Should I Buy the Tesla Model S P85 or Standard 85kWh?
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 adds new feature that will be great for crowded parking situations
This is the most recent iteration of the app and was priming owners for the slowly-released Holiday Update.
Tesla has added a new feature that will be great for crowded parking lots, congested parking garages, or other confusing times when you cannot seem to pinpoint where your car went.
Tesla has added a new Vehicle Locator feature to the Tesla App with App Update v4.51.5.
This is the most recent iteration of the app and was priming owners for the slowly-released Holiday Update.
While there are several new features, which we will reveal later in this article, perhaps one of the coolest is that of the Vehicle Locator, which will now point you in the direction of your car using a directional arrow on the home screen. This is similar to what Apple uses to find devices:
Interesting. The location arrow in the Tesla app now points to your car when you’re nearby. pic.twitter.com/b0yjmwwzxN

In real time, the arrow gives an accurate depiction of which direction you should walk in to find your car. This seems extremely helpful in large parking lots or unfamiliar shopping centers.
Getting to your car after a sporting event is an event all in itself; this feature will undoubtedly help with it:
The nice little touch that Tesla have put in the app – continuous tracking of your vehicle location relative to you.
There’s people reporting dizziness testing this.
To those I say… try spinning your phone instead. 😉 pic.twitter.com/BAYmJ3mzzD

Tesla’s previous app versions revealed the address at which you could locate your car, which was great if you parked on the street in a city setting. It was also possible to use the map within the app to locate your car.
However, this new feature gives a more definitive location for your car and helps with the navigation to it, instead of potentially walking randomly.
It also reveals the distance you are from your car, which is a big plus.
Along with this new addition, Tesla added Photobooth features, Dog Mode Live Activity, Custom Wraps and Tints for Colorizer, and Dashcam Clip details.

All in all, this App update was pretty robust.
Tesla CEO Elon Musk shaded Waymo in a post on X on Wednesday, stating the company “never really had a chance” and that it “will be obvious in hindsight.”
Tesla and Waymo are the two primary contributors to the self-driving efforts in the United States, with both operating driverless ride-hailing services in the country. Tesla does have a Safety Monitor present in its vehicles in Austin, Texas, and someone in the driver’s seat in its Bay Area operation.
Musk says the Austin operation will be completely void of any Safety Monitors by the end of the year.

With the two companies being the main members of the driverless movement in the U.S., there is certainly a rivalry. The two have sparred back and forth with their geofences, or service areas, in both Austin and the Bay Area.
While that is a metric for comparison now, ultimately, it will not matter in the coming years, as the two companies will likely operate in a similar fashion.
Waymo has geared its business toward larger cities, and Tesla has said that its self-driving efforts will expand to every single one of its vehicles in any location globally. This is where the true difference between the two lies, along with the fact that Tesla uses its own vehicles, while Waymo has several models in its lineup from different manufacturers.
The two also have different ideas on how to solve self-driving, as Tesla uses a vision-only approach. Waymo relies on several things, including LiDAR, which Musk once called “a fool’s errand.”
This is where Tesla sets itself apart from the competition, and Musk highlighted the company’s position against Waymo.
Jeff Dean, the Chief Scientist for Google DeepMind, said on X:
“I don’t think Tesla has anywhere near the volume of rider-only autonomous miles that Waymo has (96M for Waymo, as of today). The safety data is quite compelling for Waymo, as well.”
Musk replied:
“Waymo never really had a chance against Tesla. This will be obvious in hindsight.”
Waymo never really had a chance against Tesla. This will be obvious in hindsight.

Tesla stands to have a much larger fleet of vehicles in the coming years if it chooses to activate Robotaxi services with all passenger vehicles. A simple Over-the-Air update will activate this capability, while Waymo would likely be confined to the vehicles it commissions as Robotaxis.

Tesla supplier Samsung preps for AI5 production with latest move
According to a new report from Sedaily, Samsung is accelerating its preparation for U.S. production of the AI5 chips by hiring veteran engineers for its Customer Engineering team.
Tesla supplier Samsung is preparing to manufacture the AI5 chip, which will launch the company’s self-driving efforts even further, with its latest move.
According to a new report from Sedaily, Samsung is accelerating its preparation for U.S. production of the AI5 chips by hiring veteran engineers for its Customer Engineering team, which will help resolve complex foundry challenges, stabilize production and yields, and ensure manufacturing goes smoothly for the new project.
The hiring push signals that Tesla’s AI5 project is moving forward quickly at Samsung, which was one of two suppliers to win a contract order from the world’s leading EV maker.

TSMC is the other. TSMC is using its 3nm process, reportedly, while Samsung will do a 2nm as a litmus test for the process.
The different versions are due to the fact that “they translate designs to physical form differently,” CEO Elon Musk said recently. The goal is for the two to operate identically, obviously, which is a challenge.
Some might remember Apple’s A9 “Chipgate” saga, which found that the chips differed in performance because of different manufacturers.
The AI5 chip is Tesla’s next-generation hardware chip for its self-driving program, but it will also contribute to the Optimus program and other AI-driven features in both vehicles and other projects. Currently, Tesla utilizes AI4, formerly known as HW4 or Hardware 4, in its vehicles.
Tesla teases new AI5 chip that will revolutionize self-driving
AI5 is specialized for use by Tesla as it will work in conjunction with the company’s Neural Networks, focusing on real-time inference to make safe and logical decisions during operation.
Musk said it was an “amazing design” and an “immense jump” from Tesla’s current AI4 chip. It will be roughly 40 times faster, and have 8 times the raw compute, with 9 times the memory capacity. It is also expected to be three times as efficient per watt as AI4.
“We’re going to focus TSMC and Samsung, initially, on AI5. The AI5 chip, design by Tesla, it’s an amazing design. I’ve spent almost every weekend for the last few months with the chip team working on AI5.”
It will be 40x better than the AI4 chip, Musk says.

AI5 will make its way into “maybe a small number of units” next year, Musk confirmed. However, it will not make its way to high-volume production until 2027. AI5 is not the last step, either, as Musk has already confirmed AI6 would likely enter production in mid-2028.
