Tesla can fall short of its battery goals and still dominate rivals, says expert
In a recent interview with a German auto publication, battery expert Maximilian Fichtner remarked that Tesla could move far beyond the reach of its competitors, even if it fails to achieve all of the goals that were presented during Battery Day. This, according to Fichtner, is partly due to competitors not doing enough to further electric vehicle technologies.
In an interview with Spiegel Mobility, Fichtner, a director at the Helmholtz Institute and a professor for solid-state chemistry at Ulm University, remarked that German automakers are simply doing something much different compared to Tesla. While Tesla considers batteries as part of its core business, German automakers seemed to be content outsourcing all the battery work to third-party suppliers and focusing their efforts on competencies that they know best, such as body design.
“You outsource more things to suppliers. They only develop core components such as the engine themselves. Battery production is not considered a core business. One tries at some point to use proven methods to build an electric car that is equivalent to Tesla, only with better body gaps. Tesla, on the other hand, achieves a lead through technology by processing the entire production chain, from the integration of its own hardware and software to batteries and the finished car,” the expert noted.
When asked about improvements that Tesla could achieve with its next-generation cells, Fichtner stated that the company’s larger 4680 cells open the door to longer range and other upgrades. Such innovation, according to the expert, is a “quantum leap.” Fichtner added that with Tesla’s goal of reducing its battery production costs by 56%, the EV market could reach or even exceed price parity with the internal combustion engine, effectively rendering gas cars obsolete.
“(They) would be at costs of 70 to 80 US dollars per kilowatt-hour. There would be no more reason to buy a combustion engine – not even the price. That would be around 20,000 euros for a mid-range to upper-class vehicle,” he said, adding that “The cost reduction in two to three years would be extremely quick. When it comes to cell design, however, Tesla has calculated everything well and the better integration of the battery into the vehicle has been well thought out.”
Granted, Tesla’s goals for its next-generation batteries are very ambitious. Yet according to Fichtner, even if Tesla fails to achieve all of the goals it outlined in Battery Day over its self-imposed timeframe, the company would still be far ahead of the rest of the auto market. The battery expert noted that this is especially true for German automakers, some of which are still adopting strategies that were effective for the internal combustion engine.
“Even if Tesla only manages half of the expected increases in the difficult changes to the anode and a few percentage points less in the cell design, 40 percent more range remains. That would be around 700 instead of 500 kilometers on one charge. That’s a lot, based on almost conventional battery chemistry. Elon Musk has worked everywhere, from processing the raw materials to the finished car, to make his cars better and cheaper. Tesla apparently managed to turn both screws in the right direction. Even if the company only achieves a fraction of the growth announced, that is still far above what the competition in this country is planning,” Fichtner remarked.

Tesla Energy has introduced the Powerwall Lease in conjunction with Tesla Electric, making the service available in Texas. This new option delivers whole-home backup power using two Powerwall units for a net monthly cost of $35 after credits, accompanied by a low fixed electricity rate.
Under the lease terms, customers pay a one-time order fee of $100. The base lease payment for the two Powerwalls is approximately $122 per month during the first year, subject to a 3 percent annual escalator thereafter. Enrollment in a qualifying Tesla Electric Backup plan or Virtual Power Plant plan provides an $87 monthly credit.

This credit lowers the effective cost to roughly $35 per month plus applicable tax.
Installation of the standard system carries no additional charge. The package features Storm Watch for outage protection and allows complete management through a single Tesla application. The system supplies continuous whole-home backup capability.
The Powerwall system enables households to maintain electricity during severe storms that disrupt the utility grid. When outages occur, the batteries automatically provide seamless backup power to the home.

Tesla Storm Watch monitors weather forecasts and ensures the units are fully charged ahead of anticipated severe weather events so that power remains available throughout the disruption, keeping lights, refrigeration, and other essential systems operating without interruption.
Availability is restricted to select Texas locations where retail electric choice exists. Participants must lease exactly two Powerwall units and maintain continuous enrollment with Tesla Electric. Solar panels cannot be included under this particular lease arrangement.
The monthly credit activates automatically once the system is installed, receives permission to operate, and enrollment is confirmed. To retain the credit, customers are required to stay enrolled in Tesla Electric and fulfill all program conditions.
Nonstandard installations that involve electrical upgrades or special permitting may lead to extra expenses and might impact eligibility for the credit, so be sure to check with either your installer or Tesla to ensure you will still qualify.
Elon Musk continues to tease the unveiling event for the Tesla Roadster, a continuing trend that has grown into a bigger game of “When” for fans who have been waiting years for the car to finally enter production.
A video shared on X of the Joe Rogan Experience podcast that Musk appeared on last year, teasing the Roadster unveiling, was shared once again on the social media platform. The poster said the Roadster event will be “unforgettable.”
Musk agreed:
Yes

The timing is interesting because just yesterday, Musk said that we will be getting flying cars, and for years, Tesla has hinted that it could develop a SpaceX cold gas thruster package that would help the car float or fly for a short period of time.
It would be reasonable to assume Tesla’s major delays with this unveiling event are likely caused by the company’s need to break the rules and push the envelope on nearly everything. Last July, Lars Moravy, Tesla’s VP of Vehicle Engineering, said:
“Roadster is definitely in development. We did talk about it last Sunday night. We are gearing up for a super cool demo. It’s going to be mind blowing. We showed Elon some cool demos last week of the tech we’ve been working on and he got a little excited.”
The latest updates that Tesla has given us are that the Roadster is in design development, and it did have several potential dates for an unveiling event this year, including April. It was then pushed to August.
However, there are no clues as to when Tesla will be ready, and fans are certainly getting frustrated with the delays.
For what it is worth, Franz von Holzhausen told Jay Leno this week that the event would be “very soon.”
We sure hope.

Tesla’s driverless Cybercab just passed a big test with State Governor
Florida’s governor rode Tesla’s Cybercab at a closed test track and called the experience impressive.
Florida Governor Ron DeSantis rode in a Tesla Cybercab on a closed test track this week and came away impressed, posting on X that the vehicle “successfully navigated all hazards — a kid running into the street, a crash with police stopping traffic, a Model S cutting us off, etc.” He called the ride “impressive.”
The stop was part of a broader event Monday at SunTrax, a 775 acre state owned proving ground in Auburndale that Florida built specifically to test autonomous and connected vehicles before they reach public roads. Standing next to a gold Cybercab, DeSantis described the car in plain terms: “You go in there and you just sit. You have a screen. There’s no steering wheel, no pedals. Clearly these things could be very beneficial.”

DeSantis paired the praise with a caveat that has followed autonomous vehicles since the category existed. “You don’t want to be in an autonomous vehicle and it drives you into a ditch. That would not be good,” he said, framing safety validation as the gate before wider deployment.
SunTrax, the 2.25 mile oval which the state calls the only high speed autonomous vehicle test track in the Southeast, can simulate rain, pedestrian crossings, hills and crowded urban conditions at highway speeds, letting companies push a car past what an early public rollout would risk. Tesla, Waymo and Beep all use the facility, and Florida’s regulatory approach, among the most permissive for autonomous vehicles in the country, doesn’t require a human operator inside a fully autonomous car.
Tesla has reason to want the blessing of Florida and states beyond, as the Cybercab entered volume production at Gigafactory Texas this spring and has since self certified as SAE Level 4 under Texas law. Public road testing so far has kept a safety monitor in the passenger seat, and Florida is where Tesla has been expanding its existing Model Y based Robotaxi service instead, adding Miami in July and then Orlando and Tampa two weeks later. A closed track endorsement from a sitting governor doesn’t change any of that, but it does put Tesla’s newest hardware in front of a state that has already shown it will move fast on rules.
