How does a dirty air filter affect fuel efficiency in a Tesla Model 3

- The search results focus on the effects of dirty air filters in internal combustion engine vehicles, but do not indicate these same issues apply to electric vehicles like the Tesla Model 3.

- In traditional gas-powered cars, a clogged air filter can restrict airflow to the engine, reducing performance and fuel efficiency. However, this is not directly relevant to an electric vehicle's powertrain.

- The cabin air filter in the Tesla Model 3 is designed to filter air entering the cabin, not the air flowing through the electric motor and battery system. A dirty cabin air filter would not impact the efficiency of the electric drivetrain.

- The Tesla Owner's Manual [3] states the cabin air filter's purpose is to "prevent pollen, industrial fallout, road dust and other particles from entering the cabin through the vents." It does not mention any effects on range or efficiency.

- The Tesla Shop website [5] also only discusses the cabin air filter in terms of maintaining interior air quality, without any references to impacts on the vehicle's electric powertrain performance.

In summary, the search results do not indicate that a dirty cabin air filter would have any measurable effect on the overall efficiency or driving range of a Tesla Model 3. The cabin air filter is designed to improve passenger comfort, not to affect the electric motor and battery system that determine the vehicle's energy consumption and range. Regular filter replacement is recommended, but primarily for maintaining good air quality inside the cabin.
