Here you have the fuel consumption (fuel economy) of Audi Q5 40 TDI quattro S tronic with 2.0 TDI turbo diesel engine (150 kW, 204 HP, 400 Nm) in a city (urban area), highway and autobahn, motorway, freeway.
Results for Audi Q5 2020/2021 40 TDI quattro S tronic:

As always, I checked real fuel consumption on a petrol station. I noticed no difference: computer shows exactly the same fuel consumption comparing to what I refueled.
Procedure:
I drive 33 km in both ways on a highway/motorway (16.5 in each direction). Energy consumption/economy in a city is measured in real-life traffic in Warsaw (Poland) in similar conditions: the same amount of heavy traffic, light traffic and quite similar average speed.
