Coming home from work last night, I filled up the replacement S40 as I expect to get my own car back later this week.
I beat 4L/100km by a hair:
3.9993 L/100km = 25.0045 km/L = 58.81 mpg(US) ;-)
Now why doesn't my wagon get that kind of mileage
It can't be just the 0.01 difference in Cd, can it ?
S40 : 0,31
V50 : 0,32
A = 2.20 m2 (both)
I've added the Cd values to the Wikipedia Cd-page.
