Dr Obbs alluding to the front wings again. It's quite obvious this is where Mclaren and Mercedes have found a lot of performance. Everything adds up.
The RB20 needs that front wing update soon to be able to balance performance like the others.
All of the competitors used to say last year that Red Bull was the best on tracks that had different corner types because the Red Bull could work with multiple corner types while their own cars could only be tuned for 1 type of corner. Stella stressed that earlier this year (Mclaren overperformed in highspeed, and was awful in low speed), and then they did the upgrade admitting that they found a bunch of low speed performance which was their weakness but they wouldn't say why out of fear of pointing rival teams in the right direction. He kept talking about compromise.
James Allison said the same thing at Merc. They were always struggling with consistent balance when there was more than 1 type of corner (fast, slow) on a track. Then they had their eureka moment, and introduced a front wing that
had a flap and it was flexing (but passing test). go figure...
These flexible front wings are allowing them to have optimal aero balance across all corner types because they have big fat loaded front wings in the low speed, that back off their angle reducing both load and drag in the high speed corners. You want the pointy front and lots of load in the low speed, but to back off a bit to get more stability in high speed and less drag in the straights. It is like adding 1+1 to realize how a very flexible front wing allows them to achieve this. In the old regs, teams had suspension systems that just flat out
lowered the nose of the car when the wheels turned in low speed corners to increase the front wing load (ground effect increases). These suspension geometries were banned. Now they are imitating this with flex. They run high load wings at slow speed that back off at higher speeds to reduce drag and optimally steer the balance at high speed.
