Car interiors are drawing significant attention of the customers. With ever growing competition, balancing cost & weight with enhanced quality has become a challenge, especially when designing for low cost cars. Car interiors must appear in excellent condition, to maintain good resale value. Particularly, carpet should not look worn out / abraded. Used-car buyers will assume that if the carpet looks worn, rest of car is worn. The objective of the present work is to analyze the effect of material specifications & process variables on the abrasion performance of the needle punch non woven carpet with optimization of cost, weight & appearance.

The Interior noise is now one of the signatures of passenger vehicles. It contributes significantly to a customer's perception of quality. The vehicle acoustic package can be an important piece to the acoustic signature, and can be used not only to reduce sound level inside the vehicle but also to shape the sound such that it meets the expectation of customer and increasing competition between the Vehicle Manufacturers. The conflicting objective of maintaining high Noise, Vibration and Harshness (NVH) characteristics at the same time reducing the weight of the vehicle is a major priority within the Automotive Industry. Moreover to meet ever-growing demand to minimize emission and to achieve greater efficiency from automobiles, there has been a constant effort to reduce the weight of the vehicle body structure along with improving NVH of vehicle.

Vehicle hood experiences impact loading once it is dropped freely from a specific height. This phenomenon is known as Hood Slam (HS). HS induces damage to the components of the hood and front end module. This damage accumulates over the vehicle lifetime and may lead to failure. In a traditional design process, the durability performance of the hood and front end module is evaluated by conducting an impact test. It is, however, very costly and time-consuming to achieve a statistical-based confidence. This paper presents the CAE methodology that intends to replace the physical test and predict the durability performance of the hood and front end module early in the design cycle. The precise capturing of the time dependent contact conditions between the different components of the closing mechanism is essential in simulating the load transfer between the hood and the body.

Nowadays much greater emphasis is given on improving the NVH Performance of an automobile due to global move of customer satisfaction. Noise is an irritant to a valued customer - customer expects value for money in all perspective. There are many sources for noise generation in a vehicle. Noise due to pulsating fuel flow is one of the major causes. The pressure pulsation from the fuel supply system (generated by the sudden opening & closing of the injectors result in pulses inside rail, Low Pressure or High Pressure pump pulses, sudden cross section changes in flow path, etc) can cause an undesirable noise which may propagate as fluid or structure borne noise in to the cabin room, therefore in a conventional engine, a pulsation damper is usually mounted on the fuel rail to diminish the undesirable noise. However, the pulsation dampers are quite expensive. Therefore, several studies have focused on reducing fuel pressure pulsation by various methodologies.
