Panasonic President Kazuhiro Tsuga, who leads Tesla’s primary battery supplier, recently shared some insights about the electric car maker’s in-house production of its custom-designed 4680 cells. According to the Japanese executive, Tesla’s in-house battery production program does not mean that the American EV maker will be a direct competitor to Panasonic. 

Tsuga’s statements were expressed in an interview with newswitch.jp, where the Panasonic President discussed several aspects of the tech conglomerate’s initiatives, from its solar cell business to its television division. Most interestingly, Tsuga discussed Panasonic’s ongoing plans with Tesla amidst the electric car maker’s transition to its new, larger, and more affordable 4680 cells.

The Panasonic President noted that the development of the 4680 cells for Tesla are already underway, though he did note that some challenges remain with regards to the production ramp of the batteries themselves due to their high capacity. Yet despite this, Tsuga highlighted that Panasonic is not concerned about Tesla becoming a rival in the future. 

“We have begun development of a new automotive battery, the 4680, for Tesla in the United States. The electrode structure is difficult because of its high capacity. The electrode structure is difficult because of its large capacity. We will make prototypes in Japan and establish a manufacturing method. High reliability is one of our strengths. There is no concern that Tesla will become a competitor (although Tesla is promoting in-house production of the battery),” Tsuga said

Panasonic has been a longtime partner for Tesla’s initiatives, with the Japanese tech conglomerate being heavily involved with the buildout and ramp of Gigafactory Nevada, an expansive facility where the electric car maker’s current 2170 cells are being produced. While Tesla has since established battery supply deals with South Korean firm LG and China-based CATL, Panasonic seems poised to continue its deep ties to the electric car maker. 

This was highlighted recently, with a Form 8-K submitted to the United States Securities and Exchange Commission revealing that Tesla and Panasonic have entered into a 2021 pricing agreement for battery cells that are manufactured in Japan, which are typically used for the Model S and Model X. Tesla halted the production of the flagship sedan and SUV at the Fremont factory last month, fueling speculation that some notable updates for the two vehicles are underway.

Tesla’s new Safety Report for Q3 shows Autopilot technology contributed to accident frequency that was nine times lower than the national average.

Tesla released its Vehicle Safety Report for Q3 2025, and it showed that one crash was recorded every 6.36 million miles drive in which drivers were using Autopilot technology.

This is a stark contrast from the most recent data made available by the National Highway Traffic Safety Administration (NHTSA) and Federal Highway Administration (FHWA), which shows there is an automobile crash approximately every 702,000 miles.

The figure for Q3 2025 is slightly lower than the one that Tesla released in Q3 2024, which eclipsed 7 million miles between accidents for drivers using Autopilot technology.

Over the past seven quarters, Q1 has been Tesla’s strongest showing with the Vehicle Safety Report, with Q4 being the weakest. This is usually attributed to weather and driving conditions deteriorating toward the end of the year.

Q1 2024 was Tesla’s best performance so far, with one crash every 7.63 million miles.

Tesla releases Vehicle Safety Report for Q1 2024

Autopilot and Full Self-Driving have been a major focus of Tesla over the past few years, and recent versions have improved on what has already proven to be an extremely safe way to travel, as long as it is used correctly.

Tesla’s Full Self-Driving (Supervised) suite is a suitable way to allow the vehicle to navigate through any traffic setting and has been widely effective for day-to-day travel. With the data Tesla gets from its use across its vehicle fleet, it gets more refined and more accurate with every passing mile.

The company has teased the potential for completely unsupervised Full Self-Driving releases in the future, but Tesla has to solve autonomy before it can offer anything like that to the public.
