The fact that these fellas are running a two-car team is what's blowing my mind lol it really shouldn't but it does. 2:45 Not quite flying in formation but close enough for me!
yea that was what i was thinking too lol there is no flat underbody on them 2 cars so im guessing they are using a cut rear bumper for now rear bumpers without proper underbody panels will just catch air and create drag but still could use a full big ass straight diffuser just on rear it does look cool though can completely see the rear subframe and tires
Glad we were all thinking it. Could it be that the underbody tray and diffuser would be overkill for what they’re going for if you pause at 1:34 up you can see that they’re abusing ground effect to the absolute limit. There’s a channel that looks like it runs the whole length of the car to guide all the would be trapped air straight to the back and out, and it’s like @descentmvm was saying, adding the bumper would probably catch air. Doing more harm than good. If every second counts then making the car as light as possible would be the best option. So if the aero package is doing more than enough additional weight and drag would cost them time rather than save it. So cut bumper or no bumper to get out all that trapped air as fast as possible seems like the way to go. I don’t know much about aero so don’t take my word for it, just my opinion really.
Do the rules not permit any rear underbody air management? I see it has the fairly advanced infinity endplates on the splitter and extraction from the front wheels, but I was always under the impression that cutting a rear bumper like that to extract air from underneath was not a great idea. I hope I get schooled here in the comments though on how this setup is actually better. I suppose this is why one needs many years of education to fully get their head around how aerodynamics.
I think it helps reduce ballooning/drag from the air hitting the inside of the bumper. But yeah a totally flat floor with a diffuser setup would work much better for sure
It’s 2 fold, 1 to get the pads closer to the rotor before braking when your pads are low and 2 more importantly/ more commonly check for brake failure prior to heavy braking from a long straight. Just a tap to make sure the pedal doesn’t goto the floor
