Red Bull RB20 Tech Analysis

Red Bull RB20 Tech Analysis



February 16th, 2024

Red Bull as all other teams have recently revealed their brand new design and car for 2024 season. We are going to see the full Red Bull tech analysis and their new features. 
Red Bull apparently took a huge evolutionary step as everyone converged on what Red Bull came up with in the first year of these regulations. A design that minimizes surface area is most noticeable by the upright radiator intake that sits snug inboard and runs to the chassis bottom. 

This Red Bull tech analysis revealed the inlet is shaped like the 2022 zero sidepod Mercedes, although it's employed differently. Red Bull preserved the sidepods and employed the vertical inlet to give them a massive front undercut, unlike Mercedes. 
Its aerodynamic philosophy differs from the original zero-pod Mercedes and the last two Red Bulls.

As radiator technology improves, coolers can be smaller while still absorbing heat. This, together with Red Bull's ability to intricately mold the radiators into elegant compound curve shapes to maximize aerodynamic impact (shown in last year's RB19), allowed the radiators to be placed lower in the RB20.
The radiator region was placed lower around the centreline, lowering the centre of gravity and allowing the crew to rethink the car's configuration. 

The radiator inlet is now below a bodywork lip, matching the radiator height drop. But placing a horizontal entrance lower would have taken away space for the undercut, which accelerates airflow down the floor edges toward the diffuser. Vertical form yields a lower inlet and better undercut.
The high bodywork shoulders, which produce a depression between them and the engine cover (like the '22-23 Mercedes), suggest that cooling air flows from the radiators to the rear. Lower sidepods are aerofoil-shaped and lighter than before. 

In addition to changing the cooling layout, relocating and miniaturizing the radiators has allowed the rear upper bodywork to be very short and ramp down sharply, producing space ahead of the rear wing. While short, the sidepod adds volume to improve airflow around the diffuser.
This extensive top bodywork rebuild maximizes the underfloor's performance. With stronger airflow around the sidepods and floor edges, the venturi tunnel geometry will have been optimized, which will frighten the opposition before the season.
