According to engineers of rival teams, the higher rear end of the Red Bull artificially adds volume to the diffuser, hence makes it "think" it's bigger than it really is.
With the cannon exhausts on the side acting a bit like side fences and enclosing the volume of the diffuser more efficiently, Red Bull loses the disadvantage of more air rushing in the diffuser through its sides despite the high ride height.
The whole concept seems to be more efficient at creating overall pressure change and downforce from the floor and the diffuser.
But note that every part of the Red Bull needs to be looked at as a whole concept, not individual pieces. And it's the sum of all parts that make the RB7 a fantastic car. Rival teams such as McLaren and Ferrari cannot just simply jack the rear end of the their car and expect a sudden gain in downforce…
