Tesla CEO Elon Musk has provided a response to Top Gear‘s recent test of the Porsche Taycan Turbo S and the Tesla Model S Performance. In a couple of posts on Twitter, Musk noted that the Model S performance figures posted by the motoring publications are incorrect, and that an upcoming over-the-air update will be released for the flagship sedan to give it an additional edge against the top-tier Taycan.

Top Gear‘s Taycan vs Model S comparison was pretty balanced for the most part, with the publication noting that the Tesla is more comfortable for hauling passengers on long trips due to its superior range and large interior space. That being said, Top Gear also included a quarter-mile drag race between the two all-electric sedans, which reportedly ended with the Model S posting a 0-60 mph time of 2.68 seconds, a 0-100 mph of 6.46 seconds, and a quarter-mile time of 11.08 seconds at 124.0 mph. 

These times, which were exactly identical to the results of a Model S P100D vs Mercedes AMG E63S drag race from 2017, as well as signs that Top Gear did not engage the Model S’ Launch Mode and full Ludicrous Plus Mode during its race with the Taycan Turbo S, were highlighted in a video by veteran drag racer and DragTimes host Brooks. According to the longtime drag racer, the figures posted by Top Gear were suspicious, to say the least, as it did not reflect the actual capabilities of a Model S performing at optimum capacity. 

Musk responded to this comparison, stating that the DragTimes host is indeed correct in his observations. Never one to stand down, Musk also stated that the Model S Performance will be receiving a peak power increase through an upcoming over-the-air update. The update should add 50 hp to the flagship Model S, which should allow the flagship sedan to outrun the Porsche Taycan Turbo S in a 0-60 mph and quarter-mile sprint. 

Elon Musk’s recent announcement provides a bit more detail to the upcoming OTA update that is being prepared for the Model S, X, and Model 3. The update was initially mentioned during the company’s third-quarter earnings call, with CEO Elon Musk and CTO Drew Baglino describing the upcoming improvements. 

“We’re also expecting there’s going to be an over-the-air improvement that will improve the power of the Model S, X, and 3. That’s, by the way coming in a few weeks. Should be in the order of 5% power improvement due to improved firmware,” Musk said. Baglino added that the improvements are possible as Tesla continues to learn “how to optimize the motor control in our products.”  

With Musk’s recent tweets, it appears that Tesla’s upcoming update will give the Model S Performance a 50 hp boost. That’s a 50 hp improvement that will be received by the all-electric sedan through a free over-the-air update. Once the update is fully rolled out, it would be very interesting to see how the Model S Performance stacks up against the Porsche Taycan Turbo S.

Tesla has one big financial question to answer for investors: Morgan Stanley

Published

In a new note to investors on Tuesday, Morgan Stanley analyst Andrew Percoco said that Tesla has one big financial question to answer for investors regarding its Robotaxi rollout, Full Self-Driving software, and Optimus.

Percoco said in the note that, for the most part, investors are still very positive about the direction the company is headed. However, there are some things the firm would like to see, and they have to do with financials.

Tesla (TSLA) Q2 2026 earnings results: miss on EPS, beat on revenue

Tesla bulls are more than convinced that the company’s Full Self-Driving software is proof it can develop physical AI. Financially, however, there are still some questions, especially on elevated spending, which CEO Elon Musk said would occur as the company works to roll out Robotaxi faster and continue developing its Optimus robot.

The latter two are where Tesla will have to prove progress to investors, as Percoco writes that both projects “will require clearer evidence that Robotaxi is scaling and more tangible Optimus proof points to support the ROI on elevated capex.”

Percoco said the second quarter earnings call did not change his long-term thesis of where Tesla is positioned in the AI race, which is out in front. However, there are concerns that weaker gross margins and higher R&D spend will stress financials, and that has “sharpened our (and investors’) focus on measurable progress across Robotaxi and Optimus.”

Additionally, Robotaxi still needs to be proven with more operation in existing cities while maintaining safety but improving how many rides it gives in any given time, he said. For Optimus, Percoco wrote that he is “still looking for evidence beyond commentary around SOP.”

Morgan Stanley put Percoco in charge of covering Tesla after long-time analyst Adam Jonas transitioned to the automotive side.

Currently, Morgan Stanley has a $415 price target on Tesla and a ‘Hold’ rating on the stock. It is trading at around $330 at the time of publication, which was 2:30 P.M. on the East Coast.

SpaceX AI investment gamble will make it a big winner, firm says

Published

SpaceX’s massive investment in AI will make it a big winner, Argus Research said after the company’s successful earnings call last week.

The firm also upgraded shares to a Buy from Hold and set a $160 price target.

SpaceX (NASDAQ: SPCX) is currently recovering from its heavy AI infrastructure investments, as it spent nearly $16 billion in Q2 alone. The company did this primarily by monetizing high-demand GPU compute capacity at a much faster pace than traditional data center economics would suggest.

Company CFO Bret Johnsen said that SpaceX would be able to pay back anything on new deployments within a year.

There are plenty of ways the company can do this:

Leasing excess compute capacity through contracts

SpaceX has already built Colossus and Colossus II, largely for its own model training. However, much of that capacity is already rented out to third parties. It already has major deals with Anthropic, Google, and Reflection AI. These partnerships are adding billions per month to SpaceX’s spreadsheet.

SpaceX is charging Anthropic massive money for its compute

High utilization driven by industry-wide scarcity

The demand for advanced AI training and inference capacity continues to exceed what is available for use. SpaceX can fill new racks quickly after they come online, so the capital deployed converts into revenue with minimal idle time.

Additionally, management and outside observers have described the new compute capital as behaving more like a cost-of-goods-sold than traditional multi-year capex, especially because of this rapid monetization pattern.

Capacity has already scaled from ~0.4 GW a year to 1.4 GW annually by the end of Q2. There are targets of more than 2 GW by year-end.

High incremental margins on the rental business once capacity is online

GPU cloud providers often operate at strong gross margins. SpaceX can monetize capacity that was already partially built or can be added efficiently. This means that incremental EBITDA margins on the rental revenue are usually high. This accelerates cash recovery relative to the gross capital outlay.

Parallel monetization of its own AI software and applications

Beyond pure infrastructure rental, SpaceX also generates revenue from Grok through subscriptions and usage, from X through ads, data, and other related services, enterprise APIs, and the planned integration of the Cursor coding tools acquisition.

These application layers ride on the same compute infrastructure and provide additional high-margin streams that could offset build-out costs. AI-segment revenue overall rose sharply to about $2.6 billion in Q2, according to Motley Fool. This was driven primarily by the infrastructure contracts, but the software side is also partially responsible.

Efficient, large-scale deployment and vertical integration advantages

SpaceX has emphasized the rapid construction of power and cooling infrastructure and favorable cost-per-megawatt economics relative to industry benchmarks in some disclosures.

Combined with its ability to scale capacity aggressively and the fact that many contracts start generating revenue within months of capacity coming online, the effective payback compresses dramatically compared with more conventional multi-year data-center projects.

SpaceX’s dominant near-term recovery path will turn the AI clusters into a hyperscale-style compute rental business for other leading AI companies while still using a portion for internal models.

Tesla headlights cause recall of over 20,000 Model 3 and Model Y

Published

on

Tesla headlights have caused a recall of over 20,000 of the company’s two most popular vehicles, the Model 3 and Model Y, due to the low-beam bulb exceeding the maximum allowed intensity according to federal standards.

Tesla initiated the recall with the National Highway Traffic Safety Administration (NHTSA) this morning, stating that the low-beam output “exceeds the maximum allowed intensity in the outer upper-right and outer upper-left areas of the 10U and 90U zone, as prescribed in FMVSS No. 108.”

Tesla sourced the impacted headlights from Marelli Automotive Lighting, a Mexico-based company. The recall impacts 2020-2023 Model Y vehicles and 2017-2023 Model 3 vehicles. It is estimated that every VIN in this recall is impacted by the defect.

Typically, Tesla would remedy recalls of this nature through an Over-the-Air software update, which has been a major focus of criticism by the company and its supporters because the NHTSA still refers to it as a “recall,” even though it requires no action by the vehicle owner. The fix is shipped over the internet and downloaded to the car.

However, there appears to be a potentially different solution for this problem. Tesla has not developed a remedy for this issue, so it could potentially be on the way. The big issue appears to be the fact that these recalled lamps are out of production, and this is an old body style for both vehicles. The headlights and front-end designs are completely different.

Tesla switched to another supplier when the affected headlight design was discontinued. It plans to begin notifying owners of their remedy options by September 15.

Tesla filed a petition protesting the recall to fix the vehicles’ headlight issue, but the NHTSA denied it. Now, Tesla will come up with a solution to fix it.
