Depends on your definition of city driving.

For 2.0:
If it's the typical metropolitan crawl during peak hours where you spend more time stuck in jams than actual moving, expect your FC to go up as high as 11-12L/100km.

If city driving means you are able to maintain a pretty constant leisurely cruise around 50-60kmh, 9-10L/100km is achievable.

For highway cruising at 100-110kmh, 6.5-7L/100km will not be surprising. However if you speed beyond 120km/h and maintain it at that speed, it'll easily go up to 8+L/100km even if it's on the highway.
