A quiz for people
 

So here's a good example of a really low drag vehicle - incredibly well streamlined with a Cd of 0.101 - yes, 0.101.

It's the 1996 Honda Dream solar race car.

Now, who wants to guess whether, overall and at zero yaw, it has:

(1) Downforce
(2) Neither lift nor downforce
(3) A small amount of lift
(4) A lot of lift

Just putting down the number that corresponds with your guess would be good.

5

;)

3, though the question is subjective.

Wondering why the wheel cowlings weren't combined?

3.5

Pi

I'll take that as #3!

4

I won't guess since I just downloaded and read the paper, but I will say: not what I expected.

It looks like a wing, so I would say 3.
If the part under the car (between those wheels) is flat, straight and not curved, I would say 4.

Not an informed guess but if I was piloting that through the Oz-tralian Outback, I'd want downforce, just in case. :eek:

Zero yaw is a momentary condition.

FYI: EcoModder has a polling function.
