Modification Details on Red Bull RB16B

While Red Bull Racing's car for the 2021 Formula 1 World Championship may look similar to last season's chassis, in fact the RB16B has a lot of changes.

Modification Details on Red Bull RB16B

The Red Bull Racing team introduced the RB16B on Tuesday (23/2/2021). Red Bull Racing Principal Christian Horner's statement that 60 percent of the chassis components are taken from the RB16 makes this car at first glance not much different from last season.

Although the changes are only in some areas, these modifications are very significant. So, what are the changes to the RB16B compared to the 2020 F1 car, the RB16? Here's the analysis.

Nose (Nose)

This is one that was allegedly a problem in the RB16 last season. The Red Bull technicians in Milton Keynes, England, have also made modifications to the nose of the RB16B.

The main difference is that the fins on both sides of the nose are believed to change the direction of the airflow along with changes in other areas.

Last year, Red Bull had designed a small car nose that was able to change the airflow in the front area of the chassis. However, this change was not maximized when tested in a wind tunnel.

Red Bull then installed a tight pillar on the front wing in the first race of last season, but immediately removed it again. The modification reappeared at the end of the season when Red Bull fielded a new front wing change at the Turkish GP.

When the RB16B was introduced, Red Bull seemed to forget about the narrow pillar modification. However, everything can only be confirmed when the official test will be on March 12-14 or the first race in Bahrain on March 26-28.

Brake Ducts and Front Suspension Cooling System

The RB16B brake ducts are also optimized. The lower inlet cross-section is narrowed to increase the airflow around it. Similarly, the aperture of the component has been changed quite significantly compared to other cars (red arrow in the above inset image).

Still in that area, Red Bull also changed the shape of the front suspension struts (blue arrows) by attaching them to a vertically mounted extension bar.

Airflow Changing Upright Fin (Bargeboard)

The barge board also received attention with changes to the top grooves of the main components. In the RB16B, this component is cut at a larger angle.

Wings (Winglet) and Mini Fins (Fin)

The boomerang-shaped center wing is also different from the previous version. With the addition of one element that is divided in two in the middle.

Side Radiator Holder (Sidepod) and Engine Cover

The side-pod and engine cover have also been redesigned to be more dynamic. This change is also due to the use of a new power unit from Honda.

The new bodywork on the RB16B incorporates an internal side-pod structure allowing Red Bull's designers to take advantage of contours to achieve an aerodynamic effect on the car.

The airflow from this RB16B side-pod will lead to the rear floor of the car. Meanwhile, last season's car, the RB16, had a flatter airflow.

The base of the top cooler (chimney) is also deliberately bent downwards. The goal is to divert airflow from the holes on the left and right sides of the Halo towards the back of the side-pod (blue arrow in top image, airflow direction).

Halo has played a role in helping the cooling system and aerodynamics of
the car last season. However, this season is more refined.

Red
Bull is no longer installing mini wings under the chimney holes in the
RB16 for this season's car, the RB16B. Reportedly, they can add or not
use a number of components depending on which aerodynamic configuration
will be used.

Back

Red Bull retained the design they made towards the end of last season for the RB16B. Red Bull is believed to only use tokens to change the front.

Exhaust and Floor

Red Bull revised the shape of the exhaust since the end of last season. Precisely when they adopted a single pillar in the center of the rear wing, which is still used for the RB16B.

The RB16B floor also uses what Red Bull has tested at the 2020 Portuguese GP. Cuts on the front and rear tires with new designs are a common thing for teams to do on their new cars.
