Here you have the fuel consumption (fuel economy) of Opel (Vauxhall) Astra 1.5D FWD 6MT with 1.5 l R3 turbo diesel engine (90 kW, 122 HP, 300 Nm) in a city, highway and autobahn, motorway, freeway, highway.

Results for Opel (Vauxhall) Astra 1.5l diesel:
eco city: 5.0 l/100 km (47.0 / 56.5 mpg US/UK)
90 km/h (56 mph): 3.3 l/100 km (71.3 / 85.6 mpg US/UK)

As always, I checked real fuel consumption on a petrol station. I noticed 2% difference: computer shows lower by ~2% 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.
