An interesting piece on AMuS https://www.auto-motor-und-sport.de/for ... nterboden/
discussing whether the new floor rules for 2021 will disadvantage the high or low rake philosophy more
It also suggests McLarens move to a Mercedes style nose indicates they will run less rake this year
I have read somewhere that the high rake concept isnt as developement friendly as the low rake. just look at RB for all these years and still cant beat Merc.
The lower rake concept is the way to go
That statement is so misleading it isn't funny. You make it sounds like the 2 cars are identical, the only difference is the rake.
Fact is Merc have had issues getting high rake to work, their cars have increased rake over the last few years. Think they were up to 1.7- 1.8 this year where RBR are at 2.3. Don't forget Merc's car is longer than the RBR, it need less rake to get to the same height. Also you talk about rake like rake is always on. Once a car hit 150KPH, rake is gone.
If teams have lower rake this year, including McLaren, it will be cause they have problems sealing the floor with the reg changes. I presume they will not fix they're mechanical grip issue out of slow corners this year, its been there in a varying degree since atleast 2014. Lower rake will make them even slower out of corners.
You might see them come out with lower rake and slowly increase it as they figure out the new regs.
Remember you need more rear wing to make up for less rake. More rear wing create more drag at high speed.
From https://en.wikipedia.org/wiki/Drag_(phy ... (60%20kW).
Note that the power needed to push an object through a fluid increases as the cube of the velocity. A car cruising on a highway at 50 mph (80 km/h) may require only 10 horsepower
(7.5 kW) to overcome aerodynamic drag, but that same car at 100 mph (160 km/h) requires 80 horsepower
(60 kW). With a doubling of speed the drag (force) quadruples per the formula. Exerting 4 times the force over a fixed distance produces 4 times as much work. At twice the speed the work (resulting in displacement over a fixed distance) is done twice as fast. Since power is the rate of doing work, 4 times the work done in half the time requires 8 times the power.
Rake difference will likely disappear next year when the rear wings are are far smaller.
