In vehicle dynamics, how does mounting a rooftop luggage box affect vehicle handling and fuel consumption?
Answer and explanation
Correct answer: A. Raises center of gravity, increases aerodynamic drag and fuel use, and increases sensitivity to side crosswinds
- Step 1: Under Macedonian Road Traffic Safety Law (ZBSP), Roof boxes raise vehicle mass centers and amplify wind resistance, worsening stability and economy. Answer: Raises center of gravity, increases aerodynamic drag and fuel use, and increases sensitivity to side crosswinds. Why not the others: Lowers vehicle aerodynamic drag and cuts fuel consumption does not represent the statutory standard under Macedonian vehicle safety rules.
