Without fanfare, Tesla has introduced their most refined self-driving computer, Hardware 4.0 (HW4), into the Model Y lineup. It's a surprising move, as it was believed HW4 would roll out with the Model Y redesign. This strategic decision, executed in Tesla’s unique, understated style, follows the quiet integration of HW4 into the luxury Model S and Model X models earlier this year.
This shift came to light thanks to one of our sources, who has provided accurate information in the past. Tesla owner Zack (@BLKMDL3) has now identified multiple Model Y units equipped with fresh hardware at his local delivery center. The distinctive upgraded side repeater and forward-facing cameras indicate HW4 were observed in both Long Range and Performance variants of the Model Y.
Transitioning to the New Standard
Notwithstanding these exciting sightings, numerous Model Ys with the previous hardware was still found at the delivery site. As is customary with Tesla’s approach to hardware rollouts, the full switch to HW4 across all Model Ys will take some time as Tesla factories incorporate these changes.
Source code information connected to a recently manufactured Model Y also confirmed the presence of HW4, designated as "AP HW4". Interestingly, this phased implementation might lead to disparities among Model Y units depending on their manufacturing origin. For instance, those made in China, where no HW4 incorporation has been reported yet, might cause Canadian customers to miss out on the HW4 upgrade.
HW4: Paving the Way for Enhanced Autonomy
Tesla’s HW4 represents the company’s commitment to refine its vision-based self-driving system further, shifting from the previous reliance on a combination of vision and radar sensors. It plays a pivotal role in Tesla’s bold objective to master Full Self-Driving (FSD) by year-end.
Nonetheless, it's worth noting that certain functionalities were not instantly available during the early stages of HW4 deployment. This factor likely played a role in Tesla's decision to delay its introduction of the Model Y. As Tesla continues perfecting HW4, further enhancements are anticipated, including improved handling of complicated maneuvers, such as unprotected turns.

The Hardware Evolution: Comparing HW4 and HW3
Insightful images shared by the Tesla community have provided a comparative look between HW4 and its predecessor, Hardware 3.0 (HW3). Of note, the side repeater cameras on the Model Y with HW4 have noticeably larger lens housings and a wider field of view. This departs from early anticipations, which projected HW4 would introduce additional cameras. Instead, the updated hardware seems to enhance the existing camera system.
What Lies Ahead
The introduction of HW4 into the Model Y marks a remarkable stride in Tesla's commitment to perfecting Full Self-Driving technology. As Tesla continues to develop and refine HW4, it's exciting to envision the transformative potential this holds for the automotive landscape.
While Tesla CEO Elon Musk’s ambitious vision of a Robotaxi fleet may still be some way off, the integration of HW4 in the Model Y undeniably represents a key milestone in that journey. As this revolutionary technology evolves, the world eagerly awaits the exciting advancements it promises to bring to the autonomous driving experience.

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.
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.
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.
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 10th 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.
