Hi,

here is the answer:

the aritabs were not used at the rear edge of the car, but in front of the wheelhouse.

So this values are not to evaluate Airtabs as the intended use case.

CW Widerstand drag
CA Auftrieb gesamt lift
Cav Auftrieb vorne lift front
Cah Auftrieb hinten lift rear


Serial state, Serienzustand
speed 140 km/h
CW 0,323
CA 0,0402
CAv -0,0223
CAh 0,0626


Xanon aerodynamic bumper with vortex generators
speed 140 km/h
CW 0,2971
CA 0,0256
CAv -0,1053
CAh 0,1309



Xanon aerodynamic bumper without vortex generators
speed 140 km/h
CW 0,2961
CA 0,0213
CAv -0,097
CAh 0,1184
