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 launches TERAFAB: The $25B Tesla-SpaceXAI chip factory that will rewire the AI industry
Tesla, SpaceX, and xAI unveiled TERAFAB, a $25B chip factory targeting one terawatt of AI compute annually.
Elon Musk took the stage over the weekend at the defunct Seaholm Power Plant in Austin, Texas, to officially unveil TERAFAB, a $20-25 billion joint venture between Tesla, SpaceX, and xAI that he described as “the most epic chip building exercise in history by far.” The announcement marks the most ambitious infrastructure bet Musk has made since Gigafactory 1 in Sparks, Nevada, and it fuses three of his companies into a single, vertically integrated AI hardware machine for the first time.
TERAFAB is designed to consolidate every stage of semiconductor production under one roof, including chip design, lithography, fabrication, memory production, advanced packaging, and testing. At full capacity, the facility would scale to roughly 70% of the global output from the current world’s largest semiconductor foundry from Taiwan Semiconductor Manufacturing Company (TSMC).
Elon Musk’s stated goal is one terawatt of computing power annually, split between Tesla’s AI5 inference chips for vehicles and Optimus robots, and D3 chips built specifically for SpaceXAI’s orbital satellite constellation.
Tesla Terafab set for launch: Inside the $20B AI chip factory that will reshape the auto industry
The logic behind the merger of these three entities is rooted in a supply chain crisis Musk has been signaling for over a year. At Tesla’s Q4 2025 earnings call, he warned investors that external chip capacity from TSMC, Samsung, and Micron would hit a ceiling within three to four years. “We’re very grateful to our existing supply chain, to Samsung, TSMC, Micron and others,” Musk acknowledged at the Terafab event, “but there’s a maximum rate at which they’re comfortable expanding.” Building in-house was, in his framing, not a strategic option, but a necessity.
The space angle is where the announcement becomes genuinely unprecedented. Musk said 80% of Terafab’s compute output would be directed toward space-based orbital AI satellites, arguing that solar irradiance in space is roughly 5x greater than at Earth’s surface, and that heat rejection in vacuum makes thermal scaling viable. This directly feeds the SpaceXAI vision, which is betting that within two to three years, running AI workloads in orbit will be cheaper than doing so on the ground. The satellites, powered by constant solar energy, would effectively turn low Earth orbit into the world’s largest data center.
Will Tesla join the fold? Predicting a triple merger with SpaceX and xAI
Historically, this announcement threads together every major Musk initiative of the past two years: the xAI-SpaceX merger, Tesla’s $2.9 billion solar equipment talks with Chinese suppliers, the 100 GW domestic solar manufacturing push, the Optimus humanoid robot program, and Starship’s development. TERAFAB is the capstone that ties them into a single coherent architecture — chips made on Earth, launched by SpaceX, powered by Tesla solar, run by xAI, and ultimately extended to the Moon.
“I want us to live long enough to see the mass driver on the moon, because that’s going to be incredibly epic,”Musk said during the presentation.

Rolls-Royce makes shocking move on its EV future
When Rolls-Royce unveiled its first all-electric model, the Spectre, in 2022, former CEO Torsten Müller-Ötvös declared the brand would cease production of internal combustion engine vehicles by the end of the decade.
Rolls-Royce made a shocking move on its EV future after planning to go all-electric by the end of the decade. Now, the company is tempering its expectations for electric vehicles, and its CEO is aiming to lean on its legacy of high-powered combustion engines to lead it into the future.
In a significant reversal, Rolls-Royce Motor Cars has scrapped its ambitious plan to become an all-electric manufacturer by 2030. The luxury British marque announced the decision amid sustained customer demand for traditional combustion engines and shifting regulatory landscapes.
When Rolls-Royce unveiled its first all-electric model, the Spectre, in 2022, former CEO Torsten Müller-Ötvös declared the brand would cease production of internal combustion engine vehicles by the end of the decade.
The move aligned with the industry’s broader push toward electrification, promising silent, effortless power befitting the “Rolls-Royce of cars.”
However, new CEO Chris Brownridge, who assumed the role in late 2023, has reversed course. “We can respond to our client demand … we build what is ordered,” Brownridge stated.
The company will continue offering its iconic V12 engines, which remain a cornerstone of its heritage and appeal to discerning buyers who appreciate the distinctive sound and character. He noted the original pledge was “right at the time,” but “the legislation has changed.”
While not abandoning electric vehicles entirely, the Spectre remains in production, with an electric Cullinan option forthcoming; the decision marks the end of a strict all-EV timeline. Relaxed emissions regulations and slowing EV demand, evidenced by a 47 percent drop in Spectre sales to 1,002 units in 2025, forced the reconsideration.
It was a sign that perhaps Rolls-Royce owners were not inclined to believe that the company’s all-EV future was the right move.
Rolls-Royce joins a growing roster of automakers reevaluating aggressive electrification targets.
Fellow luxury brand Bentley has pushed its full electrification from 2030 to 2035, while continuing to offer hybrids and ICE models. Mercedes-Benz walked back its 2030 all-EV goal, now aiming for about 50% electrified sales while keeping combustion engines into the 2030s. Porsche has abandoned its 80% EV sales target by 2030, delaying models and extending hybrids.
Mainstream giants are following suit. Honda canceled its U.S. EV plans, including the 0-Series and Acura RSX, facing a $15.7 billion hit as it doubles down on hybrids. Ford and General Motors have incurred tens of billions in writedowns, canceling models and pivoting to hybrids amid an industry total exceeding $70 billion in charges.
This trend reflects a pragmatic shift driven by infrastructure gaps, consumer preferences, and policy changes. In the ultra-luxury segment, where emotional connection reigns, automakers are prioritizing flexibility over rigid deadlines, ensuring brands like Rolls-Royce evolve without alienating their core clientele.

This optimistic timeline for tape-out—the stage where chip design is finalized before manufacturing—signals Tesla’s push to rapidly advance its silicon capabilities.
The announcement builds on progress with the predecessor AI5. Earlier in January, Musk announced that the AI5 design was “in good shape” and “almost done,” describing it as an “existential” project for the company that demanded his personal attention on weekends.
He characterized AI5 as roughly equivalent to Nvidia’s Hopper class performance in a single system-on-chip (SoC) and Blackwell-level as a dual configuration, but at significantly lower cost and power usage.
Elon Musk is setting high expectations for Tesla AI5 and AI6 chips
Musk highlighted that AI5 “will punch far above its weight” thanks to Tesla’s co-designed AI software and hardware stack, making maximal use of every circuit. While capable of data center training tasks, it is primarily optimized for edge computing in Optimus robots and Robotaxi vehicles.
For AI6, Musk envisions substantial gains. “In the same half reticle and same process node, we think a single AI6 chip has the potential to match a dual SoC AI5,” he explained.
The company is targeting ambitious nine-month development cycles for future chips, allowing rapid iteration to AI7, AI8, and beyond. AI5/AI6 engineering remains Musk’s top time allocation at Tesla, with the CEO calling AI5 “good” and AI6 “great.”
Samsung is expected to manufacture the AI6 chips, following deals worth billions, while AI5 will leverage TSMC and Samsung production. These chips will form the backbone of Tesla’s Full Self-Driving system, enabling safer and more capable autonomy, alongside powering dexterous movements in Optimus bots and efficient inference in expanding data centers.

Musk has also restarted work on the Dojo 3 supercomputer project now that AI5 is progressing. Long-term plans include in-house manufacturing via the Terafab facility.
By accelerating chip development with AI tools, Tesla aims to reduce dependence on third-party GPUs and deliver high-performance, energy-efficient solutions tailored to its ecosystem. Success with AI6 could mark a major milestone in Tesla’s journey toward full autonomy and robotics leadership, though timelines remain subject to manufacturing realities.
