Sorry if this is on here somewhere already, but i had a quick look and couldn't come up with anything.

I'm after the 6 gear ratios as well as final drive ratio and all that jazz for the mighty '6.

Using figures from my car for an assignment i'm doing...except i don't know them! LOL

Any help or pointers as to where i can find them on the net would be great!

Cheers

ok, more help if anyone could be so kind...

i haven't really had my '6 that long, and not driven it hard enough, often enough to really know the answer to this...i'm doing caclulations regarding the revs the car will be at in the next gear, if taking each gear through to the red (i'm using 7250 for the sake of my work)

just not sure my numbers seem right, but i don't actually know what revs it really drops to when going through the gears properly

I have (rounded of course):

2nd - 4650
3rd - 5410
4th - 5920
5th - 6000
6th - 6090

just seems like the last few are a touch high?

i thought it dropped to closer to 5k in each gear...

70 MPH = 3246 RPM 80 MPH = 3709 RPM 90 MPH = 4173 RPM 100 MPH = 4637 RPM

Top Speed in 1 gear = 42.528 MPH
And changes into 2 gear at 4636 RPM dropping 2614 RPM
Top Speed in 2 gear = 66.511 MPH
And changes into 3 gear at 5485 RPM dropping 1765 RPM
Top Speed in 3 gear = 87.913 MPH
And changes into 4 gear at 5886 RPM dropping 1364 RPM
Top Speed in 4 gear = 108.282 MPH
And changes into 5 gear at 6006 RPM dropping 1244 RPM
Top Speed in 5 gear = 130.713 MPH
And changes into 6 gear at 6061 RPM dropping 1189 RPM
Top Speed in 6 gear = 156.363 MPH

That is good info rich, do you know the figures for the xsara vts 5 speed box.

Would be good to see both figures side by side.

Here's the data for the Xsara VTS 'box. It's a little shorter geared than the GTi-6 'box overall with larger RPM drops on each shift apart from first to second.

The first and second gear ratios are the same in both 'boxes but the VTS 'box has a slightly shorter final drive ratio.

Gearbox:- Xsara VTS
Tyre:- 195/55 x 15
-------------------------------------------------------------------------------------------
Top Gear gives 20.515 MPH/1000 RPM and a top speed of 148.732 MPH at 7250 RPM

Engine speeds in top gear:-
30 MPH = 1462 RPM 40 MPH = 1950 RPM 50 MPH = 2437 RPM 60 MPH = 2925 RPM
70 MPH = 3412 RPM 80 MPH = 3900 RPM 90 MPH = 4387 RPM 100 MPH = 4875 RPM

Top Speed in 1 gear = 37.908 MPH
And changes into 2 gear at 4636 RPM dropping 2614 RPM
Top Speed in 2 gear = 59.286 MPH
And changes into 3 gear at 4965 RPM dropping 2285 RPM
Top Speed in 3 gear = 86.566 MPH
And changes into 4 gear at 5387 RPM dropping 1863 RPM
Top Speed in 4 gear = 116.514 MPH
And changes into 5 gear at 5680 RPM dropping 1570 RPM
Top Speed in 5 gear = 148.732 MPH
