Noise is one of the most important parameter that influences the artificial and especially automotive pollution. Developing new motor vehicles, widely known as cars, respectively their auxiliary systems is now difficult to be done without considering noise, vibration and harshness (N.V.H.) aspects in testing and operation. N.V.H. criteria facilitate the appreciation made by testers, owners and users in relation with vehicle’s general behaviour and also in correlation with their auxiliary systems. Main objective of the present paper is to outline the innovative and advanced method in computer aided testing of N.V.H. parameters in a sporty car Porsche Cayman model at Technical University from ClujNapoca. Redefining the standards in comfort and tuning is close related to the N.V.H. research. These parameters are not acting as isolated factors in some isolated environment. They should be considered in relation with the complex whole which is the operating motor vehicle in the road traffic environment. Experimental testing results were achieved and properly analysed and interpreted. There were outlined some trend lines in each case. Development possibilities and perspectives were also pointed out in order to facilitate and encourage the further research of the specific problems.
