almost 100% city and have a/c on all the time. about 16 mpg but i only have a poor man 530 :'(. in fact, before sw update, i had less than 15 mpg but it's in the 16 mpg range after the update.

i just checked couple days ago and i messed up the two numbers, mpg and mph . i'm actually getting 14.x mpg and 16.x mph .

 

Just did the Euro delivery on a 530i 2 weeks ago. Manual. A little over 1,000 miles and the computer showed 24.6 mpg.
First time I put gas in it I was down just a hair below a half tank. 60 euros or about $80. I laughed like hell. Would have been about $150 for a full tank.

Euro delivery ia a blast. Only problem is now it will still be another 4 or 5 weeks until I get to drive it again!

 

Mixing both highway and local, I show a reading of 19 plus per gallon, if I use a higher octane of 93 the mileage goes up slightly.

 

I am at 1300 mi (so just past breakin) - normal mix is 70/30 highway and average about 20mpg - however, been off this week and doing city (read suburban) driving - can do no better than 16 mpg - from what i have been reading does it seem that the sport package has a material impact on mpg for the 545...? As per the sig, i have a 545 w/sport and 6 spd manual...

 

First 2 tanks after return from ED getting 25.6 mpg over mixed 72 mile round trip driving. I am very happy with the straight six....if you drive conservatively it gets great mileage, but if you punch it (manual transmission) it will move. My 5er gets better mileage than my beater PT (20-22 mpg).

 

Just a consideration about manual/auto tranny. Before ordering my 530d I used for one week a loaner 530d, built 2003, with a manual tranny. In one week I drove it for about 2.000 km, 70% high speed highway and 30% town cruising (in rush hours), exactly as I do every bloody business week since some years.

The onboard computer showed, after one week, 8,4 liters/100 km or close to 27,90 ml/US gallon; when I got my autotranny 530d, in one year I never was able to do better than 22,00 ml/US gallon (average consumption from day one).

With the same percentage of highway and downtown use, in the same conditions, my 535d (supplied only with autotranny) is doing a little bit better: on average, since day one, I'm getting now around 24 miles per Us gallon, notwithstanding the improved performances.

I do not complain about 535 consumption; I believe they are pretty good for the performance of the car and for my very un-economical driving style. But, apparently, there is a huge difference in consumption between manual and auto tranny: the second one is costing you, on average, at least 15-20% more fuel.

Any other has similar experience?

 

An first build 747 (747-100) sucks a gallon a second (apx 3200 gal/hour, which on the other hand transports over 300 persons 6000 miles...)
