Tesla's new hardware 4.0 is close, but don't expect retrofits
Tesla
Tesla's upcoming FSD hardware, hardware 4.0, is nearing completion, and although there is limited information about it, it sounds like it'll bring significant improvements. It's yet to be known when the new hardware will debut, but it is clear Tesla will not be retrofitting the existing fleet.
"The cost and difficulty of retrofitting hardware 3 with Hardware 4 is quite significant. So, it would not be, I think, economically feasible to do so."
Musk said Hardware 3 is five years old but, "is still the most efficient inference computer in the world."
What Will Be In Hardware 4.0
It's believed that the new hardware will use 5-megapixel cameras; the current cameras are 1.2 megapixels. Also, some leaked pictures appear to reduce the amount of front-facing cameras from three to two and allow for heaters and fans.
The higher-resolution cameras will give Autopilot a significant advantage when trying to determine objects that are further away because of the additional pixels. An object that is 100 or 200 feet away may only be made up of a few pixels, but with almost 5x the resolution, the newer cameras will be able to more accurately determine what the object is. This is also true for everything else, such as the curvature of the upcoming turn.
In addition to the cameras, we know that there will be a new FSD computer which is expected to be about 4x more powerful than the current FSD computer in hardware 3.0. Part of this additional processing power will no doubt go toward processing the additional 32 million pixels that the newer cameras will provide.
However, hardware 4.0 will be about more than just a faster computer and better cameras. It is also expected to include an HD radar, which Elon Musk has talked about in the past and has been seen in Tesla's FCC filings. The addition of a high-definition radar could provide a significant advantage to FSD by sensing objects that cameras alone can't.

When Musk talks about the upgrade from hardware 3.0 to hardware 4.0 not being feasible, that likely means there may be even more to it than we already know. This could just be due to the new radar, new power, or space requirements for the new computer, but it's also possible that there could be more to hardware 4.0 than we know.
We know that Tesla's Robotaxi is already in development and this is a vehicle that is expected to be completely driverless. Tesla won't have the convenience of having a driver behind the wheel here. This could mean that Tesla may need to add additional hardware that we haven't heard about it. This could be different camera placements, or something entirely different.
What we know for sure is that hardware 4.0 will include higher-res cameras, a faster computer and likely an HD radar, but there could be even more that makes it infeasible to retrofit older vehicles.
Elon Talking About Hardware 4
The video below is queued up to the part where Elon talks about FSD hardware 4.0 (segment begins at 30:10).
Hardware 3.0 Will Be Capable of FSD
Musk put the argument into perspective for those who may want to wait. "Hardware 3 will not be as good as Hardware 4, but I'm confident that Hardware 3 will so far exceed the average -- the safety of the average human." He then broke it down further, "let's say, for argument's sake, if Hardware 3 can be, say, 200% or 300% safer than human, Hardware 4 might be 500% or 600%." In fact, stats show that Teslas operating with Autopilot engaged at 10 times safer, and that is with Hardware 3.
Will Teslas With HW3 Really Be Autonomous?
Listening to Musk's choice of words is interesting, he seems to have steered away from words he may have used in the past, such as referring to level 5 autonomy, or using the words robotaxi, or autonomous driving. Instead, he chose to say hardware 3 would exceed the safety of an average human. That could mean that Tesla's current FSD implementation will always require a driver behind the wheel, but the combo of Tesla's FSD system and the driver as a backup would be multiple times safer than a human.
Tesla has to be Careful
The CEO had a tightrope to walk when talking about the existing hardware and what the future system will look like. You may recall in late 2022 when demand for Teslas started to slow down. Many observers believe it was due to the impending tax credits the Inflation Reduction Act would provide for buyers of electric vehicles. Tesla cut prices for the last few days of 2022 to match tax credits, but only for consumers who took delivery before the end of the year.
Now, a new dilemma, how many consumers will wait for the latest hardware? There is no timeline for it, the only vehicle we know it will be in is the Cybertruck, but the Cybertruck won't start production until this summer.
FSD Hardware 5.0
Musk has a point. Hardware 3 is fantastic, but with a new one that is twice as good on the horizon, it losses some exceptionality. Then there is this next line by Musk, "with Hardware 4 coming and then Hardware 5 beyond that where there are significant leaps." So yes, we already have talk of Hardware 5. However, this is not expected for several years.
Once again, mark your calendar for March 1, 2023. Tesla is hosting Investor Day, and along with more information on the next-generation vehicle, we may get more details on hardware 4.0 and what it will contain.

Tesla’s Model Y has held the title of the world’s best-selling vehicle—across all categories—for the past three years. And it takes an absolute masterstroke of engineering and design to make an even better, more popular vehicle.
In a newly released video (posted below), Tesla highlights some of the key upgrades and refinements made to the Model Y. While a previous deep dive explored the engineering details [insert link here], this latest video offers a broader look at the improvements. Let’s take a closer look.
Unique Design of the Model Y
The refreshed Model Y is all about individuality. While every Tesla model stands out in its own way, some are more similar than others. For example, the Model S and Model X share a similar front fascia design but still feel distinct. The previous Model 3 and Model Y, however, were often difficult to differentiate, even for seasoned Tesla owners.
That’s no longer the case. With the refreshed Model 3 and Model Y, the differences are clear enough to make each vehicle instantly recognizable. You’ll easily spot them on the road and distinguish them from their predecessors.
Design
The lightbar is the first thing you’ll notice about the design overhaul. Tesla aimed to give the vehicle a wider, more grounded appearance while also creating more space on the front fascia. This newfound space not only improves the vehicle’s look but also leads to some efficiency gains—more on that later.
The rear lightbar is equally striking. It’s a reflective, full-body design, marking a first in the automotive industry. The light is reflected onto a custom applique, which directs it downward, creating a puddle of red light behind the car. As Franz, Tesla’s Head of Design puts it, it gives the impression of an afterburner.

Ride Comfort
Tesla has been focused on improving ride comfort, and the refreshed Model Y is a testament to that effort. While the original Model Y had more of a sports car-like handling, which was less ideal for family use, the new suspension design focuses on comfort by reducing impact harshness, all while maintaining Tesla’s signature steering feel and precise handling.
This is paired with in-house designed tires, developed alongside the tire manufacturer, resulting in the most efficient EV tires Tesla has ever used. With lower rolling resistance, improved handling, and reduced road noise, these tires contribute to a smoother, quieter ride.
The addition of acoustic glass across every glass surface in the vehicle, combined with upgraded sealing materials throughout the cabin and body, has led to a 20% reduction in overall vehicle noise. This is a substantial improvement for an already quiet EV.
The new silver-infused acoustic glass also reflects heat much more effectively than the older glass, reducing the strain on the vehicle’s climate system. This allows the fan to run at a lower speed, further reducing cabin noise and improving energy efficiency. Tesla has truly pulled out all the stops to make the refreshed Model Y one of the most comfortable and refined passenger vehicles on the road.
Efficiency and EPA Range
When it comes to efficiency, Tesla has meticulously reevaluated every component and design choice of the original Model Y, all while maintaining the same size and form factor that has made it a favorite for millions worldwide. The result? A 10% improvement in efficiency over the previous Model Y, which translates to more range.
The EPA recently announced the official range for the vehicle of 327 miles, beating Tesla’s estimate of 320 miles. This is an increase of 16 miles over the outgoing AWD Model Y, which had an EPA estimated range of 311 miles.
The front ducts have been widened thanks to changes in the front fascia, allowing for improved airflow over the tires and front brakes. Meanwhile, the new thermoplastic spoiler has been redesigned at the rear to be more aerodynamically efficient, contributing to the overall 10% efficiency boost. These updates improve performance and range.
Utility
The Model Y has become the ubiquitous Sports Utility Vehicle, capable of handling just about anything. In addition to improving its performance and efficiency, Tesla has also improved its practicality. The trunk opening has been enlarged, making it easier to load and unload items.
One standout feature is the power-folding rear seats. With just the push of a button, you can effortlessly fold them down or raise them back up. Additionally, the front seats automatically slide forward to create more space when you need to bring the rear seats down.
Tesla also gave the frunk a thoughtful upgrade. It now includes a new drain plug, and the bottom liner is fully waterproof—an improvement over the previous water-resistant version. This means you can fill the frunk with ice or use Tesla’s upcoming frunk cooler without worry. There’s even talk of more accessories on the horizon, and we can’t wait to see what Tesla has in store for this versatile space.
Safety
Safety has always been a top priority in Tesla’s vehicle design, and the Model Y has consistently earned 5-star crash safety ratings worldwide. It’s expected that the refreshed Model Y will continue this trend, maintaining Tesla's reputation for top-tier safety.
Additionally, the new front bumper camera offers valuable assistance for parking in tight spaces or when navigating off-road. While there’s no official word yet on whether these bumper cameras will be integrated into Full Self-Driving (FSD) or Smart Summon for the refreshed Model Y or Cybertruck, it’s definitely something to watch for in future updates.

Front and rear infotainment
Not a Tesla App
Inside the refreshed Model Y, Tesla has fine-tuned every detail to create a more premium feel. This includes the addition of ambient lighting, similar to the refreshed Model 3 and Cybertruck, as well as new materials throughout the cabin to elevate the overall aesthetic.
The redesigned heated and ventilated seats take comfort and support to the next level, which is a significant improvement for those who use the Model Y as their daily commuter. A comfortable seat can make all the difference on long drives.
In the rear, the updated infotainment system can now pair with two Bluetooth headsets specifically for the back screen. This means passengers in the rear can enjoy audio independently of the front, so if your kids want to watch cartoons, you can continue enjoying music or the news without any interruptions.
Tesla also developed new acoustically transparent materials, which are used to conceal some of the 16 speakers and the newly positioned microphones. Placing the microphones closer to the driver and front passenger’s heads improves clarity for voice recognition and phone calls.
Be sure to check out the full video below to see the meticulous design work and thoughtful improvements that went into the refreshed Model Y—it’s definitely worth a watch.
Tesla has officially launched FSD in Mexico. This is the third expansion of FSD since it was first launched in the United States.
The news was shared by Tesla Owners Mexico on X, followed by confirmation from Tesla AI with a simple but exciting message: "¡Hola México!"
FSD features are geo-fenced, meaning that if a vehicle equipped with FSD crosses into a country where the software isn’t supported, it will automatically revert back to Autopilot. This expansion has likely lifted the restriction, meaning the U.S. Tesla owners should now be able to drive into Mexico and continue using FSD without interruption.
FSD Global Expansion Timeline
Tesla has set some lofty goals for itself, announcing in their FSD roadmap that it expects FSD to be ready to roll out internationally in Q1 and expand to right-hand drive markets in Q2. While it’s not clear whether Tesla still expects to meet these targets, this is the latest information that was shared in September 2024:
Q1 2025: FSD is expected to launch in Europe and China, pending regulatory approval.
Q2 2025: FSD rollout for right-hand drive (RHD) markets, with a flexible timeline based on approval processes.
Tesla has faced regulatory hurdles, particularly in China, where FSD testing was recently put on hold. One major hurdle is China’s strict data regulations, which require all training data to be collected and stored within the country. This means Tesla cannot rely on its existing U.S.-based data centers and must build local infrastructure to comply with government policies that prevent vehicle data from leaving China.
Additionally, since FSD relies heavily on fleet data, Tesla won’t be able to leverage its vast global dataset. Instead, the company will need to retrain its AI models using data exclusively gathered from vehicles operating within China. These constraints add complexity to Tesla’s FSD rollout, potentially delaying its expansion in the region.
After initially launching FSD Beta in the U.S. to a small group of influencers, Tesla expanded access to more users through its Safety Score program in late 2021. At first, only those with a perfect score of 100 were eligible, but as FSD improved and Tesla grew more confident in its performance, the requirement was gradually lowered.
In March 2022, Tesla took its first step beyond the U.S. by introducing FSD in Canada with the release of v10.11.1. Since then, Tesla has expanded FSD to Puerto Rico, and now, the launch in Mexico marks another major expansion of the software.
This news will likely raise excitement among users outside of North America who have been waiting for FSD for years. With regulatory hurdles in China presenting unique challenges, Tesla may shift its focus to expanding FSD in Europe and Oceania first.
Meanwhile, Tesla also focuses on launching its Robotaxi network, set to debut in Austin, Texas, in June. The upcoming Cybercabs in Austin could be running early builds of FSD v14 or a specialized version designed for Unsupervised FSD.
Like so many other things happening at Tesla right now, it’s an exciting time as Tesla prepares Unsupervised FSD for the Cybercab, continues the expansion of FSD, and works out all the details of its robotaxi network, such as the cleaning hubs and wirelessly charging capabilities.
