What is the difference between broad-sense passenger vehicles and narrow-sense passenger vehicles?

[LeBennett]

The differences between broad-sense passenger vehicles and narrow-sense passenger vehicles are as follows: 1. Micro buses: Micro buses refer to mini passenger vehicles, commonly known as minivans. Minivans typically have small engine displacements, usually no more than 1.5L, and use a mid-engine layout, meaning the engine is located under the seats, with rear-wheel drive. This is because they need to consider load capacity; when going uphill, the center of gravity shifts backward, reducing front-wheel traction, necessitating rear-wheel drive. 2. Commercial buses: If passenger vehicle sales statistics include minivans, their purchasing guidance significance is relatively weak. In reality, modern minivans are more commercially oriented. However, since they have fewer than 9 seats and are passenger vehicles, they are classified as passenger vehicles. To distinguish them from traditional passenger vehicles, they are categorized under broad-sense passenger vehicles. Passenger vehicles with 9 seats or fewer, excluding minivans, are all classified as narrow-sense passenger vehicles.
