Should I Buy the Tesla Model S P85 or Standard 85kWh?

Published

Brown-Grey-Model-S-Supercharger

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.

Model-S-MotorThe 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).

Silver-Model-S-PittsburghSpeaking 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.

Investor's Corner

Tesla’s flying Roadster just revealed something bigger than the car

Analysts say the Roadster demo puts a Tesla and SpaceX merger back on the table.

The Roadster unveiling near Waco ended Thursday night, and by Friday morning much of the investor reaction had less to do with the car than with who owns the rocket technology inside it.

Wedbush analyst Dan Ives said the event “puts the Tesla/SpaceX relationship on the table in a tangible way,” pointing to the propulsion, pressure vessel and control hardware sitting on a Tesla product. Gene Munster of Deepwater Asset Management called the demo “a ridiculous display of engineering” with “no commercial value” beyond embarrassing traditional automakers, though he said it showed Musk wants the two companies together.

The more specific forecast came a day earlier from Barclays. Analyst Dan Levy told clients a deal could be announced before Tesla’s annual meeting, which must happen by December 6, and that an announcement in late October or early November could make shareholder approval harder. Barclays expects SpaceX to be the buyer in an all stock deal, with Tesla holders receiving SpaceX shares at a premium, based on market values of roughly $2.1 trillion for SpaceX and $1.5 trillion for Tesla. If nothing lands around the meeting, the bank still sees an announcement within 6 to 12 months.

The Roadster demo just added more weight to merger speculations. Tesla’s demo used cold gas thrusters and pressure tanks of the kind SpaceX uses on Falcon 9, and Musk described the car as a collaboration between Tesla and SpaceX engineers, as we mentioned in our breakdown of the three Roadster configurations.


Musk has not publicly addressed a deal since the event, as far as we have seen. His most direct answer remains the one he gave at the All In Summit, when he said that with so much collaboration, “who can imagine what action one might take” without ruling anything out. Ives has held to a 2027 timeline since his March note, and Musk pushed back on the China piece of the speculation when ARK floated a year end announcement in August.

The next test is Tesla’s third quarter earnings call on October 21. However, we recall in July that Musk told analysts, “we can’t talk about combining companies and that kind of thing on an earnings call,” so a clear answer wouldn’t be expected.

How Tesla’s Roadster fan system and thrusters are built to dominate the corners

Tesla’s Roadster uses fans, active wings and cold gas thrusters to create grip at any speed.

Tesla’s new Roadster is best known for flipping through the air in Texas, but the technology that matters most for a race track is the stuff that keeps it on the ground. Tesla’s Roadster page describes a multi-mode fan and ground sealing system that acts as a downforce generator, pulling air out from beneath the car. Tesla says it provides enough suction to hold the vehicle upside down, even when stationary.

That is the key difference from the wings and diffusers on a normal supercar. Conventional aero only makes downforce when the car is moving, and it grows with speed, so a car has the least grip in the slow corners and under hard braking. A fan system makes downforce at any speed. Tesla’s patent, which we covered last year, describes fans and deployable skirts that create sealed or partially sealed regions under the car, with the fans extracting air to lower the pressure and increase grip and stability.


Tesla pairs that with active wings, a next generation steer by wire system and a Track Mode that lowers the car and changes the suspension, with high downforce and low drag settings for the circuit. To keep weight down, Tesla points to magnesium, titanium and carbon fiber, manual controls and a fixed seat position, which it says lets the car respond to driver inputs almost instantly.

Tesla Roadster: Three configs, one can fly, 0-60 in 0.8 seconds

The cold gas thrusters are the other half. On the Thrust version they sit at the rear and Tesla says they take the car from 0 to 60 mph in under 0.9 seconds, while the Rocket version adds perimeter thrusters for forward, upward and lateral rotational movement. Tesla says the all electric actuators make micro adjustments within a fraction of a second.

Musk has been talking about records for years. In June 2019 he said, “We’re going to do things with the new Roadster that are kind of unfair to other cars.” That September, when a follower asked whether the Roadster would beat the Nürburgring production car record, he replied with one word, “Absolutely,” as we reported at the time. In February 2024 he said Tesla had “radically increased the design goals” for the car and that its sub one second 0 to 60 time would be “the least interesting part.”

There are caveats. Tesla has not published a lap time or a verified cornering figure, so the record talk is still a promise rather than a result. Tesla also says the car is not approved for public road use, and the thruster features are limited to the Rocket trim, which is invite only. Fan cars have also been banned or withdrawn before, and getting a sealed underbody to work on a rough public road is a harder problem than on a smooth track. The first real test will be an official lap at a circuit.

Tesla Roadster: Three configs, one can fly, 0-60 in 0.8 seconds

Tesla’s Roadster comes in Performance, Thrust and Rocket versions, with a claimed 0-60 under 0.59 seconds.

Tesla finally showed the next generation Roadster on Thursday night, and the demo had more in common with a SpaceX test than a track lap. At an event outside Waco, Texas, near SpaceX’s McGregor site, the car used a mix of fans and cold gas thrusters to drive up a curved ramp until it was upside down, then flew off, flipped and landed on the pavement. “Well, it worked,” Elon Musk said. “Flying cars are real.”

The Roadster also hovered itself over a Cybercab, Cybertruck, Tesla Semi, Model Y and Model 3 while moving, and that Tesla showed it going 0 to 60 mph in one second. Musk said “this will be the actual car that’s on the roads” and that it “literally is just going to puff itself up” to perform the maneuvers whenever an owner wants. He called the result a collaboration between Tesla and SpaceX engineers that is “better than any James Bond car,” with Franz von Holzhausen and Lars Moravy on site.

Tesla published new mind-blowing stats for the car that replace the previous targets. The Performance version is road ready and seats two, with active aerodynamics and a multi-mode suction system, and Tesla lists 0 to 60 mph in under 1.6 seconds. The Thrust version is race ready, also seats two, and adds rear-mounted cold gas thrusters for a 0 to 60 time of under 0.9 seconds. The Rocket version is described as air ready, seats one, and uses perimeter-mounted thrusters for forward and upward acceleration plus lateral rotational movement.

Configuration Seats 0 to 60 mph
Performance 2 under 1.6 s
Thrust 2 under 0.9 s
Rocket 1 under 0.59 s

Tesla’s own description: “So…yes, it can fly.” It lists a 0 to 60 time of under 0.59 seconds for Rocket, a top speed of up to more than 230 mph, and range of more than 300 miles. Tesla has not yet given pricing in the information we have seen, but has reopened $50,000 reservations in the newly updated Tesla Roadster configurator. Production is planned for Giga Texas in 2027 or 2028, and Musk has said it would follow the demo by 12 to 18 months.

Tesla’s Roadster page adds more on how the car works. A multi-mode fan and ground sealing system pulls air from under the car, producing enough suction to hold it upside down even when stationary. Active wings, steer-by-wire with a yoke, and a Track Mode that lowers the car round out the driving setup. The cold gas thrusters use all-electric actuators for micro adjustments to stabilize the car in flight. Tesla says it cut weight with magnesium, titanium and carbon fiber, manual controls and a fixed seat position, and the exterior has hidden headlights, a full-length taillight and Ano White paint inspired by aerospace coatings. Inside are an Ultrawhite interior with gray microsuede, a center touchscreen and two smaller forward displays, and gold tinted glass modeled on spacesuit visors. Availability is tiered: Performance is by reservation, Thrust is a limited release, and Rocket is invite only. Tesla notes the car is not approved for public road use, and that Rocket is not available in all regions.

Musk has described the Roadster as “the best of the last of the human-driven cars,” and he has been open that it is a halo product. He said he is “not sure it moves the needle massively from a revenue standpoint,” and has warned that anyone whose top priority is safety should not buy it. Tesla reports third quarter earnings on October 21.
