The Making of Fuel-efficient Car By Arjun Agrawal. Introduction I want to explore ways to increase fuel-efficiency of the car to reduce the environmental impact. When cars drive most of the energy is wasted in heat and only 30% of energy is used to move the car. There are several ways in which cars can be made fuel-efficient including reducing weight, increasing aerodynamics, changing the type of fuel, fast refueling, finding energy dense batteries, reducing battery degradation, and reducing the cost of battery materials. Weight Cars are made of metals such as steel that are heavy to be strong and hard. This makes the car protect the human being from getting hurt in an accident. But the weight of the car takes more energy to push it forward making the car fuel inefficient. We have to use lighter materials that are strong. There are the following materials we can use: · Aluminum: Aluminum is reasonably strong and light. Aluminum ...
