It's been some time since people started taking delivery of 2011 35is. The 2011 models have an EPA estimate of 25 MPG on the highway. There has been debate on these forums about the accuracy of EPA estimates with gas engines as well as diesel. Perception is, diesels are underrated and gas engines are over rated w.r.t MPG. Is it true in real world driving though?

Calling all 2011 X5 35i owners to share their real world MPG figures -- city/highway/combined, before break-in and after break-in.

I had the opportunity to do an extended test drive with an X5 35i sport activity package with the 20" wheels. We picked it up on Saturday late afternoon and returned it on Monday noon. It was brand new and we put up about 100 miles. We average 16 MPG in mixed highway/city driving (about 50/50). I tested the mileage on highway in town for 10-15 mile stints with cruise set at 70. The average over those stints was about 22-23 MPG (lots of overpasses and some slow downs because of traffic). I suspect the 20" wheels didn't help mileage.

With my wife driving: Flat highways can get 25-27mpg. City is around 14-16mpg. Overall 17-18mpg.

When I'm driving it, I get 12-14mpg :D

That's interesting since I have always averaged 17.5 in my 2008 X5 3.0 and was hoping to gain at least a couple mpgs in the new 35i Premium, even with its 19 inch wheels....

25-27 MPG is good! You get 12-14 MPG with your driving on the highway!?
I get 12-14 combined... I drive in manual mode and I hate the acceleration on the 7th and 8th gears :D

My wife's commute to work involves stop and go traffic in the morning (like city driving), but she uses the interstate on the way home. I'm guessing she's stuck more in traffic than on the interstate, hence the mpgs. Plus the 35i Sport does have the heavier 20" wheels.

If I drive the X5 gingerly, I'm sure I could be close to 19-20 combined...it's just not fun that way.

Too early to really tell, but defintely on the wrong side of the EPA ratings. On road at 75, about 19 mpg. ope this will improve after a few more miles.

I read some where online that 2011 X5 35i EPA ratings are 17/24 but the dealer's website indicate 15/21 (same as 2010 30i models). BMW website doesn't seem to show EPA ratings.
Any more real life updates would be helpful.

Thanks

Well I went ahead with my original choice of Diesel after reading through the responses above, and I don't regret it :). Depending on how I drive and if I am going uphill or flat I get 24-28 mpg highway *before* breakin.

One thing about the diesel and turbo lag -- diesel is not exactly fun to drive in stop and go traffic. I can definitely feel the turbo lag. My old gas sentra can beat the X5d at start off. But on the freeway diesel is a different beast. That is where you feel the torque. You fee like the king of the road, that too with good MPG. More over, you can find diesel fuel usually at 'regular unleaded gasoline' prices -- about 20cents cheaper than premium gasl around where I live.

And the 35d will never be as fuel efficient as a Prius, so what's your point? Lol. :confused:

the 35i and the 35d cost roughly the same though - you'd save 30K on a prius LOLOL :rofl:

Hmmm...looks like there isn't any actual mileage improvement on the 2011 X5 35i vs 2009/10 X5 30i. My brother's 2009 X5 30i averages at 19mpg and the 2011 X5 35i doesn't seem to do any better although EPA numbers favor 2011 model :(

By the way - good one Aqua Bliss..LOL...

WOW!

Around the Southeast (FL, GA, NC, SC) it runs the same of a few cents higher than Premium.

I filled up the other day at $2.82 (Prem 2.79). As of today diesel's up to $2.89.
