Tell me which car it most matches in shape

[adriansnetlis 0]

Hi! This is a custom car model. This car doesn't exsist in real life.

 

Here I couldn't add sketchfab model preview, appearently theese forums doesn't support BB code. So I just place a link:

However, to make it feel natural when driving, I need this car's equalient coefficient of drag aswell as frontal area. To find out the most suiting Cd, I need to know which car does this remind the most in it's shape? Exact model, exact manufacturer. The more accurate the shape matches, the better. I don't know much cars, how they look and so on, but I hope that somebody can recognize a car when looking at this. I mean a real existing car.

Thanks for help!

Well, the body is unrealistically tall and not very long, and the roof line is unrealistically short, so it really doesn't resemble any real cars. The closest would be the last generation Supra. And remember, for drag, you have to factor in how much drag tat rear wing adds.

Thank you Chris. Yeah, the wing(aswell as body kits and so on) will be calculated in weight, drag and other stuff like that. Thanks for answe, I will assume that it is something similar to supra. I may also edit the shape a bit...

Reminds me of this, a 350/370Z

Well, if you say so, it really does when I look into deapely. The rear especially. Only exception - the car I own is not such rounded. I may choose a midway between supra and 350z. Maybe use 350z aerodynamics and supra engine? Because the supra engine and 4-gear automatic transmission acts well in my game. On startup the acceleration is low, but when RPM raises, it is huge. Plus I can acheive 300 km/h and it takes pretty short moment:)

 

However, I need info about rear wing that the car has for now.

 

1st: How much does it affect air drag coefficient. Does it increase the number(make drag affect car more) or decrease it and how much(approx) does it change it?

2nd: How much the wing may weight(in kgs)?

3rd: How much does the wing prevent car from rolling? Assuming that roll factor is a number where the less it is, the less car rolls and at 0.05 roll factor it behaves like this:

 

Thanks for advice in those questions:)

I feel like the one above is advertisment. It doesn't sound good at all...

yes, it was. I got rid of it.

 

As to your questions, the wing adds drag but it increases downforce for more cornering stability. How much drag is determined by shape and angle of attack.

 

As far as weight, it's not going to be much, not more than 20 lbs (about 9 kg)

 

It affects roll by providing downforce to keep the rear of the car planted. Since it doesn't add noticeable mass, just force, there is no more mass to make the car roll, and there is more stability to keep it from rolling much, though the amount it keeps it from rolling is still fairly minimal, as the suspension (springs and anti-roll bar) do more to change that.

OK! But, assuming I've got a 0.05 rolling value, how much would it remove? And, if my car has 0.64 CaD(Coefficient of area * drag), how much would it add to it?

Err.... I can't hate those advertisers. Why have they found my thread for their advertisments? How they dare it???
