I think the mags are quoting 211PS as it fits in with VW reducing there CO2 figures for the mk6 golf over the mk5's. This would meen it uses a version of the new Audi A5 engine that only puts out 154g/km in the A5 so reduces the GTIs tax band and gives people an option of a decent power output with lower tax and co2 output or a full fat 270PS 4WD GTI-R (201g/km).
Makes good sence to me for them to do this rather than limit themselfs with the current Ed30 engine or using the older GTI engine that are ~190g/km and maybe putting some new buyers off in the future years due to the rising cost and scales of road tax price not just here but also other places.
