FSi TFSi and TSi

[ford776]

What the difference between a FSi, TFSi and TSI. I know the difference between the FSi and the TFSi is the turbo, but what a TSi?

True when they were first released but not anymore I'm afraid. The Octavia VRS/Golf GTI etc uses a 2.0 TSI petrol engine and that is only turbo'd - it has no supercharger.

Surely Turbo Stratified Injection would be more appropriate?

As lots of VAG group cars are badged TSI, but not all of them are supercharged.
