I have tried sport response button several times at different speeds between 30 and 70+ mph and don't get the point of it. The gearbox drops down a cog or three and the revs go up to 6000+ which is not where the torque is with this engine. The button is supposed to be for overtaking but in actual fact the car accelerates more quickly by just putting your foot down without forcing a massive down change, just letting the mid range torque do its job. Any body got a similar or alternative experience ?
