Tesla Talks FSD Hardware 4.0, but There Will Not Be Retrofits

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.

No Upgrades From FSD Hardware 3.0

Regarding upgrading hardware 3 to hardware 4, Elon Musk told investors:

"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 Launches New Long Range RWD Model Y in U.S.: More Affordable and Longer Range

Not a Tesla App

Tesla has finally launched the refreshed Model Y Long Range Rear Wheel Drive (LR RWD) in the United States. While the refreshed Model Y RWD was available as a Launch-Series option in the Asia-Pacific and European markets, it wasn’t yet available at all in North America. Once the Launch Series stopped being offered, Tesla began shipping non-Launch Edition Model Y LR RWDs in Asia and Europe earlier this year, but didn’t bring it to the United States until now.

The LR RWD is one of Tesla’s most affordable vehicles, starting at $44,990 (or $37,490 after the Federal EV Rebate).

Model Y LR RWD

Spec-wise, the refreshed Model Y LR RWD is a compelling alternative to the AWD model. Tesla has kept the premium interior and audio options on the North American variant, so you get the full experience of the refreshed Model Y. You also get more range and faster charging than the AWD model. The only downside is that it’s two-wheel drive and slower acceleration. However, given the lower price and additional range, those may be worth the tradeoffs.

*Listed ranges are EPA Ranges.

Pricing

All in all, you get a fantastic deal, given the lower price tag. The refreshed Model Y LR RWD is priced $4,000 less than the AWD version while still offering many of its attractive features.

*Post-tariff pricing.

Availability

The Long Range RWD is expected to begin shipping immediately in the United States. Tesla has not made the vehicle available in Mexico or Canada yet, likely due to tariff complications. Once the tariff rates settle, Tesla will likely look to export the vehicles from the U.S. to the other two North American countries.

With the arrival of the Long Range RWD variant, the last version we’re waiting for is the refreshed Model Y Performance. That’s likely to be an exciting vehicle, and we’re hopeful it will be in customers’ garages before the end of 2025.

Tesla Introduces New Dynamic Supercharger Pricing

Not a Tesla App

Tesla is adjusting its Supercharger prices based on current usage in a new pilot program. Tesla’s pricing structure has typically revolved around traditional time-based peak/off-peak schedules but is now migrating to a more dynamic model based on live Supercharger utilization.

This development, announced officially through the Tesla Charging X account, should make Supercharger pricing more accurately reflect the demand for the specific Supercharger site instead of basing pricing on past usage.

Live Utilization Pricing

The core of this new pilot will launch at just 10 Supercharger sites in North America. The particular sites in question have not been clarified, but one of the locations is the Supercharger located in Davis, California.

Tesla intends to expand the pilot based on feedback and the success of the initial rollout. We could be looking at the future of Supercharger pricing around the globe.

New Chart and Features

Today, Tesla typically offers two or three prices based on peak and off-peak demand, meaning that Supercharger prices are based on the hour of the day. The current Supercharger chart in the vehicle shows the hours and price on the X-axis, while the Y-axis is the typical demand (image below).

However, with the new charts that will soon be added to vehicles, Tesla will display the time on the X-axis, and the Y-axis will show the historical demand and the current price (photo at the top of this page).

In theory, the Supercharger's historical demand and real-time usage should be pretty similar, but there will be exceptions, like holidays and other events. Unexpected high and low usage will play a role in the pricing, such as sporting events and natural disasters. If the Supercharger is busy, then pricing will be high; otherwise, it will be low.

This also introduces a new feature, since pricing is now based on actual demand, users could navigate to a Supercharger that is less busy and, therefore, cheaper. In the hero image, we can see that Tesla will add a new “Find Lower Price Charging” button in a future vehicle update. This will likely highlight other nearby Superchargers that are less busy and less expensive.

However, it seems like Tesla may also start charging more for Superchargers than they do today when they’re extremely busy. Judging by the screenshot Tesla shared, the estimated usage never passed the $0.45 per kWh at the Davis, CA Supercharger. However, it seems that there’s a new price of $0.54 per kWh when the Supercharger usage is at its peak.

The good news is that Tesla is being more transparent and indicating whether the price is low or high with new labels. This change will give users more choices in terms of charging prices. If you want to save a few bucks, you can drive to a less busy Supercharger. The price will also be based on actual usage, which seems like a fairer way to determine price.

While Tesla hasn’t updated vehicles yet to show these new charts, the latest version of the Tesla app already incorporates the changes.

What Tesla Says

Max de Zegher, Tesla’s Director of Charging, elaborated on the pilot program on X.

He points out that Tesla Charging’s rates have been consistent, and it has focused on improving the charging experience and availability. Off-peak and on-peak pricing will help to increase both of these.

Tesla has outlined exactly how this new live feedback loop will function. The more accurate real-time station demand can allow Tesla to adjust pricing if a station is experiencing congestion during traditionally “off-peak” hours. On the flipside, if a station is unusually empty, Tesla can reduce the pricing.

This easily incentivizes customers who are keeping an eye on charging costs, as changing your charging destination can be as simple as the tap of a button. Most interestingly, Tesla says that the average price paid by customers is expected to remain the same as with the previous time-based system, even with seasonal and real-time fluctuations.

Crucially, owners can always see the price per kWh on their vehicle’s primary display, as well as in the Tesla app before initiating a charging session. Additionally, Tesla will not change the pricing mid-charge, so there’s no need to worry about it fluctuating up or down while you’re charging.

When reading some of our old blog posts, you'll find that @TeslaCharging has been consistent in its pricing principles: improving the charging experience and Supercharger availability. True to those principles, we're now piloting live site utilization for off-peak and on-peak… https://t.co/rIqQzOZfcG

Supercharger Pricing History

This move to live-based pricing is being presented as Tesla’s latest step towards managing its vast charging network with a more customer-centric approach. Tesla has had some historical progression in its pricing strategy, so let’s take a look at where we were versus where we are going.

kWh-Based Billing: Tesla has long pushed for billing by the kilowatt-hour (kWh) as the fairest method for customers to pay for the exact energy consumed, avoiding session fees that can obscure actual energy costs. This is now standard in most regions, but it wasn’t too long ago that pricing was determined by the minute.

Idle Fees (2017): To address vehicles remaining plugged in after charging was complete at busy sites, idle fees were implemented to improve stall availability – a practice now common across the industry.

80% SoC Limiter (2019): At busy locations, Tesla introduced an automatic 80% state-of-charge (SoC) charging limit (which users can manually override) to encourage faster turnover, as the final 20% of charging is significantly slower.

Time-Based Peak/Off-Peak Pricing (2020): Pricing based on estimated busy times was rolled out to incentivize charging during less congested periods, helping to distribute demand and manage costs.

Congestion Fees (2023): At particularly busy sites, congestion fees were introduced. These combine the principles of idle fees with disincentivizing charging to a very high state of charge when a station is crowded, with the stated goal of improving availability, not generating profit.

Commitment to Affordability

Alongside these pricing changes, Tesla has reiterated its focus on keeping Supercharging affordable for all its users. Tesla points out that, on average, in North America and Europe, Tesla’s Superchargers are 30% cheaper than other fast-charging options while also being far more reliable.

Beyond that, 2025 is set to be Tesla’s largest year for expanding the Supercharger network while also replacing many older V2 charging sites with faster, more capable V4 Supercharger stations.
