What does the term 'base model' mean in cars?

[DeArthur]

Base model refers to the low-configuration version of a car. Generally, vehicles come in standard, low, medium, and high configurations, which respectively mean: 1. Low configuration: Usually means simplified configuration, lacking features like leather seats, power windows, and many electronic control functions; 2. Standard configuration: Includes basic electric controls such as power windows, power steering, air conditioning, etc.; 3. Medium configuration: Slightly more advanced than the standard, including all standard features plus possibly additional airbags, sunroof, leather seats, power seats, seat heating, etc.; 4. High configuration: Higher than all the above configurations, often considered the flagship version of the model.
