Tesla’s electric cars are already among the most efficient vehicles on the market, and this is shown by the immense gap between the range and efficiency of the company’s vehicles compared to their competitors from veteran automakers. Part of the reason behind this is Tesla’s continued improvements in its vehicles, which are rolled out and adopted as soon as they are refined and ready. 

One of these improvements appears to have been teased in a recently-published patent application. Simply titled “Steering System for a Vehicle,” the document describes a smart, novel way of designing a power steering system that is more compact and less power-hungry. In the patent’s background, Tesla remarked that conventional power steering systems, which are usually hydraulically operated, are mostly bulky and space-consuming.

This is due to power steering systems utilizing a number of components that include cylinders, pumps, hoses, and control valves, to name a few. Hydraulic power steering systems also have complex designs, which add cost to a vehicle. Lastly, conventional power steering systems generally require a large amount of power to function. With this in mind, Tesla argues that there is a need for a new power steering system that is simpler, smaller, and more power-efficient.

Tesla’s novel power steering design involves fewer parts than the conventional system used in most vehicles. The electric car maker describes the design in its patent in the description below. 

“The steering system includes a drive motor having a motor shaft. The steering system also includes a first gear reduction stage for receiving a first rotational input from the motor shaft and providing a first rotational output. A first gear meshes with a second gear of the first gear reduction stage via a helical gear mesh. The steering system further includes a second gear reduction stage for receiving the first rotational output from the first gear reduction stage and providing a second rotational output.

“The second gear reduction stage may include at least one of a strain wave gearing, a worm drive, and a planetary gearing. In case the second reduction stage is a strain wave gearing, the second gear reduction stage includes an ovular coupler, a flexible coupling, an outer spline, and a plurality of bearing members disposed between the ovular coupler and the flexible coupling. The steering system includes an output shaft for receiving the second rotational output from the second gear reduction stage.”

Tesla notes that its smaller, power-saving steering system, apart from being more power-efficient and compact, also includes several failsafes, which could, in turn, increase a vehicle’s safety. The company’s patent mentions “sacrificial or failsafe components,” which are designed to safeguard a vehicle’s sensitive components during the event of a breakdown. Such a design will likely contribute to Tesla’s electric cars and their already-stellar safety ratings.

“In some embodiments, steering system 102 has been shown to provide a 10% improvement over a hydrolytic steering system. Additionally, steering system 102 is a compact unit that consumes lesser space as compared to other steering systems that are commercially available in markets. Further, steering system 102 does not require large amount of additional power for operation. FIG. 6 illustrates a failure mode of steering system 102 in which one or more bearing members 244 of steering system 102 fail. Bearing members 244 of steering system 102 are designed to withstand high loads so that they do not fail during normal vehicle operation. However, bearing members 244 may be designed to withstand only a predetermined threshold of load. As a result, bearing members 244 fail when they are loaded beyond the predetermined threshold. 

“For example, a bearing member 258 may eventually fail along a shear plane 260 when loaded beyond the predetermined threshold. Alternatively, bearing members 244 may undergo a bending failure, or any other type of failure. In such a situation, one bearing member 244 is a sacrificial or failsafe components, thereby safeguarding other components of vehicle, for example, drive motor 204 or an engine, against breakdown or seizing. More particularly, the one bearing members 244 fails, ovular coupler 238 locks and rotates with flexible coupling 240. Thus, steering system 102 can still be operated to allow vehicle to be driven for a certain distance and parked at an appropriate location. Bearing member 244 fails according to a sheer mechanism or another failure mechanism. Further, failed bearing member 258 can be replaced and vehicle can be reinstated without incurring any additional losses.”

It remains to be seen if Tesla’s compact power steering system will be adopted for the company’s upcoming vehicles. That being said, such a system is a perfect match for EVs such as the Tesla Semi, the Tesla Pickup Truck, and the Model S and X Plaid Powertrain variants. These are all large vehicles, and their success in the market will likely be determined in no small part by their range and efficiency. In this light, every single innovation that could optimize these vehicles’ efficiency will most definitely be appreciated. After all, the less power is consumed by subsystems such as a vehicle’s power steering unit, the more power there is to turn an electric car’s wheels.

Tesla Earnings: financial expectations and what we should to hear about

In terms of discussions, Tesla earnings calls are usually a great time to get some clarification on the company’s outlook for its current and future projects.

Tesla (NASDAQ: TSLA) will report its earnings for the first quarter of 2026 this evening after the market closes, and analysts have already put out their expectations from a financial standpoint for the company’s first three months of the year.

Additionally, there will be plenty of things that will be discussed, including the recent expansion of the Robotaxi program, the Roadster unveiling, and Full Self-Driving (Supervised) approvals across the globe.

Financial Expectations

Wall Street consensus expectations put Tesla’s Earnings Per Share (EPS) at $0.36, while revenues are expected to come in around $22.35 billion.

This would compare to an EPS of $0.27 and $19.34 billion compared to Tesla’s Q1 2025. Last quarter, EPS came in at $0.50 on $29.4 billion of revenue.

Tesla beat analyst expectations last quarter, but the next trading day, the stock fell nearly 3.5 percent. We never quite can gauge how the market will respond to Tesla’s earnings; we’ve seen shares rise on a miss and fall on a beat.

It really goes on the news, and investor consensus, it seems.

What to Expect

In terms of discussions, Tesla earnings calls are usually a great time to get some clarification on the company’s outlook for its current and future projects. Right now, the big focus of investors is the Robotaxi program, the Roadster unveiling, and what the outlook for Full Self-Driving’s expansion throughout Europe and the rest of the world looks like.

Robotaxi

Tesla just recently expanded its unsupervised Robotaxi program to Dallas and Houston, joining Austin as the first cities in the U.S. to have access to the company’s ride-hailing suite.

Some saw this move as a quick effort to turn attention away from a delivery miss and an anticipated miss on earnings. However, we’ve seen Tesla be more than deliberate with its expansion of the Robotaxi suite, so it’s hard to believe the company would make this move if it were not truly ready to do so.

The company is also working to expand its U.S. ride-hailing service outside of Texas and California, and recently filed paperwork to build a Robotaxi-exclusive Supercharger stall.

Expansion is planned for Florida, Nevada, and Arizona at some point this year, with more states to follow.

Roadster Unveiling

The Roadster unveiling was slated for April 1, and then pushed back (once again) to “probably late April,” according to Elon Musk.

It does not appear that the Roadster unveiling will happen within that time frame, at least not to our knowledge. Nobody has received media or press invites for a Roadster unveiling, and given the lofty expectations set for the vehicle by Musk and Co., it seems like something they’d want to show off to the public.

Tesla Roadster unveiling set for this month: what to expect

The Roadster has become a truly frustrating project for Tesla and its fans; evidently, there is something that is not up to the expectations Musk and others have. Meanwhile, fans are essentially waiting for something that is six years late.

At this point, also given the company’s focus on autonomy, it almost seems more worth it to just cancel it, remove any and all timelines and expectations, and surprise people with something crazy down the line, maybe in two or three years. There should be no talk of it.

Full Self-Driving Global Expansion

We expect Musk and Co. to shed some details on where it stands with other European government bodies, as it recently was able to roll out FSD (Supervised) to customers in the Netherlands.

Spain is also working with Tesla to assess FSD’s viability as a publicly available option for owners.

With that being said, there should be some additional information for investors as they listen to the call; no talk of it would be a pretty big letdown.

Optimus

There will likely be a date set for the Gen 3 Optimus unveiling, and we’re hopeful Tesla can keep that date set in stone and meet it. Not reaching timelines is a relatively minor issue, but a company can only do this for so long before its fans and investors start to lose trust and disregard any talk about dates.

It seems this is happening already.

Optimus has been pegged as Tesla’s big money maker for the future. The goals and expectations are high, but it is a privilege to have that sort of pressure when investors know the company’s capability.

Tesla just unlocked sales to 50,000+ government agencies

It marks a significant step in expanding Tesla’s presence in the public sector, where procurement processes have traditionally slowed electric vehicle adoption.

Tesla just unlocked sales to over 50,000 government agencies by entering a new agreement with Sourcewell, a purchasing cooperative.

Tesla entered a new master purchasing agreement with Sourcewell, the largest government purchasing cooperative in the U.S. This will enable streamlined sales of its EVs to more than 50,000 U.S. public entities. Tesla entered Designated Contract 0813525-TES, and the agreement covers Model 3, Model Y, and Cybertruck, and potentially other vehicles the company could release.

It marks a significant step in expanding Tesla’s presence in the public sector, where procurement processes have traditionally slowed electric vehicle adoption.

The deal allows eligible agencies, including cities, school districts, state governments, and higher-education institutions, to purchase Tesla vehicles directly through Sourcewell without conducting their own lengthy competitive bidding or request-for-proposal (RFP) processes.

Pricing is pre-negotiated and capped, providing transparency and predictability. Agencies simply register for a Sourcewell account online or by phone and place orders under the existing contract. This cooperative model aggregates demand across thousands of members, reducing administrative costs and time while ensuring compliance with public procurement rules.

For Tesla, the agreement removes major barriers to government fleet sales. Public-sector procurement cycles often stretch 12 to 18 months due to bidding requirements and committee reviews.

By securing the master contract, Tesla gains immediate, simplified access to a massive customer base that previously faced friction in adopting EVs. The company highlighted in its announcement that the partnership will help these 50,000-plus agencies “save thousands of $$$ in operating costs for their vehicle fleet over time” through lower maintenance, energy efficiency, and the elimination of tailpipe emissions.

The initial four-year term runs through November 13, 2029, with options for up to three one-year extensions, offering long-term stability for both parties.

Sourcewell’s role is central to execution. As a cooperative purchasing organization, it negotiates and manages vendor contracts on behalf of its members, then makes them available nationwide. Participating entities contact Tesla’s dedicated fleet team or Sourcewell representatives to complete purchases, bypassing redundant paperwork.

This structure accelerates fleet electrification while maintaining fiscal accountability—agencies receive pre-vetted pricing and terms without reinventing the wheel for each vehicle order.

The partnership positions Tesla to capture a larger share of the public fleet market, where total cost of ownership often favors electric vehicles once procurement hurdles are removed.

For government buyers, it translates to faster deployment of sustainable fleets, reduced long-term expenses, and alignment with environmental mandates. As more agencies transition, the contract could contribute to broader EV infrastructure growth and taxpayer savings across the country.

How much of SpaceX will Elon Musk own after IPO will surprise you

SpaceX’s IPO filing confirms Musk will maintain his voting power to make key decisions for the company.

Elon Musk will retain dominant voting control of SpaceX after it goes public, according to the company’s IPO prospectus that was filed with the SEC. The filing reveals a dual-class equity structure giving Class B shareholders 10 votes each, concentrating power with Musk and a handful of other insiders, while Class A shares sold to public investors carry one vote.

Musk holds approximately 42% of SpaceX’s equity and controls roughly 79% of its votes through super-voting shares. He will simultaneously serve as CEO, CTO, and chairman of the nine-member board after the listing. Beyond that, the filing includes provisions that may limit shareholders’ influence over board elections and legal actions, forcing disputes into arbitration and restricting where they can be brought.

The case for Musk holding this level of control is grounded in SpaceX’s actual history. The company’s most important bets, from reusable rockets to a global satellite internet constellation, were decisions that ran against conventional aerospace thinking and would likely have faced resistance from a board accountable to investor gains. Fully reusable rockets were considered economically irrational by established industry players for years. Starlink, which now generates over $4 billion in annual operating profit, was widely dismissed as financially unviable when it was proposed. The argument for concentrated founder control seems straightforward, and the decisions that built SpaceX into what it is today required someone willing to ignore consensus and absorb years of losses.

For context, Musk’s position is significantly more dominant than Zuckerberg’s at Meta. The comparison with Tesla is also worth noting. When Tesla did its IPO in 2010, it did not issue dual-class shares. Musk has only recently pushed for enhanced voting protection, proposing at least 25% control at Tesla in 2024 after selling shares to fund his Twitter acquisition left him with around 13%.

SpaceX has clearly learned from that experience and structured the IPO differently by planning to allocate up to 30% of shares to retail investors, roughly three times the typical norm for a large offering. The roadshow is expected to begin the week of June 8, with a Nasdaq listing rumored to be a $1.75 trillion valuation and a $75 billion raise.
