Don't know if it's supposed to be like that. This happens on low powered engines:
The numbers of a concepted fuel saving engine and the actual numbers of it in the car have always been somewhat lower yet never that large:
Picture 1
Concept : 10km/l (25mpg)
In Car: 2km/l (5mpg)
It's always around 5-6 times lower.
Engine and gearbox had been all "fuel optimized".
