wonder if the rapids 1.2tsi will be much different on mpg compaired to montes 105tdi

 

It'll depend entirely on how you drive it and the mileage you're doing I'd say. I get excellent economy from my 1.2 tsi.

1.2tsi seems to return 47 to 52mpg which is good

I'd imagine the tdi being slightly more but both have a 105 ps engine.Power wise would be the same. I found them to be anyway.
