Tesla Model Y range estimate reduced by 6%, becoming more realistic
Tesla has updated its Model Y EPA range estimates, lowering the range of its Long Range and Performance models by 6% in its online configurator.
Specifically, the Model Y Long Range is down to 310 miles from 330, and the Model Y Performance is down to 285 miles from 303.
The cheapest Model Y, the Model Y Rear-Wheel Drive, which was introduced in the US in October, was not affected by the changes and retains its 260-mile range rating.
All three models have had no change in pricing since before the changes. The only changes we can see are the range estimates (and the two new colors).
We don’t know why Tesla has changed its range estimates, but it could have something to do with a change in the way Tesla does its EPA testing.
It has long been known that Tesla “vastly” overstates its range on its cars. While it is possible to meet EPA estimates if you drive efficiently (and I often do, or get close), Tesla tends to do disproportionately worse in real-world range tests than all other manufacturers, on a level playing field.
EPA tests allows some amount of discretion on the manufacturers’ part to raise or lower their range estimates by employing additional tests and applying an “adjustment factor.” Some manufacturers even apply a voluntary reduction to lower their range estimates, so that drivers are more likely to exceed estimates than come up short.
You can see Tesla’s overstatement for yourself: in a Tesla, charge your car up to 300 miles of range, then tell your car to navigate to somewhere that’s, say, 260 miles away. Your car will route you through a Supercharger, because Tesla’s real range estimate knows that its stated ranges are unrealistic.
So these ~6% changes won’t quite make up for all of Tesla’s range overstatement, but will bring the numbers closer to a realistic point.
However, this is only for two trims of the Model Y. We don’t know if Tesla’s other vehicles will end up having similar range estimate changes soon, although they all have suffered from the same range overstatement issue. So we would hope/expect to see corrections for other Tesla vehicles soon as well.
Electrek’s Take
At the end of the day, these range changes probably don’t really matter much. We don’t know what changed to get us here (and the company does not have a communications department to clarify changes like these when they happen), but Tesla tends to raise and lower the ranges of its cars randomly without any apparent physical changes to the battery, so really, nothing probably changed on the cars themselves.
Range is a fuzzy number anyway, meant to give a general idea of how far you can go, but can’t possibly take into account every situation in a single number. The phrase “Your Mileage May Vary” isn’t just informal slang – it originally applied to vehicle mileage, to describe how people will get different MPG in different situations. So, too, with range.
And frankly, I’m pretty tired of everyone treating range as the end-all-be-all of EV specs anyway. So while I dislike Tesla’s constant overstatement of range, making people think they need more range than they actually do and leading to ever-increasing range numbers beyond what’s realistically necessary (and leading to fewer larger, heavier, more expensive EVs in a constrained battery production landscape), I kind of do like when it randomly changes the range of its cars, showing everyone that the numbers are all made up anyway and you probably shouldn’t take them too seriously.
What’s more important is: learning to drive efficiently (if you need to go farther, slow down a bit), and ensuring that there are enough DC fast charge stations out there to give people a boost when they need it. If we all focus more on those things, then range will be something that we rarely need to think about anyway.

Mining company Vale is turning to Caterpillar to provide this massive, 240-ton battery-electric haul truck in a bid to slash carbon emissions at its mines by 2030.
Caterpillar and Vale have signed an agreement that will see the Brazilian mining company test severe-duty battery electric mining trucks like the 793 BEV (above), as well as V2G/V2x energy transfer systems and alcohol-powered trucks. The test will help Vale make better equipment choices as it works to achieve its goals of reducing direct and indirect carbon emissions 33% by 2030 and eliminating 100% of its net emissions by 2050.
If that sounds weird, consider that most cars and trucks in Brazil run on either pure ethyl alcohol/ethanol (E100) or “gasohol” (E25).
“We are developing a portfolio of options to decarbonize Vale’s operations, including electrification and the use of alternative fuels in the mines. The most viable solutions will be adopted,” explains Ludmila Nascimento, energy and decarbonization director Vale. “We believe that ethanol has great potential to contribute to the 2030 target because it is a fuel that has already been adopted on a large scale in Brazil, with an established supply network, and which requires an active partnership with manufacturers. We stand together to support them in this goal.”
Vale will test a 240-ton Cat 793 battery-electric haul truck at its operations in Minas Gerais, and put energy transfer solutions to a similar tests at Vale’s operations in Pará over the next two-three years. Caterpillar and Vale have also agreed to a joint study on the viability of a dual-fuel (ethanol/diesel) solution for existing ICE-powered assets.
Vale claims to be the world’s largest producer of iron ore and nickel, and says it’s committed to an investment of between $4 billion to $6 billion to meet its 2030 goal.
Cat 793 electric haul truck
During its debut in 2022, the Cat 793 haul truck was shown on a 4.3-mile test course at the company’s Tucson proving grounds. There, the 240-ton truck was able to achieve a top speed of over 37 mph (60 km/h) fully loaded. Further tests involved the loaded truck climbing a 10% grade for a full kilometer miles at 7.5 mph before unloading and turning around for the descent, using regenerative braking to put energy back into the battery on the way down.
Despite not giving out detailed specs, Caterpillar reps reported that the 793 still had enough charge in its batteries for to complete more testing cycles.
Electrek’s Take
Electric equipment and mining to together like peanut butter and jelly. In confined spaces, the carbon emissions and ear-splitting noise of conventional mining equipment can create dangerous circumstances for miners and operators, and that can lead to injury or long-term disability that’s just going to exacerbate a mining operation’s ability to keep people working and minerals coming out of the ground.
By working with companies like Vale to prove that forward-looking electric equipment can do the job as well as well as (if not better than) their internal combustion counterparts, Caterpillar will go a long way towards converting the ICE faithful.

Argonne National Laboratory is building a new research and development facility to independently test large-scale hydrogen fuel cell systems for heavy-duty and off-road applications with funding from the US Department of Energy.
The US Department of Energy (DOE) is hoping Argonne Nat’l Lab’s extensive fuel cell research experience, which dates back to 1996, will give it unique insights as it evaluates new polymer electrolyte membrane (PEM) fuel cell systems ranging from 150 to 600 kilowatts for use in industrial vehicle and stationary power generation applications.
The new Argonne test facility will help prove (or, it should be said, disprove) the validity of hydrogen as a viable fuel for transportation applications including heavy trucks, railroad locomotives, marine vessels, and heavy machines used in the agriculture, construction, and mining industries.
“The facility will serve as a national resource for analysis and testing of heavy-duty fuel cell systems for developers, technology integrators and end-users in heavy-duty transportation applications including [OTR] trucks, railroad locomotives, marine vessels, aircraft and vehicles used in the agriculture, construction and mining industries,” explains Ted Krause, laboratory relationship manager for Argonne’s hydrogen and fuel cell programs. “The testing infrastructure will help advance fuel cell performance and pave the way toward integrating the technology into all of these transportation applications.”
The Hydrogen and Fuel Cell Technologies Office (HFTO) of DOE’s Office of Energy Efficiency and Renewable Energy is dedicating about $4 million to help build the new Argonne facility, which is set to come online next fall.
Electrek’s Take
It’s going to be hard to convince me that the concentrated push for a technology as inefficient as hydrogen fuel cells has more to do with any real consumer or climate benefit than it does keeping the throngs of people it will take to manufacture, capture, transport, store, house, and effectively dispense hydrogen gainfully employed through the next election cycle.
As such, while case studies like the hydrogen combustion-powered heavy trucks that have been trialed at Anglo American’s Mogalakwena mine since 2021 (at top) and fuel cell-powered concepts like Komatsu’s medium-sized excavator (above) have proven that hydrogen as a fuel can definitely work on a job site level while producing far fewer harmful emissions than diesel, I think swappable batteries like the ones being shown off by Moog Construction and Firstgreen have a far brighter future.
Speaking of Moog, we talked to some of the engineers being their ZQuip modular battery systems on a HEP-isode of The Heavy Equipment Podcast a few months back. I’ve included it, below, in case that’s something you’d like to check out.

Velocity truck rental is doing its part to help commercial fleets electrify by energizing 47 high-powered charging stations at four strategic dealer locations across Southern California. And they’re doing it now.
The new Velocity Truck Rental & Leasing (VTRL) charging network isn’t some far-off goal being announced for PR purposes. The company says its new chargers are already in the ground, and set to be fully online and energized by the end of this month at at VTRL facilities in Rancho Dominguez (17), Fontana (14), the City of Industry (14), and San Diego (2).
45 120 kW Detroit e-Fill chargers make up the bulk of VTRL’s infrastructure project, while two DCFC stations from ChargePoint get them to 47. All of the chargers, however, where chosen specifically to cater to the needs of medium and heavy-duty battery electric work trucks.
The company says it chose the Detroit e-Fill commercial-grade chargers because they’ve already proven themselves in Daimler-heavy fleets with their ability to bring Class 8 Freightliner eCascadias, Class 6 and 7 Freightliner eM2 box trucks, and RIZON Class 4 and 5 cabover trucks, “to 80% state of charge in just 90 minutes or less.”
At Velocity, we are not just reacting to the shift towards electric mobility; we are at the forefront with our customers and actively shaping it. By integrating high-powered, commercial-grade charging solutions along key transit corridors, we are ensuring that our customers have the support they need today. This charging infrastructure investment is a testament to our commitment to helping our customers transition smoothly to electromobility solutions and to prepare for compliance with the Advanced Clean Fleets (ACF) regulations.
David Deon, velocity president
Velocity plans to offer flexible charging options to accommodate the needs of different fleets, including both managed, “charging as a service” subscription plans and self-managed/opportunity charging during daily routes. While trucks are charging, drivers and operators will be able to relax in comfortable break rooms equipped with WIFI, television, snacks, water, and restrooms.
Electrek’s Take
While it feels a bit underwhelming to write about trucking companies simply following the letter of the law in California, the rollout of an all-electric, zero-emission commercial trucking fleet remains something that, I think, should be celebrated.
As such, I’m celebrating it. I hope you are, too.
