A detailed study is performed on a Nissan Juke to evaluate the influence of applied body reinforcements on the vehicle dynamic performance and how this can be linked to the drivers' subjective perception. Evaluation of the vehicle body during the Experimental Modal Analysis indicates body stiffness increases (both global body stiffness as local connection point stiffness) as an effect of the applied body reinforcements. The impact of these body stiffness increases is a changed body load distribution during vehicle dynamic manoeuvres. These identified changes in objective quantities match the subjective perception of the expert driver: Increased Front Subframe Lateral loads - which are composed of the Steering Rack and Lower arm Lateral loads. The driver indicated an improvement of the steering effort linearity. Increased Front Strut Lateral loads; together with the changed Subframe Lateral and Vertical loads this impacts the vehicle roll behaviour. Also this is mentioned by the expert driver.
