They dropped the TFSI name because of something to do with using the term 'Fuel Stratified Injection' I was led to believe?
So now its the same engine as before only a new name. It's not to be confused with the TSI on the 1.4 VAG engines which stands for Turbo Supercharged Injection ie the twin charged engines.
I wish they did twin charge the 2.0 litre lump.... hmmm
