Tesla's Model Y With Hardware 4.0 Doesn't Include Radar: We Take a Look at Why

Tesla's Model Y with HW4 is coming without radar

Tesla

As Tesla continues to redefine the automotive industry, insiders have revealed that the company's upcoming Hardware 4.0 (HW4) will not include the radar module in its Model Y vehicles, at least not initially. This marks a shift in the company's approach towards autonomous driving, relying more heavily on vision-based systems. This strategic decision builds on the recent introduction of HW4 in the luxury Model S and Model X models.

HW4 Evolution and Vision Focus:

Previously, the integration of HD radar in the Model S and Model X indicated an evolution in the company's Full Self-Driving (FSD) hardware. However, according to a trusted source, Tesla is not including HD radar in its new Model Ys with HW4. This surprising decision could mean several things, possibly indicating that Tesla views HD radar as a "ground truth" to help improve their vision systems rather than a vital component for FSD vehicles.

Ground-truth Radar: A Tool for Vision Improvement:

In this sense, ground truth refers to the objective reality or facts of a situation, typically used as a benchmark to measure the accuracy of an AI system's predictions or observations.

Last year, Tesla registered a new high-resolution radar unit with the U.S. Federal Communications Commission (FCC), a move that sparked speculation about the company's approach to FSD. The radar unit, intended for imaging similar to LiDAR, hinted at Tesla's continuing interest in using ground-truth systems to train their machine-learning algorithms for vision accuracy. Despite Elon Musk's well-documented skepticism towards LiDAR for autonomous driving, Tesla prototypes have been spotted with LiDAR sensors.

HD Radar to be Added Later?

Although Tesla may be using its radar in HW4 vehicles to improve their vision system, other possibilities could have led Tesla to this decision. New Model Ys with HW4 may only be without radar temporarily, possibly due to a supply chain issue. New owners would still better off receiving a vehicle with HW4 and without radar than a HW3-equipped vehicle due to the improved cameras and faster FSD computer that includes redundancy.

Cost Savings

Of course, HD radar inclusion could also come down to cost. With the Model Y costing almost half of Tesla's luxury models, this decision could come down to cost. If Tesla believes their FSD system could perform almost identically to vehicles with radar, they may simply decide to forego the radio technology in lower-cost vehicles.

Balancing Vision and Radar: The Trade-Off:

While HD radar and LiDAR can provide highly accurate 3D depth measurements, their high cost and potential to overwhelm the FSD system with conflicting data have led Tesla to prioritize camera-based vision systems. Musk has consistently argued that self-driving cars should navigate the world in the same manner as human drivers, using cameras and computational power to navigate three-dimensional space.

Model Y With HW4 But Without HD Radar:

While excluding HD radar from the HW4 in Model Y might seem like a setback, it could prove to be a game-changer. Tesla's strategy of using radar to enhance vision rather than as a core component of its FSD system means that these vehicles may not be as disadvantaged as initially thought.

This approach is consistent with Tesla's earlier decision to remove ultrasonic sensors from some vehicles, enabling them to run vision-based park assist code and compare vision readings to ultrasonic sensor readings. This resulted in significant improvements in vision detection, further solidifying Tesla's commitment to a vision-oriented future.

Introducing HW4 into the Model Y may suggest Tesla's potential future strategies. For instance, commercial Robotaxis may employ multi-sensor systems, including radar and possibly LiDAR, to achieve full automation. Conversely, consumer self-driving vehicles could maintain the vision-only approach to keep costs down.

Ultimately, the transition to HW4 indicates Tesla's unwavering pursuit of refining autonomous driving technology. As the landscape of self-driving vehicles continues to evolve, it will be interesting to see how Tesla's approach shapes the future of this sector.

Tesla Officially Launches the New Model 3 Performance, Deliveries Start Next Month

Today, a few hours before releasing their first quarter financial results, Tesla launched the highly anticipated Model 3 Performance. The new version starts at $45,490 (after applying the $7,500 Federal EV tax credit) and deliveries are scheduled to start in May.

With 510 horsepower and a top speed of 163 mph, the new Performance variant brings an improved sound system, a re-designed interior featuring more comfortable rear seats with some features coming directly from the recently revamped Model 3. Tesla also says that the new Performance model has “significantly less” road and wind noise thanks to the rear spoiler and changes to the front bumper.

“The front and rear fascias, rear diffuser and carbon fiber spoiler work together to help reduce drag and improve lift balance at high speeds”

Tesla’s most powerful Model 3 ever is now cheaper than the Model 3 Long Range after the federal tax credit. The Model 3 Performance model is the only Model 3 variant that is eligible for the government incentive.

Tesla Cuts Newly Formed Content and Ads Team, Musk says Ads Were “Too Generic”

Tesla eliminated a newly formed marketing team of about 40 employees as part of its global layoffs, Bloomberg reported on Monday morning. On X, Elon Musk said the ads created by the team were “far too generic” adding that they would apply to “any car”.

Exactly. The ads were far too generic – could’ve been any car.

— Elon Musk (@elonmusk) April 22, 2024

The team was led by Alexander Ingram who joined Tesla in August 2019 as Communication lead for Automotive. After a few different roles connected with content and social media, Ingram was promoted last December to Senior Manager of Global Growth Content. In the new role, he was leading a global team of creatives focused on Tesla's first ads, as well as social media.

Ingram put out some excellent behind-the-scenes videos on Tesla’s technological advancements such as the one below explaining Tesla’s single casting.

Tesla’s Advertisement Strategy

At Tesla’s 2023 annual meeting of shareholders, Elon Musk said that the company would “try a little advertising and see how it goes”. Since then, Tesla ads have been seen in Google search results and on YouTube.

In Tesla’s proxy statement filed last week, it is seen that the automaker has spent around $200,000 on X-advertising through February 2024.

“As part of a multi-platform advertising campaign, Tesla also directly or indirectly purchased advertising on X, which totaled approximately $0.2 million through February 2024”

Bloomberg’s source added that Tesla still has a smaller marketing team in Europe.
