Essentially what everyone else said.... the compression ratio in this car is insane (in regards to the norm), and despite it's "lack" of power it still makes 100hp/L which is a VERY performance orientated engine. If you want to play you gotta pay
Come to think of it... almost all of the looney hot hatches now a days make well over 100hp/L, the 15' Golf R for example makes 296hp from a 2.0 for example, that almost 150hp per liter.... which is utterly ludicras
