Visual Inspection: Examining Tesla’s Hardware
While software updates can significantly impact a Tesla’s capabilities, physically identifying the hardware version (HW3 or HW4) requires a closer look. Tesla doesn’t readily advertise the specific hardware installed, so you’ll need to rely on visual cues and careful examination.
1. Focusing on the Front
The most prominent hardware difference lies in the forward-facing cameras. Tesla vehicles equipped with HW3 typically feature a single front-facing camera mounted above the Tesla logo on the windshield.
In contrast, HW4 models sport a distinctive arrangement of two front-facing cameras. These cameras are positioned slightly offset from the center, flanking the Tesla logo on either side.
Example: A Tesla Model 3 with HW3 would have one camera centered above the Tesla logo. A Model 3 with HW4 would have two cameras flanking the logo.
2. The Side Cameras: A Subtle Clue
Another clue lies in the placement of the side cameras. HW3 Teslas typically have side cameras mounted lower on the side mirrors, closer to the vehicle’s body.
HW4 models tend to have side cameras positioned higher on the side mirrors, closer to the top edge. This difference in positioning can be subtle, so careful observation is needed.
3. Unveiling the Sensors: A Closer Look
For a more definitive identification, you can examine the sensors located along the underside of the vehicle. HW4 models typically incorporate a more extensive array of sensors compared to HW3 models.
While specific sensor configurations may vary depending on the model year and trim level, HW4 vehicles generally feature additional ultrasonic sensors, radar sensors, and potentially LiDAR sensors.
