    Ferrari is known for its superior design in aerodynamics by Pininfarina which is demonstrated by 360, 430 and 458 without a (movable) rear wing like Porsche.

    The rear "wing" in Ferraris is integrated so well into the car's rear body, you would not notice it if not paying attention and the benefit of not having a separate or movable wing is weight saving and less mechanical parts to go wrong.

    I am wondering whether it means that the body line of Porsche is not as effective and efficient as Ferrari's in creating enough downforce and so Porsche has to rely on rear wings (911 w/ movable wings and GT2/3 w/ fixed but much larger separate wings) to generate the needed downforce?

    A 911 with its engine position has not enough space in the rear for an effective diffusor. Additionally Porsche is using the rear wing for cooling reasons.

    Not a beautiful solution but an effective one. ;)

    My guess is that Pinninfarina had little to do with the underbody aerodynamics--which is where the lack of spoiler and wing on modern F-cars come from.

    As I understand it, PF does a ton of aero work for Ferrari street cars.

    Daniel has it right about the 911 shape. Its a classic but its not the most aerodynamic one.

    The Classic 911 profile is darn near a wing profile. Lots of lift. The raise able rear spoiler cuts lift like the flaps on a plane landing.

    If they had wind tunnels and or aerodynamic engineers involved in the 356 and early 911 shapes, it wouldn't look like it does now.

    They also likely never imagined the this 911 shape cruising at 150+ mph and having drivers complain about "light rear end" in corners :)
