Tesla is designing an electric pump system that makes its drive units even better
Amidst Tesla’s continued efforts to usher in an era of mobility optimized for the convenience and safety of car owners, the electric car maker is exploring new ways to improve its vehicles’ systems. Recently published patent applications, for one, indicate that Tesla is working on better damage monitoring features, as well as safer seats that are capable of classifying a car’s occupants. Apart from these, Tesla is also looking into improving its vehicles’ electric pump system, which could ultimately result in better cooling and diagnostics.
The patent application, published on January 3, 2019 and titled “Electric Pump System and Method,” explores improvements that could be implemented on traditional pump systems used in automobiles. As noted by Tesla, traditional oil pumps, particularly those that are used for EV components such as the drive unit, do not have the capability to monitor oil condition. As a result, oil that is used to lubricate an electric car’s drive unit need to be changed on a regular basis (albeit very infrequently).
In the discussion section of its patent application, Tesla pointed out that traditional oil pumps are unable to accurately determine temperature, since temperature sensors are usually located outside of a conventional pump system. Apart from this, the electric car maker notes that conventional oil pumps are also large and unwieldy due to attachment mechanisms comprised of different parts. With these points for improvement in mind, Tesla has pointed out that there is a need for an “improved oil pump — in particular an electric pump system — designed to work in conjunction with an electric motor.”

Tesla’s patent describes an electric pump system that “presents methods and structures that help overcome the difficulties of operating a cooling and lubrication system, in particular, managing the transfer of heat and assessment of fluid temperature in electric pump systems.” The Silicon Valley-based carmaker describes its electric pump system design as follows.
“There is provided an apparatus that includes an electronic control unit, a mechanical pump, and a motor having a first side and a second side, the motor including: a stator, a rotor including a hollow shaft, and a housing around the stator and rotor, wherein the electronic control unit is connected to the first side of the motor, wherein the mechanical pump is connected to the second side of the motor, wherein the hollow shaft defines a shaft inlet and a shaft outlet, wherein the mechanical pump defines a first fluid passageway from a first pump inlet to the shaft inlet, wherein the housing defines an internal motor cavity, wherein the shaft outlet is in fluid communication with the internal motor cavity, wherein the mechanical pump defines a second fluid passageway from a second pump inlet to a pump outlet, and wherein the motor housing and mechanical pump define a third fluid passageway from the internal motor cavity to the pump outlet via a third pump inlet.”
“In some embodiments the apparatus according to the above-described aspect of the present disclosure or any other aspects thereof, a number of optional operations and features may be employed. One optional feature is the electronic control unit further including a thermistor to measure a temperature of a fluid exiting the shaft outlet. Another optional feature is wherein the housing defines a bypass inlet in fluid communication with the internal motor cavity. Another optional feature is at least a portion of the second fluid passageway and the third fluid passageway is common. Another optional feature is the mechanical pump is a gerotor. Another optional feature is the electronic control unit includes a microcontroller controlling the mechanical pump. Another optional feature is the electronic control unit includes cooling ribs.”

With such a design, the fluid temperature inside the electric pump system could be used to control and optimize the lubrication system of a vehicle, thereby improving the efficiency of an electric drive unit. Depending on the temperature of the oil in the system, the electric pump could react accordingly, even warning the vehicle’s computers that something is wrong. The readings from the electric pump system can be used to monitor the health of a vehicle’s drive unit as well. Tesla explains this process in the following discussion.
“The fluid temperature may be controlled to achieve certain lubrication properties. For example, hotter oil has lower viscosity which reduces drag and hydraulic power to pump the fluid, which can increase efficiency. If the oil becomes too hot, however, it will not provide sufficient cooling. The fluid temperature reading feature of the oil pump can monitor the general health and performance of the fluid in the electric drive unit system. For example, if the oil is too hot, the oil pump may alert the car computer that something is wrong, for oil that is too hot can damage or/and reduce the life of some components on the drive unit.”
“Stated another way, the temperature of fluid may be used to monitor the health and performance of the drive unit. The ECU may capture other information besides the temperature, such as pump speed, pump current composition, oil pressure, or other information. The information captured by the ECU may then be fed into a proprietary algorithm that monitors oil pump and overall drive unit health. The algorithm may provide an indication of service, such as when oil must be replaced or when the drive train needs to be serviced.”
What is particularly notable is that these improvements could result in enhancements to Tesla’s drive units, which are already among the best in the industry. The Model 3’s drive unit, for one, has been lauded by veteran teardown experts such as Sandy Munro as industry-leading. In a recent appearance at Autoline TV, for one, Munro noted that Tesla’s drive units are practically a class above its competitors.
Tesla’s constant efforts to improve its vehicles are highlighted by the patent applications from the company that have been published over the past months. Among these include an automatic tire inflation system that hints at off-road capabilities for the company’s vehicles, a system that allows Tesla to address panel gaps during vehicle assembly, a way to produce colored solar roof tiles, and even a model that utilizes electric cars as a way to improve vehicle positioning, to name a few.

SpaceX just forced Verizon, AT&T and T-Mobile to team up for the first time in history
AT&T, T-Mobile, and Verizon just joined forces for one reason: Starlink is winning.
America’s three largest wireless carriers, AT&T, T-Mobile, and Verizon, announced on On May 14, 2026 that they had agreed in principle to form a joint venture aimed at pooling their spectrum resources to expand satellite-based direct-to-device (D2D) connectivity across the United States in what can be seen as a direct response to SpaceX’s Starlink initiative. D2D, in plain terms, is technology that lets a standard smartphone connect directly to a satellite in orbit, the same way it connects to a cell tower, with no extra hardware required.
The alliance is widely seen as a means to slow Starlink’s rapid expansion in the satellite internet and mobile markets. SpaceX’s Starlink Mobile service launched commercially in July 2025 through a partnership with T-Mobile, starting with messaging before expanding to broadband data. SpaceX secured access to valuable wireless spectrum through its $17 billion deal with EchoStar, paving the way for significantly faster satellite-to-phone speeds.
SpaceX was not shy about its reaction. SpaceX president and COO Gwynne Shotwell responded on X: “Weeeelllll, I guess Starlink Mobile is doing something right! It’s David and Goliath (X3) all over again — I’m bettin’ on David.” SpaceX’s VP of Satellite Policy David Goldman went further, flagging potential antitrust concerns and asking whether the DOJ would even allow three dominant competitors to coordinate in a market where a new rival is actively entering.

Financial analysts at LightShed Partners were blunt, saying the announcement showed the three carriers are “nervous,” and pointed to the timing: “You announce an agreement in principle when the point is the announcement, not the deal. The timing, weeks ahead of the SpaceX roadshow, was the point.”
As Teslarati reported, SpaceX’s next generation Starlink V2 satellites will deliver up to 100 times the data density of the current system, with custom silicon and phased array antennas enabling around 20 times the throughput of the first generation. The carriers’ JV, which has no definitive agreement, no financial structure, and no deployment timeline yet, will need to move quickly to matter.
Elon Musk’s SpaceX is targeting a Nasdaq listing as early as June 12, aiming for what would be the largest IPO in history. With Starlink now serving over 9 million subscribers across 155 countries, holding 59 carrier partnerships globally, and now powering Air Force One, the carriers’ joint venture announcement landed at exactly the wrong time to look like anything other than a defensive move.
Tesla just raised Model Y prices for the first time in two years, with the largest increase being $1,000.
The move signals shifting dynamics in the competitive electric vehicle market as the company continues to work on balancing demand, profitability, and accessibility.
The new pricing affects premium trims while leaving entry-level options unchanged. The Model Y Premium Rear-Wheel Drive (RWD) now starts at $45,990, a $1,000 increase.
The Model Y Premium All-Wheel Drive (AWD)—previously referred to in the post as simply “Model Y AWD”—rises to $49,990, also up $1,000. The top-tier Model Y Performance sees a more modest $500 bump, bringing its starting price to $57,990.
Tesla Model Y prices just went up:
New prices:
🚗 Model Y Premium RWD: $45,990 – up $1,000

Base models remain untouched to preserve affordability. The entry-level Model Y RWD holds steady at $39,990, and the base Model Y AWD stays at $41,990. This selective approach keeps the crossover accessible for budget-conscious buyers while extracting more revenue from higher-margin configurations.
After years of aggressive price cuts to stimulate volume amid slowing EV adoption and rising competition from rivals like BYD, Ford, and GM, Tesla appears confident in underlying demand. Recent lineup refreshes for the 2026 Model Y, including refreshed styling and efficiency gains, have helped maintain its status as America’s best-selling EV.
By protecting base prices, Tesla avoids alienating price-sensitive customers while improving margins on the more popular variants.
Tesla Model Y ownership review after six months: What I love and what I don’t
For consumers, the changes are relatively modest—under 3% on affected trims—and still position the Model Y competitively against gas-powered SUVs in the same class. Federal tax credits and potential state incentives may further offset costs for eligible buyers.
This marks a subtle but notable shift from the deep discounting era that defined much of 2024 and 2025. As the EV market matures into 2026, Tesla’s pricing strategy will be closely watched for clues about production ramps, new variants like the rumored longer-wheelbase Model Y, and broader profitability goals.
In short, today’s adjustment reflects a company that remains dominant yet pragmatic—willing to test higher pricing where demand supports it. It is unlikely to deter consumers from choosing other options.
Elon Musk cannot be fired from SpaceX, and there’s a reason for that.
In a blunt post on X on Friday, Elon Musk confirmed plans to structurally shield his leadership at SpaceX, ensuring he cannot be fired while tying a potential trillion-dollar compensation package to the company’s long-term goal of establishing a self-sustaining colony on Mars.
Yes, I need to make sure SpaceX stays focused on making life multiplanetary and extending consciousness to the stars, not pandering to someone’s bullshit quarterly earnings bonus!
Obviously, IF SpaceX succeeds in this absurdly difficult goal, it will be worth many orders of…
— Elon Musk (@elonmusk) May 15, 2026
The revelation stems from a Financial Times report detailing SpaceX’s intention to restructure its governance and compensation framework. The moves are designed to protect Musk’s control and align his incentives with the company’s founding mission rather than short-term financial pressures. Musk’s reply left no ambiguity:
“Yes, I need to make sure SpaceX stays focused on making life multiplanetary and extending consciousness to the stars, not pandering to someone’s bullshit quarterly earnings bonus!”
He added that success in this “absurdly difficult goal” would generate value “many orders of magnitude more than the economy of Earth,” though he cautioned that the journey will not be smooth. “Don’t expect entirely smooth sailing along the way,” Musk wrote.
The strategy reflects Musk’s deep concerns about how public-market expectations could derail SpaceX’s core objective. Founded in 2002, SpaceX has repeatedly stated its purpose is to reduce the cost of space travel and ultimately make humanity a multiplanetary species.
Unlike Tesla, which went public in 2010 and has faced repeated battles over Musk’s compensation and board influence, SpaceX remains privately held. Musk has long resisted taking the rocket company public precisely to avoid the quarterly earnings treadmill that forces most CEOs to prioritize short-term stock performance over ambitious, high-risk projects.
By embedding protections against his removal and linking any outsized pay package to verifiable milestones—such as a functioning Mars colony—SpaceX aims to insulate its leadership from activist investors or board members who might demand faster profits or safer bets.
Musk has referenced past experiences, including his ouster from OpenAI and shareholder lawsuits at Tesla, as cautionary tales. In those cases, he argued, external pressures risked diluting the original vision.
Critics may view the arrangement as excessive, especially given Musk’s already substantial voting power and wealth. Supporters, however, argue it is a necessary safeguard for a company pursuing goals measured in decades rather than quarters. Achieving a Mars colony would require sustained investment in Starship development, orbital refueling, life-support systems, and in-situ resource utilization—technologies that may deliver no immediate financial return.
Musk’s post underscores a broader philosophical point: true breakthrough innovation often demands tolerance for volatility and a willingness to ignore conventional business wisdom. As SpaceX prepares for increasingly ambitious Starship test flights and eventual crewed missions, the new governance structure signals that the company’s North Star remains unchanged—humanity’s expansion beyond Earth.
Whether the trillion-dollar package materializes depends on execution, but Musk’s message is clear: SpaceX exists to reach the stars, not to chase the next earnings beat. For investors or employees who share that vision, the protections are not a perk—they are a prerequisite for success.
