After having used a very shallow and low rear wing in the Spa to compensate for engine power deficit compared to their major rivals, Red Bull went a step further on Monza and brought an even more extreme rear wing that produces even less aerodynamic downforce and drag.
For years, Red Bull have been using lower angles and smaller rear wing surfaces to compensate for the lack of power of the Renault power unit in comparison to Mercedes and Ferrari, and thanks to a large downforce from the floor smaller wings can be used.
The downforce from the floor is aerodynamically more efficient than the one gained from the wings, which means that for the same amount of downforce it generates less drag and Red Bull for Monza went quite extreme with the configuration of the rear wing for their RB14.
Let’s first look at Red Bull’s rear wing for Belgian GP, which is already very shallow, with a nearly flat bottom element (purple) and a low inclined upper element (turquoise).
Also, the side plates (orange) have no horizontal slots because such a low wing does not create so much turbulence at the wing tips to use those kind of slots.
In the following photographs, there is a rear wing for 2018 Italian GP which is even more extreme and whose upper element (flap) is even less inclined (purple) while the main plane is almost flat (pink) and has a leading edge curved inward.
