My 2026 Elegance in the first tank gave me like 4.73L/100KM. (33.54L and 709.4KM). I think car total trip was like 4.5L/100KM. But this could also vary depending on how far they filled the fuel the gas station employees.
This is for extra-urbane usage, and mainly I do every day 2 trips to kindergarten where i hit like 60 speed bumps (15 per way) one way is more uphill, the return way is mixed plain/downhill.
As a reference my 2014 Diesel Outlander consumes like 7.6L/100KM with this usage.
Overall I'm really happy with the Jazz fuel consumption.
