McLaren uses the plate behind the chicken wing to guide airflow around the bargeboard, but there is a void and little flow conditioning, not to mention the plate is interfering with the airflow coming off the chicken wing. This flow stagnation along with a lack of devices in this area is the reason for their lack of overall downforce. The faster teams use vortex generators and the chicken wing elements instead of the plate that McLaren and Renault use. The further outboard the plate behind the chicken wing is the worse it is from an aero stand point. It creates heavy flow stagnation, and robs the diffuser of precious air-mass.M840TR wrote: ↑30 Jun 2018, 22:15Is that not the mid-wing? And you mean to say that since that is guiding air under the floor Mclaren feel there's no need of the vortex generators on the floor leading edge?diffuser wrote: ↑30 Jun 2018, 22:01godlameroso started referring to it as that.

Look at the Williams, they still just have a vertical plate, the only team to be so behind in this area, and they are the slowest team on the grid.
This area is extremely critical for aero performance, just look at how bad Haas was in Monaco precisely because they had to revert to a more simple setup for the race. Due to it breaking off when hitting curbs etc.
