Decided to give Sport+ mode a go today. Flicked over to it at the lights on the way home from grocery shopping. The idle went up from about 650 to 800, and when I gave it a bit of happy juice to "get up to the legal speed limit" the punch around 3,500 was noticeably more potent than in Normal mode. Change to second wasn't (longevity of) tyre friendly. The 80 kph speed limit came by rather quickly. All in all I think I'll stick with the Normal mode mostly - but it is nice to know what the others do. That said I am not quite ready to give the Track mode a test just yet haha.
