Tesla owner converts Model S 75D to P100DL on the cheap with Rich Rebuilds
Tesla owner and automotive enthusiast Rich Rebuilds is known for his crazy vehicle modifications and salvage electric car initiatives. For his most recent project, Rich opted to upgrade a Model S 75D to a P100DL for an owner who wanted a Tesla with more range, power, and speed without buying a whole new car altogether.
The Model S 75D in question belonged to a close friend who was interested in getting a vehicle with better specs and performance. At first, the owner attempted to trade-in his Model S 75D for a P100DL. However, Tesla’s trade-in offer was not up to the owner’s expectations, so he came to Rich for help with the upgrade.
The owner then obtained a P100DL that was involved in an accident for $30,000. Despite the vehicle being totaled, its electric motor and battery were usable. The upgrade process required Rich and the team at the Electrified Garage to remove the 75D’s rear drivetrain and battery, which packs 329 horsepower and an EPA-estimated 259 miles of range.
The first step of the project required the removal of the 75D’s drive unit. The swap was a straightforward step that required the removal of a few nuts and bolts, along with the disconnection of the drivetrain’s coolant tubes and power cables. Then, the removal of the 75 kWh battery pack was next, another relatively easy step.
The removal of the battery pack is not usually necessary for drivetrain replacements. However, for the Model S 75D to be upgraded adequately to a P100DL, the two vehicles’ battery packs needed a swap. The differences between the motors required a replacement of power cables from the motor to the front junction box as well, which sits near the front of the vehicle. According to the Tesla Model S Owners Manual, “The front junction box provides power to various components, such as the Battery heater, the air conditioning compressor and the cabin heater.”
The team ran into a small issue when replacing the rear junction box. The cables from the 75D’s junction box lock into the part, so the Electrified Garage team chose to swap out this junction box with a component from the P100D. Additionally, the Model S 75D’s drivetrain harness was too small to handle the P100D’s motor, so the team had to utilize the performance version’s harness, which required a complete swap out as well.
The cooling systems between the two vehicles were also slightly different and required attention. The 75D’s cooling system only utilized one line and is cooled by oil with a heat exchanger installed. The P100DL’s drive unit, on the other hand, has two coolant lines which connect directly to the motor itself. This step required a small modification from the Electrified Garage team so the vehicle would operate correctly.
After completing the project, the owner took the 75D’s motor and battery, along with the rest of the P100D, and sold them. The project set the owner back only $33,000 in total, including $9,000 in labor costs from the Electrified Garage.
The upgrade in drivetrain and battery pack for the Model S 75D gave ultimately resulted in a Model S P100DL for a vastly reduced price. In the case of Rich’s recent project, the owner was able to obtain more range, speed, and horsepower without spending about $100,000 for a new Model S P100DL.

Tesla launched the all-electric, steering wheel-less, and pedal-less Cybercab last night at a quiet and small event in downtown Austin, Texas.
The launch, which marked the beginning of unsupervised ride-hailing for Tesla’s Robotaxi platform with Cybercab, has already caught the attention of the National Highway Traffic Safety Administration (NHTSA) who has more questions.
NHTSA opened an Audit Query (AQ) into the Cybercab’s Federal Motor Vehicle Safety Standards (FMVSS) certification that Tesla gave the vehicle. Manufacturers self-certify vehicles much of the time to avoid excessive regulatory delays.

However, the agency needs more information; it said in a summary:
“On September 3, 2026, Tesla began commercial deployment with a small number of its Cybercab vehicles in Austin, Texas. Tesla notified the Agency that it certified those Cybercab vehicles as compliant with all applicable Federal Motor Vehicle Safety Standards (FMVSS). Tesla also notified the Agency that it plans to gradually expand commercial deployment of the Cybercab to include additional vehicles and locations.”
It also went on to state that the Cybercab lacks traditional automotive controls, which is a groundbreaking move. The process is entirely new to the NHTSA, which gives the agency some leverage to put Tesla’s launch under a microscope:
“The vehicles lack permanently attached, conventional manual controls, such as a brake pedal, gas pedal, steering wheel, and mirrors. NHTSA is opening this AQ to examine the process and technical data on which Tesla relied when certifying the Cybercab and related issues. Among other things, NHTSA will consider the extent to which Tesla’s certification depended on determinations that certain FMVSS are inapplicable to the Cybercab.”
Tesla has added 45 Cybercab units to its fleet of Robotaxi-enabled cars in Austin, according to public documents the company submitted to the State of Texas over the past week. Enabling this level of self-driving is something Tesla has worked toward for many years, and now that it is finally here, it seems more than reasonable that regulatory agencies will have some questions.
Many outlets might try to frame this as a negative, but it is truly an agency looking to gain more information about groundbreaking tech that Tesla has been developing for years.
In an effort to keep riders, pedestrians, and property safe, any and all data accumulated from these first days, weeks, and months of rides will likely be shared with the NHTSA to enable broader rollout strategies across the United States and more in the future.

Tesla Cybercab is coming to Asia this month as US service officially begins
Tesla Asia says Cybercab will be on display in Hong Kong, Tokyo, Beijing and Shanghai this month.
Tesla’s Cybercab is heading to Asia. The official Tesla Asia account posted on X Thursday, inviting Cybercab fans to “Come experience the future of autonomy in Hong Kong, Tokyo, Beijing & Shanghai.” The post went up within hours of Tesla’s own Cybercab milestone in Texas, where the company said Thursday it had begun offering rides in across Austin.
Exact dates and venues for the Asia tour haven’t been released yet, though Tesla Hong Kong replied to the announcement with “Cybercab will be on display in Hong Kong soon,” while Tesla Japan’s response pointed fans to a sign up page for updates. Neither post mentions test rides or a service area, and nothing so far suggests Tesla is launching Robotaxi operations in any of the four cities. Based on how Tesla has run past Cybercab tours, in Europe in late 2024 and at US shopping centers that same December, the Asia stops are almost certainly static displays at Tesla stores or public venues as a means to stimulate buzz for its future driverless ride-hailing service in the big cities.

The timing lines up with Tesla’s only prior Cybercab appearance in the region, a booth at the China International Import Expo in Shanghai last November, which Teslarati covered at the time. At that event, Tesla’s regional general manager for Shanghai framed the car as evidence of the company’s broader mission, a message Tesla has since formalized in its Master Plan Part IV, which states that “autonomous vehicles have the capacity to dramatically improve the affordability, availability and safety of transportation while reducing pollution, particularly in our increasingly dense global cities.” The same document is where Tesla lays out its “sustainable abundance” framing for Cybercab and Optimus alike, describing the two as the hardware behind an AI driven push to cut the cost of transportation and labor at scale.
Whether Cybercab actually operates as a robotaxi anywhere in Asia remains an open question, considering China has already pushed an autonomous ride-hailing market that’s run on homegrown players like Baidu’s Apollo Go and Pony AI. For now, the four city tour reads as a marketing push timed to Austin’s momentum.

Tesla Cybertruck targets job site crews with new Tailgate Utility Track and Bed Gear Box accessory
Tesla launched a $350 tailgate track and a $985 lockable Bed Gear Box for Cybertruck.
Tesla’s Cybertruck team added two more items to the Tesla Shop, targeting job site crews and owners who use the truck bed for actual work rather than just showing it off. The official Cybertruck X account posted the Tailgate Utility Track and the Bed Gear Box within minutes of each other, part of a five item batch that also included a reflective jacket, a spray paint hat and an updated reflective tee.
The Tailgate Utility Track runs $350 and turns the folded down tailgate into another mounting surface. It’s a single aluminum track with a T-slot for sliding accessories and two L-track attachment points, plus two load stops included in the box. The pitch is straightforward: strap down oversized cargo, like lumber or a cooler, that hangs off the back of the bed without it sliding out mid-drive. It bolts onto the existing tailgate and works on every Cybertruck trim.

The Bed Gear Box costs $985 and is a different kind of accessory. It’s a lockable aluminum storage box, 55.78 inches long, 19.8 inches wide and 7.79 inches tall, that mounts to the bed’s L-track rails and comes with two internal bins for smaller items. According to Tesla, at just over 57 pounds empty, it’s meant to stay in place rather than come in and out with each trip, giving owners a factory-fit alternative to loose totes for tools, recovery gear or emergency supplies. Tesla’s listing notes that Long Range and Dual Motor AWD Cybertrucks need the L-Tracks accessory installed separately before the Gear Box will mount, since L-tracks come standard only on certain configurations.

Both accessories lean on the idea Tesla has been building toward since Elon Musk first described the Cybertruck’s third-party attachment strategy at the 2023 shareholder meeting, when he said the truck would ship with mounting points so outside companies, and Tesla itself, could keep adding gear without redesigning the bed. That’s the same L-track backbone underneath the tailgate shield and jumpseats Tesla launched last year, and the off-road armor package that arrived through the same X account in 2025.
Owners looking to round out the rest of the L-track ecosystem, cargo dividers, MOLLE panels, bed racks and similar gear, can find a wider range of options through our Cybertruck accessories collection.
