Final drive ratio ???

[damon6uk]

I'm so confused I don't have a clue about this
It say "a final drive ratio is a gear ratio multiplied by the drive ratio "
Could anyone help
The cars a 1.2

I think most of us regard the axle ratio as the 'final drive ratio', so it sounds as if whoever you were "quoting" was giving the overall engine to road wheel ratio by multiplying this by the gearbox ratio.

Soo confuseddd
Do you know what it is for a seat Ibiza 1.2

 

[Edward9th]

The only figures I have are for the 1.2 'Reference':-
Final drive ('axle/group ratio') 4.188
5th gear (I expect this is the one you want) 0.851
These are from a 2006 brochure.

Are all it gear ratios in the book

The final drive ratio is usually the differential. You multiply the final drive ratio with whatever gear ratio you're looking at, that gets you from engine revs to wheel revs.
