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 Begins Testing FSD in China

Tesla was recently granted permission to test FSD on Chinese streets – specifically in Shanghai. Just recently, Elon Musk visited China and discussed the potential for FSD to come to China.

Gearing Up for FSD China

This is just the first step for Tesla to begin its customer deployments of FSD – Tesla conducts similar ADAS testing in North America, where special testing vehicles and testing employees run the latest FSD (Supervised) versions against a gamut of real-world, real-life tests.

Tesla has recently been working on translating FSD release notes into multiple languages, alongside building a data center in Shanghai and establishing an FSD Operations and Labelling team at the same center. These are the first, key steps to bringing FSD to a new market that has unique and different traffic rules when compared North America.

China doesn’t have the regulatory hurdles or challenges that Tesla faces in Europe to bring FSD and has been working with Chinese corporations as well as the government, which has now provided its official approval for FSD testing in-country.

We might even see FSD deployed to early testing customers in China by the end of 2025.

ADAS Competitors

There are quite a few competitors in the Chinese market already- with challengers like Xpeng and Xiaomi working on building their own homegrown systems, mostly driven by a mixture of cameras, radars, ultrasonic sensors, and LIDAR. However, many of these systems face similar challenges to other non-Chinese competitors and don’t have the mileage under their belts to tackle Tesla’s dominating lead in data and data processing.

European Union

Tesla is poising itself for an FSD rollout internationally, with increased testing also taking place in the UK, France, and Spain – some of the key locations with unique infrastructure in the European Union. However, some EU-specific regulations restrict how FSD can perform – each and every action must be manually approved by the driver. Until that regulation is changed to adapt to systems like FSD, it won’t be making its way there just yet.

Tesla Cybertruck to Receive Charging Improvements in Upcoming Update

Former Tesla VP of Powertrain and Energy Drew Baglino previously mentioned that Cybertruck would be receiving charging improvements soon.

Wes Morrill, Tesla’s Cybertruck lead engineer, recently reposted Baglino’s comments on the charge speed update on June 16th and mentioned that it would be coming soon via OTA.

Charging Improvements

The 4680 cell has seen some difficulties in its charge curve, similar to Tesla’s other vehicles that have been deployed with the 4680. Tesla has alluded to difficulties in the manufacturing curve previously, and also with engineering improvements to the new cell standard, and eventually stopped manufacturing the Model Y with the 4680 cells.

However, this is the first time that Tesla has begun to deploy major improvements to the 4680 cell. It appears the improvements will allow up to 154 miles to be recovered in 15 minutes, which is approximately a 30% improvement to current charge rates.

We’re hoping that these improvements to the 4680 will also translate to older Model Y vehicles that have 4680 cells, which will be key to the owners of these vehicles. 4680 production is currently mainly focused on Powerwall, Megapack, and Cybertruck – with Semi not using 4680 yet.
