To categorize the parts of a car from the most general to the most specific, you could use the following list:
- Vehicle
- Automobile
- Car
- Vehicle Body
- Chassis
- Engine
- Transmission
- Suspension
- Brakes
- Tires
- Battery
- Exhaust System
- Interior Components (seats, dashboard, etc.)
- Specific Engine Parts (pistons, camshaft, etc.)
- Specific Transmission Parts (gears, clutch, etc.)
This hierarchy starts with the broadest term (vehicle) and narrows down to specific parts.
