Hm. I still don't get the point.
For the 1 series there even is no 130i. There is a 128ti and a 135ix. I maybe would get the point, if there would be a 128ti AND a 130i ... and tests/comparisons of both had shown, that philosophy/setup of an 128ti is different than for the 130i. Maybe (this you seem to imply) more sporty, more wild...
And then you also seem to imply, that - in case such a difference between a 128ti and a hypothetical 130i would exist - it could be transferred 1:1 to a totally different vehicle (RWD CLAR platform vs FWD FAAR platform).
I fear you have fallen for BMWs advertising with the ti letters

All the test, which I've read (not pre-series but the final product) against its competition (Golf GTI, Focus ST, ...) were not in favor for the BMW. Overly harsh ride, understeer as hell ... but nice decals applied...
But you all seem to be even bigger BMW fans than me, that you have such high hopes in a ti-model
