Updated: Tesla Model Y specification discrepancy has experts scratching their heads
Update: 5/3 12:40 pm est: Tesla has updated the specifications of the Model Y RWD in North America. See para. 3
A discrepancy in the Tesla Model Y’s specifications leaves experts and fans confused and wondering what will come to the United States.
Tesla has always been at least a little tight-lipped about its engineering and design, and this pseudo-secrecy certainly isn’t aided by its lack of a communications team. However, this has come to a head recently as fans have discovered a discrepancy in the specifications of Tesla’s newest offering, the rear-wheel-drive single-motor Model Y, which currently is only sold in select markets.
The Tesla Model Y spec discrepancy was first identified by Mathias Føns on Twitter, who pointed out that the Model Y RWD sold in North America is significantly heavier and charges substantially faster than its counterpart abroad.
The??Tesla Model Y RWD that recently launched has head-scratching specs
It weighs 319kg more than the??MY LR
Furthermore, it weighs 389kg more than the??MY RWD, has 47% higher max supercharging capabilities & ~15 km lower range (WLPT→EPA)

Since its discovery, Tesla has updated its website, decreasing the weight listed in North America to match the global model. However, the Model Y RWD outside of North America still charges at 170kW, while its North American counterpart charges at 250kW. Tesla has not publically addressed this disparity.
Looking at the spec sheets posted on Tesla websites worldwide, the heavier and faster charging Model Y RWD is only being sold in North America, including both Canada and Mexico, though the vehicle is not yet available in the States. In contrast, models sold in Australia, Europe, and Asia are lighter and charge significantly slower. Specifically, the North American model is 389kg (857.6 lbs) heavier than its global counterpart and charges almost twice as fast, 250kW vs. 170kW. The listed weight of the model sold in China is 2kg heavier than the one sold in Europe, but it has the same recorded charging speed.
The two models also seem to differ slightly in estimated range, though they aren’t precisely comparable considering they use entirely different testing schedules; EPA in North America, WLTP in Europe and Australia, and CLTC in China.
Strangely, this discrepancy continues when comparing the Model Y RWD with the Model Y Long-Range AWD sold in the same market. According to the Tesla Canada website, the RWD is 319kg (703.3 lbs) heavier than the LR AWD, though they charge at the same speed, 250kW.
While some have hypothesized that this weight difference has to do with how the weight is measured in each country, the more likely difference, which could also explain the dramatic difference in charging speed, is battery chemistry. Tesla does not list this difference on its website. Still, using lithium iron phosphate (LFP) batteries in North America would explain the incredible weight difference and the charging speed increase, that is, if the global model is using a lithium nickel manganese cobalt (NMC) battery.

Tesla CEO Elon Musk has previously noted that the automaker plans to switch all of its lower-priced offerings to the cheaper-to-produce LFP battery, further adding credence to the battery chemistry hypothesis.
With Tesla expected to continue to grow the reach of each of its product lines, many anticipate it will only be a matter of time before the RWD variant of the Model Y makes its way to Tesla’s home market, the United States. And with the rest of North America already using the heavier, faster charging model, Americans should expect access to this variant instead of the global version.
Along with the charging speed bump, the LFP battery would provide significantly improved durability and battery lifespan compared to those sold in Europe, Asia, and Australia.

The real reason Elon Musk wants every car connected to space
Elon Musk says all cars will eventually need Starlink to handle massive AI bandwidth demand.
Elon Musk is making the case that satellite internet, not fiber or cellular towers, will end up wired into every car on the road. In a string of posts on X, the SpaceX CEO wrote that all cars will have Starlink in the future and called satellite connectivity the only way to get super high bandwidth to billions of vehicles.
The posts started with Musk endorsing a Cloudflare forecast that traffic generated by autonomous AI agents will soon dwarf traffic generated by humans browsing the internet, a shift he described as not a close call at all. From there he narrowed the argument to infrastructure, writing that the only system that can support the insanely fast bandwidth growth needed by AI is Starlink, before extending the logic to cars specifically.
AI agentic Internet traffic will obviously VASTLY exceed human usage. Not a close call at all.
Cloudflare’s forecast is accurate. https://t.co/VztgrinN5k pic.twitter.com/Wo4FiRKjPU

The timing lines up with Tesla’s own hardware decisions. On July 20, Tesla confirmed the Cybercab would ship with a Starlink V5 terminal built into its roof, the first time the company had put satellite hardware in a production vehicle. A day later, Tesla’s head of AI, Ashok Elluswamy, explained the connection wasn’t there for safety and that Cybercab’s driving stack runs entirely on onboard cameras and compute, while the satellite link exists for navigation, customer service, and fleet management instead. Musk followed with his own post about the feature, saying riders would be able to watch 4K streaming video during rides.
By July 22, Musk had already said Starlink would extend beyond Cybercab to Tesla’s full lineup. Sunday’s posts push that same logic outward again, this time framed as a requirement across the industry rather than a feature specific to Tesla, and tied directly to the bandwidth AI systems are expected to consume.
SpaceX’s newest Starmind will make earth data centers obsolete

The AI argument has been building on SpaceX’s side for months. The company has an FCC filing pending for a third generation Starlink constellation, and it has separately proposed Starmind, a constellation of up to a million satellites designed to run AI computation directly in orbit rather than just relay data. Musk has said he expects space to become the cheapest place to deploy AI compute within two to three years. Starlink and Starmind serve different jobs inside that vision, one moving data and the other processing it, but Sunday’s posts treat vehicles as one more category of hardware that will eventually need both.
None of this changes anything for Tesla owners today. Cars already on the road keep running on LTE and Wi-Fi, and Tesla hasn’t outlined a retrofit path for existing vehicles. The July 22 commitment applies to future production, not the fleet already delivered. What Musk added on Sunday is the reasoning: satellite connectivity isn’t a Cybercab novelty, it’s a bet that ground based networks won’t keep up with how much data cars, robots, and AI systems are about to generate.

The Boring Company’s newest tunnel vehicle runs on Tesla parts and no one is driving it
The Boring Company’s new tunnel vehicle runs on Tesla Model 3 batteries and drive units.
The Boring Company just introduced a new piece of hardware, and it runs on parts pulled straight from a Tesla showroom. Liner Truck 3, unveiled in a post from the tunneling company’s official X account, is an all electric vehicle built around Tesla Model 3 battery packs and drive units, purpose built to move concrete tunnel segments to the boring machine face without a single person underground.
Introducing Liner Truck 3 — our latest fully electric tunnel vehicle.
– Tesla Model 3 battery and drive units
– Transports 22,000+ lb of concrete segments to the boring machine
– 28 miles of range
– 12 mph max operating speed
– Remotely piloted from Global OCC in Texas, with… pic.twitter.com/XB7FgSXnpy— The Boring Company (@boringcompany) August 7, 2026
The job itself is unglamorous but critical. Each precast segment run weighs more than 22,000 pounds, roughly the load of a full cement mixer, and Liner Truck 3 hauls that weight repeatedly between the surface staging area and wherever the Prufrock machine happens to be cutting.
The Boring Company said Liner Truck 3 is piloted remotely out of its Global Operations Control Center in Texas, extending the Zero-People-In-Tunnel approach the company has spent years building toward. An earlier version of a ZPIT liner truck was already tested at the company’s Bastrop, Texas research tunnels, and a factory tour released last month showed an employee flying a fully loaded liner truck with a PlayStation controller. Liner Truck 3 looks like the production version of that same idea, cleaned up and pushed into daily use.
The timing lines up with a company digging in more places than it ever has before. The Boring Company now has multiple Prufrock machines active or arriving in Nashville, where Music City Loop construction has been accelerating since February, and its Vegas Loop network keeps adding tunnel mileage on a near monthly basis. Every one of those projects depends on getting concrete segments to the cutting face fast enough to keep the boring machine from idling, which is exactly the bottleneck Liner Truck 3 is designed to remove.

It also reinforces something Tesla owners have watched happen gradually across Musk’s companies: passenger car hardware finding a second life in heavy equipment. Model 3 drive units already move people through the Vegas Loop, and now the same components are hauling concrete underground in Nashville and wherever The Boring Company digs next. Whether that kind of component reuse extends further into TBC’s equipment lineup, or into other Musk owned industrial hardware, is the next thing worth watching.
SpaceX stock did the opposite of what most of Wall Street expected this week, when the day designed to be its most dangerous turned into a rally, and the rally kept going.
Thursday marked the first major lockup expiration since SpaceX’s June IPO, making roughly 911.5 million insider held shares eligible to trade for the first time, more than doubling the company’s public float. Analysts and short sellers had spent weeks bracing for a flood of selling, especially after the stock fell 13 percent following its first earnings report as a public company on Tuesday. Instead, shares rose 6.1 percent Thursday to close at $114.92, and by Friday they were trading near $129, up more than another 12 percent on the day.

The setup made the outcome notable. Short interest had climbed to roughly 34 percent of the float heading into earnings, among the highest of any large cap stock, with about 95 percent of available shares to borrow already on loan. CEO Elon Musk warned short sellers twice in the weeks before the lockup, writing on X that “the survival probability of firms who maintain a significant short position in SpaceX over time is very low,” then following up on the morning of earnings with “I try to warn them, but they just double down.”
When the newly unlocked shares hit the market and the selloff never showed up, some of that short position appears to have started unwinding. TipRanks reported that options activity shifted toward bullish strategies like put selling and risk reversals following the rally, with roughly $600 million in options premium trading Thursday alone. Retail buyers also stepped in during the earnings dip, according to Vanda Research.
The fundamentals behind the stock have not changed much in a week. SpaceX’s revenue nearly doubled year over year to $7.8 billion, with Starlink subscribers doubling to 12 million and the company’s AI segment growing 247 percent. What spooked investors on Tuesday was the spending side. Capital expenditures jumped to more than $18 billion for the quarter, up from $2.8 billion a year earlier, with AI investment alone rising from $749 million to $15.8 billion. Wall Street remains split on whether that spending is building infrastructure SpaceX needs or outrunning what the business can currently support, a debate Teslarati has tracked since shares first came under pressure.
None of that resolves the bigger question hanging over the stock. Thursday’s release was only the first of nine staggered lockup tranches, with roughly $800 billion worth of additional shares scheduled to become eligible through October, and Musk’s own stake stays locked until next June. If this week is any indication, the market is treating that supply as something it can absorb rather than something to fear, at least for now.
