Improvements of Hardware 4 compared to Hardware 3
- Camera technologyAI4 has high-resolution cameras that enable better detail recognition. The front cameras have a resolution of 2896x1876 pixels compared to 1280x960 pixels in Hardware 3.
- Computing powerAccording to Elon Musk, AI4 is about 3-5 times faster than Hardware 3, which enables more efficient processing of data for autonomous driving.
- Design changesAI4 uses new electrical and wiring harnesses that ensure improved cooling and stability of the hardware.
How to check your Tesla hardware version
It is important to know which hardware version your Tesla has, especially if you are using FSD (Full Self-Driving) or use a subscription. Here are some simple ways to switch between Hardware 3 and Hardware 4 (AI4) must be distinguished:

- Front camerasAI4 has two red lenses and one black (fake) lens, while Hardware 3 has three black lenses.
- Repeater camerasThe repeater cameras of AI4 are also equipped with a red tint and narrower indicators.
3. vehicle software and display
Unfortunately the Tesla-app or the vehicle itself does not directly indicate which hardware version is installed. Therefore, the physical and purchase-related indications mentioned above are the most reliable.
No retrofitting to hardware 4 possible
Elon Musk and Tesla have confirmed that a retrofit from Hardware 3 to Hardware 4 is not planned. The new cable and cooling systems of AI4 make a simple retrofit impossible. Instead, optimized Tesla the software continues to optimize for Hardware 3 to maximize the performance of FSD functions.
Conclusion
The distinction between Tesla Hardware 4 (AI4) and Hardware 3 is for Tesla-owners to understand and utilize the power of the driver assistance systems. With the improved cameras and increased processing power, AI4 offers a significantly improved driving experience. If you have a new Tesla-vehicle or already own one, it's worth checking the hardware version to get the most out of your FSD-functions.
