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.

A Trip Down Memory Lane: The Electrifying Rivalry Between Elon Musk and Jeremy Clarkson [Video]

The automotive world has witnessed many rivalries throughout history, but none quite as electrifying as the ongoing feud between Tesla CEO Elon Musk and British television presenter Jeremy Clarkson. These two larger-than-life personalities have consistently butted heads over electric vehicles, Tesla's performance, and the future of transportation. Let's take a trip down memory lane and relive some of the most memorable moments from this epic battle of wits and opinions.

The Spark That Ignited the Feud

It all began in 2008, when Clarkson, then a host of the popular British television show Top Gear, reviewed Tesla's first production car (video below), the Roadster. In Season 12, Episode 7, Clarkson was critical of the Roadster's range and reliability, with the segment featuring the car running out of battery and breaking down. Tesla quickly claimed that the breakdown was staged for dramatic effect, a claim that BBC denied.

The Aftermath and Legal Action

Tesla didn't take Clarkson's review lightly. In 2011, the electric car manufacturer filed a lawsuit against BBC, alleging defamation and malicious falsehood. However, the British High Court dismissed the case in 2013, with the judge stating that no Top Gear viewer would have reasonably compared the Roadster's performance to that of a traditional sports car based on the episode.

The War of Words

The legal battle didn't put an end to the rivalry. Over the years, Musk and Clarkson exchanged barbs through interviews and social media. In a 2018 interview with The Independent, Clarkson called Musk "an idiot" and claimed they "almost had a fight." In response, Musk took to Twitter and called Clarkson "weird" and "rude." In 2021, Clarkson talked about Musk's kids' unique names and suggested he call them "John or Jane or whatever."

The Twitter Battle

The rivalry between Musk and Clarkson has expanded beyond the realm of electric vehicles. Recently, Clarkson shared his thoughts on Musk's new Twitter laws and claimed that the new CEO should be paying him to use the social media network. In his Sunday Times column, Clarkson expressed his outrage at the proposed new costs for blue tick verification. He argued that he brings in advertising for the platform and should not be paying for the verification. This latest episode showcases the enduring feud between these two influential figures.

The Autopilot Debate

Clarkson has also criticized Tesla's Autopilot feature, questioning its safety and reliability. He once called it "an accident waiting to happen" after a fatal accident involving a Tesla Model S operating on Autopilot in 2016. However, Musk has dismissed Clarkson's concerns as biased and uninformed, insisting that critics have an outdated view of electric vehicles and are resistant to change.

The Model X Review and Beyond

Despite his new-found popularity, Clarkson didn't shy away from critiquing Tesla. In a 2019 episode of The Grand Tour, he reviewed the Tesla Model X, acknowledging its advancements while questioning its design and practicality. Clarkson said, "The truth is, the world's most hated car company has changed the world," but he also questioned whether electric vehicles would ever fully replace internal combustion engine cars.

The Grand Tour and Clarkson's Farm

After leaving Top Gear, Clarkson and co-presenters Richard Hammond and James May launched The Grand Tour on Amazon Studios. The show continued to feature Tesla vehicles and maintain a critical stance on electric cars. However, Clarkson's image softened with the release of his show Clarkson's Farm, which showcased his love for farming and the challenges he faced in running a farm. The show garnered a new fan base and a more sympathetic public image, but he still prefers internal combustion.


In a surprising twist, Elon Musk appeared on Top Gear in 2020, discussing Tesla's progress and the future of electric vehicles with the show's presenters. Though Clarkson was not involved in the episode, the appearance marked a notable moment in the rivalry's history.

The ongoing feud between Elon Musk and Jeremy Clarkson is a fascinating chapter in the automotive world. As electric vehicles become increasingly popular, the rivalry between these two influential figures serves as a reminder of the broader debate surrounding the future of transportation. With the latest development involving Twitter, it's clear that their rivalry continues to evolve and shows no signs of slowing down. Fans of both individuals can only wait and see what the next chapter holds for this electrifying tale.
