Before 1000km, I did notice my idle around just past 1k rpm (1100-1200rpm) but well below 1500rpm. My FC was around 7.5 km/L back then. Right now, it idles around 1k rpm but not lower. They say most 3-cylinder engines do idle at higher rpm compared to 4-bangers (usually around 700-800rpm). The weekday traffic just punishes the fuel efficiency of the Fiesta Ecoboost (doing 8 km/L now) but on light traffic, it is very good. The Fiesta Ecoboost really loves the highways and expressways. You can make the most out of its fuel efficiency and also its ability to scoot fast.
