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 says it has launched ride-hailing Robotaxi teaser to employees only

Tesla is using Full Self-Driving (Supervised) to court employees around in two areas.

Tesla announced earlier today that it has already launched an abbreviated version of what will eventually be launched as its Robotaxi fleet in both Austin and the San Francisco Bay Area. It is available to employees, Tesla said.

The automaker did not specify exactly how long it has been operating the fleet, which uses the company’s Full Self-Driving (Supervised) suite, but it did indicate that it has completed over 1,500 trips, totaling 15,000 miles of driving.

As seen in the video shared by the company, there is a human driver still responsible for keeping tabs on the car and its movements. It is not the version that Tesla plans to eventually roll out in June, which would be completely unsupervised.

Tesla said that using this service has helped develop and validate Full Self-Driving networks. It will also be used to create a mobile app that will facilitate ride requests, vehicle allocation, mission control, and remote assistance operations.

The app appears to be somewhat similar to the images Tesla shared of a mock-up version of the platform last year.

Right around this time in 2024, Tesla shared images of what would be the ride-hailing app for the company, enabling passengers to request a ride from a driverless robotaxi:

We also know, according to Tesla App Updates on X, that Tesla will simply integrate this ride-hailing portion of the platform directly into the app the company already operates. There will be no dedicated app for requesting a ride:

The company said in 2024 when teasing the app:

“We have been investing in the hardware and software ecosystems necessary to achieve vehicle autonomy and a ride-hailing service. We believe a scalable and profitable autonomy business can be realized through a vision-only architecture with end-to-end neural networks, trained on billions of miles of real-world data.”

Tesla said it still remains on track to launch a pilot version of the Robotaxi program in Austin in June, something the company has reiterated several times since the start of the new year.

Tesla analyst sees brighter future after Elon Musk reduces DOGE work

Wedbush hikes TSLA’s price target after Musk says he’s cutting back on DOGE. Analyst Dan Ives calls it a “turning point” for Tesla’s story.

Wedbush Securities analyst Daniel Ives sees a brighter future for the automaker now that Elon Musk plans to reduce his time with the DOGE team. After the company’s latest earnings call, the long-time TSLA bull raised Tesla’s price target from $315 to $350 with a BUY rating.

“Last night was a pivotal conference call for Musk to turn the corner from this dark chapter as 1Q numbers [ending] a disaster quarter in which deliveries were very soft and Tesla missed the Street on basically every metric.

“More important than numbers, this was the time [Elon] Musk could pivot, speak to shareholders/employees, and take a turn away from the DOGE/Trump White House and recommit as CEO of Tesla…and he did it loudly and clearly in a conference call that we view as a turning point in the Tesla story,” Ives said after Tesla’s earnings call.

Before Tesla’s Q1 2025 earnings call, the Wedbush analyst said the company was at a crossroads. He listed six factors that might be affecting Tesla, which he believed the company should address. Number one on Ives’ list was Tesla’s ascension to a global political symbol associated with the Trump Administration and DOGE.

It must be noted that these are Ives’ opinions and do not apply to the entire public. Some groups separate Elon Musk and Tesla from President Trump and his administration.

During the recent TSLA earnings call, Elon Musk made the separation more apparent partly by announcing that he would significantly reduce his time with DOGE.

“And I think starting probably next month, May, my time allocation to Doge will drop significantly…But starting next month, I’ll be allocating far more of my time to Tesla and now that the major work of establishing the Department of Government Efficiency is done,” Musk said.

Musk also shared his stance on Trump’s auto tariffs, differentiating himself further from the U.S. President and the current administration.

“And I undoubtedly, I’m gonna get a lot of questions about tariffs. And I just wanna emphasize that the tariff decision is entirely up to the President of the United States. I will weigh in with my advice with the President, which he will listen to my advice. But then it’s up to him, of course, to make his decision.

“I’ve been on the record many times saying that I believe lower tariffs are generally a good idea for prosperity, but this decision is fundamentally up to the elected representative of the people being the President of the United States. So, you know, I’ll continue to advocate for lower tariffs rather than higher tariffs, but that’s all I can do,” Musk said.

In its Q1 2025 Update letter, Tesla shared that all Model Y and Model 3 units delivered in America use 100% U.S.-built battery packs. The announcement reveals Tesla’s forward-thinking strategies and showcases how prepared it is to take on President Trump’s auto tariffs.

“Gigafactory Nevada achieved record battery pack production. Model 3 and Model Y deliveries in the U.S. are now made with 100% U.S.-built battery packs,” noted Tesla in its recent update letter.

During the TSLA Q1 2025 earnings call, Tesla’s Supply Chain Executive, Karn Budhiraj, noted that the company is regionalizing its batteries to mitigate supply chain risks.

“Building on our efforts to reduce supply risk, we have developed our 4680 supply to ensure each component is sourced from at least two countries of origin.” added Tesla in its letter.

Karn clarified that Tesla adopted its regionalization strategy before the pandemic and accelerated efforts after the pandemic. Tesla’s strategy to mitigate supply chain risks includes supply diversification, dual sourcing, vertical integration, advanced analytics, and local partnerships.

Elon Musk commented that Tesla might be the most vertically integrated car company since Henry Ford’s time. He pointed out that Tesla already has a lithium refinery in South Texas and a cathode refinery in Austin. He added that Tesla could have an anode refinery or figure out how to eliminate that part of the cell.

“That’s the dream, [for] lithium batteries to not have an anode. But either way, we better have the anode, the cathode, the lithium, and the electrolytes, and the separator to make a cell. But, there’s no other car company that is building lithium refineries and cathode refineries. Were ridiculously vertically integrated. And that’s our best position to protect against supply chain disruptions,” Musk said.

In its update letter, Tesla noted that its lithium refining and cathode production plants are on track to start production this year. The two Tesla refineries will on-shore production of critical battery materials in the United States, an essential task considering Trump’s auto tariffs.
