A lot depends on your driving style and the sort of journeys.

I f you are doing lots of short journeys from cold starts were the engine never gets properly hot then your fuel consumption will be pretty poor. Also the car is quite large and heavy.

Manufacturers consumption figures are total make believe and only to be ignored as they are done in a test lab and bear no resemblance to realit.

I currently have a Citroen C4 Picasso with the same engine but the EAT6 gearbox and my consumption for urban and some open road driving is about 6.4l/100km, car weighs about the same as the 3008.

 

I have the same engine with EAT6 box on my 2017. Around town driving average is 35mpg. On a good run A-Roads/motorways I get about 45mpg.

thanks for your help

 

I have exact same car as yours (well probably except for the color ) and I can tell you your consumption is too high in my opinion. With short distances (10km) I get around 8.5 l. Highway around 7-7.5 if my average speed is 130-140 km/h. With 90 km/h you should get 5 l. Here in The Netherlands highway speed is now limited to 100km/h (from 07-19h) and with this speed I get around 5.5 l/100km.

 

I have 5008 with the same engine and consumption on 900 km highway up to 160 km/h,
and everyday work ( i still drive to office) on normal roads. Combined consumption is at the moment7.1 litres/100 km. Measured is 900 kilometers.
I belive i can still lower the consumption regarding cold mornings and winter tyres.

 

Trip I did to Sydney (AUS) yesterday. Mixed motorway and city driving.

 

The average for my 1.2 EAT6 is 42MPG, that's on short runs. So happy with that and the overall Performance!

 

I've now done 900 miles in my new GT Line 1.5 diesel EAT8. Mostly short 1/2 mile commutes. Averaging 42.6mpg. Well below my old 1.6 diesel manual, which averaged 50.4mpg over 3 years, doing the same trips.
