The Tesla Cybertruck’s many features are now appearing as patents that the automaker has submitted to the United States Patent Office, and one of the most notable is the tonneau, or truck bed cover. While the retractable design of the tonneau provides convenience at the touch of a button for owners, it will protect any goods or cargo that drivers will store in the Cybertruck’s massive bed. However, the design is now hinting toward even more versatility and usefulness as the patent describes the potential use as a solar panel that will provide range for the all-electric truck by capturing the sun’s energy.
In Tesla’s newly published “Integrated Tonneau Cover for a Vehicle” patent, several inventors submit their idea and designs for the Cybertruck’s fully mechanical tonneau cover. Guided along a set of channels in the bed of the truck, the tonneau cover will provide protection for any cargo that is stored in the back of the vehicle. Whether it be tools or luggage, the tonneau cover is Tesla’s way of giving owners a way to protect their belongings without having to purchase expensive aftermarket bed covers, which other trucks do not provide. The retractable tonneau is shown in the images below.

“In order to mitigate the possibility of such damage, many truck owners install aftermarket truck bed covers that cover the bed of their truck,” the patent states. “However, not only may such aftermarket truck bed covers be difficult to install, they also may not fit exactly with the specifications of the truck beds of different models of trucks. If a truck bed cover does not have an accurate fit it can leak rain or snow through the gaps between the truck bed cover and the walls around the truck bed, and cause cargo damage. In addition, not only are many aftermarket truck bed covers difficult to install and inconvenient to use, but they also take up space in the truck beds and reduce the overall utility of the trucks.”
The tonneau, in a revolutionary new design, will also be able to recharge the vehicle’s battery pack thanks to 110 solar electric cells that are electrically connected to a photovoltaic charging system and battery. “When the tonneau cover is deployed to cover the bed and the solar electric cells that make up the slats are facing the sun, the battery within the electric vehicle can be charged by solar electric cells,” the patent states.
While solar panels on an electric vehicle have been looked at as a possibility in the past, the idea has never come to fruition due to ineffectiveness. Because a car doesn’t provide much surface area, to begin with, the contribution of charge from solar panels would be minimal, and it would require extremely clear and favorable weather conditions to provide any effective additional range to the vehicle. However, CEO Elon Musk hinted just days after the Cybertruck’s unveiling event in November 2019 that Tesla would be adding an option to add solar power that could generate up to 15 miles per day. Musk also hinted toward “fold-out solar wings” that could generate an additional 30-40 miles per day, which could alleviate the need to stop at a Supercharger for some owners.
Will be an option to add solar power that generates 15 miles per day, possibly more. Would love this to be self-powered. Adding fold out solar wings would generate 30 to 40 miles per day. Avg miles per day in US is 30.

The tonneau would be completely covered in solar electric cells, and the patent claims that when the “truck bed cover is in a closed position, it is configured to recharge the battery pack, the closed position of the truck bed cover enabling the plurality of solar electric cells to face a sun.”
Musk also hinted toward the possibility of installing solar cells on the roof of a potential Tesla van with Joe Rogan in a podcast interview earlier this year. Musk said that the van would be a favorable design due to its “big, flat area,” and “solar could start to make a little more sense.” Because the tonneau is flat and covers a considerable surface area, there is some potential for it to be just as effective as Musk’s idea for the van.

Tesla just gave what is perhaps its biggest signal yet that the launch of the Cybercab, its autonomous ride-hailing-geared car, is imminent.
The Cybercab has been spotted outside of Gigafactory Texas in massive numbers over the past few days, with hundreds of units being stored on property just days after the vehicle received a Certificate of Conformity from the EPA.
Today, things were a bit different.
Cybercabs spotted on Giga Texas property today had an addition: a Cybercab decal on the side, reminiscent of the “Robotaxi” ones that were placed on Model Ys just as the company launched its ride-sharing platform about a year ago.
Giga Texas drone operator Joe Tegtmeyer noticed the change today:

Tesla could be signaling that the Cybercab is preparing to enter the Robotaxi fleet in the coming weeks or months with this move. It seems more symbolic than anything; Tesla is ready to throw Cybercabs in the ride-hailing platform just as it did with Model Ys last year.
The addition of the Certificate of Conformity awarded to the Cybercab is another major factor working to Tesla’s advantage. The company now has permission from the EPA to allow the vehicle to operate on public roads and enter the chain of commerce. It’s officially street legal.
Tesla Cybercab specs revealed: range, curb weight, range ratings, and more
The big question that remains is whether Tesla will be able to operate the car without a safety monitor, especially considering it plans to put the car out there without a steering wheel or pedals. With the Cybercab only having a seating capacity of two, it is hard to believe Tesla will even consider putting a Safety Monitor in the car.
It did recently self-certify as Level 4 and has the ability to operate driverless vehicles in the State of Texas under a law that took effect on May 28. You can read more about that here:
Tesla’s Robotaxi dreams just took a massive step toward reality
We’d imagine Cybercabs will be on the roads as soon as July, but August will likely be a better estimate of when the car will be entered into the Cybercab fleet. It all depends at where Tesla is, as they’ve truly prioritized safety with the rollout of the Robotaxi platform.
Elon Musk has publicly questioned Moody’s credit assessments following the rating agency’s decision to assign SpaceX a Baa1 investment-grade rating, two notches above Tesla’s Baa3. The comments came amid discussions comparing the two companies’ financial profiles.
SpaceX earned its first-time Baa1 rating with a stable outlook from Moody’s. The agency highlighted the company’s leadership in orbital launches, the growing recurring revenue from its Starlink satellite network, strong vertical integration, U.S. government contracts, and emerging opportunities in AI infrastructure.
These factors were cited as supporting robust cash flows, margin expansion, and financial flexibility.
Musk responded directly: “Tesla’s credit rating is ridiculously low tbh,” and added, “Yeah, makes no sense. Tesla has over $40B in cash, no debt, and is consistently profitable!” His remarks underscored Tesla’s balance sheet strength and profitability at a time when many traditional automakers continue to report losses in the shift to electric vehicles.
Yeah, makes no sense.
Tesla has over $40B in cash, no debt and is consistently profitable!

Tesla maintains a leading position in the global EV market, with diversification into energy and storage, battery technology, and robotics through projects like Optimus. Recent financial updates show the company generated positive free cash flow of $1.4 billion in Q1 2026, supported by operating cash flow of $3.9 billion. Cash and short-term investments stood at approximately $44.7 billion.
Moody’s has affirmed Tesla’s Baa3 issuer rating with a stable outlook in periodic reviews, acknowledging the company’s EV leadership, technology strengths, including AI for autonomous vehicles, solid profitability, and strong liquidity.

However, the agency has also noted challenges in the automotive segment and expectations for margin pressures.
Musk’s critique highlights a common debate about how traditional rating methodologies apply to high-growth, capital-intensive technology companies. SpaceX benefits from long-term government-backed contracts and diversified, recurring revenue streams, while Tesla’s valuation reflects heavy investment in future technologies such as autonomy and robotics.
Both ratings remain investment-grade, yet the one-notch difference has fueled online discussion about potential inconsistencies in evaluating innovative firms.
The exchange comes as SpaceX explores financing options following its recent valuation milestones, while Tesla continues executing on its multi-year roadmap. Musk’s pointed response serves as a reminder that credit ratings, though influential for borrowing costs, represent one lens through which markets assess corporate strength—and that company leaders often view their financial positions through the lens of long-term innovation and cash generation rather than short-term risk metrics alone.
A new report from Reuters claims that a transport authority in Sweden is pushing back against the approval of Tesla’s Full Self-Driving suite because it will travel over speed limits.
The report says the Swedish Transport Administration (TRV) recommends the European Union votes against FSD’s approval. TRV believes it should not be approved until Tesla disables FSD’s ability to speed.
TRV sent a letter to the European Union’s Technical Committee on Motor Vehicles (TCMV), which is set to meet on June 30 to discuss the potential approval of the Tesla FSD suite in the country. Tesla, which has received various approvals in Europe over the past two months, has not provided a comment.
Teslas operating on FSD do travel over the speed limit, depending on the Speed Profile that is chosen. Drivers have the ability to disengage FSD at any point; Tesla specifically states that those supervising the suite are responsible for its actions.
Let’s cut to the chase: humans operating any vehicle speed almost daily in the United States. Realistically, speed limits in the U.S. are more frequently treated as speed minimums. However, other countries are different, and driving behaviors are less aggressive.
TRV believes that “allowing automated systems to systematically exceed legal speed limits…risks undermining both the legal framework and the expected safety benefits of vehicle automation,” the report stated. It’s surprising that Tesla has not received this claim from other countries previously.
This could be a good argument to bring Max Speed back, the setting that previously allowed the driver to choose the absolute fastest the car would travel.
This would still put the responsibility of supervision in the hands of the driver. It would allow the driver to choose whether the car would travel over the speed limit or not, acknowledging that they set the speed, and if they get pulled over, there would be no ability to argue it.
However, it does not seem as if this is something Tesla will do, especially considering many U.S. drivers have requested the feature in an effort to eliminate speeding or at least tone it down. The company has not shown any interest in bringing it back.
Tesla has approvals for FSD in Europe in Estonia, Lithuania, Denmark, the Netherlands, and Belgium.
