Red Bull RB6 – exhaust development from Spain to Japan

   Spain

          At Spain further modifications took place not only at the exhaust outlet shape and length  but also to the area around them .  The new outlets of reduced length  were cut of  vertical at their end and were relocated a bit outer from their original placement ( bulgy car bodywork around them )  . Furthermore the exhausts blow  inside a channel which offers a better guidance of the hot emissions towards the diffuser  .

           At Canada the exhaust outlet length was reduced further being now barely visible and almost completely covered by the car bodywork .  This version is being used since the Japanese GP  ( this post was written after Suzuka race and before the Korean one )   .

Red Bull RB6 – exhaust development from launch to China

   Launch – periscope exhausts

Red Bull was the first team to re-introduce the  Exhaust Blown Diffuser system in modern Formula 1  . Initially the RB6 was launched with periscope exhausts blowing just above the rear suspension’s wishbones . Later during winter testing the exhausts were repositioned close to the floor and under the suspension wishbones in an attempt to energize the diffuser causing it to produce more downforce .

  Winter testing – fake exhausts

The team tried to keep the new floor exhausts unnoticed by placing fake exhaust heat covers at the former upper position . Moreover the additional vertical floor fence which was tested  also , made the exhaust observation  even more difficult .

At Bahrain the fake exhausts were removed  while later at China the engine cover’s rear part was revised . This black coloured new part  can be separated from the rest engine cover and the change was  triggered  by the mechanics need to reach faster and easier the new floor exhaust internal area.
