Question

Sometimes, in suspension system, instead of standard type of coil springs ............... type of coil springs are used in automobiles.

• A. normal
• B. compact
• C. progressive
• D. soft

Hint:

Tip: Progressive springs = progressive comfort + control!

Answer 1

The Correct Option is C

In modern automobile suspension systems, progressive coil springs are often used instead of standard coil springs.
Progressive springs are designed with variable stiffness — they have tightly wound coils at one end and wider coils at the other.
This design allows the spring rate to increase progressively with compression.
When small bumps are encountered, the softer part absorbs the shock smoothly, providing a comfortable ride.
For larger loads or rough terrain, the stiffer section engages, preventing bottoming out.
This combination improves ride quality and handling compared to standard springs.
Normal, compact, or soft types do not specifically refer to this variable rate design.
Therefore, the answer is progressive.
