*)WHY A HOOD? Hood is one of the most important component of a vehicle when it comes to safety and design. It is considered as the 6th door including the passenger 4 doors, back lid, fuel tank door. In design it makes the car look stylish. In aerodynamic terms, hood is the component which directs the air flowing over it…

1) Every part that is designed and developed has to qualify not only in terms of aerodynamics but strength too. For aerodynamics, the design can be customized and reshaped for better air flow over the surface of the that panel. In the same way, the design also plays a key role in giving strength to the material. Of…

Fender is a fibre/plastic component which shields the wheels and restricts mud,water,stones etc that gets carried along the rotating grooved tyre. The grooves are deliberately cut on the tyres so as to provide a smooth path for the road substances to get channelled out resulting in better traction. The substances tend…
