Tesla hacker and Twitter user @greentheonly has speculated that it won’t be possible to retrofit current MCU 2 (Media Control Unit) Teslas employing Intel chips with the new and improved Ryzen-based processor that is used in MCU 3.

In an up-close inspection of a new Model Y’s internals Green stated that “retrofit for intel cars definitely looks impossible - totally different power and other harness and thickness of the unit.”

The news hasn’t been confirmed nor denied by Tesla or its CEO, Elon Musk, but if proven to be accurate it would most certainly disappoint a great number of MCU2 vehicles owners, who were expecting to be offered the possibility of an upgrade, in the same way current MCU1 owners are able to upgrade their chips for a $2,000 (plus tax) fee.

MCU (Media Control Unit) is the computer controlling Tesla’s touchscreen, processors, RAM (short term memory), non-volatile memory (long-term memory), the audio subsystem, 5 amplifiers, WiFi, Cellular, Bluetooth, GPS, the Ethernet bridge, multiple CAN bus communications, the LIN bus, USB ports and many more.

It handles every software operation, excluding Full Self-Driving/Autopilot, which are unaffected by which MCU version a Tesla is equipped with. All Tesla’s built after November 2016 are capable of Full Self-Driving.

MCU2 came out in the spring of 2018 (fall of 2017 for Model 3) as an upgrade to the NVIDIA’s Tegra 3 processor found in MCU1. All cars delivered after that point benefited from the improved responsiveness and extra features that came with the Intel’s Atom E8000 Series CPU.

From a technical standpoint, the two chips possessed entirely different architectures. The release of software update V10 highlighted the differences, as MCU1 owners were excluded from both Tesla Theater and Tesla Arcade. Effectively, MCU1 doesn’t support Netflix, Hulu, YouTube, or any other streaming services that may be added in the future. It also doesn’t support any of the games Tesla added. Additionally, the web browser on MCU2 is much quicker and more capable as it’s built on Google’s Chromium platform.

In summer of 2021 Tesla released the redesigned Model S with a more powerful infotainment processor MCU. At the time no one was sure whether this was Tesla's next generation MCU or whether it would trickle down to other models.

Then in late 2021 the first news of a new Tesla MCU chip generation started to flood the web, with reports coming from China of a new AMD Ryzen-based computer being present in newly delivered Model Y’s.

The new MCU is faster and brings noticeable improvements in responsiveness in the web browser, as well as while using video streaming services, such as Netflix and YouTube.

Tesla Semi to have 500 mile range, to be delivered this year

Tesla's first electric semi-truck will have a range of 500 miles and begin shipping this year, according to a tweet from Elon Musk, founder and CEO. Musk previously said that the model would be on roads in 2023, as well as Tesla's pickup truck, dubbed the Cybertruck. The projected arrival date for the Cybertruck has not changed.

The Tesla Semi Truck, which was unveiled in November 2017, is designed for long-haul trucking. It can go from 0 to 60 mph in 20 seconds when hauling a full load, which is faster than most diesel trucks.

The Tesla Semi Truck's range of 500 miles on a single charge constitutes more than double the range of the current longest-range electric truck on the market, the Daimler eCascadia, which has a range of 230 miles.

The Tesla Semi Truck is also significantly cheaper to operate than a diesel truck, Tesla has said. The company estimates that it will cost $1.26 per mile to operate the Tesla Semi, compared to $1.51 per mile for a diesel truck.

Since the company started taking orders for the truck in 2017 some of the most sizable orders have come from the likes of UPS, Walmart, and PepsiCo. The original deposit required with an order was $5,000, which was increased to $20,000 after the event in November 2017.

The company has not said how many trucks it plans to produce but based on past statements from Tesla we can expect the price of regular production versions for the 300-mile (480 km) and 500-mile (800 km) range versions to be $150,000 and $180,000 USD respectively.

Tesla's Semi Truck is part of the company's push to electrify the transportation sector, which is responsible for a significant portion of greenhouse gas emissions. Tesla also makes electric cars and SUVs, and it plans to start producing its electric truck next year. Tesla's ultimate goal is to transition the world to sustainable energy.

Teslas to report real-time data to help with road closures and traffic issues

Future Feature

Tesla may be building out a feature for vehicle-to-vehicle communication

Tesla recently wrapped up its 2022 annual shareholders meeting, and CEO Elon Musk hinted at a potentially exciting feature coming to the fleet: vehicle-to-vehicle communication.

Towards the end of the shareholders’ meeting, a gentleman in the audience mentioned how aircrafts use a system called Airborne Collision Avoidance System (ACAS). He elaborated on how ACAS relays an aircraft’s telemetry to prevent a collision.

“Sometimes too much telemetry,” Musk adds and laughs, assumingly referencing the Twitter account that tracks his private jet.

“Do you see Teslas communicating with one another and Dojo turning into some kind of air traffic control for Tesla supply chains and Robotaxi?” adds the gentleman.

Musk answered by saying he hasn’t thought about that before, which is interesting. He added that the goal with Dojo is to be the de facto computer for training the neural net with videos.

“Oh. That’s an interesting idea. I haven’t thought about that,” Musk responds. “Right now our goal with Dojo is to be really good at video training. We have probably the fourth or approaching the third, most powerful computing center in the world for AI training. Our first goal with Dojo is to make it competitive and be more effective at neural net training than a whole bunch of GPUs. We might get there… soonish.”

Musk also added that Dojo is built “from the ground up” to train AI using videos, and building such a computer has never been done before.

This question got Musk’s mind going. He paused for a moment and said there may be some difficulties in getting Teslas to communicate with one another - and it won’t be needed with Full Self-Driving.

“There will be some merits for Teslas to communicate [with] each other, but that won’t be needed for Full Self-Driving at all,” Musk responds. “But for a long time the vast majority of cars will be manually driven, so the value of Tesla-to-Tesla communication is not that high, except for, perhaps, communicating traffic issues, accidents, potholes, and road closures. A Tesla ahead of you has seen a road closure and you get that real-time update to your car so you don’t get stuck in the road closure situation. That’s the stuff that we are working on right now.”

Elon Musk's Answer

In January of 2022, Twitter user and Tesla enthusiast @BLKMDL3 tweeted at Musk asking about this type of feature. “Hey @elonmusk, can we get the air suspension in Model S/X to automatically raise quickly if the car detects a dip in the road ahead and then remember the location for next time?” BLKMDL3 writes. “Would be an awesome feature to have!”

Musk responded with, “Yeah.”

BLKMDL3’s tweet received quite a bit of attention.

Tesla has recently rolled out updates to improve a vehicle’s ability to raise and lower its suspension when arriving at a specific location. This is so the vehicle doesn’t scuff the pavement and cause damage to its underbody.

Since Musk stated that he hasn’t thought about vehicle-to-vehicle communication or how it would be done, we don’t anticipate this feature rolling out anytime soon. However, we can hope that it gets added to the pipeline of upcoming features due to its seemingly positive reception and want for it. This could also increase the safety of Tesla’s vehicles, even though they’re already the safest cars on the road.

It would be nice for vehicles within a 5-10 mile radius to notify one another of a construction zone, or accident, similar to Waze. This would allow the vehicle to reroute to a more efficient route or handle the situation accordingly. Going a step further, it would be exceptionally cool to see snapshots or videos of the upcoming situation by seeing a “hotspot” in maps, similar to how Snapchat shows hotspots, that are recorded via the vehicle’s cameras to more accurately prepare for it. But this may open a can of worms in regards to privacy.

Turning Tesla’s fleet into a mobile social network may go against Musk’s vision. He’s stated before that any user input in the vehicle should be considered an error, so having an interactive feature such as this may not be in Tesla’s deck of cards.
