yah good plan by audi/VW using the 4-cylinder turbo
that also applies on the 335i though, because it has an hp output of a V8 (306hp, that's almost the same as the 540i)
but yah the 335i price is kinda high, although my cuzn thought it would be more expensive looking at the prices of other German brands (Merc, audi) and some thought it would be more expensive cuz ur buying a BMW
