How many parts (screws and bolts included) does the average car have?

The correct answer and explanation is:

The average car has around 30,000 to 40,000 parts, including screws, bolts, and other components. This includes both major parts like the engine and transmission, as well as smaller components such as screws, fasteners, and electrical connectors. The exact number can vary depending on the make and model of the car, as well as its complexity.

These parts are generally categorized into several systems. Some of the main systems include:

1. Engine and Transmission: These are often the most complex parts of a car, consisting of thousands of components. The engine alone might have thousands of moving parts, including pistons, valves, and camshafts.
2. Body and Chassis: The body includes everything from the exterior shell, doors, and windows to the frame and underbody components. These parts are often made from steel, aluminum, or composite materials and are held together with hundreds of fasteners.
3. Electrical and Electronics: Modern cars contain an extensive array of electrical and electronic systems. This includes everything from the battery and alternator to sensors, wiring harnesses, and infotainment systems. With advanced technologies like autonomous driving features and smart sensors, the number of electronic components in cars has surged.
4. Suspension and Steering: The suspension system includes parts like springs, shock absorbers, and control arms, while the steering system involves components like the steering wheel, rack and pinion, and various linkages.
5. Interior: The interior features include seats, dashboard components, airbags, climate control systems, and more. These are often fastened together with various screws and bolts.

In addition, each component may have its own subcomponents, such as washers, bolts, and nuts, which contribute to the total count of parts in a car. Over time, as technology has advanced, cars have become more complex, which has led to an increase in the number of parts needed for manufacturing and assembly.
