Does anyone here know of any good published comparison between the 2. From what I can gather the 1.6T Smartstream engine is a whole new design which has the new CVVD tech to replace the Gamma 1.6T. It seems like a huge expense to design a new 1.6 from scratch when they already have one that AFAIK was known for being a good reliable engine. I'm curious to know what else is different about them, but I have found very little info. Does anyone have any info a links to share about this?
