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.

Just hours after Starship Flight 13 achieved a successful soft splashdown of its upper stage in the Indian Ocean on July 24, Elon Musk announced an ambitious next step for the company’s next launch of the rocket.
“Unless we discover problems after mission data review, SpaceX will attempt to catch the ship with the tower on [the] next flight,” the SpaceX CEO posted on X on Friday.
That “next flight” is expected to be Flight 14. The plan involves returning the Starship upper stage, commonly called the “ship,” to the Starbase launch tower in Texas and catching it mid-air using the same mechanical “chopsticks” arms that have already proven themselves with the Super Heavy booster.

A successful catch would mark the first time an orbital-class upper stage has been recovered this way, advancing SpaceX’s goal of full and rapid reusability for the entire vehicle.
SpaceX has already demonstrated the tower-catch technique multiple times with Super Heavy. The first successful catch came on Flight 5 in October 2024, when Booster 12 was plucked from the sky by the Mechazilla arms. Subsequent flights, including those involving Boosters 14 and 15, repeated the feat. Several of those recovered boosters were later inspected, refurbished, and flown again, proving the system’s viability for quick turnaround.
Traditional reusable rockets, such as SpaceX’s own Falcon 9 or Blue Origin’s New Shepard, land on legs either on land or droneships. Rocket Lab has recovered its small Electron first stages by helicopter, but those are far lighter vehicles.
SpaceX Starship just nailed something it’s never done before
The China Academy of Launch Vehicle Technology (CALT), a subsidiary of the China Aerospace Science and Technology Corp. (CASC), completed a catch of its booster on July 10. They are the only entity besides SpaceX to attempt and complete the feat.
Flight 13 provided encouraging data. The ship executed a controlled reentry, flipped, and soft-landed intact in the ocean after deploying Starlink satellites, offering the first clear post-splashdown views of an undamaged heat shield. The Super Heavy booster, meanwhile, experienced a harder splashdown in the Gulf of Mexico.
Musk has previously stressed that ship catches would only follow multiple successful soft ocean landings to minimize risk of debris over land.
If Flight 14 succeeds, SpaceX would take a major stride toward routine, rapid reuse of both stages—critical for lowering launch costs and supporting ambitious plans for lunar and Mars missions. For now, teams are reviewing the Flight 13 data. Should everything check out, the next Starship flight could deliver one of the most spectacular recoveries in aerospace history.
In a move echoing its earlier commitment to open innovation, Tesla CEO Elon Musk announced recently that the company plans to make the design and software of its Model S and Model X fully open source.
This follows the same approach Tesla took with its original Roadster, releasing all available design, engineering, and diagnostic materials in November 2023 so that “whatever we have, you now have.”
Just as Tesla made the original Roadster design & software open source, we plan to do the same with Model S & X
— Elon Musk (@elonmusk) July 24, 2026
The Model S, introduced in 2012, was Tesla’s first mass-produced vehicle and a groundbreaking luxury electric sedan. It offered impressive range, rapid acceleration, and over-the-air software updates that redefined expectations for electric cars.
The Model X, launched in 2015, built on that foundation as a high-performance electric SUV notable for its distinctive falcon-wing doors, spacious interior, and advanced safety features. Both models served as flagships that helped establish Tesla as a leader in the EV industry and popularized long-range battery-electric vehicles.
Production of the Model S and Model X was wound down earlier in 2026, with manufacturing ending in the second quarter. Tesla redirected the Fremont factory space previously used for these vehicles toward higher-priority projects, including Optimus humanoid robots and the Cybercab autonomous vehicle.
By the time of Musk’s open-source announcement, custom orders had closed and only remaining inventory was available.
Open-sourcing the designs and software offers several clear advantages. Owners of these aging but still capable vehicles gain better access to technical documentation, diagnostic tools, and software resources, making independent repairs and modifications easier and more affordable.
Independent repair shops and third-party specialists can support the large existing fleet without relying solely on Tesla’s service network. Enthusiasts and engineers can study real-world implementations of Tesla’s battery, powertrain, and software systems, potentially accelerating broader industry progress in electric mobility.
The step aligns with Tesla’s 2014 patent pledge and its overall mission to advance sustainable transport by sharing hard-won knowledge rather than locking it behind proprietary walls.
By releasing these materials now that the models have left production, Tesla ensures continued support for its early adopters while freeing internal resources for future technologies. The open-source release of the original Roadster already enabled simulations, community projects, and deeper technical understanding.
Extending that practice to the Model S and Model X should deliver similar benefits on a larger scale, helping keep these influential vehicles relevant and repairable for years to come
Tesla flexed one incredible Robotaxi metric during the Q2 Earnings Call that skeptics have to hate to hear. The company’s platform has already driven more than 380,000 miles of unsupervised ride-hailing across several states with no notable incidents.
During the company’s Q2 Earnings Call on Wednesday, Vice President of AI, Ashok Elluswamy, said:
“First of all, I’d like to state that the Robotaxi program has been operating extremely well. Especially in terms of safety, the program has had an impeccable safety record. We have driven more than 380,000 miles of unsupervised Robotaxi, now across six cities in two different states. We have had zero notable incidents. Any reports have been of other actors impacting us when we were stationary. I like to emphasize how safe the operation has been so far. Zero notable incidents over 380,000 miles.”
Elluswamy’s claim over Robotaxi miles is a significant milestone for Tesla in the grand scheme, especially considering this is a sizeable number of miles without any incident.

Tesla’s self-driving approach is much different than that of other companies. Tesla has maintained that vision is the only thing needed to have a solid and effective self-driving suite. Many self-driving companies utilize things like LiDAR, sensors, and other elements to improve performance, but Elluswamy sent a jab at those who believe it’s needed.
“Historically, the so-called experts have always claimed that you need LiDARs, radars, HD maps, and the entire kitchen sink to drive safely. Here we show that such is not true. You can have safe, comfortable, and affordable autonomy with just cameras. This record should be a huge validation of Tesla’s entire AI approach.”
The feat of accumulating this many miles without any driver behind the wheel is impressive. The thing is, Tesla is also doing this across several different locations, with varying traffic rules, pedestrian levels, weather patterns, and other important factors.
While Tesla is not ready to roll out an unsupervised platform completely, it is a slow but steady indication that the company is well on its way to figuring things out.
The company’s attitude toward expansion is slow, safe, and controlled, and despite this huge milestone, it will still be some time until we see Tesla truly unleash unsupervised rides more aggressively.
