LightWeight Engineering- Car

Reducing 10% weight of a car can improve its fuel efficiency of about 10%, and reduce 8% of CO2 production.
Removing 100 Kg from a car can save 0.3-0.6 kg of fuel per kilometer.

Lightweight Engineering has always been an important issue in Aviation applications.  However, due to the shortage of energy, its importance becomes apparent for any fuel-consuming vehicles.
