Weak, a 2.0L Turbo motor with direct injection should be making more than 200 HP.

No throttle plate? Yet the pictures show one.

Now I'm rally confused.

a circa-1995 4.6L Mustang GT should've made more than 215 HP too, but.... ;-)

Just like the other posters mentioned, it's direct fuel injection coupled with two intake paths, one of which is controlled by an additional throttle plate. When it's in fuel economy mode, the additional plate it closed and the charge is swirled inside the cylinder normally. When the car is WOT, the additional plate opens up, allowing more air in as well as directing the intake charge into the cylinder differently. This allows the engine to have efficient combusion for each rather than optimized for either (or a straight trade-off).
