How to activate Tesla Dyno Mode in 3 steps for performance testing
Tesla Dyno Mode can be activated in three easy steps for owners looking to test performance of their all-electric vehicle on a dynamometer and in a controlled setting.
Tesla owner and Drag Times YouTuber Brooks Weisblat posted a video on how to turn on the Dyno Mode on a Model 3 and see how the secret mode affected the car’s performance.
Information on how to enable Model 3 Dyno Mode is also documented on a Tesla EPA filing dated October 2019. The said document details how a user can activate the Dyno Mode in three easy steps.
How to activate Tesla Dyno Mode
- Vehicle must be in Park.
- While holding down left (turn signal) stalk, press and hold the Tesla “T” logo at the top of the screen.
- Enter Dyno Mode activation password, “dynotest”.
Dyno Mode can be deactivated by the user by pressing the “Power Off” button within the Safety & Securit tab of the UI.
Once the Dyno Mode is activated the car will prompt drivers with a warning that the vehicle is on Dyno Mode and that one should not drive on public roads. With the Dyno Mode on the vehicle’s traction control is disabled, stability control is disabled, as well as automatic emergency braking.
“Fair warning — be very, very careful,” said Weisblat.
The Dyno Mode was specifically created to have representative driving controls while testing the vehicle on a chassis dynamometer or a rolling-road dyno where proper vehicle testing and calibration are done.
Weisblat went for a drive to test the performance of the vehicle. Without a Dyno Mode on, his Tesla Model 3 was able to hit 60 mph from a full stop in 3.1 seconds. According to him, his best time historically is 2.9999.
The DragTimes YouTuber turned on Dyno Mode and did another 0-60 mph test and clocked in 3.1 seconds but felt a bit of wheelspin. He gave it a few more tries and was able to clock 3.027 seconds on better pavement. Tesla pegs the 0-60mph time of the Model 3 Performance at 3.2 seconds while its Long Range All-Wheel Drive and Standard Plus versions clock 4.4 seconds and 5.3 seconds, respectively.
Weisblat’s final opinion on the Model 3 Dyno Mode is that it provides a slight improvement but might provide a bit more on a sticky drag track but it’s hard to tell.
“Dyno Mode, it’s pretty much just used for if you’re gonna dyno the car,” he said.
But of course, Model 3 owners who want to drift their Model 3s need to switch off its amazing traction control. Some owners turn off a wheel sensor but the system can go haywire since something is missing. The system will turn off ABS, Autopilot, regenerative braking, and even power steering. Furthermore, taking a wheel sensor out can potentially damage a vehicle.
Again, the Tesla Dyno Mode was created for testing Teslas on a dynamometer. If one will try to drive while it’s on, better stay away from other cars or pedestrians, or better yet, do it on a track.
Here’s the new Tesla Dyno Mode video from Drag Times:

Tesla’s Supercharger Diner in Los Angeles dominated the company’s global usage rankings after just one year, proving the concept is more than just a one-off novelty location that will fade away.
The performance could incite the company to build more locations, something that CEO Elon Musk has hinted at for some time.
Tesla’s Supercharger Diner delivered 21.2 GWh of energy in its first year of operation, the company’s head of Charging, Max de Zegher, revealed on X. Of the top 10 most utilized Supercharger locations in Tesla’s global infrastructure, the Diner in Los Angeles was the most used by drivers, and it wasn’t particularly close:
Tesla Diner opened exactly 1 year ago. Inspiring that futuristic places like this exist.
It’s our highest usage Supercharger in the world: 21.2 GWh delivered in a year, 1.6k sessions/day.

On its launch day one year ago, nobody was too sure what the Tesla Diner would be about. It seemed like an interesting concept, and considering it had been in the works for years, it was a highly anticipated launch that many were looking forward to.
Based on its success, we could see additional Diners with Superchargers built throughout the United States, and potentially beyond. Musk has said on several occasions that the company would be willing to bring the Diner idea to more markets.
Tesla makes major change at Supercharger Diner amid epic demand
Of the markets that Musk has mentioned, both Palo Alto and Austin have come to be perceived as ideal selections. However, there are no concrete plans as of now to build new Supercharger Diners anywhere; the location on Santa Monica Boulevard will remain the exclusive spot to pick up Tesla-inspired eats, at least for the time being.
Tesla short sellers won big following the company’s massive fall on Wall Street after it reported subpar Earnings on Wednesday.
Tesla short sellers collected about $4.12 billion in single-day profits on Thursday, according to Bloomberg. Shares fell as much as 15 percent during Thursday’s session. It closed as one of the worst days for Tesla on Wall Street in the past three years.
Investors sold off the stock after Tesla said it would aggressively direct its spending toward AI and its Optimus robot project. The company had record revenues, which were driven by one of the strongest quarters in terms of vehicle deliveries in company history.
However, it missed EPS estimates by reporting just $0.33, a far cry from the $0.53 analysts expected.
S3 Partners reported that about 3 percent of Tesla’s outstanding stock is sold short. Managing Director at S3, Ihor Dusaniwsky, provided the short seller’s potential profit, as well as another figure: shorts have likely had paper gains of $8.92 billion this year, as Tesla shares are down 30 percent in 2026.
Tesla (TSLA) Q2 2026 earnings results: miss on EPS, beat on revenue
Tesla has burned short sellers many times in the past, but the company’s latest Earnings Call was a chance for those skeptics to taste some payback. Although the company gave some very transparent information regarding future projects, the rollout of Robotaxi, Optimus, and Semi, many investors took their profits on Thursday.
Notable short sellers like Michael Burry have been transparent about their skepticism around Tesla shares. Burry just revealed three weeks ago that he had opened up a new short on the stock, stating he shorted Tesla shares at $416.22. “Happy it jumped back to this level,” he said in a blog post.
At the time of publication, Tesla shares were down about 3 percent and the stock was trading at $309.92.
Tesla’s long-standing saga regarding its door handles and a manual release has entered its latest chapter, and as a result, a big change is coming.
On Friday, the National Highway Traffic Safety Administration (NHTSA) denied Tesla’s petition that was seeking a defect investigation into roughly 180,000 Model 3 vehicles for an issue involving the emergency mechanical door release.

NHTSA said that Tesla’s petition did not present evidence of a safety-related defect in the door handles or their emergency releases. Instead, the agency determined that it would rather solve the issue of the lack of labeling or location of emergency mechanical door releases and the federal safety rules that govern them.
Essentially, the NHTSA wants to create and enforce rules that would require automakers to make emergency door latch releases more clearly labeled in a car. Despite a Tesla having manual door releases on all four passenger doors, many people do not know they exist or how they work.
Tesla addresses door handle complaints with simple engineering fix
In recent times, Tesla has faced some criticism involving its door handles, specifically because some occupants have reported that they are unable to exit their vehicles after losing power. The door handles on a Tesla are electronically operated, but in the event that the 12V battery dies, there is a manual release that can be used.
The NHTSA only identified a single complaint involving the mechanical door releases: a 2022 Model 3 owner said the release was concealed and unlabeled after the vehicle lost power after a front-end collision. It has also already started to create a separate rulemaking process to make emergency door-egress systems more obvious.
It should be noted that all Teslas have mechanical emergency door releases, but they are placed in various locations as the vehicles have aged and been redesigned from year to year. Refer to the safety manual for your vehicle if you have any confusion about where the emergency releases are and how they work.
