Well as far as I am aware, this is part of the launch control system guys, but only applies to manuals. If you are at a standstill, put the car in first and then rev to 3500rpm, you will hear the engine change sound. This is one or two cylinders turning off. You then dump the clutch and the car will do the rest. When you change gears you will find that the clutch is soft till about half way down the pedal and then feel hard. Make sure you press the clutch alllllllllll the way in before changing gears. When you change from 2nd to 3rd it will be soft as well and then feel hard, half way the pedal. I believe this is the launch control doing it's work, but it will burn the clutch. I don't like it at ALL. I had the burnt clutch smell going through the car for the rest of the day through the ventilation system even though I wasn't going hard at it.
