It is amazing on fuel, I've driven it very hard around town etc and I cannot get it lower than 44mpg. I totally stand by my initial post that these 4cyl N47's in any guise cannot match a relaxed old school 6cyl. I bet the new 3cyl diesel barely beats the 4cyls in the real world. And my M57 will be more reliable hands down.
