I've only recently taken ownership of my Boxster and reading the post on "
Tiptronic in Manual Mode", I have just discovered a whole new car when driving in lower gears in manual between 5,000 and 6,500 revs (I think my 2.7 red-lines at 7,000?). Enormous fun, but still couldn't quite bring myself to take it right up to the Red-Line yet. Guess I'm still worried the engine will come out of the car over my left shoulder (UK).
Gentle driving in Auto is giving me around 26MPG, driving like last night probably around 21MPG.....but hell, its only fuel!!
