Steering ratio E85 / E89

[zEdP]

Does anyone know the steering ratios of the E85 (non-M) and E89?

I have the feeling that the E89 has a smaller gear ratio than the E85.

Not sure about E85, but E89 is 15.9:1.

Hi fxhomie,

I don't know if there is a specification difference of US/EURO models on this, but I have found a document of BMW, stating that all E89 models have a ratio of 14.36. http://www.lifepr.de/attachment/1152...ifications.pdf

I have found also some other ratios:
E85 1:13.7*
M E85 1:15.4*
E89 1:14.36

*values from non BMW sources.

Hmm, my figure was taken from a Road & Track test. Perhaps NA has a different ratio, or R&T gave out an incorrect figure. 14.26:1 is a quicker ratio, and more reflective of sporting intentions.
