Tesla Model S shows drastic consistency improvements after update, ties Taycan in Car & Driver test
Back in February, esteemed motoring publication Car and Driver pitted the Tesla Model S Performance against the Porsche Taycan Turbo S. And while the publication ultimately granted the win to the Model S due to its value for money, the tests showed that the Taycan had the better performance between the two vehicles. This was especially true when it came to consecutive quarter-mile runs.
The Model S shone against the Taycan in rolling-start 5-60 mph runs, but in actual sprints to the quarter-mile, the Tesla ended up being slower than the Porsche. The publication noted that on its hero run, the Model S Performance was able to hit 60 mph in 2.5 seconds, which was only 0.1 seconds slower than the Taycan Turbo S’ 2.4 seconds. However, the gap between the two cars was about 3 seconds by 150 mph.
Shockingly, the Model S’ 0-60 mph times fell off rapidly after its first couple of runs, and by the 15th launch, the flagship Tesla sedan was hitting highway speeds nearly at the pace of the Chevy Bolt EV. That was the case, at least, until Tesla rolled out its Cheetah Stance update for the Model S. Once that was rolled out, everything changed.

With the exact same car on hand, Car and Driver opted to retest the Model S Performance’s capabilities with its Cheetah Stance update. The only difference was that this time, the test track used for the all-electric sedan’s launches was in Michigan instead of Southern California. Needless to say, the Tesla Model S got better after its update — a whole lot better.
The hero run of the Model S Performance was already impressive back in February, but with its Cheetah Mode update, the vehicle was able to show a 0-60 mph time of 2.4 seconds, matching the Taycan Turbo S’ best time. Inasmuch as the results from this past February were shocking, the results from the Model S’ retest were equally astounding. The vehicle’s 0-60 mph time only ranged from 2.7 to 3.8 seconds, and quarter-mile passes ranged from 11.3 to 12.9 seconds.
Ultimately, after 15 consecutive launches, the average time in both metrics dropped by around 2 seconds compared to the tests last February. This stunning improvement in consistency, which was evidently only due to new software, was something that truly impressed Car and Driver.
“Across all 15 runs, the average time in both metrics dropped by a massive two seconds compared to our previous test. That’s a staggering gain in performance from twiddling a few lines of code, and we continue to marvel at the breadth and depth of the changes Tesla is making with its continual software updates,” the publication wrote.
What is rather interesting is that the Tesla Model S Performance today is not done receiving improvements from the electric car maker. Tesla stands apart from the competition with its mastery of over-the-air software updates, and if Car and Driver’s tests are any indication, these improvements are incredibly evident. It could, for one, match the consistency and performance of a flagship electric car like the Porsche Taycan Turbo S, at a fraction of the price.

Tesla Full Self-Driving (Supervised) v14.1.7 real-world drive and review
On an hour-long drive, we tested v14.1.7 and tested its new capabilities, which are mostly overall performance and smoothness fixes rather than integrations of new features that are unknown to routine FSD users.
Tesla started rolling out its Full Self-Driving (Supervised) v14.1.7 suite last night to owners, and there are several improvements to note within the new update that are at least the start of fixes to highly-mentioned issues.
On an hour-long drive, we tested v14.1.7 and tested its new capabilities, which are mostly overall performance and smoothness fixes rather than integrations of new features that are unknown to routine FSD users. However, there are a handful of shortcomings that are still present within the suite, which are not something that will be fixed within the span of a single update.
For what it is, Full Self-Driving does an excellent job of navigating — once you get it on its correct path. Our issues tend to be confined to navigation, routing, and the decision-making process that has to do with the way the car wants to get you to your destination. There were five things that happened on our first drive with v14.1.7 that are worth mentioning. The full drive will be available at the bottom of this article.
Navigation and Routing Still Seems to Be a Major Challenge
In past content, we’ve discussed the issues with routing and navigation, and how a Tesla chooses its path. Most noticeably, these issues occur in the same areas; for me, it’s my local Supercharger. My 2026 Model Y with AI4 continues to pick less-than-optimal routes out of the Supercharger, and in this instance, it actually chose to turn down a road, pull over, and give me the wheel, essentially asking, “Hey, can you get me on the right track here?”
This is still my biggest bone to pick with FSD, even more so than some of the bonehead moves it’s made in tougher scenarios (mostly parking lots with very limited visibility due to shrubs being planted in the worst possible locations). It’s rare that it happens, but this particular Supercharger has been a true thorn in the side of my Tesla.
This is not an issue that is confined to v14.1.7, or even v14 in general. Unfortunately, it is an issue that has persisted throughout my ownership experience, as well as during Demo Drives.
Still dealing with this Navigation/Routing issue. FSD still hasn’t figured out how to exit this Supercharger.

Stuttering and Hesitation at Intersections was Non-Existent
There was some confusion regarding my language in a recent article where I stated Tesla is confronting the issues that have been reported regarding the “stabbing” with braking.
“Tesla began the v14.1.4 launch last night, which included minor improvements and addressed brake-stabbing issues many owners have reported. In my personal experience, the stabbing has been awful on v14.1.3, and is a major concern.
However, many things have improved, and only a couple of minor issues have been recurring. Many of the issues v13 addressed are no longer an issue, so Tesla has made significant progress.”
It has undoubtedly improved, but it is not resolved.
With that being said, I did not feel a single example of hesitation, stabbing, or stuttering at a single intersection or instance when it has been present in the past. CEO Elon Musk said it would be fixed with v14.2, so it seems like Tesla is well on its way to resolving it.
Proper Handling of Crosswalks
It’s crazy how many people still do not stop for pedestrians at clearly-marked crosswalks. I had two instances of it happen during the drive, with FSD stopping for those pedestrians both times.
Human drivers did not stop either time:

Handled Merging onto a Highway with an Inconsiderate Driver Well
Routinely, drivers will get over into the left lane, if they are able, to allow merging traffic to safely enter the freeway. It does not always happen this way, and it’s not required by law.
Not exclusive to v14.1.7, as many past iterations would have done this as well, but it was nice to watch the vehicle slow down to let that traffic pass. It then entered the freeway safely, and the entire maneuver was well done.

Took an Appropriate Move with Oncoming Foot Traffic and Debris in a Tight Alleyway
This was probably the most on-edge I was during the drive because: 1) FSD chose to take an unnecessary alleyway, and 2) there was a box and oncoming pedestrians.
The car was aware of everything that was going on. In order to avoid the box, it would have had to turn toward the pedestrians, and in order to avoid the pedestrians, it would have had to turn into the box.
It chose to wait patiently, and after the pedestrians were past the car, FSD chose to proceed.
A patient FSD debates pedestrians and debris.
It chooses to not turn toward the humans or the box, instead waiting for a clear path to proceed. EXCELLENT and my favorite part of the drive pic.twitter.com/JNVxuxkhmn— TESLARATI (@Teslarati) November 13, 2025
Closing Thoughts
Overall, we’re very impressed with v14.1.7, and we think this is Tesla’s best iteration of the FSD suite yet, as it should be since it’s the newest version available. Tesla’s attention to detail regarding the brake stabbing is really well done, and it seems evident that a complete fix is on its way.
Other than the navigation issue at the very beginning, which was not an intervention, at least in my opinion, this was a really successful drive.

Elon Musk debunks report claiming xAI raised $15 billion in funding round
xAI also responded with what appeared to be an automated reply, stating, “Legacy Media Lies.”
Elon Musk has debunked a report claiming his AI startup xAI had raised $15 billion from a funding round. Reports of the alleged funding round were initially reported by CNBC, which cited sources reportedly familiar with the matter.
CNBC’s report
The CNBC story cited unnamed sources that claimed that the new capital injection would help fund GPUs that xAI needs to train its large language model, Grok. The news outlet noted that following the funding round, xAI was valued at $200 billion.
Artificial intelligence startups have been raising funds from investors as of late. OpenAI raised $6.6 billion in October, valuing the startup at a staggering $500 billion. Reuters also reported last month that OpenAI was preparing for an IPO with a valuation of $1 trillion. Elon Musk’s xAI is looking to catch up and disrupt OpenAI, as well as its large language model, ChatGPT, which has become ubiquitous.
Elon Musk and xAI’s responses
In his response on X, Elon Musk simply stated that the CNBC story was “false.” He did not, however, explain if the whole premise of the publication’s article was fallacious, or if only parts of it were inaccurate.
Amusingly enough, xAI also issued a response when asked about the matter by Reuters, which also reported on the story. The artificial intelligence startup responded with what appeared to be an automated reply, which read, “Legacy Media Lies.”
xAI, founded in July 2023 as an alternative to OpenAI and Anthropic, has aggressively built out infrastructure to support its flagship products, including Grok and its recently launched Grokipedia platform. The company is developing its Colossus supercomputer in Memphis, which is heralded as one of the world’s largest supercomputer clusters.

Tesla reportedly testing Apple CarPlay integration: report
Citing insiders reportedly familiar with the matter, Bloomberg News claimed that CarPlay is being trialed by the EV maker internally.
Tesla is reportedly testing Apple’s CarPlay software for its vehicles, marking a major shift after years of resisting the tech giant’s ecosystem.
Citing insiders reportedly familiar with the matter, Bloomberg News claimed that CarPlay is being trialed by the EV maker internally. The move could help Tesla gain more market share, as surveys have shown many buyers consider CarPlay as an essential feature when choosing a car.
Not the usual CarPlay experience
Bloomberg claimed that Tesla’s tests involve a rather unique way to integrate CarPlay. Instead of replacing the vehicle’s entire infotainment display, Tesla’s integration will reportedly feature a CarPlay window on the infotainment system. This limited approach will ensure that Tesla’s own software, such as Full Self-Driving’s visuals, remains dominant.
The feature is expected to support wireless connectivity as well, bringing Tesla in line with other luxury automakers that already offer CarPlay. While plans remain fluid and may change before public release, the publication’s sources claimed that the rollout could happen within months.
A change of heart
Tesla has been reluctant to grant Apple access to its in-car systems, partly due to Elon Musk’s past criticism of the tech giant’s App Store policies and its poaching of Tesla engineers during the failed Apple Car project. Tesla’s in-house software is also deemed by numerous owners as a superior option to CarPlay, thanks to its sleek design and rich feature set.
With Apple’s retreat from building cars and Elon Musk’s relationship with Apple for X and Grok, however, the CEO’s stance on the tech giant seems to be improving. Overall, Tesla’s potential CarPlay integration would likely be appreciated by owners, as a McKinsey & Co. survey last year found that roughly one-third of buyers considered the lack of such systems a deal-breaker.
