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 Is Now Offering Cybertruck Test Drives [List of Locations]

@brandonhd

Tesla has begun to reach out to customers in the United States and is offering demo drives of the Cybertruck on an invite-only basis. @brandonhd on X shared the first invite image, and it looks like it's going out quite quickly to multiple locations that have Cybertrucks on display.

Up until now, display vehicles have been for just that – looking, but no touching. Some Tesla delivery centers and showrooms have also allowed viewers to take a seat inside and open it up, but most are still locked away behind the velvet rope.

It’s exciting to see that Tesla has begun to demo them – and it can only be so long until demo drives open up to everyone.

Advisor-led Demo

This Demo Drive is led by a Tesla Advisor – while you’re driving, the advisor will be in the passenger seat, walking you through the experience. They’ll explain steer-by-wire, off-road controls, and will introduce new-to-Tesla buyers to all the features that are currently available.

Once FSD V12.5 comes to the Cybertruck, we’re sure they’ll be demoing its capabilities FSD capabilities as well.

Locations

The list of locations so far for demo drives appears to be fairly limited, but we will hopefully see demo drives roll out throughout the United States, and eventually Canada too. Here is the current list of city/state locations that have seen demo drive invites.

• Manhasset, New York

• West Covina, California

• Los Angeles, California

• Houston, Texas

• Orlando, Florida

• Westmont, Illinois

• Tucson, Arizona

• Phoenix, Arizona

• Delaware

Musk Confirms 'Actually Smart Summon' is Coming in a Revision of FSD V12.5

Not a Tesla App

Actually Smart Summon, the successor to Tesla’s Smart Summon feature, has been confirmed to be coming as soon as next month as per Elon Musk. Colloquially known as “ASS”, Actually Smart Summon is supposed to improve on the regular Smart Summon capabilities, which have historically used ultrasonic sensors (USS) to navigate parking lots.

We’re looking forward to Actually Smart Summon, and we’re quite excited about what other features will be unlocked once it finally shows up at our doorstep.

Vision-based Improvements

ASS is supposed to bring Smart Summon to vehicles that don’t have USS – using Tesla Vision. Most recently, Tesla has brought Autopark to vehicles without USS, and Vision-based Autopark has been a huge success. It is faster, more reliable, and smoother than the older USS-based solution. It can also park and maneuver in tighter locations.

Just recently, Tesla returned the Model X’s self-presenting doors, using Tesla Vision. Vision has seen some fantastic improvements, and many people are waiting for ASS to bring forth these improvements to Smart Summon.

Smart Summon Today

Today, Smart Summon is sometimes useful at best, usually a party trick, or downright dangerous at worst. It’s excellent and best used in straight lines, where you have a clear line of sight of the vehicle, and can stop it if doesn’t see an obstacle.

I used Smart Summon today, just before writing this article – my 2022 Model Y (with USS) – did manage to show up just fine – in a straight-line location from where I was parked, after exiting the parking spot fairly cleanly. However, I’ve previously used Smart Summon and have had the vehicle turn towards obstacles, such as cart returns or curbs. Overall, it’s a sometimes-useful feature that has a lot of drawbacks right now.

Smart Summon is also restricted to a certain distance – and it's pretty small. The max distance is shorter than most parking lots, being only about 215 ft (65m). If you’re lucky enough to park close, it's very useful to bring your car right to you.

Actually Smart Summon

ASS will bring FSD V12-like capabilities to Smart Summon – the vehicle will primarily use Vision to drive toward you (or the location you’ve indicated). ASS has been supposed to be coming since about September 2022 and has seen many delays – we’re almost at the 2-year point today.

We’re looking forward to Actually Smart Summon being able to bring the vehicle – safely – right to you. ASS is also one of the key steps towards bringing some other cool features that Elon Musk has previously mentioned – Park Seek and Banish Autopark.

We’re also hopeful that Actually Smart Summon will increase the maximum range a vehicle can be summoned, because the current range is fairly small. Alongside Park Seek and Banish Autopark, we’re closing in on a Robotaxi-based future.

Park Seek and Banish Autopark

When the FSD v12.4 showed up, Elon also mentioned that going forward, vehicles would automatically park themselves when arriving in a parking lot – Park Seek – and that if you got out of the car at the entrance to a business, you could get it to automatically park itself in the parking lot – Banish Autopark. These are two features that are needed for Robotaxi to work – which itself is delayed to October 10^th of this year. We’re looking quite forward to them – as in combination with Actually Smart Summon, Tesla has reached the cusp of vehicle autonomy.

A vehicle that arrives, driverless, at the location you’re at, then drives somewhere, parks itself there, and waits for you – is the definition of a Robotaxi.

While we’re likely to have to wait for Banish Autopark and Park Seek just a bit longer, Actually Smart Summon being around the corner is exciting! Gone will be the days of having to run out to your car when you forgot your umbrella – your car will just come right to you instead.
