Red Bulls Monza Front wing

Red Bull have appeared at Monza wit the expected specialist low drag wings. However their front wing sports a new detail inspired by McLaren. The “r” shaped inner cascade, has been a feature of McLaren since late last year. This feature has also been used by Sauber.
The horizontal section will probably directly produce some downforce while the vertical sections is more likely to act like a turning vane to direct the general airflow outwards.
For this race Red Bull use a simpler three element wing, with the trailing edge of the flap cut back to create a shorter chord for less downforce.
