The mass monitoring of assembled vehicles is mandatory to understand if the current production vehicles is in accordance with the already certificated mass and in agreement with Inovar-Auto, Rota 2030 requirements and support vehicle development special the chassis components sizing and vehicle dynamics performance. It is important to highlight that a great part of that measurements happens on the field in a not ideal condition.However, must be a natural deviation of the measured masses due to environmental influences, as the height differences between scale pads for each vehicle corner. Once that a height difference must be impact the vehicle measured mass distribution it is necessary to understand these influences on the measurements results.The objective of this paper is to measure the sensitivity of vehicle weight reaction measurements by corner due to height variation on each corner and conclude if this can affect the audit of mass performed by regulatory institutions and or internal audit that provides data to engineering.For this study will be considered weight measurements per corner for a passenger car varying its heights and considering its mass, inertias, suspension mechanisms and stiffness modeled in multibody environment (CAE tool).
