The Koenigsegg. Because the Jesko is maybe exciting engineering, but come on... Of all the cool ways a active aerodnamic could work, they have choosen to do THIS.
Maybe this wing is generating 50kg of downforce at 200km/h. Looks like a maximum of 10% to 15% degree tilt. If we say this wing is 0,5 meters above the anchor point of the wing we are talking of 2,5 NM of torque pushing you into the corner / adding stability at the longintudial axis. At 100km/h this is theoretical 0,5NM. Or the same amount of force like a bottle of light beer in your hands.
Long story short. This is marketing bull 🤬
(If you can proof me wrong, I would be happy to be corrected. I left school in the age of 15 and have no idea of physics)
