Formula BMW: Street Circuit + Open Wheeler = ?

Footage from 2009 Asia Festival of Speed at Macau.

Enjoy! :wow:excited

It’s so blind that the drivers didn’t know about it at all until they’re on top of them. Even on a caution, you wouldn’t expect to come around the corner to see that mess 50ft ahead of you, and with nowhere to go I’d bet most needed a change of shorts in the pits.

Looks like only a handful made it through unscathed at all but I’m :rofl hard at the guy continuing to drive who’s oblivious that this left rear wheel is completely twisted around!

Macau is greatness. Half the drivers that stuffed it after the initial wrecked did so because they locked it under braking and spun.

yeah, they came around that corner and just panicked. Handfull of them kept a grip on the issue and managed to skate through all the others bouncing around the track.

So it was the heavy braking that caused the over steer not just the sudden lift off on the throttle?

I love how the yellow car went on after barely avoiding the accident as it happened right next to him, spinning and hitting the wall.

Losing the rear under heavy braking at speed while you car is turning is simply a more severe form of trail brake oversteer, which is a more severe form of trail throttle oversteer; Racing, in part, is nothing more than a game of managing weight transfer to maximize available traction.

Macau is a very challenging circuit not just for drivers, but is a nightmare for engineers to have the car set up. Not only is it extremely bumpy, so the engineers will have to make a compromise between bottoming out the car and suspension compliance. The corner where that accident is at is call the “Maridian”, which is the fastest corner of the circuit, cars (especially open wheeler) are usually set up to have just enough down force to take that corner flat out. If you don’t you will get pass everyone behind you once you reach the real first corner of the circuit “Lisboa”, where you will see people going 3 or even 4 wide jockeying to take the corner first. Once you are on the mountain section, passing is basically impossible until after you exit the hairpin at “Fisherman” and “Reservoir”.

Both/either/or. It’s all just weight transfer forward off the rear wheels equating to less traction in the back.

Edit: Nm, totally missed the post right above this.
