The constant advice for QP V and Coupe/GranSport drivers is to "always use Sport mode to save the clutch." I can't speak to every single car, but in my 2005 QP the chief difference between Sport and regular mode is that the gearbox shifting is much faster, so the clutch is disengaged for a shorter time during gear shifts. For takeoff, Sport mode maybe uses about 100 rpm higher to engage the clutch. I find that the regular mode shifts more at the speed of a person driving a manual, and I also like the softer suspension setting. It would be nice to use regular mode without having to worry that the clutch will self-destruct. After running 3 years on a clutch installed in 2017, I decided to do a little experiment. Clutch wear readings generally showed that I was using about 18-20% of the clutch per year (5000 miles) exclusively in Sport mode, for the first 3 years. I drive mostly in city traffic. For the 4th year (2020) I decided to drive mostly in regular mode, since I prefer the ride setting and the shifting speed, and I didn't much care if I wore my clutch out. When they checked the clutch last week, they told me it was "no spring chicken" but was operating well and would be good for one more year, based on visual inspection. This shows that the normal mode (shifted manually) does not necessarily wear the clutch at a much more rapid rate than the Sport mode, if you control the most important variables which are car, clutch, driver, and operating conditions.
