Porsche’s software update for the Taycan falls short of Tesla’s over-the-air model

In the years before the Taycan’s unveiling, Porsche stated that the all-electric sedan, then called the Mission E, will feature over-the-air updates. Such a function would provide the all-electric Porsche a comparable ownership experience to Tesla’s vehicles, which receive consistent OTA updates every few weeks. 

This was mentioned by Porsche CEO Oliver Blume, who noted that some of the Taycan’s OTA updates would allow a 400-hp version of the Mission E to be bumped to 450 hp. Such statements definitely suggest a Tesla-like update process, but if a recent letter from the German automaker is any indication, it appears that software updates for the Taycan will be a bit more old-fashioned, at least for the time being. 

In a letter shared by Nicolas Boehmer on LinkedIn, the automaker stated that OTA updates are only used for the Taycan’s smaller patches for now. When it comes to major updates, Taycan owners would have to drive over to a Porsche Center to have the update manually loaded onto their vehicle. This, according to Porsche, is partly due to the size of the update itself, since physical centers have a high-speed internet line. 

“The OTA system is already used for updates of a smaller scope. However, for compound updates such as this one, such a large amount of data is transferred that a smooth update in the Porsche Center is ensured with a high-speed line. Subsequently, the function of all control units is verified with a test. With a technology carrier such as the Taycan, the complexity of the systems is at a very high level, so we decided on this procedure,” the company wrote. 

As noted by Mario Herger of The Last Driver License Holder, the size of the software update likely has little to do with Porsche’s decision to conduct manual updates for the Taycan. Tesla, for example, regularly rolls out software updates that are worth hundreds of megabytes or even gigabytes of data, and they are usually downloaded using a mobile network or on a regular home broadband connection without issue. With this in mind, Herger stated that the complexity mentioned by Porsche likely refers to the Taycan’s electronics, which are far more complex than those found in Tesla’s electric cars.

Tesla is vertically-integrated, and it manufactures a significant number of its vehicles’ components in-house. This allows Tesla to simplify its cars’ electronics architecture with relatively few ECUs and AI chips. Traditional automakers do not follow this model, with the Taycan’s electronics reportedly having over 100 ECUs, many of which are from varying manufacturers. This ultimately makes it very difficult to coordinate regular software updates, which likely encouraged Porsche to simply perform the Taycan’s software upgrades manually. 

“The coordination of a software update with so many suppliers is certainly no honeypot and the Porsche management seems to have taken the easiest way to periodically order Taycan owners to the workshop for an update. The fact that Porsche itself has to adjust to a rhythm of software updates lasting several weeks is challenge enough. If dozens of suppliers have to be coordinated, the complexity increases enormously,” Herger wrote. 

That being said, Porsche still deserves some recognition for actually following through and rolling out a legitimate software update for the Taycan. As the company continues its push for electric vehicles with the Taycan Cross Turismo and the electric Macan, there may be a chance for the automaker to be more vertically-integrated in the near future.

Tesla has created a clever solution to simplify and improve its Service. Tesla performs most of the services that are needed on its vehicles at its company-owned Service Centers.

However, service has been a weak point of the company, as some regions have fewer Service Centers than others. This can cause long wait times for Tesla owners in some parts of the country.

There are also instances where customers do not agree with what Tesla is saying about their vehicle. In fact, one instance that revealed this new change Tesla is making to its Service was precisely that.

One owner posted on X that his vehicle’s battery seal had failed after a recall was issued. Tesla insurance and Tesla Service both did not assist, and it took CEO Elon Musk stepping in to get the issue resolved:

Another owner suggested there should be a more streamlined communications process between the customer and the Service Center, a solution that has been missing.

Raj Jegannathan, a Vice President of IT/AI-Infra, Apps, Infosec, and Vehicle Service Operations, revealed that Tesla has started a small pilot program at a few service locations to combat this issue.

Jegannathan said that Tesla has started to share local and regional leader contact information so customers have the ability to reach out when they have complaints or disagree with warranty claims, changes in estimates, or initial diagnostics.

It is available in a handful of locations already, and Jegannathan said that once abuse guardrails are built, this will expand to all locations:

This would be a major improvement in the Service portion of Tesla’s business. There are common disagreements between Service and customers, specifically when Service’s suggestions don’t align with the customer’s beliefs.

When it comes to things like a warranty claim, these issues are not really up for interpretation. Instead, the repairs should be made. If there is a misunderstanding on Service’s side, a simple message from the customer could have resolved the issue. That’s basically what happened here.

Tesla gets its best analysis from Morgan Stanley as ‘it’s all about to change’

He maintained its ‘Overweight’ rating and the $410 price target Morgan Stanley had on the stock.

Tesla has gotten perhaps its best analysis from Morgan Stanley in quite some time, as the Wall Street firm claims that “it’s all about to change.”

That phrase could be used for both the company’s status and the world in general.

Analyst Adam Jonas said in a new note on Thursday to investors that Tesla could be one of the major winners in terms of the global transition from what it is now to what it will be.

He describes the global shift that will occur over the next few years:

“Have you interacted with a robot today? Have you even seen a robot today? No? Well, take a mental picture because it’s all about to change. When we meet someone who has never been in a Waymo or a Tesla Cybercab (which is most people), we frequently see a wince and a response such as ‘I’m not sure I’d feel comfortable getting in a car without a driver.’ We imagine going back in time to 1903 and asking people if they’d feel comfortable in an airplane.'”

The same technological revolutions that have occurred over the past 150 years will continue to occur again and again. We are on the verge of another, Jonas believes, as companies like Tesla are working on artificial intelligence tech, which includes changing the way we look at things like transportation and labor.

Jonas includes an interesting tidbit in his note about how humanoid robots could change wages, and how it could work into the advantage of Tesla, especially as it is developing its own Optimus robot:

“We estimate 1 humanoid robot at $5/hour can do the work of 2 humans at $25/hour, generating an NPV of approximately $200k/humanoid. 1 robot shaped car can potentially drive down cost/mile of a ride share vehicle to <$0.20 mile (1/10th human-driven ride-share).”

Jonas sees Tesla as a key player in how AI will impact things like manufacturing and various automotive industries, and he believes there is long-term potential for AI, robomobility, and even autonomous eVTOL platforms.

Tesla is expanding its Robotaxi program in Austin, Texas, as several people have received invitations to participate and take rides.

Tesla first launched the Robotaxi platform on June 22. It invited a handful of people to participate in the first-ever public rides. We were lucky enough to get an invitation, and our permissions have been expanded in the Bay Area pilot program as well.

The group was small and consisted of big names in the Tesla community. It expanded and is continuing to offer these exclusive invitations to notable members of the Tesla community.

There have been fewer than five subsequent invitations after the first group’s were sent in late June:

“We are being very cautious. We do not want to take any chances, so we are going to go cautiously. But the service areas and the number of vehicles in operation will increase at a hyper-exponential rate,” CEO Elon Musk said during the Q2 Earnings Call.

Eventually, the Robotaxi platform will not require an invite, and it will operate without geofences. Musk believes Tesla can get there within three or six months, and plans to have at least half of the U.S. population with access to a Robotaxi by the end of the year:

“I think we will probably have autonomous ride-hailing in probably half the population of the U.S. by the end of the year. That’s at least our goal, subject to regulatory approvals. I think we will technically be able to do it. Assuming we have regulatory approvals, it’s probably addressing half the population of the U.S. by the end of the year.”

Tesla plans to have regulatory approval in Nevada, Arizona, and Florida sooner than in other states.
