2015 X5D initial mpg numbers

[skalberti]

The first 140 miles in 100% in town driving with absolutely no highway driving is 23.9. Reset the mpg display and went on a 220 mile interstate trip with about 30 miles of pretty steep hills driving 70-80 mph today. Averaged 33.9 mpg. We've had the car 2 weeks and are still on our first tank of gas. I'm impressed with these numbers. Especially since the car isn't broken in yet, so I'm confident they'll get a little better down the road. What's your 2015 getting?

I've gone about 700 miles, with a city/hwy split of about 65%/35%. This is almost entirely Comfort Mode, as I tend to exceed the break-in recommendations when I use Sport .

As for mpg, it depends on which source is used. If I calculate based on how much diesel I pumped for those miles, it comes out to about 20.25. The trip computer calculates it as about 23.5.

I'll probably take a longer hwy trip next weekend and see how that stacks up.

One item to note is that this is Florida, so the A/C is working very hard pretty much all the time. Not sure how much A/C affects engine performance in modern cars, but thought I'd mention.

One other note is that this is about 7mpg better than my 35i was getting after 3 years' driving with the same city/hwy mix. Given that premium and diesel are about the same cost here in my area, that's an improvement for me.

Yep, we're coming out of 2012 35i. Got 16 in town and 24 with a strong wind at our tail. So far we've driven 359 miles and it's sitting at 1/2 tank. In comfort mode with the AC on. It's been in the high 90's in Arkansas with high humidity. That's about a 32.6 mpg tank average. We have no complaints or regrets switching to the D.

Good numbers! I'm betting they get a tad better after a few thousand miles.
