Technician A says that manufacturers use foam to strengthen and reinforce some pillars. Technician B says the aerodynamics of a vehicle will not affect how fuel efficient it is. Who is correct?

Question

Quizplus · Accepted Answer

Technician A is correct because manufacturers do indeed use foam to strengthen and reinforce some pillars in vehicles, adding rigidity and improving safety without significantly increasing weight. Technician B is incorrect because the aerodynamics of a vehicle significantly affect its fuel efficiency; better aerodynamics reduce air resistance, thereby improving fuel economy.
