Volkswagen boss Diess tells execs third-party software fix isn’t an option

Volkswagen boss Herbert Diess is adamant that the German car company must develop its electric vehicle software in-house. In a recent meeting with executives, Diess outlined Volkswagen’s core needs in the topic of software, indicating that it must be developed in-house and that sourcing effective and dependable software from a notable tech company simply isn’t an option if the company wants to remain independent.

“If we want to retain our independence,” Diess told his top managers in a recent meeting, “we have to be able to develop the software in the car ourselves. This is the only way for us to guarantee long-term success.”

Volkswagen’s EV project, which has been catalyzed by the introduction of the ID. family of vehicles has been a thorn in the side of the world’s leading car company since its introduction. While Volkswagen has made electric models before, they have not been on the company’s new MEB (Modular electric drive matrix) platform designed for electric cars. The platform requires a robustly accurate and scalable software program, something that Volkswagen has encountered several problems with early on in its electric offensive.

But the roadblocks and bottlenecks in Volkswagen’s software are not issues that Diess is willing to have someone else fix. He expects his competent software engineers and other team members to figure out the shortcomings on their own in an attempt to remain free of dependence on another company, whether it would be a tech company like Apple or a fellow electric automaker like Tesla.  “We must not hand over data sovereignty, the customer interface, and ultimately the “brain” of the car to the big tech players.”

The software essentially acts as the brain of the car. To give owners a more pleasurable ownership experience, the software needs to be free of any discrepancies. The issues can cause things as small as voice recognition to go awry or things as large as software updates to be uninstallable, making a vehicle outdated and, in some cases, unusable. Volkswagen has had its fair share of issues with the MEB platform, but it claims that many of the difficulties it has encountered are solved. Additionally, it has promised owners that software updates will be ready to be downloaded to cars regularly beginning Summer 2021.

Volkswagen's software issues with the ID.3 are worse than reported: 'It is an absolute disaster'

With automakers big and small fighting to keep pace with Tesla, Diess understands the urgency of the project at hand. “This is by far the most important project for this Group in the next five, probably ten years,” he said, according to Business Insider. Automakers are being forced to adapt or be left behind as Tesla extends its lead in the sector, especially in software. While other car companies like Ford are releasing highly-competitive vehicles like the Mustang Mach-E, which has proven to be a notable adversary to the Tesla Model Y, the sector is only becoming more concentrated on what seems like a daily basis. With new companies coming around, focusing purely on electric powertrains, legacy automakers have almost dragged their feet through the proverbial mud, only delaying the inevitable: they will fall behind if they do not focus on electrification.

Volkswagen is arguably the most invested legacy automaker in the EV transition. Diess has been extremely vocal regarding VW’s transition to electric cars, recognizing that the market will only become more competitive, more robust, and more concentrated. A lead now could extend into several decades and make Volkswagen more desirable than other car companies who will confront these same issues in a few years.

Tesla’s $2.9 billion bet: Why Elon Musk is turning to China to build America’s solar future

Tesla looks to bring solar manufacturing to the US, with latest $2.9 billion bet to acquire Chinese solar equipment.

Published

By

Tesla is reportedly in talks to purchase $2.9 billion worth of solar manufacturing equipment from a group of Chinese suppliers, including Suzhou Maxwell Technologies, which is the world’s largest producer of screen-printing equipment used in solar cell production. According to Reuters sources, the equipment is expected to be delivered before autumn and shipped to Texas, where Tesla plans to anchor its next phase of domestic solar production.

The move is a direct extension of a vision Elon Musk has been building for months. At the World Economic Forum in Davos this past January, Musk announced that both Tesla and SpaceX were independently working to establish 100 gigawatts of annual solar manufacturing capacity inside the United States. Days later, on Tesla’s Q4 2025 earnings call, he made the ambition concrete: “We’re going to work toward getting 100 GW a year of solar cell production, integrating across the entire supply chain from raw materials all the way to finished solar panels.”

Job postings on Tesla’s website reflect that same target, with language explicitly calling for 100 GW of “solar manufacturing from raw materials on American soil before the end of 2028.”

The urgency behind the latest solar manufacturing target is rooted in a set of rapidly emerging pressures related to AI and Tesla’s own energy business. U.S. power consumption hit its second consecutive record high in 2025 and is projected to climb further through 2026 and 2027, driven largely by the explosion in AI data centers and the broader electrification of transportation. Tesla’s own energy division, which produces the Megapack utility-scale battery storage system, has been growing rapidly, and solar supply is a critical companion component for the business to scale. Musk has argued that solar is not just a clean energy option but the only one that makes economic sense at the scale AI infrastructure demands.

Ironically, the path to domestic solar independence currently runs through China. Sort of.

Despite Tesla’s stated push to localize its supply chain, mirrored recently by the company’s plan for a $4.3 billion LFP battery manufacturing partnership with LG Energy Solution in Michigan, Tesla still relies on China-based suppliers to keep its cost structure intact.

The $2.9 billion equipment deal underscores a tension Musk himself acknowledged at Davos: “Unfortunately, in the U.S. the tariff barriers for solar are extremely high and that makes the economics of deploying solar artificially high, because China makes almost all the solar.” Building the factory in America requires buying the machinery from the country Tesla is trying to reduce its dependence on.

The regulatory pathway adds another layer of complexity. Suzhou Maxwell has been seeking export approval from China’s commerce ministry, and it remains unclear how quickly that clearance will come. Still, the market has already reacted, with shares in the Chinese firms reportedly involved in the talks surged more than 7% following the Reuters report that broke the story.

Whether Tesla can hit its 2028 target of 100GW of solar manufacturing remains an open question. Though that scale may seem staggering, especially in such a short timeframe, we know that Musk has a documented history of “always pulling it off” in the face of ambitious deadlines that may slip. But, rest assured – it’ll get done.

Elon Musk reveals date of Tesla Full Self-Driving’s next massive release

Initially planned for a January or February release, v14.3 aims to add some reasoning and logic to the decisions that Full Self-Driving makes, which could improve a lot of things, including Navigation, which is a major complaint of many owners currently.

Tesla CEO Elon Musk revealed the date of Full Self-Driving’s next massive release: v14.3.

For months, Tesla owners with Hardware 4 have been utilizing Full Self-Driving v14.2 and subsequent releases. Currently, the most up-to-date FSD version is v14.2.2.5, which has definitely brought out mixed reviews. With releases, some things get better, and other things might regress slightly.

For the most part, things are better in terms of overall behavior.

However, many owners have been looking forward to the next release, which is v14.3, about which Musk has said many great things. Back in November, Musk said that v14.3 “is where the last big piece of the puzzle lands.”

He added:

“We’re gonna add a lot of reasoning and RL (reinforcement learning). To get to serious scale, Tesla will probably need to build a giant chip fab. To have a few hundred gigawatts of AI chips per year, I don’t see that capability coming online fast enough, so we will probably have to build a fab.”

Initially planned for a January or February release, v14.3 aims to add some reasoning and logic to the decisions that Full Self-Driving makes, which could improve a lot of things, including Navigation, which is a major complaint of many owners currently.

Tesla Full Self-Driving v14.2 is a considerable improvement from early versions of the suite, but we have written about the somewhat confusing updates that have come with recent versions.

Tesla Full Self-Driving v14.2.2.5 might be the most confusing release ever

They’ve been incredibly difficult to gauge in terms of progress because some things have gotten better, but there seems to be some real regression on a handful of things, especially with confidence and assertiveness.

Musk confirmed today on X that Tesla is already testing v14.3 internally right now. It will hit a wide release “in a few weeks,” so we should probably expect it by late April.

Overall, there are high hopes that v14.3 could be a true game changer for Tesla Full Self-Driving, as many believe it could be the version that Robotaxis in Austin, Texas, some of which are driverless and unsupervised, are running.

It could also include some major additions, including “Banish,” also referred to as “Reverse Summon,” which would go find a parking spot after dropping occupants off at their destination.

What Tesla will roll out, and when exactly it arrives, all remain to be seen, but fans have been ready for a new version as v14.2.2.5 has definitely run its course. We have had a lot of readers tell us their biggest request is to fix Navigation errors, which seem to be one of the most universal complaints among daily FSD users.
