Anybody know what the gear ratios are for the 5 speed 998cc ecoboost mk7.5 Fiesta.

Haines manual says it is the IB5 box which is the same as the Mk6 and I think the Mk5

I have found a number of places suggesting it is 3.15, 1.91 1.28,0.95 with final drive of 3.82. Anybody know for certain ?

Thank you for the replies.

We are having a go at climbing in a road going class and wanted to figure out the optimum gear change points. For what we are doing the gears are far too long. Plainly the car is not competitive in the class as it is far too heavy. 1960 minis, midgets and the like are far quicker but it is a bit of weekend entertainment.

Realise we will probably break the gearbox at some point.

The car is 2014 125 bhp so will calculate with the ratios you have suggested.
