Tesla has formally updated the acceleration estimates for its Model S Performance sedan and Model X Performance SUV, with the electric cars now being capable of reaching 60 mph from a standstill in just 2.3 and 2.6 seconds, respectively.

The Model S Performance has always been Tesla’s fastest vehicle. As the company continues to improve its powertrain through Over-the-Air software updates, the car continues to shave tenths of seconds off of its listed 0-60 time.

Fresh off of its inclusion in a list from Autocar that names several EVs as some of the fastest-acceleration vehicles in the world, Tesla has subtracted an additional tenth of a second from the 2.4-second 0-60 mph estimate for the Raven Model S Performance. The flagship sedan’s newest builds are now listed with a 0-60 mph time of in 2.3 seconds, similar to a Lamborghini Huracán Performante.

Tesla also updated the Model X Performance’s acceleration by subtracting a tenth of a second from its 0-60 mph estimate. It went from an already blazingly-quick 2.7 seconds to an even more impressive 2.6 seconds. That’s similar to the 0-60 mph acceleration of the Lamborghini Aventador SV, a supercar.

While it is unknown why the acceleration estimates for both vehicles have been improved, speculations point to Tesla’s release of its “Cheetah Stance” Launch Mode that is exclusive to the two flagship vehicles. If there were a performance firmware update that stretched across all Performance vehicles, the 0-60 mph rating of the Model 3 and Model Y Performance would have lowered as well. However, only the Model S and Model X Performance received a revised rating, and both vehicles have the newly-released “Cheetah Stance” Launch Mode as their middle ground.

The new “Launch Mode” update was leaked by a Tesla hacker known as “@greentheonly” on April 3. The upgrade would utilize the air suspension system in the Model S and Model X to improve launches. Just after the release of the updated Launch Mode, Brooks Weisblat of the DragTimes YouTube channel tested that the acceleration of a Raven Model S Performance that received the Cheetah Stance update. As per Brooks’ test, the Model S Performance’s 0-60 mph time did improve by about a tenth of a second after the update.

Tesla’s two flagship vehicles are equipped with a 100 kWh battery pack, though Elon Musk has hinted that variants of the vehicle with bigger batteries are set to be released in the future. These could be represented by the Plaid Model S and Model X, both of which are expected to boast a more powerful powertrain that would allow owners of the vehicles to take to the track and not lose power despite driving multiple laps. The Plaid Model S was expected to be released later this year, though it remains to be seen if the vehicle will be pushed back due to the coronavirus pandemic.

The Tesla Robotaxi network will benefit from U.S. President Trump’s new self-driving rules.

The Trump administration is loosening regulations to support U.S. automakers like Tesla in developing self-driving cars. The United States government aims to outpace Chinese competitors in autonomous vehicle development. The policy shift, which was announced by U.S. Transportation Secretary Sean Duffy on Thursday, targets federal safety rules and crash reporting requirements to accelerate autonomous vehicle innovation.

The Transportation Department outlined exemptions allowing U.S. companies to bypass specific safety regulations for self-driving vehicles used in research, demonstrations, and non-commercial settings. Previously, such exemptions were applied mainly to foreign vehicles with standards different from those in the United States. The department also plans to streamline crash reporting rules, which Elon Musk has criticized, and move toward a unified national standard, replacing fragmented state regulations.

“We’re in a race with China to out-innovate, and the stakes couldn’t be higher,” said Transportation Secretary Sean Duffy in a statement. “Our new framework will slash red tape and move us closer to a single national standard.”

The regulatory changes align with Tesla’s ambitions in autonomous driving, particularly related to its Robotaxi network. On Wednesday, Musk confirmed during a Tesla investor call that the company is prepared to launch self-driving Tesla robotaxis in Austin, Texas, by June. Tesla’s Full Self-Driving (FSD) technology, a cornerstone of its robotaxi plans, could benefit from the eased rules, expediting testing and deployment.

The exemptions are designed to level the playing field for U.S. automakers, giving Tesla and others more flexibility to innovate. The administration aims to foster a competitive environment against Chinese firms advancing in autonomous vehicle technology by simplifying crash reporting and harmonizing regulations. Industry observers note China’s aggressive push for self-driving tech has pressured U.S. policymakers to act.

Tesla’s Austin Robotaxi rollout will be a key testbed for its FSD software under the new regulatory framework. The company has been refining FSD, with recent updates showcasing improved performance. The Transportation Department’s move could accelerate Tesla’s timeline for scaling its autonomous fleet, a critical step toward Musk’s vision of the Robotaxi network.

The policy shift underscores a broader U.S. strategy to maintain technological leadership. With Tesla at the forefront, the loosened rules could reshape the self-driving landscape, positioning American automakers to challenge global rivals.

Kia gains Tesla Supercharger access and issues a big apology

Kia gained Tesla Supercharger access and respect from Tesla fans in the same day.

Kia EV6, EV9 and Niro Owners Gain Access to Over 21,500 Tesla Superchargers

Kia has announced that owners of the EV6, EV9, and Niro EVs have officially gained access to over 21,500 Tesla Supercharger locations in North America.

However, its announcement also contained an apology to Tesla.

First, Kia said that its three EV offerings will have access to Tesla’s expansive Supercharger Network. More than 40,000 DC fast chargers are available to Kia EV drivers, a major uptick as Tesla Supercharger access nearly doubles the number of accessible piles.

Sean Yoon, President of Kia North America and Kia America, said:

“Kia is committed to an exceptional ownership experience, and expanding the network of available DC fast chargers to our EV customers is an important component to maintaining the brand’s leadership in electrified mobility. Now, with access to the Tesla Supercharger network of DC fast chargers, our EV owners can feel even more confident in their decision to purchase or lease a fully electric Kia vehicle.”

Kia owners who have a CCS1 Charging Port will have access to an NACS adapter through dealerships. This will enable compatibility, as current inlets are not NACS, the port that Tesla utilizes.

However, Kia will eliminate the need for this adapter starting with the 2025 EV6 and 2026 EV9. These will come standard with NACS inlets.

We mentioned Kia included somewhat of an apology to Tesla, which is related to social media posts from “certain Nordic distributors,” as the company puts it:

Kia said in its announcement:

Kia America is aware of marketing posts by certain Nordic distributors. These initiatives were developed entirely independently by those distributors, without direction from Kia AmericaKia Europe or Kia Global. We want it to be clear that these posts do not reflect the position of Kia America, and we remain committed to clear and professional communication that reflects our values.”

The company also said that it “condemns the recent attacks that disrupt the availability of convenient and affordable charging for our customers.”

Tesla adds new child protection feature to mobile app

Tesla is rolling out within its mobile app a new feature that aims to save the lives of those forgotten in the car.

Tesla is bolstering its in-car safety system with the addition of a new feature that aims to protect children left in the vehicle, an extension of a feature it introduced with the addition of 4D radar systems.

Children are, unfortunately, victims of accidents even when a vehicle is not in motion. A report from 2024 noted that 37 children under the age of 15 die each year because they are left in cars, usually dying from heatstroke.

Tesla has made a few attempts to eliminate the possibility of this happening. Back in September, coding from Software Update 2024.32 noted that the company would be using an alert system to warn people of children left behind:

Tesla set to roll out new child safety and navigation features, coding shows

This was enabled by the use of a wave sensor within the cabin, a piece of tech Teslarati found in a filing back in 2021 with the FCC.

The entire idea behind this addition to the vehicles was to alert owners if there were passengers left in the car.

Now, Tesla is adding another level of this to its mobile app, according to a decompile of the Version 4.44.0 update, which is rolling out to customers now.

Tesla App Updates on X revealed a “Child Left Alone Detection” feature in the new app version, which has a few strings from a software perspective:

  • Cannot turn off climate when Child Left Alone Detection is active
  • Climate failed to start. Climate is unavailable when Child Left Alone Detection is active.
  • Climate controls are disabled when Child Left Alone Detection is active
  • Unable to start software update while a child is detected in your vehicle

It appears that, if the vehicle detects a child or another occupant in the car, climate controls will be disabled through the app in an attempt to maintain a proper cabin temperature. Turning the temperature up or even turning climate control off from the app will not be possible.

This is a major update to this feature as it only bolsters the safety of the occupants in the event that they are left behind. Of course, many of us might ask, “How do you leave a child in the car?”

However, it happens, as past events have shown, and this is a great way to eliminate it from happening in Tesla vehicles.
