Tiptronic question (but ultimately about "lugging the engine")

[rp17]

Idleness I don't drive a tip but redline is around 7-8k so that wouldn't be considered lugging the engine. Lugging is driving around in to high a gear with the rpms around 1-2k. This also puts alot of stress on the Ixx. Think of it as driving around in 5th gear going around 20mph. Thats lugging!!
Some of the track guys who corner at rpms higher than that might chime in but there shouldn't be any harm done to the car. These are high revving engines after all.
