And these, rather than a flat floor and this ‘kick line’ that ramps up into the diffuser. So flat floor with air being pulled through by a large diffuser. Now, we’re going to have these sort of three-part tunnels throat so

you'll have this bit by the side of the cockpit where you have a ramp section going down converging and then you have a section which i've described in some of my drawings as a flat floor it's not strictly flat it's kind of curved then you're then allowed to have a much bigger effectively a diffuser which is just an even bigger tunnel starts much earlier if we go back to the

journey of the air going under the floor the air will arrive at the front of the car so the air will arrive pretty much untouched and then go into this converging section and it will start to accelerate as it goes into this converging section until you reach that first kick line and this is where you'll get the first burst of downforce the first burst of really low pressure the air will then continue to accelerate under that middle flatter section of floor
