Congrats on breaking the 3L/100km barrier, tasdrouille!

I can't deny I'm quite envious. My TDI's having problems breaking 50mpg steadily, mostly, I think, due to the (once again) bad Mass Air Fuel sensor.

Your pictures show well enough what you've done aerodynamically, but, can you give more specifics about the driving techniques?

What sort of engine load do you try to maintain while accelerating to cruising speed?

Do you use cruise control to maintain your steady speed, or do you rely on your foot mainly, to hold a smoother cruising speed?

Is your speedometer slow compared to Scanguage's kph output, like mine?

I'm asking these questions given that most of the TDI engined VWs tend to behave similarily.

And in my case, the only difference between our cars are the level of aero modifications, the one year different model year (2000 A4 vs. your 1999 A3), and my full sized spare is on, so I only have three winter tires right now.
