There’s an article in “The Drive” that’s been repeated in other media. Here’s a link if you want to read the whole article.
It’s not important in your day-to-day driving since few people use up all the electricity in their Tesla on a normal day. But, if you have lots of driving scheduled for a day, or if you’re taking a cross-country trip, you have to make allowances for this particularly Tesla problem.
The Results of the Tests
Edmunds, which does reviews on all cars, and which has rated the Tesla Model 3 as the number one best electric vehicle, found that none of the models of Tesla met the EPA range estimates as advertised by Tesla. None of the models. All the other electric cars easily went 20 to 50 miles past their EPA-rated ranges.
Tesla’s Response
Naturally, the Tesla engineers weighed in, but what they said was not very helpful. They said that the reason the Teslas failed to reach the EPA range is that Edmunds didn’t keep driving them until they couldn’t go an inch farther. Edmunds stopped driving when the range number on the screen went down to zero. So Edmunds repeated the testing and kept driving until the cars actually stopped. Tesla calls this a safety buffer.
Don’t Plan on Using the Safety Buffer
Don’t plan on using the safety buffer. It’s terrible for the battery. It’s just as bad as charging your battery up to 100% and then letting it sit overnight. Don’t do that either. Bad.
Be Kind to Your Battery
We want our batteries to last as long as the rest of the car. So, in my case, I charge to 80% every night. That way, I’m not damaging the battery, and I have more miles than I need for day-to-day driving. I do plan on taking the Tesla on road trips once this furshlugginer pandemic is over. I have the SR+ which, in theory, can go 250 miles on a charge. I won’t plan on 250 miles between supercharges. When my car was new, and I had 1,000 miles or six months of free supercharging, whichever came first, I didn’t actually need any supercharging. Not going anywhere. Pandemic y’know. The six months came first.
My Supercharging Experience
But, since supercharging was included in the price of my car, any time I needed to go somewhere near a supercharger, I went ahead and used the service. Here’s what I found. When the battery is low, the supercharger gives extremely rapid charging. I can’t tell you the exact rate of charge because different superchargers give different rates of charge depending on which generation of supercharger you’re using. But as a general rule, you’ll get extremely rapid charging when the battery is low. You’ll probably get to 80% in 30 to 40 minutes. That last 20% will take longer. A lot longer.
Suggested Strategy
You’ll probably do better in total trip time if you don’t wait around for the last trickle of energy to fill your battery to 100%. Between 80% and 90%, the charging goes painfully slowly. Between 90% and 100%, the charge slows to a trickle. You’ll stop a bit more often, but you’ll spend less total time on the chargers during your trip if you just charge to 80% each time you need to charge. When I take my trip, I’ll be sure to let you know how it goes.
Public Health Advice
One last thought for car trips. Elon Musk gives you video games to entertain yourself during a supercharger stop. If you’re on a trip, don’t play the video games. Get out of the car and walk around. Sitting in a car for long periods of time can cause blood clots in your legs. Don’t let that happen.
Tesla recently launched software update 2025.8.3, which included a bunch of “minor updates.” Nestled away in the release notes are a couple of interesting features - including some major changes to the Energy App.
We’re not quite sure we’d call these minor updates, so let’s take a bit of an exploration of the revitalized Energy App.
The Energy App has received some new categorization features in the Consumption tab. You can once again limit the graph by distance. As part of the 2024 Holiday Update, Tesla redesigned the consumption tab and brought it to the new Model S and Model X for the first time. However, with the redesign, Tesla removed the ability to choose the distance shown in the graph, instead providing a static display of the last 200 miles (300km).
The first part of the improved Energy App is bringing back this distance filter. You can now choose between showing the last 10, 100, or 200 miles (15, 150, or 300 km). This differs from the previous available distances of 5, 15 and 30 miles, but brings back the ability for the driver to choose a distance that may be more applicable to how they’re driving.
We’d love for Tesla to introduce custom distances by pinching and zooming the graph or simply add the ability to choose “This Drive Only” to the list of available distances.
Reset Energy App History
@EV3_Model3 on X
Sadly, the “Instant Range” button that was available in the Energy App before is still not available, but Tesla introduced a new feature that may be even better. You can now clear your driving history so that the graph only reflects your current driving style.
This is a little hidden, but if you tap the little info icon at the top near your average Wh/mi, you’ll now be presented with a dialog that lets you clear your history.
This could be useful if you’ve just come from some hard driving on a track or off-road, where energy consumption could be exaggerated. It could also be useful if you just started towing or a different type of driving that is drastically different from your current driving.
Other Changes
In addition, it looks like future predictions of the Energy app now take into account your driving history and apply that in addition to expected vehicle consumption, weather, altitude, and the multitude of other factors that your Tesla constantly takes into account while calculating your expected range.
While these are smaller improvements to the Energy app, they added some important functionality, as it helps users better understand their vehicle consumption and display data that is more applicable to the current driving style.
This is a great example of Tesla listening to its customers and bringing back features they had previously been removed. Check out the video below by akide on the updated Energy app in update 2025.8.3.
Sandy Munro once again had the opportunity to chat (video below) with Lars Moravy, Tesla’s Vice President of Vehicle Engineering, as well as Franz Von Holzhausen, Tesla’s Chief of Vehicle Design. This time, rather than focusing on the improvements to the refreshed Model Y and all the new engineering behind it, the focus was on Tesla’s autonomous ambitions.
In this case, the Cybercab and Robovan were the key highlights, with a distinct focus on the Cybercab. With that all said, let’s dig into all the fun new stuff. You can check out the entire video at the end of the article.
Cybercab Unboxed Process
The Cybercab will be the first of Tesla’s vehicles to use their new unboxed assembly process, which builds vehicles in parallel sections, and then brings them together all at once for final assembly. Traditionally, vehicles are assembled from the ground up, and sometimes even disassembled for parts of production to take place.
This innovative method involves using a big rear and front casting, brought together by a structural battery pack on the floor. The door rings are hot-stamped and laser-welded to form the side shell of the Cybercab, resulting in a very rigid structure that can also absorb crash impacts due to its unique manufacturing.
Paint-Free Panels
We’ve already talked about the Cybercab’s unique paint-free panels, but we’ve never heard until now exactly how Tesla intends to manufacture them. Tesla will inject colored PU plastic onto the backside of another plastic part (formed from various processes) and then ultrasonically weld that entire piece to an inner part.
That essentially combines multiple parts into one smooth piece that is easy to repair - because all you have to do is remove the entire panel - it just comes off as the interior fasteners are removed. There is no subframe holding it together - instead, the subframe is part of the panel.
The only area of the vehicle that will have any paint will be the hot-stamped door rings - which will be painted to improve corrosion resistance to protect the steel.
Aerodynamics
Aerodynamically, the Cybercab boasts the largest aero-cover-to-wheel ratio of any Tesla vehicle. This updated aero cover improves efficiency, even with the Cybercab’s relatively large tires—chosen to reduce rolling resistance. Interestingly, the impact of unsprung weight on efficiency is minimal compared to the benefits of improved rolling resistance and aerodynamics.
Another key to the aerodynamics is the teardrop shape of the Cybercab itself. With its low profile and smooth shape, it is extremely aerodynamically efficient. While neither Sandy nor Lars delved into drag coefficients, we expect it will likely be more efficient than the Model 3’s already fantastic Cd of 0.219.
Range and Battery Pack
Tesla currently has prototypes undergoing real-world testing at Giga Texas to evaluate range and efficiency. The goal is to ensure the vehicle can operate throughout an entire day in the city before returning to charge.
Tesla is targeting a battery pack under 50kWh, delivering close to 300 miles of real-world range—an impressive efficiency of around 166Wh/mi, even outperforming the Model 3’s lowest at 181Wh/mi.
When Does It Arrive?
So, with all that new knowledge - when does the Cybercab arrive? Well - the prototypes for the June Robotaxi network deployment in Austin are getting prepared now - but Tesla expects to begin production and sales sometime in the first half of 2026.
