**Abstract:** The objective of this research is to develop a suitable chassis dynamometer to test new vehicles for compliance with emission standards for type-approval in Pakistan. There is a lack of facilities and protocols for testing new passenger vehicles to measure vehicle exhaust gas emissions. This study is performed to fill this gap and might help local authorities in the implementation of exhaust emission test procedures. Assessment of exhaust emissions can be performed by placing the vehicle over the chassis dynamometer. An air-cooled eddy current dynamometer is selected for this purpose. The road load equation is used to simulate the real-life performance of a vehicle while driving at different speeds.

**Keywords:** chassis dynamometer; emission regulations; European type-approval
