1. Cyee, firstly let's ignore the computer. When next you fill you up, reset your trip meter and note how many litres you've filled, then before you run empty take note of the kms driven, and then calculate the consumption.

2. Now not that I don't believe you, but it's very difficult to see how you could be keeping the revs <= 2000rpm, especially since the autobox habitually revs well over that amount before changing up.

3. Again, solely driving in town will take its toll on economy big time.

4. Have you tried the Manual mode yet?

5. Do visit your dealer if you think something is wrong.

Cyee, I too had the same concern previously. But the onboard computer is real-time. You'd need to manually calculate it. I'm having the same specs as you and it's solely city driving. I'm getting between 6.3 to 7.3 km / liter. Not the best.

7.2 km for every 100 litres of petrol is a bit excessive.

Do you mean 7.2 L/100km (which is very good particularly for a petrol engine) OR do you mean 7.2km/L (which is 13.3 L/100km and probably about right for a petrol engine driven hard)?

I drive an xDrive20d automatic and get 7.5 L/100km (nearly 40,000 km travelled)

all X1 drivers:
take a look to www.spritmonitor.de and you will see a very good overview of all consumptions.

A engine with 1100+ Km is still very new. Relax and let the engine break in. Come back and check with us when you reach 3000 Km.

At the same time, if you keep driving below 2000rpm, the engine will take longer to break-in. Just drive normally.

How about your tyre pressure? Could it be under-inflated?

But if you are really that concerned, you should go back to the dealer and ask. Make full use of the warranty!

Hi Cyee,

I agree with everyone else here:

1. Zero the trip meter as well as the consumption meter, they are two separate things. If you have not zeroed the consumption it will give your overall figure from new
2. Better still, work out your consumption manually to check accuracy
3. Wait a few more 1000 km for the engine to settle down.
4. If the consumption is still excessive, take it back to BMW to have it looked at.

PS: Where do you live? What altitude are you at and are there many hills on your route?

Normally around 2000 km to settle down the new engine and should get better fuel consumption ?

It depends. 2000km is not a magic number, so don't bet on that. But in general, the more you drive, the smoother the engine will become. You will feel that the engine will be more willing to rev.

I suggest do not worry too much in keeping the rpms below 2000. By doing this, you might need a longer time to run-in the engine. Just drive normally and keep it below 4500rpm for the first 2000kms, as stated in the manual.

And from a few posts above, melts mentioned that he is getting 6.3 to 7.3 km/ L, which translates to 15.9 to 13.7 L/100kms with city driving. So not far from yours as well.

Better modify the way to calculate the consumption

I suggest:
1a. RESET the trip meter (or note total kms driven) right before fill up
1b. fill up (no need to record this number)
2a. NOTE total kms driven since last fill up, say KM1, right before fill up again
2b. fill up and RECORD fuel quantity, say L1
3. calculate consumption as C1 = 100x(L1/KM1) litres per 100 km
repeat above a few times to get an average consumption

wait another 2000km for an exactly view on it. If then the fuel consumption has'nt turn to normal, your car is not equal to the promised properties in the technical datasheet of this model. If your dealer is in the following not able to fix that issue, insist on undo this purchase.

Fliegenfranz - I have an X1 sDrive18i too and drive at altitude, I do think the technical specs are optimistic. If I'm brutally honest this engine is underpowered for a heavy car like the X1 - it's nearly 100kg heavier than a 320i. Do remember this is a petrol engine, not diesel. What aggravates Cyee's consumption is that he only does urban driving.

Having said that Cyee's consumption is very high - I would certainly visit his dealer right now.

To further assist, we both have automatics and I use the Manual mode to save fuel - it definitely helps as I change up earlier than Auto would do, with no performance hit in normal driving.

I would second the j128i's post and add that I also noticed (twice that it's stated in specs or even more) fuel consumption in city driving. Seems like the car consumes a lot when driving on low gears but the automatic gearbox does not forcibly shift the gears up when you do short-distance (start/break-in) driving. On long-distance driving, when on highways and I can drive with a constant velocity (and what's more, acceleration) the digits are more than okay.

yo cyee chillax bro, wait till your car hits 3000-4000km it will change automatically to less than 10L/100Km. if it doesnt then take it to your dealer. when i got my car it showed 30L/100KM, then within few days it went down to 16L/100KM, after 3 weeks now its around 9.9L/100KM.
