure that it does. Tesla, Inc. has never been a company to shy away from solving the hardest problems,” Musk stated.
