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.

Tesla Megapack powers $1.1B AI data center project in Brazil
By integrating Tesla’s Megapack systems, the facility will function not only as a major power consumer but also as a grid-supporting asset.
Tesla’s Megapack battery systems will be deployed as part of a 400MW AI data center campus in Uberlândia, Brazil. The initiative is described as one of Latin America’s largest AI infrastructure projects.
The project is being led by RT-One, which confirmed that the facility will integrate Tesla Megapack battery energy storage systems (BESS) as part of a broader industrial alliance that includes Hitachi Energy, Siemens, ABB, HIMOINSA, and Schneider Electric. The project is backed by more than R$6 billion (approximately $1.1 billion) in private capital.
According to RT-One, the data center is designed to operate on 100% renewable energy while also reinforcing regional grid stability.
“Brazil generates abundant energy, particularly from renewable sources such as solar and wind. However, high renewable penetration can create grid stability challenges,” RT-One President Fernando Palamone noted in a post on LinkedIn. “Managing this imbalance is one of the country’s growing infrastructure priorities.”
By integrating Tesla’s Megapack systems, the facility will function not only as a major power consumer but also as a grid-supporting asset.
“The facility will be capable of absorbing excess electricity when supply is high and providing stabilization services when the grid requires additional support. This approach enhances resilience, improves reliability, and contributes to a more efficient use of renewable generation,” Palamone added.
The model mirrors approaches used in energy-intensive regions such as California and Texas, where large battery systems help manage fluctuations tied to renewable energy generation.
The RT-One President recently visited Tesla’s Megafactory in Lathrop, California, where Megapacks are produced, as part of establishing the partnership. He thanked the Tesla team, including Marcel Dall Pai, Nicholas Reale, and Sean Jones, for supporting the collaboration in his LinkedIn post.

Starlink powers Europe’s first satellite-to-phone service with O2 partnership
The service initially supports text messaging along with apps such as WhatsApp, Facebook Messenger, Google Maps and weather tools.
Starlink is now powering Europe’s first commercial satellite-to-smartphone service, as Virgin Media O2 launches a space-based mobile data offering across the UK.
The new O2 Satellite service uses Starlink’s low-Earth orbit network to connect regular smartphones in areas without terrestrial coverage, expanding O2’s reach from 89% to 95% of Britain’s landmass.
Under the rollout, compatible Samsung devices automatically connect to Starlink satellites when users move beyond traditional mobile coverage, according to Reuters.
The service initially supports text messaging along with apps such as WhatsApp, Facebook Messenger, Google Maps and weather tools. O2 is pricing the add-on at £3 per month.
By leveraging Starlink’s satellite infrastructure, O2 can deliver connectivity in remote and rural regions without building additional ground towers. The move represents another step in Starlink’s push beyond fixed broadband and into direct-to-device mobile services.
Virgin Media O2 chief executive Lutz Schuler shared his thoughts about the Starlink partnership. “By launching O2 Satellite, we’ve become the first operator in Europe to launch a space-based mobile data service that, overnight, has brought new mobile coverage to an area around two-thirds the size of Wales for the first time,” he said.
Satellite-based mobile connectivity is gaining traction globally. In the U.S., T-Mobile has launched a similar satellite-to-cell offering. Meanwhile, Vodafone has conducted satellite video call tests through its partnership with AST SpaceMobile last year.
For Starlink, the O2 agreement highlights how its network is increasingly being integrated into national telecom systems, enabling standard smartphones to connect directly to satellites without specialized hardware.
