Tesla Model S Plaid ‘Cyber Cart’ attempts new quarter mile record
The quest to break the fastest quarter-mile time for the Tesla Model S Plaid continues for YouTubers BoostedBoiz, as they returned to the track for more attempts at the record.
Last time the Model S Plaid was at the track, the car had been completely stripped and all body panels removed. Removing the vast majority of the car resulted in a weigh-in at 3.850 lbs. The “Cyber Kart,” as the YouTubers dubbed it, proceeded to make it down the track with a time of 8.83 seconds at 149 miles per hour, still well short of the record.
In their latest attempt at the record, they decided to add the front fenders, bumpers, and hood for better aerodynamic performance as the car accelerates down the track. Almost like the design of the Model S was optimized for aerodynamics for a reason.
At the track, the YouTubers also taped up the panel gaps and changed to lighter wheels and track tires from Blake Fuller, who holds many lap records in his race-modified Model S Plaid, including lap records at Sebring, Mount Washington, Homestead, and a few other raceways.
The first run down the track with better tires resulted in a time of 8.91 seconds at 151 miles per hour, and in an effort to run a faster time, they added a layer of thick plastic wrap over the roof, the passenger side door, and partially on the driver side.
The increased aerodynamics resulted in a run of 8.86 seconds at 152 miles per hour, while still slower than their run of 8.83 seconds days before, they picked up a higher mile per hour and were running on a less prepared track surface. It’ll be interesting to see if they can break the record in their next attempt at the track and if they add more to help with aerodynamics.
In another video released by the channel, they took the Model S Plaid to a spectator drag race at an oval track and took on a twin-turbo Porsche 911 Turbo S. While the Model S Plaid didn’t beat the Porsche around the track, it did keep up the car and at one point almost slid into the retaining wall at the track but was saved the by the driver.
Do you think this project will be able to break the record with a few more modifications, or has it peaked in its performance?

Production-ready Tesla Cybercab hits showroom floor in San Jose
Tesla has implemented subtle but significant updates to both the Cybercab’s exterior and interior elements.
Tesla has showcased what appears to be a near-production-ready Cybercab at its Santana Row showroom in San Jose, California, giving visitors the closest look yet at the autonomous two-seater’s refined design.
Based on photos of the near-production-ready vehicle, the electric vehicle maker has implemented subtle but significant updates to both the Cybercab’s exterior and interior elements, making the vehicle look more polished and seemingly more comfortable than its prototypes from last year.
Exterior and interior refinements
The updated Cybercab, whose photos were initially shared by Tesla advocate Nic Cruz Patane, now features a new frameless window design, an extended bottom splitter on the front bumper, and a slightly updated rear hatch. It also includes a production-spec front lightbar with integrated headlights, new wheel covers, and a license plate bracket.
Notably, the vehicle now has two windshield wipers instead of the prototype’s single unit, along with powered door struts, seemingly for smoother opening of its butterfly doors. Inside, the Cybercab now sports what appears to be a redesigned dash and door panels, updated carpet material, and slightly refined seat cushions with new center cupholders. Its legroom seems to have gotten slightly larger as well.
Cybercab sightings
Sightings of the updated Cybercab have been abundant in recent months. At the end of October, the Tesla AI team teased some of the autonomous two-seater’s updates after it showed a photo of the vehicle being driven through an In-N-Out drive-through by employees in Halloween costumes. The photos of the Cybercab were fun, but they were significant, with longtime Tesla watchers noting that the company has a tradition of driving its prototypes through the fast food chain’s drive-throughs.
Even at the time, Tesla enthusiasts noticed that the Cybercab had received some design changes, such as segmented DRLs and headlamps, actual turn signals, and a splitter that’s a lot sharper. Larger door openings, which now seem to have been teasing the vehicle’s updated cabin, were also observed at the time.
Investor's Corner
Tesla analyst realizes one big thing about the stock: deliveries are losing importance
Tesla analyst Dan Levy of Barclays realized one big thing about the stock moving into 2026: vehicle deliveries are losing importance.
As a new era of Tesla seems to be on the horizon, the concern about vehicle deliveries and annual growth seems to be fading, at least according to many investors.
Even CEO Elon Musk has implied at times that the automotive side, as a whole, will only make up a small percentage of Tesla’s total valuation, as Optimus and AI begin to shine with importance.
He said in April:
“The future of the company is fundamentally based on large-scale autonomous cars and large-scale and large volume, vast numbers of autonomous humanoid robots.”
Almost all of Tesla’s value long-term will be from AI & robots, both vehicle & humanoid
— Elon Musk (@elonmusk) September 11, 2023
Levy wrote in a note to investors that Tesla’s Q4 delivery figures “likely won’t matter for the stock.” Barclays said in the note that it expects deliveries to be “soft” for the quarter.
In years past, Tesla analysts, investors, and fans were focused on automotive growth.
Cars were truly the biggest thing the stock had to offer: Tesla was a growing automotive company with a lot of prowess in AI and software, but deliveries held the most impact, along with vehicle pricing. These types of things had huge impacts on the stock years ago.
In fact, several large swings occurred because of Tesla either beating or missing delivery estimates:
- January 3, 2022: +13.53%, record deliveries at the time
- January 3, 2023: -12.24%, missed deliveries
- July 2, 2024: +10.20%, beat delivery expectations
- October 3, 2022: -8.61%, sharp miss due to Shanghai factory shutdown
- July 2, 2020: +7.95%, topped low COVID-era expectations with sizeable beat on deliveries
It has become more apparent over the past few quarters that delivery estimates have significantly less focus from investors, who are instead looking for progress in AI, Optimus, Cybercab, and other projects.
These things are the future of the company, and although Tesla will always sell cars, the stock is more impacted by the software the vehicle is running, and not necessarily the vehicle itself.

Tesla removes Safety Monitors, begins fully autonomous Robotaxi testing
This development, in terms of the Robotaxi program, is massive. Tesla has been working incredibly hard to expand its fleet of Robotaxi vehicles to accommodate the considerable demand it has experienced for the platform.
Tesla has started Robotaxi testing in Austin, Texas, without any vehicle occupants, the company’s CEO Elon Musk confirmed on Sunday. Two Tesla Model Y Robotaxi units were spotted in Austin traveling on public roads with nobody in the car.
The testing phase begins just a week after Musk confirmed that Tesla would be removing Safety Monitors from its vehicles “within the next three weeks.” Tesla has been working to initiate driverless rides by the end of the year since the Robotaxi fleet was launched back in June.
Two units were spotted, with the first being seen from the side and clearly showing no human beings inside the cabin of the Model Y Robotaxi:

Another unit, which is the same color but was confirmed as a different vehicle, was spotted just a few moments later:
NEWS: A second Tesla Model Y Robotaxi running FSD Unsupervised has just been spotted driving itself on public roads in Austin, Texas, with no one in the front seats.
This is a different car from the one spotted earlier. They have different license plates.

The two units are traveling in the general vicinity of the South Congress and Dawson neighborhoods of downtown Austin. These are located on the southside of the city.
This development, in terms of the Robotaxi program, is massive. Tesla has been working incredibly hard to expand its fleet of Robotaxi vehicles to accommodate the considerable demand it has experienced for the platform.
However, the main focus of the Robotaxi program since its launch in the Summer was to remove Safety Monitors and initiate completely driverless rides. This effort is close to becoming a reality, and the efforts of the company are coming to fruition.
Testing is underway with no occupants in the car

It is a drastic step in the company’s trek for self-driving technology, as it plans to expand it to passenger vehicles in the coming years. Tesla owners have plenty of experience with the Full Self-Driving suite, which is not fully autonomous, but is consistently ranked among the best-performing platforms in the world.
