I knew my boy was fuel efficient. I didn't know it was that fuel efficient.
3.6 L / 100 Km. Don't know how many mpg. Nothing put of the ordinary, just a 160 km / 100 mile trip, some highway and some backroads. I just went slightly slower than usual because of the heavy rain. And I have to say I'm impressed.
1.4 turbo diesel and 5 speed manual, for anyone who wants to know.
