Hypermiler.

It's tricky, but fun! Without the car coaching me (i.e. my normal driving style) I was registering about 80/100 but it seems it's all about the change-up. I was always taught around 2000rpm but this motor (a Mégane) urges 1st to 2nd at barely more than tickover.
I had ben at 95 but stopped for a coffee which buggered it slightly.
