So i have been reading a little bit about drag coefficient and i am still trying to understand the whole formula and how it works, but from what i have read so far the closer to "0" the better...correct me if I’m wrong though.

I was reading on motortrend and a couple other websites that the drag coefficient for the g35 is .28 - with the aero package. A lot of people have complained about how bad the drag coefficient is on the g35 From what i have researched if the drag coefficient is better the closer to 0 you get - then why are people saying that the g35's drag coefficient of .28 is horrible? The drag coefficient for the veyron, viper, and corvette are all between .32 - .44, which means they have more drag than a g35...

So compared to most cars our drag coefficient seems to be pretty damn good. Even the 350z is at .29...

Someone quoted that Any input on this subject would be great!

you're right, the closer to zero the better and the g coupe actually has one of the best drag coefficients of any production car, the best that i know of is actually the new lexus ls with .26

 

So how come all the reviews and old post are saying the G has such a rediculous drag coefficient?

it is what it is what it is...

 

Thanks for the input

I'm not sure about what the negative opinions regarding drag spawn from. But I can say this...wind noise around the driver's side window/door when hitting speeds of 120+ is LOUD. It actually sounds like my window is open, that's how loud it gets.
Maybe (and I'm speculating) the negative opinions about drag in the G spawn from the wind noise generated by the car at high speeds.

 

Bump for people who are bored at work...

It's my understanding that drag and noise are not necessarily related. But then again, I'm an electrical engineer, not an aerospace guy.

 

Less drag = less wind turbulence = less noise. The mirrors and door gaps probably cause enough to make it loud at high speeds in the G, but the smooth body makes up for it.

In order to actually get enough downforce to keep the car from lifting at 200+ mph (i.e. Veyron, etc.), you need to increase the drag on critical parts of the car --> spoilers. The trick is to find a good balance to allow the car to cut smoothly through the air, whilst preveting the car from going airborne like an F1 offshore racing boat...

 

I've been on this site for a while, and I've never heard about people complaining about the drag coefficient.

In my experience it seemed to be mainly used as marketing. When I was buying the car the sales guy told me how my aero parts would give me better a better drag co (whoa .01 better!!! awesome!)
