The improvements in v12.5 are supposed to focus on rarer, more complex situations and vehicle-to-fleet communication. Tesla’s Autopilot lead, Ashok Elluswamy, also mentioned that FSD would gain the ability to go in reverse around this time.
Merge City & Highway Stacks
FSD v12 has been a multi-stack setup so far, with a city-streets stack that is end-to-end, and an older highway stack that was carried over from v11. FSD v12.5 will once again merge the city/highway stacks according to Musk, who confirmed the feature yesterday. That means that there will no longer be an implicit highway stack.
This could cause some regressions during highway driving, similar to the ones we experienced when Tesla first merged highway and city stacks back in FSD v11. Ultimately, when the issues were ironed out, we ended up with a smoother and better Autopilot experience on the highway. When FSD v12.5 rolls around, we may see some similar issues but expect FSD v12.5 to do to highways what v12 did for city driving.
Vehicle-to-Fleet Communications
Tesla’s FSD relies heavily upon maps, with the mapping information designating routing and lane changes. When vehicles encounter difficulties, they are unable to communicate that back to the rest of the fleet. This results in every vehicle encountering the same problem. With FSD V12.5, vehicles will be able to communicate road closures or other obstacles back to the rest of the fleet in real-time. This will turn FSD into software that’s constantly improving as the fleet gathers more data, instead of having to wait for a software update.
Cybertruck Finally Gets FSD
In a recent post on X, Musk also confirmed that V12.5 will finally bring FSD to the Cybertruck. Currently, all Cybertrucks only have access to Traffic Aware Cruise Control (TACC). Autopilot and FSD capabilities should arrive alongside all the other features.
Actually Smart Summon
Musk has talked quite a bit about Actually Smart Summon. With FSD 12.5, the new vision-based summon may finally be released. This will introduce Smart Summon capabilities to vision-only cars for the first time. However, it’s expected to be a drastic improvement for all vehicles in similar ways to the new Autopark. The new summon has been tied to the ability to move the vehicle in reverse by Tesla’s Autopilot lead, so expect either both of them to arrive in FSD 12.5, or be held off for a later release.
Release Date
Musk originally mentioned that FSD V12.5 would be released in late June, however, there were several delays with FSD 12.4 and that time frame has now come and gone. FSD 12.4 was initially released in May 2024, but it went through several lengthy revisions before it was introduced to public testers. Going by that time frame, it appears that FSD 12.5 was expected to be released about 4-6 weeks after FSD 12.4. If FSD 12.4.3 is finally got a good spot, we could see FSD 12.5 become available in the next 4-6 weeks or about late August.

During a major update presented during the Q2 2025 Earnings Call, Tesla confirmed that its plans for a new, more affordable vehicle are finally on track for sales to begin later this year. Tesla originally stated that production for the more affordable model would begin by the end of the first half of 2025, and they’re technically correct - they’ve begun production, but sales will not begin until late 2025.
Tesla is targeting a production ramp-up throughout Q3 2025, with the vehicle officially going on sale sometime in Q4 2025. To achieve this timeline, Tesla is sticking with what we’ve previously heard about the affordable model. It will likely be a simplified, cut-down version of the ever-popular Model Y, rather than a vehicle built from the ground up on a new platform.
Slower Ramp, Later Launch
While the news of a 2025 launch is exciting, Tesla has cautioned that the production ramp will be slower than initially expected. With the ramp beginning in Q3, Tesla has attributed the slower pace to two key factors: the recent cut of the EV tax credit in the US, and an internal focus on factory retooling.
Let’s break that down. In response to the recent tax credit cut, Tesla has focused its efforts on producing as many of its current vehicles as possible, allowing customers in the United States to purchase vehicles while the tax credit is still active. In order to double down on this, Tesla is running their largest batch of promotions in North America that we’ve ever seen - with a promotion on nearly everything but the new Model S and Model X.
Because of this, their manufacturing lines at Fremont and Giga Texas are running full speed, not allowing time for the retooling needed to produce the affordable model. The affordable model appears to be based on the same platform as the Model 3 and Model Y, as Tesla plans to utilize its existing production facilities to produce the new model.
So, in the simplest of terms, Tesla has been too busy producing vehicles on the very same factory lines that will eventually produce the affordable model. Now, as we enter Q3, Tesla expects to slow down that pace to allow for factory retooling and ramping for the affordable model, for a sales launch in late 2025.
E41: A Pared-Down Model Y
Based on comments from Elon and the team at the Earnings Call, the affordable model will almost certainly be a more cost-effective version based on the existing and proven Model Y. We’ve previously heard rumors about project E41 from China, which told us about a feature-cut Model Y that would come in with a 20% reduction in costs.
The E41 is expected to feature textile seats, similar to those of the cut-down Model 3 for Mexico, while also likely reducing features such as heated and cooled seats, ambient lighting, the rear screen, acoustic glass, and speakers. At the end of the day, E41 isn’t the next-gen, affordable model on a bespoke platform that many have been waiting for—the Tesla Compact. Instead, it’s a simplified and pared-down Model Y that is more affordable for a wider range of potential buyers.
This reduced complexity allows Tesla to bring a lower-cost vehicle to market much more quickly. It is a pragmatic decision that prioritizes getting an affordable, FSD-capable EV into customers' hands sooner. This lets Tesla adapt to current market and economic realities, rather than waiting for a revolutionary but more complex-to-manufacture new platform.
Will There Be a Next-Gen Model?
Tesla still has several plans for new battery cell types and new drivetrains in their plans for 2026 and 2027. In addition, with the new LFP battery production plant in the United States beginning to scale up, there is a good chance that Tesla is still hard at work in their secretive design studio on a newer, smaller, and even more affordable model.
We believe that Tesla still intends to produce a new, smaller model, but given today’s market realities, it doesn’t make sense to introduce an extremely low-margin model into the lineup. This is especially true when new car sales are suffering due to economic uncertainties and tariff obligations are changing daily.
The Next Steps
Now, with what is likely the E41 beginning production ramps at Fremont and Giga Texas, we’ll have to wait to see exactly what Tesla has done to cut down on the Model Y and what they manage to cut the price down to.
With the Model Y RWD coming in at $44,990, a 20% price cut would bring it down to about $35,990 (before incentives), making it by far Tesla’s cheapest EV. That makes it remarkably more affordable, especially for those who still have remaining state incentives in place. By some miracle, if Tesla can bring that price down to $29,990, it may become the best-selling budget vehicle we’ve ever seen. We don’t expect such a drastic price cut until at least the introduction of the next-generation model, though.
We’ll be keeping a close eye on what Tesla does, as if they’re actually producing these vehicles now, it shouldn’t be long before we’re able to spot them.
It’s happening… According to an internal memo viewed by Business Insider, Tesla is expanding its Robotaxi Network to a new city. This expansion will take place in the San Francisco Bay Area and marks the first Robotaxi expansion.
According to Business Insider, this timeline was accelerated following the success of Robotaxi in Austin. Following a discussion with our own source, the rollout is expected to begin on Sunday morning. Interestingly, this timeline lines right up with the conclusion of the X Takeover event in San Mateo, which several Tesla executives are likely attending.
This launch will mark the second city for Tesla’s ride-hailing service, following its debut in Austin. As with Austin, the service will be invite-only for some Tesla owners, who will be able to hail and pay for rides via the Robotaxi app.
What to Expect
For this initial deployment, the Robotaxis will still be deployed with a human safety monitor, but with a catch. Unlike the Austin deployment, where the monitor sits in the passenger seat, the Bay Area monitors will be in the driver’s seat. This is a critical distinction, and for all intents and purposes, a safety driver. This is due to regulatory reasons, which we’ll dive into.
The service will operate within a geofenced area covering a wide swath of the Bay Area. The memo mentions that the area should cover Marin, San Jose, and much of the East Bay area. Tesla will once again be using the modified Model Ys it uses for the Austin Robotaxi Network - equipped with a second telecommunications unit.
We’re expecting Tesla to send out a round of invites in the coming days for owners local to the Bay Area.
Regulatory Grey Area
While the launch is a landmark moment for Tesla, there’s an interesting story behind just how they’re navigating the rollout of Robotaxi, given California’s complex regulatory environment. The presence of a safety monitor in the driver’s seat isn’t a precaution - it is exactly the way Tesla intends to push the deployment until formal federal regulations supersede municipal and state regulations on autonomous vehicles.
According to the California DMV, Tesla has a permit for testing FSD with a safety driver, but has not yet secured a permit for driverless testing or deployment. The California Public Utilities Commission (CPUC), which regulates ride-hailing services, has also not received an application from Tesla for a commercial public service permit as of early July, according to Business Insider.
By keeping a fully capable monitor in the driver’s seat, Tesla appears to be operating in a regulatory grey area. The service could be defined as a “chauffeured ride-hailing service” that uses FSD as an “advanced driver-assist” feature, rather than a fully autonomous service. This allows Tesla to continue operating under its existing testing permits while it continues to work with the DMV and CPUC to obtain approval.
Elon previously mentioned that the Bay Area regulators have been extremely reasonable, so this strategy was likely developed in conjunction with the regulators to start the rollout early and obtain regular permitting as operations continue.
This is definitely a bold first step outside of Austin, and we’re happy to see that Tesla is pushing hard on expanding the Robotaxi Network. This allows Tesla to gather invaluable data on FSD performance in another dense and challenging environment, while also adding more paying customers to its network. Tesla also plans to expand to Florida and Arizona, as well as other US states and cities by the end of 2025, so there will definitely be more to come.
