Question about mileage?

I might be taking a job that would require me to commute about 80 miles each way 3x per week I'm just wondering what you guys are getting for mileage per tank out of your X3 with all of the engine options for highway mileage. I'm most curious about the diesel, I'd like to know what it's passing power is like because these are 2-lane highways with oncoming traffic so if I pull out to pass, I need to know that it has enough pulling power to complete a passing maneuver safely.

Thanks!!!

The only diesel available in Canada is the 28d. It's vastly inferior to the 30d available in Europe. It's pretty slow (0-60 takes 7.8 seconds, according to Car And Driver) and many journalists have complained that the engine feels unrefined in the car. I test drove it, and while the low end torque was ample, and I'm sure the mileage is better, when you really put your foot down you're met with pretty seriously turbo lag and almost no top end power.

The 28i (the one I ended up buying) is pretty good on the highway. At 110 km/h I can maintain about 27 US MPG (about 8.7 L/100km). City/suburban driving uses more gas (I get 12L/100km, or 10.5 if I drive in eco-pro like a grandmother). The 28i can also do 0-60 in 6 seconds flat (according to a recent review of the 2015 28i xDrive in MotorTrend) and has a lot more passing power at highway speeds. These are very respectable numbers for a 4200 lb vehicle.

In the end, though, you're talking about a $50k++ SUV. I wouldn't take the diesel over the gas model for a small savings in fuel. It will take you a long time to make up the $1700 difference between the 28i and 28d models. The 28i is a much faster car with a quieter engine and far less (almost no) turbo lag. It's engine (N20) has been called one of the best 4-cyl engines on the market and I really think it's the sweet spot for value-meets-performance for North American X3s.

(On the other hand, if I lived in a country where it's available, I'd take the 30d or the 35d in a heartbeat).

for that kind of commute, I would get the diesel any day, its a highway cruiser . Mine returns 34 mpg on good days . Passing power is good when you floor it a bit and it needs to step a gear down or sometimes two you will have no trouble in that regard.

34 mpg is pretty good, I wonder how the diesel engines do in the winter though. Our winters are pretty harsh, -40 degrees with what can get to a -50 wind chill. At that point it doesn't matter if its celcius or farenheit, its damn cold.

If this opportunity works out I'm going to test all of the engines and see which one I like best and take it from there.

Thanks for the help.

I have a 2013 X3 35i, had it for about a year now. I live in Minneapolis. I've tracked every fill up since I got it with gas cubby app. So far I'm at an average of 22.3 mpg. My round trip commute each day is 40 miles, about 60% highway/ 40% city. I've taken some longer highway trips at about 60-65mph and got 27 mpg. For a turbo 3.0 liter six cylinder I've been quite happy with the mileage.

On my 2015 X3 28i I get about 19.8 MPG, but I am a spirited driver.

I'm getting 20.2 mpg. And that's babying the car. Mostly urban driving, with a bit of highway.
