    Re: Fuel consumption current model 523i and 525i

    My 523I F10 also very thirsty, thinking to remap the ECU. As mentioned by OBD the tunning increase power n torque at the same time REDUCE FC.....

    Re: Fuel consumption current model 523i and 525i - please advise

    On my 2004 525, I am getting about 8km/L (30% city /70% highway) but now with jams on our highways almost during the day/and even some times at night..... I think its more like 50% city and 50% idling....)

    IMHO, if concern about FC, please forget about BMW.

    BMW (especially 5) is a heavy car (around 1.5 ton). It will definitely drink a lot in the city with start-stop traffic.

    Re: Fuel consumption current model 523i and 525i

    E60 is 1.7 tons there about. My >4 years old 525i does about 7-8km/l when doing 70% city and 30% highway, but the FC improves dramatically to 10-11km/l when doing 70% highway and 30% city. And for 90% highway like driving to KL, it only consumes half tank from Tuas to KL city centre, i.e. >12km/l.

    If want good FC, get a Toyota or Lexus. They are very frugal on fuel when driven normally (light on the accelerator). But what is the point, the drive will be dead boring without the handling of the ultimate driving machine.

    E60 cannot be 1.7 ton unless 550 loh. If 1.7ton, N46 no power man.

    You're right. E60 is not 1.7 tons. Just check the owner's manual for 2006 specs. The kerb weight is 1570kg for an auto 525i without options but with 75kg load (about an average adult male) plus 90% full tank of fuel. So with options such as adaptive headlights, pro-nav iDrive, etc plus barang barang (mobility kit, car care stuffs, vacuum cleaner, touch light, emergency use water and engine oil, etc) and me being overweight, think probably at least 1,650kg for my E60 I guess.

    That's why i keep my car wif as little as things as possible. Every kg add to the car will reduce its performance.

    Just asking, how much is your monthly bill alone on fuel?
