I get about 28.8 mpg on my
and it is well maintained .
Don't forget this is a petrol car and is also quite heavy as you do have the initiale .
I drive a petrol volvo at work with a similar engine and get low 20's::::
With this engine it comes into its own on the motorway you should be able to easily get about 130 mph out of it I have also noticed that it pulls really well up hills .
Mine pulls at a steady rate right through the rev range I feel the engine has allot more power to give but I feel renault maped the engine to give this ride .
If you had faulty plugs you would get a misfire . I would not play around with the engine as you are likley to throw your
into a spaz
Just enjoy the luxury ride the initiale spec is great great value for money the only problem is you would always want this spec
when you change to your next car .
Mine does 0-60 in about 9secs for your info and I have had mid 130'out of it with some left in the engine .
