can make smaller turbo engines more effiecent and faster than a larger engine these days, new focus has the 1.0 turbo that is the equivelant of the 1.6, and driving it, it is just like driving a 1.6, new st is a 2.0litre direct injection turbo but is putting out more power than the old 2.5l turbo in the last st
basically manufacturer wise its all about emmisions these days and its harder to keep the emmisions down on big n/a engines, and get good fuel effiecency as well,
