The cool thing to note about this one though, is that the wing struts are mounted directly to the suspension uprights.

OMG it *is* real. Chris Rado's Scion TC.

Note: Chris is known best for his 7 second Scion TC Drag car. This is his "time attack" car.

And banned after a number of strut failures caused some spectacular crashes. The didn't have the articulation scienced out

I have see some CRAZY looking Time attack cars but this is a new one!!

Yep. Still an interesting concept that with a little more R&D could prove better than current wing mounting.

Oh, it's already way better than today's tech, since the tub still moves on it's suspension, springs can spring amd damper dampen

SO true. There were also some wings themselves that folded because they had no idea what kind of downforce they actually were creating and the materials and designs to cope with that. A few wings in the early Can-Am did that too.

Time wise at Willow Springs, that car smashed lots of proud rear and awd cars. Amazing what they're doing with this thing, even if it is a Scion. I hear/read that they're working on a new awd tC. This car makes like 600-700hp with a Scion block. Crazy. Big turbo I'm sure.

I've always wondered why no one recently had done this. Apart from it looks kind of weird, but in racing form follows function; and that functions! Especially with that kind of power, it would be the only way to keep it down.

Kudos to those guys!

I'd asked the same question and always came up this same answer . . . they just skip the problem entirely and go to the proper racing layout that transfers weight to the driving wheels when accelerating. :)

I am very glad to see this done though. I wonder if it'll catch on with other fwd racers.

It makes sense... Look at LMP cars... HUGE splitters, canards and downforce. This should work on other (RWD) cars to.. Just change the downforce levels... Downforce is like free grip.. One of the most important things in roadcourse racing is cornering speeds...
