Tesla Model S
Charging the Tesla Model S with the HPWC
When I was buying my Model S I decided that I didn’t need the High Power Wall Charger (HPWC), but I did go with the dual chargers. At home I regularly charge on a NEMA 14-50 which gives me about 28 miles per 1 hour of charge, but with the onboard dual chargers it’s possible to double that rate provided you’re using the proper charger.
My office is across the street from the Tesla store in Natick, MA and they have free charging available in 6 parking spots with a couple of HPWCs a short walk away. The other day I skipped my nightly charge and parked in one of the HPWC spots at the mall for a charge the next morning.
Tesla HPWC
The HPWC does not require any special adapters or additional cables and simply plugs into the Model S. It charges at up to 80A when equipped with the Model S dual chargers, but even without it things still work – just at half the charge rate. That’s what I love about the Tesla. Even if you know nothing about voltages, amperages and watts, things just work. Just plug, play and Tesla manages the rest.
Charging
Unlike the Tesla Supercharger which uses a direct current (DC) that bypasses the onboard chargers, the HPWC uses a more traditional alternating current (AC) approach, but with a very high amp draw.
There are very few public chargers out there that can charge at over 40A, and the ones that do probably don’t have a Tesla Model S adapter such as the CHAdeMO.
Editor’s note: Tesla Motors loaned PlugShare a custom CHAdeMO to Model S adapter for their epic 12,000+ mile journey.
The Model S has the ability to charge at different amperages depending on your setting. The rate is limited by both your car’s ability (40A or 80A for single or dual chargers respectively) and the maximum draw allowed by your power source. Make sure your charge rate is set to the highest limit before plugging into a HPWC in order to maximize your rate of charge. The charge rate settings should be auto-memorized by the vehicle based on your GPS location.
Charge Rate
After I confirmed that the car was charging, I walked to my office while monitoring my state of charge through the iOS app. It reported the charge rate to be about 50 miles/hour (208v at 81A) which confirmed that my dual chargers were working since I was charging twice as fast as my home NEMA 14-50.
To validate the rate of charge I timed the charge and recorded the reported rated range. I started charging at 8:30am and stopped at 11:07 AM (a 90% charge limit was set). I went from 106 miles of rated range to 240 miles of rated range. So I added 134 miles in 2.6 hours for an actual charge rate of 51.2 miles/hour.
I’ve heard about charge rates tapering off as your near the upper limits of your charge, but in my case it charged at the same rate all the way to a 90% limit. I’m assuming that the charge rate begins to slow down after the 90% mark, but unfortunately I didn’t have a chance to confirm that this time around.
Summary
My main goal was to be able to test my onboard dual chargers – something I debated long and hard on when ordering my Model S. I wanted to see them in action and gain peace of mind that they’re there and ready for fast charging if I should one day need it while on the road without access to a Tesla Supercharger.
The HPWC worked great and provided a high rate of charge that was twice the speed of my home NEMA 14-50. But even with that I still don’t think a HPWC at home is really needed.

Tesla announced its Spring 2026 software update, and it’s the most feature-dense seasonal release the company has put out. The update covers twelve named changes spanning FSD, voice AI, safety lighting, dashcam storage, and pet display customization, among other things.
The centerpiece for owners with AI4 hardware is a redesigned Self-Driving app. The new interface lets owners subscribe to Full Self-Driving with a single tap and view ongoing FSD usage stats directly in the vehicle.
Grok gets its biggest in-car upgrade yet. The update adds a “Hey Grok” hands-free wake word along with location-based reminders, so a driver can now say “remind me to pick up groceries when I get home” without touching the screen. Grok first arrived in vehicles in July 2025, but each update has pushed it closer to genuine daily utility. Musk framed the broader vision clearly at Davos in January, saying Tesla is “really moving into a future that is based on autonomy.”
On safety, the update introduces enhanced blind spot warning lights that integrate directly with the cabin’s ambient lighting, building on the blind spot door warning that arrived in update 2026.8.
Dog Mode has been renamed Pet Mode and now lets owners choose a dog, cat, or hedgehog icon and add their pet’s name to the display.
Dashcam retention now extends up to 24 hours, up from the previous one-hour rolling loop, with a permanent save option for any clip. Weather maps now show rain and snow with better color differentiation and include the past hour of precipitation data along the route.
Tesla has now established a clear rhythm of two major OTA pushes per year. As with last year’s Spring update, that cycle started taking shape in 2025 with adaptive headlights and trunk customization. The 2025 Holiday Update then added Grok to the vehicle for the first time. This Spring follows that structure: the Holiday update introduces new architecture, and the Spring update broadens it across the fleet.
Two notable features still did not make it. IFTTT automations, which launched in China earlier this year, were held back from this North American release for unknown reasons, and Apple CarPlay remains absent, reportedly still delayed by iOS 26 and Apple Maps compatibility issues.
Below is the full list of feature updates released by Tesla.

Tesla launches 200mph Model S “Gold” Signature in invite-only purchase
Tesla’s final 350-unit Signature Edition closes the book on two cars that changed everything.
Tesla has announced a super limited Signature Edition run of 250 Model S Plaid and 100 Model X Plaid units as an invite only purchase in a bid to give its original flagship vehicles a proper send-off.
When the Model S first launched in 2012, the first 1,000 units sold were “Signature” editions that required a $40,000 deposit and cost nearly $100,000 each. Those early buyers were Tesla’s first real believers. This new Signature Edition deliberately echoes that moment, bookending a 14-year run with numbered collector hardware.
Both models are finished in an exclusive Garnet Red paint not available on any current Tesla production vehicle, with gold Tesla T badges up front, a gold Plaid badge and Signature badge at the rear, and a white Alcantara interior featuring gold Plaid seat badges, gold piping, Signature-marked door sills, and a numbered dash plate. The Model S adds carbon ceramic brakes with gold calipers. Every unit ships with Tesla’s Luxe Package, bundling Full Self-Driving (Supervised), four years of Premium Service, free lifetime Supercharging, and a Signature Edition key fob. Both are priced at $159,420, a roughly $35,000 premium over standard Plaid inventory.
The discontinuation is part of a broader strategic shift. At Tesla’s Q4 2025 earnings call, Musk described the decision as “slightly sad” but necessary, saying: “It’s time to basically bring the Model S and X programs to an end with an honorable discharge, because we’re really moving into a future that is based on autonomy.”
The Fremont factory floor that built these cars is being converted to manufacture Optimus humanoid robots, with a target of one million units annually.

Tesla uses Model S and X ‘sentimental’ value to enforce massive pricing move
By slashing production and creating immediate scarcity, the company has transformed these remaining vehicles into limited-edition relics. The price hike is not driven by rising material costs or new features.
Tesla is using the “sentimental” value that CEO Elon Musk talked about with the Model S and Model X to enforce one of the most massive pricing moves it has ever applied as it begins to phase out the flagship vehicles.
Tesla quietly executed one of its most calculated pricing plays yet. After officially ending production of the Model S and Model X, the company raised prices on every remaining new and demo unit by roughly $15,000.
The refreshed starting prices now sit at:
- $109,990 for the Model S AWD
- $124,900 for the Model S Plaid
- $114,900 for the Model X AWD
- $129,900 for the Model X Plaid
NEWS: Tesla has raised the price on all remaining new (and demo) Model S and Model X vehicles left in inventory by $15,000.
New starting prices:

• Model S Plaid: $124,900
• Model X AWD: $114,900

Every vehicle comes fully loaded with the Luxe Package, Full Self-Driving Supervised, four years of premium connectivity and service, and lifetime free Supercharging. What looks like a simple inventory adjustment is, in reality, a masterclass in monetizing nostalgia.
These are not ordinary cars. For many owners, the Model S and Model X represent the purest expression of Tesla’s original promise—the sleek, over-engineered flagships that proved electric vehicles could be faster, quieter, and more desirable than their gasoline counterparts.
Tesla removes Model S and X custom orders as sunset officially begins
They are the vehicles that carried Elon Musk’s vision from Silicon Valley startup to global automaker.
The final units rolling off the line carry an emotional weight that numbers alone cannot capture. Buyers are not simply purchasing transportation; they are acquiring a piece of Tesla history, the last examples of the very models that defined the brand’s first decade.
Tesla, with this move, understands this sentiment deeply.
By slashing production and creating immediate scarcity, the company has transformed these remaining vehicles into limited-edition relics. The price hike is not driven by rising material costs or new features.
It is driven by the knowledge that a certain segment of buyers, loyalists, collectors, and enthusiasts, will pay a premium precisely because these cars are about to disappear. The strategy converts emotional attachment into margin.
Where other automakers might discount outgoing models to clear lots, Tesla is betting that sentiment is worth more than volume.
The move also quietly rewards existing owners. Scarcity instantly boosts resale values for the hundreds of thousands of Model S and X already on the road, reinforcing brand loyalty among the very people who helped build Tesla’s reputation.
In the end, Tesla’s pricing decision reveals a sophisticated understanding of its audience. As the company pivots toward next-generation platforms, it has found a way to extract one final, lucrative chapter from its heritage.
For buyers willing to pay the new prices, the premium is not just for the car; it is for the feeling of owning the last true originals. Tesla has turned sentiment into strategy, and in the process, reminded everyone that even in the EV era, emotion remains a powerful line on the balance sheet.
