Holy crap, it's like the pikes peak version of slot cars!

Indeed! Notice that the front wheels are exceptionally tiny and narrow, since all the front cornering forces are carried by the slot guide pin.

It's time to remember the Williams FW13.

Isn't that the FW33? The 13 was a rather different beast! 8)
If you are more fortunate than others, build a larger table not a taller fence.

Actually we're both wrong. I think its the 35. And I'm now noticing it looks like the shark fin was photoshopped off. Which really emphasizes the shape of the rear bodywork.

Yes, 35 looks right.

Yeah roon, that swoopy Lambo Miura shape.. sure looked 'aero', but actually suffered excess lift at high speed..
As did.. the Lola-Ford.. of similar vintage.. so ugly add-ons.. fins/strakes/spoilers/dams & etc.. were also tried..

Is that strange active wing being used to help prevent oversteer? What downforce it produces is being pointed to the inside of the corner helping to prevent the tail coming around. Most odd. Funny to watch the wing wobbling as the steering wheel is wobbled by the driver's hands - presumably caused by track bumps.

Looks like a solution looking for a problem...

It makes perfect sense, though I think it looks too weird. And possibly also too slow in response.
But it makes perfect sense to angle the downforce toward the inside wheel, so the force is more evenly distributed. It's an aerodynamic version of a roll bar.

“When the wing is tilted, downforce is only decreased by 3%, while an inward directed force of 30% of the wing downforce is generated.”
