Just wanted to let you all know, just drove my X3 30 from Philly to Marathon. Very comfortable. But after 6 hours, your ass will get sore. MPG for that run was 33-34 mpg.
Now going from Marathon to Key West (lower speeds)… 42MPG!
Never thought it possible. About 700 miles to a tank!

Yes BMW’s do squeeze out great MPG & from the tank. However you probably will see that if you do the math when filling up the tank, that BMW’s computer calculations are a bit overly optimistic than your actual will show. Still great MPG when compared to it’s competitors but not as high as the dash shows.

I got right at 40 mpg yesterday on a 39 mile drive. Best I’ve had yet. Kept close to speed limits and on efficient mode. I was testing switching modes verbally. “Hey BMW…. Efficient mode “. It worked. I prefer the button on the console of my F10 to the menus, but I can get used to this also.

Yes, I felt the same "shocking" way when I moved from my 2004 MDX (15 mpg) to the X3 m50

Modern BMWs are great on MPG! Something Prosche and Mercedes are having issues keeping up 😆

I got a similar mileage over the weekend on a road trip. 19.1 km/l translates to approx 45 MPG.

On highway trips without traffic of course results are better. Mine is just daily drives resulting over 1100km.

For UK members, the Honest John Real Mileage UK website is a data point for BMW real world MPG reported by users across different models. Unfortunately, there is no data as yet on the G45 or some of the entry 2.0 MHEV previous gen models.
I’ve always been impressed with the report MPG of my car, given the performance on tap, and the fact I don’t use Eco mode or drive like my granny.

I drive is sport individual mode most of the time, and just flick the shifter to engage/disengage sport transmission mode. Average just over 50mpg UK on motorway centric journeys of any distance. I can’t recall what MPG I got from the G45 M50 I had for a week.
Unfortunately I’m addicted to torque, and that doesn’t help mpg lol

Whist I didn’t take the numbers down, the M50 MPG wasn’t as good as my current X3, but I wasn’t expecting that.

I don’t see a G45 in my future if that puts your mind at rest, but the new iX3….. who knows.
