I realize that I only have 1200 miles on my 545 6 speed but I wanted to see what kind of mileage others are getting. If I remember correctly my sticker said 17 city 26 highway (or something similar). With hard driving I am getting 18-19 city and well over 30 on the highway (300 mile trip averaged 32mpg). The highway figure is better than my previous 2001 530 5 speed.

Anyone else seeing better than advertised mileage.

 

Those mileage numbers are great! Are you computing the mileage yourself or using the computer readout?

 

Using the onboard computer

 

I got about 20 mpg average on my 545 with fairly aggressive driving mixed between city and highway.
