Tesla’s forthcoming hardware 4.0 computer reveals that Tesla will be able to connect up 12 cameras with its new FSD hardware suite, up from the current nine it uses today.
Earlier this week, Tesla owner and hacker Greentheonly leaked information and pictures of Tesla’s anticipated hardware 4.0. Green confirmed some big and subtle improvements to the hardware.
12 Cameras in Hardware 4
The new hardware's main board will accept up to 12 cameras, with one of them labeled as a spare. Tesla currently uses nine cameras in its current hardware and is expected to reduce the front-facing cameras by one. Based on this information and the labels on the camera connectors, it appears that Tesla will include three additional cameras with FSD hardware 4.0.
When Greentheonly revealed these hardware 4 details, Twitter user StayLameBro1 inquired about where the new cameras will be placed around the vehicle. “There are seemingly 3 bumper cameras,” Green responds. “One up front the other two are left and right so in the corners somewhere.”
Green adds that the addition of bumper cameras and HD radar will remove blind spots. This is a big deal alone. Lastly, Green added that these additional cameras could allow Tesla to incorporate a real bird’s eye view into its vehicles, a feature many Tesla owners have been requesting.
Bird’s Eye View
Bird's eye view is a feature that many other automakers have had for a while now, including Toyota, Honda, BMW, and Lucid. It allows for drivers to see a top-down view of their vehicle and surroundings, increasing safety and spatial awareness.
Last fall, Tesla announced they’re transitioning their fleet to their own Tesla Vision. The company added that vehicles built in October 2022 and beyond would no longer include ultrasonic sensors (USS). This sent confusion around the Tesla community given the blind spots, but hardware 4 will seemingly address these concerns.
The removal of the USS saves Tesla approximately $114 per vehicle. This is in line with “Project Highland,” a cost-cutting project for the upcoming revamped Model 3.
No Retrofits for Hardware 4
One big improvement that’s coming to hardware 4 are upgraded cameras. Currently, Tesla uses cameras with 1.2-megapixels. Hardware 4 is expected to ship with 5-megapixel cameras. However, Tesla owners on hardware 3 will not be able to retrofit their vehicles.
Tesla CEO Elon Musk told investors that upgrading hardware 3 to hardware 4 is difficult and expensive.
“The cost and difficulty of retrofitting hardware 3 with hardware 4 is quite significant,” Musk said. “So, it would not be, I think, economically feasible to do so.”
After the leak of hardware 4, we now begin to understand Musk's statement. We're not only talking about a new computer with hardware 4, but higher-resolution cameras, additional cameras, possibly a new bumper design and an HD radar unit.
Musk has also reiterated that hardware 3 will be capable of driving safer than a human, however, it's not clear under which constraints that would be, such as specific roads and weather conditions, or whether a human driver would always be required to be attentive.
Update: We have now confirmed that FSD Hardware 4.0 will not include additional cameras in the bumper or elsewhere, which means that the vehicle will still have a blind spot. However, we have been told that the 'bumper' camera connectors on HW4.0 are for future expansion, but will not be used initially.
