Quote from Bob Smith :

Riel - I'm totally unconvinced that it's easier to drive on the ceiling than it is the wall. The ceiling requires lots of downforce and speed, while the wall only requires that it is a corner (and that you are travelling sufficiently fast), and I reckon you could drive around without any downforce.

Motorbikes drive around banked corners in the wall of death, and they have next to no downforce. It's all about the centrifugal force

You mean centripetal force? There's no such thing as centrifugal force

You're telling me. I've been working on the wall of death bike used in one of the missions in one of the games I'm working on, so I know it's possible without downforce. Of course a wall of death isn't your typical corner, and the tight radius means they don't need to ride particularly fast for there enough 'vertical' load on the tyres to generate the lateral grip required to stop the bike sliding down to the ground.

I'm glad i opened this thread. We should have one where all the cars equipped with active wings are listed

Another one is supermodifieds which are oval racers over here.



The big wing on top is actually controlled by the throttle if I understand how they work correctly, so on the straights with full throttle it flattens out for more straight line speed. If you look them up on YouTube you should be able to see them moving when the drivers gets on/off the throttle.

There's a clip somewhere (I'm sure it was YouTube) of someone crashing a BF1 on the back straight at Blackwood, causing it to flip upside-down where, due to the speed, it did 'fly' upwards for a few seconds.

I have seen a video similar to the one u posted but in urs the effect can be seen even better. Its exciting to see what LFS provides. I did a bit research on virtual aerodynamics and what i know so far is that working on it is something u can find a good occupation.

I was sure it had already been mentioned in this thread but looks like it hasn't. Jim Chaparral made some cars with in car adjustable aero devices. The most visibly stunning of these had massive rear wings which would adjust in pitch from almost flat to a large angle of attack depending on what the car was doing (e.g. accelerating on a straight the wing would be flat but in braking or cornering the wing would fall back down and provide additional downforce). I don't know if the wing was controlled by the driver or if the car controlled this action depending on input (steering angle or brake pressure, for example).
