In a recent series of fascinating tweets, @greentheonly provided an unprecedented look into the internals of Tesla's new Model Y Hardware 4 or HW4. With his expertise and knowledge, Green shared detailed observations on the HW4's physical structure, board components, and the viability of retrofitting older models, giving the Tesla community much to ponder.

Breaking Down the HW4's Structure

Green's exploration of the HW4's complexities commenced with him acknowledging an "anonymous donor" for providing a chance to look inside Model Y's HW4. The serial numbers and other identifiers were blacked out. Green stated it was done to protect the donor after previous experiences, "Tesla is vengeful like this and went after the guy that did hw2.0 teardown by trying to deny warranty on unrelated repairs. Does not help that this new computer now has a (borderline illegal) 'warranty void if removed' sticker."

Delving into HW4's Core: Circuitry and Components

First up on the dissection table was the computer's physical form factor. According to Green, the HW4's form factor mirrors those of the S/X models, putting to bed any speculation around a potential retrofit to HW3 cars.

Moving deeper into the HW4, Green revealed that the board layout is similar to the HW4 on the Model S. However, as Green termed it, specific components, including the GPU and superior sound hardware, are now missing or depopulated. The use of cheaper non-Error-Correcting Code ram (ECC RAM) also seems to be a cost-cutting measure implemented by Tesla in this version of HW4 on the infotainment system side. Interestingly, this version of HW4 features two additional but depopulated display connectors, hinting at possible a possible second display in the vehicle.

Other distinguishing attributes of HW4 include a reoriented BroadR-Reach ethernet and the addition of a third, depopulated ethernet. Moreover, Green pointed out that the gateway chip has changed, too, with a different model from another vendor now in use. This chip, which was only seen in Chinese-made boards previously, seems to be a standard feature in all Model Y HW4 boards now.

Retrofitting HW3 to HW4: More Than Meets the Eye

The idea of retrofitting HW3 cars with HW4 stirred up quite a debate. According to Green, the concept may sound enticing, but it's not as straightforward as it seems. Modifying the vehicle to accommodate the new coolant pipe locations would be necessary for a retrofit, likely making this option more costly than simply manufacturing a new board in the old form factor.

Uncovering the Hidden Changes

Apart from the apparent changes, Green shared insights into some of the subtle modifications made by Tesla. For instance, the Texas-manufactured Model Ys feature a plastic "firewall" requiring a change in mounting methods for the new HW4. Despite the internal components remaining the same, the different mounting technique necessitates a unique part number for the computer.

Other changes include the absence of premium features like ECC RAM and the HD radar, which is reserved for the S/X models. Also, there's a reduction in the camera connectors in the Model Y, contributing to the list of differences in the HW4.

The missing camera connectors were for additional cameras, such as a front bumper camera. However, as Green says, the absence of a connector doesn't mean that Tesla won't add them in the future. In fact, if Tesla had no intentions of adding such features, they wouldn't be available on the board at all, instead of just being unpopulated.

Implications for Current and Prospective Tesla Owners

For existing and future Tesla owners, these findings offer a clearer understanding of what to expect from the HW4-equipped Model Ys. Notably, questions still linger about additional cameras and if and when newer models will receive them. The Cybertruck prototype already has a front bumper camera, so it may only be a matter of time.

While it seems that retrofitting HW3 to HW4 may not be feasible due to the cost and complexity involved, Green isn't entirely ruling out the possibility. He believes a different version could theoretically be created for retrofits, although it's unlikely.

Elon Musk stood in the back of a Cybertruck with the words behind him: more utility than a truck. Faster than a sports car. Tesla's CEO then backed up that statement for the next 20 minutes with real-world examples.

The presentation showed a Cybertruck out pull an F350 and other competitors. A video demonstrated the Cybertruck beating a Porsche 911 on the quarter mile - the Cybertruck was also hauling a Porsche 911. Of course, the bullet tests video was on screen, with a slow-motion shot of a bullet bouncing off the stainless steel.

The delivery event mostly exceeded expectations, as the stainless steel beast is now on the road. Let's dive a little deeper into some of the unprecedented functionality and cutting-edge technology Cybertruck offers.

Biggest Breakthroughs: Steer-By-Wire System

One of the most talked-about features is the Cybertruck's steer-by-wire system. This advanced technology eliminates the need for a mechanical connection between the steering wheel and the wheels, offering precision control and a new level of driving experience.

Its implementation is a game-changer, providing drivers with enhanced maneuverability and a turning radius that rivals most sedans. Elon Musk compared it to a jet fighter, stating if you steer the yoke just a little in a parking lot, the vehicle can turn a lot, but if you steer the yoke on the highway, it will adapt to the speed and maneuver the truck accordingly.

Bi-Directional Charging

We hoped this one was coming. One of the Cybertruck's most innovative features is bi-directional charging. This capability allows the Cybertruck to charge its own batteries and power external devices and even other electric vehicles. Whether it's powering tools at a construction site or providing emergency power during a grid outage, the Cybertruck doubles as a mobile power station.

Cybertruck Battery

Tesla has put its largest-ever battery into the Cybertruck. The Cybertruck isn't a light vehicle, coming in at 6,603 lbs for the AWD version and 6,843 lbs (3,103 kg) for Cyberbeast, so the fact that it includes Tesla's largest battery isn't surprising.

The AWD and Cyberbeast versions of the Cybertruck both contain a new 123kWh battery. This battery uses 4680 cells and is the equivalent of more than 9 Powerwalls. If you're planning to use the Cybertruck for backup power for your home, there's a lot to like here.

Powered Frunk

The Cybertruck will be the first Tesla to include a powered frunk. It seems that you'll not only be able to open the frunk, but also close it from within the vehicle or through the Tesla app. The spacious trunk also doubles as a bench seat for two for tailgating, sporting events or camping.

Bed Lining

To go along with the power station Cybertruck's super-tough composite bed doesn't require a liner, setting a new standard in durability. This feature is designed to handle all sorts of cargo without worrying about scratches or dents, reflecting Tesla's commitment to both utility and longevity.

Theater on Wheels

The Cybertruck is designed to offer an unparalleled in-vehicle entertainment experience. Its recording studio sound dynamics featuring 15 speakers, including two dedicated subwoofers and distributed amplifiers, transforms into a mobile theater, delivering an immersive audio experience.

At the heart of the Cybertruck's interior are the massive 18.5" touchscreen in the front and the 9.4" touchscreen in the back, both boasting an all-new user interface. These screens are more than just displays; they're control centers that put a wide range of functions at the fingertips of both the driver and passengers.

In line with Tesla's focus on safety and health, the Cybertruck comes equipped with a built-in hospital-grade HEPA filter and Bioweapon Defense Mode, providing protection against 99.97% of airborne particles. This feature, known as the Bioweapon Defense Mode, ensures that the cabin air is clean and safe, regardless of external conditions.

Adventure-Ready

With a range of up to 340 miles on a single charge and the capability to recover up to 136 miles with just 15 minutes of supercharging, the Cybertruck is ready for any adventure. The electronically adaptive air suspension further enhances its off-road capabilities, offering up to 17" of clearance.

Price and Specs Overview

The Cybertruck is offered in three trim levels: the Tri-Motor "Cyberbeast" at $99,990, the Dual-Motor All-Wheel-Drive at $79,990, and the Rear-Wheel-Drive at $60,990. Each model promises a blend of power, efficiency, and range that sets a new benchmark in the electric truck segment.

Tesla has previously stated that it will produce 200,000 Cybertrucks a year. With well over a million reservations, many people could wait a long time to get this vehicle. With that in mind, Tesla offers $1,000 off any other model when customers buy a Cybertruck but take delivery of a different Tesla before December 31.
