Body 9115 Aerodynamics and air ducting The emphasis of the aerodynamic optimisation is at the front end. The modification allows for improved wind flow around the front of the vehicle which also produces a 15 percent increase in cooling air flow. The side nose section radii and wheel arches forward of the front wheels are designed so that the front wheel side walls are optimally screened from the wind achieving much improved wheel arch ventilation. The modification package as a whole results in a reduction of front wheel lift coeffi- cient from CAV = 0.08 to CAV = 0.06 and rear axle wheel lift coefficient from CAV = 0.05 to CAV = 0.03. The drag coefficient remains unchanged at CW = 0.30 (cW x A = 0.58, frontal area A = 1.94 m2 5_05_02 5 - 2 Service Information 2002
