pedestrian safery regulations
Automakers are being held to pedestrian safety legislation which is created to protect in a frontal collision.
The pedestrians body cannot deform the hood in an impact such that they strike a hard-point below (like the engine).
Cowl heights are being raised to allow for the crush zone mandated by the legislation.
The reason we don't see 'racing' cooling systems on passenger cars may have something to do with things which have nothing to do with efficiency.
