It is, perhaps, the biggest question many prospective hand-wringing owners of the Model S wrestle with – should I get the Tesla Model S P85 or stick to the Standard version?

After all, once you’ve talked yourself up the first $10k from a 60kwh to an 85kwh battery, what’s another $12K or so for the Performance version?

And if you don’t pay for the upgrade to the more powerful drivetrain, WILL YOU REGRET IT LATER?! Want to know the bottom line? My journey to owning the Model S led me to ask the following questions: Will you regularly drive over 180 miles/day? Will you use the Tesla for a road trip car? If the answer to both those questions is “No”, get the 60 kWh. Period. Done.

The 60 has comparable real world performance to the 85 and reportedly feels even more spirited because of less battery weight (though ballasted to match an 85, the ballast is apparently located differently somehow, according to reports from people who have driven both). The 60 is a superb in-town commuter car or medium distance tourer (with destination charging). If either those questions are answered with a “Yes”, get the 85kWh. By the time you pay the extra $2k to enable the Supercharging option on a 60 you’ve already started toward an 85 anyway. Like the evil dojo master in Karate Kid said, “Finish him!” Get an 85. Now don’t go crazy right to the P85+, let’s look at the upper extreme first.

The P85+ is apparently designed solely for the purpose of destroying tires – rear tires – every 5,000 miles or less. Unless you’re coming from a high performance car or plan to enjoy track days, fuggeddaboutit. It’s basically an even more expensive version of the P85 with staggered tires and other suspension tricks. Real world, this is overkill and more about badge ego than useful value (for the vast majority of non-professional racing drivers).

Speaking of real world, the performance difference for the P85 and the S85 exists primarily in one place: 0-30mph. That’s it. From 30mph and up they are virtually identical and both will silently roar around slower traffic with equal capability. Originally the Tesla Model S P85 upgrade only came with some other standard features that are a mixed bag (to me). Thankfully Tesla has decided to allow buyers the option of upgrading only the drivetrain. Still, that presents some problems. A P85 with the 19″ wheels just overwhelms them. Remember the only performance advantage it has is 0-30mph and that requires grip to actually enjoy it. For a variety of reasons (but chief among them rolling resistance and wind resistance) Tesla’s tires are taller rather than wider to increase their contact patch. A traditional sports sedan would get wider tires to increase grip but the Model S gets taller tires… ergo, a P85 on 19s just bounces off the traction control constantly. In a sunny climate that might not happen as often but here in pothole country you’ll get clunks and shudders from way back there at the wheels all the time as the traction control tries to reign in your lunacy. My friend Jake and I had several days with a silver loaner (read more about it here) and it was fun but also frustrating.

Unfortunately, if you’re living anywhere with four seasons you are NOT going to want to alleviate the traction problem by getting 21″ wheels. We have potholes. LOTS of them. BIG ones. And bridges with expansion joints that will turn those wheels into ovals. You know how when you go to the grocery store you always get a cart with that annoying wobbly wheel? Would you like to buy one for $90-100K? I didn’t think so. Speaking of expenses, many P85 owners report higher than average tire wear (regardless of wheel size).

I don’t know of a true head-to-head drag race video of all THREE versions of the Model S (60/85/P85)– amazed no one has done it yet– but the video above is very recent and posts a time faster than the Tesla website does. You can read more opinions on that video HERE.

Another recent video does offer a head-to-head of a standard Tesla Model S P85 vs S85 and you can see that after the first 30 feet or so, the S85 and the P85 match stride-for-stride. In fact, at the end of the 1/4 the trap speed on the standard 85 is actually higher. Skip ahead 26 seconds to catch the Tesla family feud.

One long-time P85 owner asserts the difference in launch speed really only exists at higher states of charge. As a result, maintaining that performance edge over the S85 requires more frequent and fuller charges of the main pack, potentially increasing long-term degradation. Ironically, the only times you really should charge the pack up to higher levels (for distance), you wouldn’t want to enjoy the harder launches because it would adversely affect your range.

So the S85 is a tad slower off the line. No one but a P85 owner is ever going to know that. And, frankly, the power delivery at launch is a lot smoother. The P85 is pretty brutal. Oh, it’s damn impressive– but it’s also jarring. I like the slightly tapered building on of WHOOSH that I get from the S85. I think it keeps my wife from realizing how often I’m toying with the other cars around us. James Bond, after all, wears a suit… not a karategi. <— brought that back to Karate Kid nicely, didn’t I? I have no idea why either.

Clearly I could go on and on about my configuration thought processes– and how they’ve evolved since taking delivery– but that’s a topic for another time.

Tesla is upgrading airbag safety through a crazy software update

“This upgrade builds upon your vehicle’s superior crash protection by now using Tesla Vision to help offer some of the most cutting-edge airbag performance in the event of a frontal crash.”

Tesla is upgrading airbag safety through a crazy software update, which will utilize the company’s vision-first approach to enable better protection in the event of an accident.

Over the years, Tesla has gained an incredible reputation for prioritizing safety in its vehicles, with crash test ratings at the forefront of its engineers’ minds.

This has led to Tesla gaining numerous five-star safety ratings and awards related to safety. It is not just a statistical thing, either. In the real world, we’ve seen Teslas demonstrate some impressive examples of crash safety.

Everything from that glass roof not caving in when a tree falls on it to a Model Y surviving a drive off a cliff has been recorded.

However, Tesla is always looking to improve safety, and unlike most companies, it does not need a physical hardware update to do so. It can enhance features such as crash response and airbag performance through Over-the-Air software updates, which download automatically to the vehicle.

In Tesla’s 2025.32 Software Update, the company is rolling out a Frontal Airbag System Enhancement, which aims to use Tesla Vision, the company’s camera-based approach to self-driving, to keep occupants safe.

The release notes state (via NotaTeslaApp):

“This upgrade builds upon your vehicle’s superior crash protection by now using Tesla Vision to help offer some of the most cutting-edge airbag performance in the event of a frontal crash. Building on top of regulatory and industry crash testing, this release enables front airbags to begin to inflate and restrain occupants earlier, in a way that only Tesla’s integrated systems are capable of doing, making your car safer over time.”

The use of cameras to predict a better time to restrain occupants with seatbelts and inflate airbags prior to a collision is a fantastic way to prevent injuries and limit harm done to those in the vehicle.

The feature is currently limited to the Model Y.

Elon Musk says this Tesla project will make up vast majority of company value

“~80% of Tesla’s value will be Optimus,” Musk said.

Tesla CEO Elon Musk has not shied away from the idea that the company’s value is not reliant on its performance as an automaker.

That idea is even more prudent in today’s landscape than ever, especially as Tesla leans more on its prowess as an AI, autonomy, and robotics company rather than one that just makes electric cars.

Musk solidified that point on Monday, as he revealed that he believes the vast majority of Tesla’s valuation will rely on a project that the company has been developing for several years.

The CEO has long discussed how robotics will revolutionize the labor landscape in factories, households, and other workplaces.

He believes Optimus, as it is rolled out in the coming years, will truly take over as the main contributor to Tesla’s valuation, being worth about 80 percent of the company’s total market cap:

Those are the biggest factors.
~80% of Tesla’s value will be Optimus.
— Elon Musk (@elonmusk) September 1, 2025

This is a point Musk has previously discussed, but he has never listed a specific number in terms of what Optimus could mean to Tesla. In the past, he’s mentioned Optimus’s ability to generate long-term revenue potential, its value to the company, and its impact on the market overall.

Musk has said Optimus has the potential to be worth over $10 trillion in revenue:

“It’s one of those things where I think long term, Optimus will be — Optimus has the potential to be north of $10 trillion in revenue, like it’s really bananas. So, that, you can obviously afford a lot of training compute in that situation. In fact, even $500 billion training compute in that situation would be quite a good deal.”

Optimus has been a main point of discussion amongst analysts who cover the company. Piper Sandler recently released a note that said “Optimus should be moving/staging parts within Tesla’s facilities” by this time next year.

Analysts also said that Optimus could be a major benefit for companies to bring in to handle tedious tasks in manufacturing settings. If it is able to work 18-hour shifts, the firm believes Tesla could price it at $100,000 per unit.

Other firms, like Morgan Stanley, have said Tesla could replace its own staff by 10 percent with Optimus, saving the company $2.5 billion.

Tesla appears to be mulling a Cyber SUV design

In a new video titled “Sustainable Abundance,” Tesla was showing the Cybercab clay models being autonomously molded. In the back, there are very clearly several models of a Cybertruck-inspired SUV:

Tesla appears to be mulling a Cyber SUV design, which would encapsulate the stainless steel exoskeleton of the Cybertruck but with elements of an SUV.

The company has been hearing from consumers and fans for some time that it is in need of a full-size SUV in its lineup.

Tesla is missing one type of vehicle in its lineup and fans want it fast

The Model X is more compact than what people are looking for, and although the company has said its focus for some time would be on developing affordable models and the Cybercab, which only enables two-passenger travel, it appears that it may be considering other options.

This would not be the first time Tesla has placed projects it is developing in the back of a promotional video, as it did something similar when it was unveiling the improvements it made to the new Model Y earlier this year.

It appeared to show two new body styles sitting in the back under car covers:

There are two things that could prevent this from becoming a future, developed product that reaches the market. One of them seems to be a definitive no, but Tesla’s plans could certainly change, especially given the strong push from fans for this type of vehicle.

Tesla said it wouldn’t build a Stainless Steel exoskeleton vehicle again

Tesla said in its Q4 2024 Shareholder Deck that Cybertruck’s stainless steel exoskeleton would not be used in future vehicles in the top line:

This seems like a definitive no in terms of developing an SUV based on Cybertruck’s aesthetics. However, that could always change.

Tesla’s main focus in autonomy currently

Developing an SUV of this size has been previously dismissed by Tesla, as its focus is on autonomy, AI, and robotics. However, it will still need to develop attractive and useful vehicles that address a large market, and the United States has a strong affinity for SUVs and crossovers.

It seems totally feasible that Tesla could bring this type of vehicle to market to appease the many fans who have called for the company to build it. Tesla has not committed to anything at this point, which is the most important thing to remember.
