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.

The Tesla Model X has always been one of the company’s most loved vehicles, despite its low sales figures, which can be attributed to its high price tag.
However, the Model X has been a signature item on Tesla’s menu of cars, most notably recognized by its Falcon Wing Doors, which are aware of its surroundings and open according to what’s around it.
But recent improvements to the Model X were looking slim to none, but it appears most of the fixes actually happened under the body, at least according to Tesla’s Vice President of Powertrain, Lars Moravy.
In a recent interview with Car and Driver, Moravy detailed all of the changes to the 2026 iteration of the vehicle, which was about 400 pounds lighter than it was originally. The biggest change is a modification with the rear motor, switching from an induction-type motor to a permanent-magnet design and optimizing the half-shafts, which shed about 100 pounds.
Tesla also got “almost 80 pounds out of the interior bits and pieces,” which “included making parts thinner, different manufacturing process choices, and incorporating airbag-deployment requirements into the headliner fabric,” the report said.
Additionally, the standard five-passenger, bench seat configuration saved 50 pounds by ditching pedestal mounting. This also helped with practicality, as it helped the seat fold flat. Engineers at Tesla also saved 44 pounds from the high-voltage wiring through optimizing the wiring from the charge-port DC/DC converter and switching from copper to aluminum wiring.

Tesla also simplified the cooling system by reducing the number of radiators. It also incorporated Nürburgring cooling requirements for the Plaid variant, which saved nearly 30 pounds.
Many Tesla fans will be familiar with the megacastings, manufactured in-house by presses from IDRA, which also saves more than 20 pounds and boosts torsional stiffness by around 10 percent. Tweaks to the suspension also saved 10 pounds.
People were truly disappointed with what Tesla did with the Model S and Model X, arguing that the cars needed a more severe exterior overhaul, which might be true. However, Tesla really did a lot to reduce the weight of the vehicle, which helps increase range and efficiency. According to Grok, every 200 pounds removed adds between 7 and 15 percent to range estimations.
This makes sense considering the range estimations both increased by 7 percent from the Model X’s 2025 configuration to the 2026 builds. Range increased on the All-Wheel-Drive trim from 329 miles to 352 miles, while the Plaid went from 314 miles to 335 miles.
Tesla has officially launched its first branded Supercharger just months after initiating a new program that allows third-party companies to brand their own charging piles.
The site opened in Land O’ Lakes, Florida, and features eight V4 Supercharging stalls offering up to 325 kW of charging speed. It appears it was purchased by a company called Suncoast Credit Union. This particular branch is located Northeast of Tampa, which is on the Gulf of Mexico.
It features graphics of Florida animals, like alligators:

Tesla launched this program back in September, and it basically was a way to expand its Supercharger presence and also allow companies to pay for the infrastructure. Tesla maintains it. When it announced the “Supercharger for Business,” it said:
“Purchase and install Superchargers at your business. Superchargers are compatible with all electric vehicles, bringing EV drivers to your business by offering convenient, reliable charging.”
The program does a few things. Initially, it expands EV charging infrastructure and makes charging solutions more readily available for drivers. It can also attract people to those businesses specifically.

The chargers can also be branded with any logo that the business chooses, which makes them more personalized and also acts as an advertisement.
The best part is that the customers do not have to maintain anything about the Supercharger. Tesla still takes care of it and resolves any issues:
“We treat your site like we treat our sites. By providing you with a full-service package that includes network operations, preventative maintenance, and driver support, we’re able to guarantee 97% uptime–the highest in the industry.”
It appears the Superchargers will also appear within the in-car nav during routing, so they’ll be publicly available to anyone who needs to use them. They are still available to all EVs that have worked with Tesla to utilize its infrastructure, and they are not restricted to people who are only visiting the business.
Tesla has revealed its Cybertruck light bar installation fix after a recall exposed a serious issue with the accessory.
Tesla and the National Highway Traffic Safety Administration (NHTSA) initiated a recall of 6,197 Cybertrucks back in October to resolve an issue with the Cybertruck light bar accessory. It was an issue with the adhesive that was provided by a Romanian company called Hella Romania S.R.L.
Tesla recalls 6,197 Cybertrucks for light bar adhesive issue
The issue was with the primer quality, as the recall report from the NHTSA had stated the light bar had “inadvertently attached to the windshield using the incorrect surface primer.”
Instead of trying to adhere the light bar to the Cybertruck with an adhesive, Tesla is now going to attach it with a bracketing system, which will physically mount it to the vehicle instead of relying on adhesive strips or glue.
Tesla outlines this in its new Service Bulletin, labeled SB-25-90-001, (spotted by Not a Tesla App) where it shows the light bar will be remounted more securely:
The entire process will take a few hours, but it can be completed by the Mobile Service techs, so if you have a Cybertruck that needs a light bar adjustment, it can be done without taking the vehicle to the Service Center for repair.
However, the repair will only happen if there is no delamination or damage present; then Tesla could “retrofit the service-installed optional off-road light bar accessory with a positive mechanical attachment.”
The company said it would repair the light bar at no charge to customers. The light bar issue was one that did not result in any accidents or injuries, according to the NHTSA’s report.
This was the third recall on Cybertruck this year, as one was highlighted in March for exterior trim panels detaching during operation. Another had to do with front parking lights being too bright, which was fixed with an Over-the-Air update last month.
