Ikshit Shrivastava1, Kiranpreet Singh2 1,2 International Centre for Automotive Technology (ICAT), Gurugram, India Introduction: Pass By Noise emitted by the vehicle is one of the most critical tests for certification is vehicle worldwide. There are a number of national and international regulations to define test procedure. Though the available tracks are constructed to meet the requirements of these test standards, but there are other external parameters viz. ambient temperature, barometric pressure, wind speed and its direction, affecting the measurements. These parameters are beyond the control of human and this contamination of test data results in longer test time to monitor atmospheric/ambient conditions and perform the test. Indoor pass-by noise testing is a comparatively new method of testing, which is yet to be evaluated for repeatability/correlation with conventional exterior pass-by noise testing.

Until 2017, the pollutant emissions and fuel consumption Type Approval (TA) procedure for light duty vehicles in Europe was based on the New European Driving Cycle (NEDC), a test cycle performed on a chassis dynamometer. However several studies highlighted significant discrepancies in terms of CO2 emissions between the TA test and the real world, due to the limited representativeness of the actual test procedure. Therefore, the European authorities decided to introduce a new, up-to date, test procedure capable to closer represent real world driving conditions, called Worldwide Harmonized Light Vehicles Test Procedure (WLTP). This work aims to analyse the effects of the new WLTP on vehicle CO2 emissions through both experimental and simulation investigations on two different Euro 5 vehicles, a petrol and a diesel car, representatives of average European passenger cars.
