Try this: drive the car at low rpm steadily until the engine warms up (when that temperature icon goes away). When the engine's properly warmed up, floor away
I believe the car can also "learn" the way the person drives, so if I'm driving slow most of the time (for fuel economy), the car will appear to be less "enthusiastic" especially the way the engine outputs the power. Some people elect to disconnect the battery to "clear out" that learning memory from the car's computer. I on the other hand just keep it in a lower gear and floor the pedal until it reaches redline, that will sort of wake up the car's computer, letting it know I wanna have some fun
