CLA 45 (US) vs CLA 45s (EU) Hardware Differences (C118) Question
Hey guys, I'm new here. So obviously before you crucify me, yes I know the 45 (US) and 45s (EU) have different HP and TQ and there are various emmision differences in the exhaust. However, my question is what exactly is giving the 45s an extra 40+ hp and 20 tq. Is it as simple as a tune Mercedes made for the 45s or did they also beef up the internals. From what I understand, it should only be software. Enlighten me please. And would raising the Hp and Tq to the Europen variant decrease reliability dramatically? In a sense, sure it will decrease reliability but hasn't the car proven it can indeed handle the increased hp and tq. Should I tune via a reliable tuner to the EU spec is what I'm trying to say lol.

Yes, I've also confirmed this with a tuning company in Germany called Opus, which I believe used to be Renntech. Now I guess the only thing is.... is that system solely software or is there hardware involved. I would assume in this case both.
