when holding a steady speed the turbos not on boost so the engines works more like its NASP equivalent in other words theres not as air going into the engine so not as much fuel is required and more economical.
as well as the lighter engine

yeah the TFSI engine its supposed to be very nice to drive . i remember VW were talking about putting it in the passat as a possible replacement for the R36 engine as a GT car. its also turned up in the VW cup in a modified golf. it was doing well as it was much more economical than the R32 VR6 and 1.8t that were racing around with it so could carry less fuel, so less weight.
yeah the S2000 is where factory NASP engines are getting silly 240-250bhp from a 2ltr 120bhp/ltr and this from a factory tune engine
