Can the drag coefficient of the Model 3 Performance be improved through software updates

The search results indicate that the Tesla Model 3 Performance already has a relatively low drag coefficient of 0.219, which is the lowest of any Tesla vehicle. This was achieved through careful aerodynamic design, including:

- A streamlined front bumper
- Smaller headlights
- A flatter hood
- Aerodynamic improvements to the rear, such as a redesigned lower rear bumper with an air diffuser

To further reduce the drag coefficient, physical modifications to the vehicle's exterior would be required, such as:

- Adding aerodynamic body kits, like front lips and rear spoilers
- Removing side mirrors (if legally allowed)
- Lowering the ride height

The search results show that aftermarket companies like Unplugged Performance have been able to reduce the Model 3's drag coefficient by up to 0.049 through a combination of these physical modifications.

However, the search results do not indicate that Tesla has the ability to significantly improve the Model 3 Performance's drag coefficient through software updates alone. The aerodynamic properties of the vehicle are primarily determined by its physical design and cannot be altered solely through software changes.

In summary, while Tesla may be able to make minor software-based adjustments to optimize energy efficiency, the drag coefficient of the Model 3 Performance is fundamentally limited by its physical design and would require hardware modifications to achieve substantial improvements.
