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. If you haven’t already read about my “Journey to Tesla” then check it out for some insights into how I got this car in my driveway and how you can too. It starts by clicking RIGHT HERE.

Elon Musk
Space finally faced the people living next to its next Terafab mega-project
SpaceX confirmed Terafab’s Grimes County site is locked in, with construction starting within months.
SpaceX and Terafab representatives sat across from Grimes County residents for the first time on Wednesday, telling a packed Commissioners Court room that the $55 billion chip manufacturing project is now a done deal at the Gibbons Creek Reservoir site.
The meeting followed a $10 million check SpaceX sent the county earlier this week, satisfying a payment deadline built into the tax abatement agreement both sides signed in June. Elon Musk shared a post on X confirming the payment, and County Judge Joe Fauth told the San Antonio Express-News his office deposited the check after it beat its deadline.
Wednesday’s session, first reported by KBTX, moved the project from paperwork to construction. Terafab representative Riley Trennell told residents the JETI tax break agreements with Iola ISD and Anderson-Shiro CISD are signed and active, and that civil work and foundation prep are starting almost immediately. Renderings of the facility could be released within days, he said, with construction beginning within months.
Elon Musk launches TERAFAB: The $25B Tesla-SpaceXAI chip factory that will rewire the AI industry
Musk first announced Terafab in March as a joint venture between Tesla, SpaceX and xAI aimed at producing over a terawatt of AI compute annually, an amount that dwarfs the roughly 20 gigawatts the entire global chip industry produces today. Intel joined as a manufacturing partner in April. Musk has said the project needed its own day in the spotlight rather than being squeezed into an earnings call, and for months the Grimes County site remained unconfirmed even as reporting pointed there.
SpaceX attorney Buck Brannon used Wednesday’s meeting to note that the company’s abatement is roughly 78 percent, not the 100 percent some earlier reports suggested. In exchange, SpaceX will pay Grimes County a fixed $20 million a year for 35 years, a total of $710 million, which Brannon said exceeds the $14 million Tesla paid Travis County in 2025.
SpaceX also addressed environmental concerns that have followed the project since Musk’s Terafab partnership with Intel was announced. Representatives said Terafab will not raise electric bills for other ratepayers, will not deplete local water supplies and will not draw down the Navasota River. SpaceX confirmed it owns the Navasota River pumping station, which it plans to use to divert stormwater into the Gibbons Creek Reservoir, and said it will build its own natural gas plants to power the facility rather than pulling from the ERCOT grid.

Grimes County commissioners also approved an addendum letting county employees use ten approved AI chatbots for work, including Grok.
Elon Musk has declared that SpaceX has effectively solved one of Starship’s most persistent engineering challenges: the reliability of its heat shield tiles.
During the company’s first-ever Earnings Call, the SpaceX CEO stated:
“I don’t want to jinx it or anything, but I think I would call the heat shield problem solved at this point. All indications from data and visual inspection is we have solved it. That doesn’t mean we won’t make improvements, but we do not see any technical obstacles to achieving rapid reusability at this point.”
Starship’s heat shield consists of roughly 18,000 hexagonal ceramic tiles covering the windward side of the upper stage. These tiles form the thermal protection system that shields the vehicle’s stainless-steel structure from the extreme heat of atmospheric reentry.
Elon says he believes the heat shield problem with Starship is currently solved.

During descent, atmospheric friction generates temperatures exceeding several thousand degrees Celsius and creates plasma flows capable of melting unprotected metal. The tiles absorb, radiate, and insulate against this energy, allowing the vehicle to survive and potentially fly again. Without a durable heat shield, full and rapid reusability, the cornerstone of Starship’s design for frequent launches, satellite deployments, and deep-space missions, would remain impossible.
The tiles have long been a source of difficulty. On earlier test flights, a significant number of tiles detached during ascent due to vibration, aerodynamic loads, and imperfect attachment methods using pins and adhesives. Gaps between tiles allowed hot plasma to infiltrate, causing secondary damage and hot spots on the underlying structure.
These issues echoed challenges faced by NASA’s Space Shuttle, whose ceramic tiles required extensive, labor-intensive inspections and replacements between missions, preventing rapid turnaround. SpaceX has iteratively improved materials, standardized tile shapes, refined attachment techniques, added secondary ablative layers, and tested sealing methods such as “crunch wrap” felt to close gaps.
Progress was visible across Flights 10–12, with steadily better tile retention, yet questions remained about whether the system could support the minimal-refurbishment goal of rapid reuse.
Flight 13 on July 24 provided the decisive evidence. Ship 40 flew a deliberately more demanding profile with higher dynamic pressure to stress the heat shield beyond typical operational loads. It successfully deployed 20 operational Starlink V3 satellites, the first such payload on a Starship mission, performed an in-space Raptor engine relight, and executed a controlled reentry.

Cameras on six of the satellites and onboard sensors captured extensive imagery and data of the shield throughout the flight. The ship then achieved its softest splashdown to date in the Indian Ocean, remaining intact and floating rather than breaking apart or exploding as on prior missions. This allowed drone inspections and continuous telemetry of the heat shield in near-real time.

Post-flight analysis showed the majority of tiles remaining attached with only minor damage and limited plasma streaking at seams. Musk noted that the mission delivered “all the heat shield data we needed and then some.” Combined with visual inspections, these results underpinned his subsequent assessment that the core technical barriers to rapid reusability have been cleared. While refinements will continue, Flight 13 marked a pivotal step toward Starship’s operational future.
SpaceX COO Gwynne Shotwell outlined ambitious plans for Starlink Mobile during the company’s August 4 Earnings call, signaling a direct challenge to U.S. wireless giants like AT&T, T-Mobile, and Verizon.
Shotwell noted that the three companies generate roughly $600 billion in combined annual revenue. “I anticipate us to be able to acquire quite a few of their customers because I think our service will be better,” she said. “We will eliminate dead zones leveraging the satellites in orbit. It will be better during any natural disaster… I’m quite excited about Starlink Mobile.”

SpaceX intends to combine its satellite constellation with terrestrial infrastructure. The company has acquired about 65 MHz of spectrum from EchoStar and plans to deploy next-generation Starlink Mobile satellites in 2027, with upgraded service targeted for the end of that year.
Shotwell described the enhanced network, leveraging more satellites and spectrum, as potentially “100 times better” than the current direct-to-cell offering, which already supports basic texting and app-based voice/video in coverage gaps through partnerships. She also indicated plans for low-cost cellular base stations that could integrate with existing Starlink dishes, creating a hybrid system for broader capacity in urban, suburban, and rural areas.

For the general public, Starlink Mobile promises significant advantages. Satellite connectivity can fill gaps where traditional cell towers fail, delivering service in remote locations, mountains, or during outages caused by storms, wildfires, or infrastructure damage—conditions in which ground networks often collapse.
Users could enjoy more consistent coverage without relying solely on dense tower builds, potentially at competitive prices as SpaceX scales. The hybrid approach aims to support full mobile services, including higher-speed data, while working with unmodified smartphones over time.
These developments revive long-standing but unfounded rumors of a Musk-developed “Tesla phone.” Speculative claims of a “Pi Phone” or similar device with built-in Starlink connectivity have circulated for years on social media, often featuring fabricated images and details. Elon Musk has repeatedly denied any such plans, stating Tesla has no intention of entering the smartphone market unless forced by extreme circumstances with app stores.
No official product, filings, or development announcements have ever materialized; the rumors remain hoaxes.
The announcement quickly pressured telecom stocks. Shares of AT&T, Verizon, and T-Mobile fell between roughly 2 and 4 percent in after-hours and premarket trading as investors weighed the competitive threat from a hybrid satellite-terrestrial network.
While execution challenges remain—spectrum deployment, infrastructure rollout, and regulatory hurdles—Shotwell’s remarks mark SpaceX’s clearest signal yet of entering the consumer mobile market as a full competitor.
