Tesla has said that its wireless charging system for the Cybercab has a charging efficiency of “well over 90 percent,” in response to questions about whether the system would be inefficient compared to wired charging.
Tesla made the claim on Saturday after tech reviewer Marques Brownlee, better known as MKBHD, highlighted the “massive heat waste” in wireless charging systems in a post on X, claiming that a “noble goal” in wireless charging for electric vehicles (EVs) would only reach “maybe 75 percent efficiency.”
In response, Tesla plainly stated that the system’s “efficiency is well above 90 percent,” eliciting an eyes emoji from Brownlee.
“I stand corrected. Can’t wait for it to ship,” Brownlee wrote, after being encouraged to say more by another user.
Efficiency is well above 90%

Tesla teases Cybercab inductive charging and robot cleaning system
The news comes after Tesla’s “We, Robot” event earlier this month, during which Elon Musk said that the newly unveiled Cybercab would be charged wirelessly with inductive charging, instead of including an NACS port.
Although wireless charging was expected to play a role in the company’s future robotaxi plans, it wasn’t until the “We, Robot” event that such a system was actually teased. During the presentation, Tesla also showed a Cybercab charging at 19kW at 35 state-of-charge (SoC), outpacing the roughly 11.5kW offered by the company’s Wall Connector.
Before the event, some expected wireless charging to play an important role in the robotaxi system, given that the company also patented a wireless charging pad in September. In July, Tesla also patented the automatic cleaning system that would later go on to be teased alongside the inductive charger.
Then, in a video shared by Tesla on Thursday (the one that sparked the discussion between Brownlee and others), the automaker shows a vehicle with 25kW of charging power. The video also highlights Tesla’s focus on autonomy, including driving, cleaning, and charging, with the Cybercab now expected to be able to be operated with “no hands required,” as the company says in the post.

Tesla was also thought to be getting into wireless charging as early as last year, when the company acquired wireless charging company Wiferion, which had been rumored leading up to the news. The company would later go on to sell Wiferion, though it has kept some of the company’s engineers who came onboard with the acquisition.
Teslarati was also in attendance at the “We, Robot” event, at which Tesla unveiled both its two-seater Cybercab and its larger autonomous “Robovan,” set to be a 12- to 14-seat self-driving bus. You can check out our first ride in the Cybercab below.

BYD is under investigation for violating the EU’s EV subsidy rules
The EU is investigating BYD for allegedly using unfair subsidies in its Hungary EV plant.

China’s top automaker, BYD, is under investigation by the European Union for violating the EU’s electric vehicle (EV) subsidy rules.
According to the Financial Times, BYD received unfair subsidies from China which were used in its electric car plant in Hungary. Subsidies from the Chinese government are the main reason the EU Commission decided to implement additional tariffs on exported electric vehicles made in China and sold in Europe. The subsidies from China reportedly enabled car manufacturers to make China-made EVs cheaper in the EU market, affecting Europe’s local OEMs and competition in the domestic market.
The European Commission is in the early stages of a foreign subsidy probe into BYD’s EV plant in Hungary. If the Commission finds evidence that China provided subsidies to BYD’s EV plant in Hungary, it may force the Chinese automaker to sell some assets, reduce capacity, repay the subsidy, and pay a fine for non-compliance.
In October 2024, enough member states of the European Union voted to impose additional tariffs on China-made electric vehicles.
“Today, the European Commission’s proposal to impose definitive countervailing duties on imports of battery electric vehicles (BEVs) from China has obtained the necessary support from EU Member States for the adoption of tariffs. This represents another step towards the conclusion of the Commission’s anti-subsidy investigation,” announced the Commission after the EU member states’ vote.
The European Union imposed a 17.0% levy on BYD specifically, on top of the EU’s standard car import duty of 10%. Geely received an additional duty of 18.8%, while SAIC received a tariff rate of 35.3%. Most automakers who build cars in China and export to Europe will have a duty of 35.3%. Only a few automakers, like Tesla and BYD, have an assigned duty rate.
Tesla invited the EU Commission to inspect its operations in Shanghai to determine a separate tariff rate for its China-made EVs exported to Europe. Tesla received a duty of 7.8% after the investigation.

Tesla owners doxxed by controversial anti-DOGE website in clear intimidation tactic

Tesla owners are being doxxed by a controversial anti-DOGE website in what it called an act to “empower creative expressions of protest.”
Dogequest, a website that has been created with a clearly outlined use for intimidation against Tesla owners, posted the names, addresses, phone numbers, and other contact information of those who own vehicles made by the electric vehicle manufacturer.
It was spotted by 404 Media.
The site also claims to have the information of employees at the Department of Government Efficiency, as well as the addresses of Tesla dealerships and the locations of Tesla Superchargers. The latter two are public information.
However, the website is hoping to get Tesla owners to sell their vehicles in this evident intimidation tactic. However, the information on the website, while it was seen, was not verified to prove that it contained the information of real-world Tesla owners. The site was not accessible by Teslarati at the time of publication.
The creation of a site like Dogequest is just another level that anti-Elon Musk activists are taking to attempt to destroy a company like Tesla as its CEO works with the Trump Administration to eliminate excessive government spending through the work of DOGE.
It is also the latest attack on Tesla owners, who have seen their vehicles vandalized, damaged, and even destroyed by those who disagree with the actions of Musk.
Tesla as a company has also seen several acts of retaliation against it, as everything from the arson of its showrooms and vehicles to it being kicked from the popular Vancouver Auto Show have come as a result of the recent backlash against the company.
Moving forward, there are still questions surrounding how these attacks will be combatted. The Trump Administration has indicated that acts of vandalism against Tesla would be considered a federal crime, but the tricky part of locating the culprits has proven to be extremely difficult. Only a handful have been found and held accountable.

Tesla gets an upgrade on ‘upcoming material catalysts’

Tesla (NASDAQ: TSLA) received an upgraded rating on its shares from Wall Street firm Cantor Fitzgerald, who recently took a trip to Austin to visit the company’s data centers and production lines ahead of several high-profile product launches set for this year.
It was a bold move, especially considering Tesla shares are under immense pressure currently, fending off negative news regarding the company’s sentiment and potentially lower-than-expected delivery figures due to the launch of a new version of its most popular vehicle, the Model Y.
However, the bulls on Wall Street are still considering Tesla to be a safe play, especially considering its robust presence in various industries, including automotive, energy, and AI/Robotics.
Cantor Fitzgerald analyst Andres Sheppard said in a note that, during a recent visit to Tesla’s Cortex AI data centers and the production line at Gigafactory Texas, it was clear there is a lot of potential and runway for Tesla in 2025:
“On 3/18, we visited Tesla’s Cortex AI data centers and the factory’s production lines ahead of the company’s introduction of its Robotaxi segment (targeted for June in Austin, followed by CA later in 2025). With Tesla’s shares now down ~45% YRD, we upgrade Tesla to Overweight (from Neutral) ahead of upcoming material catalysts. Our $425 12-month PT is unchanged. Our Thoughts: Attractive Entry Point Ahead of Material Catalysts.”
Sheppard went on to mention the catalysts, which he believes are the Robotaxi rollout in Austin in June, along with the continued rollout of Full Self-Driving in China, the eventual rollout of FSD in Europe, and the introduction of the affordable models in the first half of this year, and those were just on the automotive side.
There are several others, including Optimus, growth in the energy division, and in the longer term, the Semi.
In terms of potential weaknesses, Sheppard expects the likely removal of the EV tax credit and some of its growth to be offset by tariffs as the two big things that stand in the way of even more growth for the company.
Tesla is up over 5 percent on Wednesday, trading at $236.86.
