- Streamlining the vehicle’s shape can reduce drag by minimizing airflow turbulence.
2. Describe the various methods used to reduce weight in fuel-efficient automobiles.
Lightweight Materials
- Using lightweight materials such as aluminum and carbon fiber.
- Optimizing the panel thickness and structural components.
Weight Distribution
- Distributing weight evenly to reduce inertia and improve efficiency.
- Using high-strength steel in critical areas for weight-bearing.
3. How do you approach the design of a fuel-efficient powertrain system?
To design a fuel-efficient powertrain system, I follow these steps:
- Analyze vehicle performance requirements and fuel efficiency targets.
