For the 1.2 TSI Skoda says 175 Nm and 107 hp. The Poles got 13% more torque and 17% more horsepower. A Spanish magazine got similar results: http://motor.terra.es/pruebas-coches/articulo/skoda-yeti-suv-55682-datos.htm

In Finland the tax is based on CO2 emissions and they are checked by the authorities. It would make no sense advertising lower ratings, because the truth would come up anyway. Maybe the power output is not checked by authorities in those countries where the tax is based on power. But then it would make sense for all manufacturers to show lower power ratings, why would only VAG do so. Anyway the Polish figures seem nice: 199 Nm and 125 hp are more than I had in my 2.0i Vectra.

Surfing around the net I have several times read someone mentioning that VAG has a habit of understating the power of their TSI engines and maybe other engines , too. Does anyone have any solid information on this? Any measurements for the 1.2 TSI for instance? Why would they publish lower than real power ratings? Wouldn't it be wiser to announce true horsepowers and torque or even exaggerate a little? The CO2 emissions are accurately monitored by authorities, but aren't they interested in measuring power, too?
