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.

GM CEO Mary Barra says she told Biden to give Tesla and Musk EV credit
“He was crediting me, and I said, ‘Actually, I think a lot of that credit goes to Elon and Tesla…You know me, Andrew. I don’t want to take credit for things.”
General Motors CEO Mary Barra said in a new interview on Wednesday that she told President Joe Biden to credit Tesla and its CEO, Elon Musk, for the widespread electric vehicle transition.
She said she told Biden this after the former President credited her and GM for leading EV efforts in the United States.
During an interview at the New York Times Dealbook Summit with Andrew Ross Sorkin, Barra said she told Biden that crediting her was essentially a mistake, and that Musk and Tesla should have been explicitly mentioned (via Business Insider):
“He was crediting me, and I said, ‘Actually, I think a lot of that credit goes to Elon and Tesla…You know me, Andrew. I don’t want to take credit for things.”
GM CEO Mary Barra said to Andrew Sorkin at the New York Times Dealbook Summit that she pulled President Biden aside and said Tesla CEO @elonmusk deserved the credit for EVs:

Back in 2021, President Biden visited GM’s “Factory Zero” plant in Detroit, which was the centerpiece of the company’s massive transition to EVs. The former President went on to discuss the EV industry, and claimed that GM and Barra were the true leaders who caused the change:
“In the auto industry, Detroit is leading the world in electric vehicles. You know how critical it is? Mary, I remember talking to you way back in January about the need for America to lead in electric vehicles. I can remember your dramatic announcement that by 2035, GM would be 100% electric. You changed the whole story, Mary. You did, Mary. You electrified the entire automotive industry. I’m serious. You led, and it matters.”
People were baffled by the President’s decision to highlight GM and Barra, and not Tesla and Musk, who truly started the transition to EVs. GM, Ford, and many other companies only followed in the footsteps of Tesla after it started to take market share from them.

Musk would eventually go on to talk about Biden’s words later on:
“They have so much power over the White House that they can exclude Tesla from an EV Summit. And, in case the first thing, in case that wasn’t enough, then you have President Biden with Mary Barra at a subsequent event, congratulating Mary for having led the EV revolution.”
In Q4 2021, which was shortly after Biden’s comments, Tesla delivered 300,000 EVs. GM delivered just 26.

Tesla Full Self-Driving shows confident navigation in heavy snow
So far, from what we’ve seen, snow has not been a huge issue for the most recent Full Self-Driving release. It seems to be acting confidently and handling even snow-covered roads with relative ease.
Tesla Full Self-Driving is getting its first taste of Winter weather for late 2025, as snow is starting to fall all across the United States.
The suite has been vastly improved after Tesla released v14 to many owners with capable hardware, and driving performance, along with overall behavior, has really been something to admire. This is by far the best version of FSD Tesla has ever released, and although there are a handful of regressions with each subsequent release, they are usually cleared up within a week or two.
Tesla is releasing a modified version of FSD v14 for Hardware 3 owners: here’s when
However, adverse weather conditions are something that Tesla will have to confront, as heavy rain, snow, and other interesting situations are bound to occur. In order for the vehicles to be fully autonomous, they will have to go through these scenarios safely and accurately.
One big issue I’ve had, especially in heavy rain, is that the camera vision might be obstructed, which will display messages that certain features’ performance might be degraded.
So far, from what we’ve seen, snow has not been a huge issue for the most recent Full Self-Driving release. It seems to be acting confidently and handling even snow-covered roads with relative ease:

I found the steepest, unplowed hill in my area and tested the following:
• FSD 14.2.1 on summer tires
• FSD 14.2.1 on winter tires
• Manual drivingBut I think the most impressive part was how FSD went DOWN the hill. FSD in the snow is sublime $TSLA pic.twitter.com/YMcN7Br3PU

Well.. I couldn’t let the boys have all the fun!
Threw the GoPro up and decided to FSD v14.2.1 in the snow. Roads were not compacted like the other day, a little slippery, but overall doable at lower speeds. Enjoy the video and holiday music 🎶

Moving into the winter months, it will be very interesting to see how FSD handles even more concerning conditions, especially with black ice, freezing rain and snow mix, and other things that happen during colder conditions.
We are excited to test it ourselves, but I am waiting for heavy snowfall to make it to Pennsylvania so I can truly push it to the limit.

Tesla hosts Rome Mayor for first Italian FSD Supervised road demo
The event marked the first time an Italian mayor tested the advanced driver-assistance system in person in Rome’s urban streets.
Tesla definitely seems to be actively engaging European officials on FSD’s capabilities, with the company hosting Rome Mayor Roberto Gualtieri and Mobility Assessor Eugenio Patanè for a hands-on road demonstration.
The event marked the first time an Italian mayor tested the advanced driver-assistance system in person in Rome’s urban streets. This comes amid Tesla’s push for FSD’s EU regulatory approvals in the coming year.
Rome officials experience FSD Supervised
Tesla conducted the demo using a Model 3 equipped with Full Self-Driving (Supervised), tackling typical Roman traffic including complex intersections, roundabouts, pedestrian crossings and mixed users like cars, bikes and scooters.
The system showcased AI-based assisted driving, prioritizing safety while maintaining flow. FSD also handled overtakes and lane decisions, though with constant driver supervision.
Investor Andrea Stroppa detailed the event on X, noting the system’s potential to reduce severe collision risks by up to seven times compared to traditional driving, based on Tesla’s data from billions of global fleet miles. The session highlighted FSD’s role as an assistance tool in its Supervised form, not a replacement, with the driver fully responsible at all times.
Path to European rollout
Tesla has logged over 1 million kilometers of testing across 17 European countries, including Italy, to refine FSD for local conditions. The fact that Rome officials personally tested FSD Supervised bodes well for the program’s approval, as it suggests that key individuals are closely watching Tesla’s efforts and innovations.
Assessor Patanè also highlighted the administration’s interest in technologies that boost road safety and urban travel quality, viewing them as aids for both private and public transport while respecting rules.
Replies on X urged involving Italy’s Transport Ministry to speed approvals, with one user noting, “Great idea to involve the mayor! It would be necessary to involve components of the Ministry of Transport and the government as soon as possible: it’s they who can accelerate the approval of FSD in Italy.”
