That has nothing to do with the engine supplier. The team made it themselves. The earliest thing Red Bull did was to blow with hot air.

This thing is a kind of blowing diffuser. The so-called blown diffuser is to use the airflow discharged from the exhaust pipe to blow through the diffuser, which can speed up the airflow passing through the diffuser and provide higher downforce.

Hot blowing and cold blowing are two technologies of blowing expander at present. Cold blowing uses normal ignition time to discharge gas, while hot blowing adds partial ignition on this basis, which can make the airflow more violent and the blowing effect better.

The FIA has banned hot blowing, and cold blowing is still allowed to be retained. However, according to the FIA's plan, in the 20 12 season, all teams will be required to move the exhaust pipe to the rear of the vehicle, so as to completely eliminate the influence of exhaust gas.

However, the impact on RBR should be limited, because RBR has many advantages. Banning blowing hot air does not mean that RB7 will be pulled back to Earth.
