Well i've had a dig around a few places and come up with the following.
I've got tyre diameter as 61.236 but
here works it out to 61.1cms... This is assuming you're on 205/50/16s?
Gear ratios from
here 1st 3.8
2nd 2.24
3rd 1.52
4th 1.16
5th 0.91
Final 3.11:1
Drag coefficient: Ranging from 0.31 to 0.33 on different sites... Have a look at
this link. They seem to have provided numbers in bold and calculated numbers in standard text. It looks like
CD: 0.31 claimed
CD: 0.32 calculated
Frontal area: 1.950 claimed
Frontal area: 1.969 calculated
Shame it isn't English though... If you know a thing or two about this drag thing, I'm sure it would make a lot of sense. I believe we have a couple of fccukers with a background in this 'area'
?
