X5 35d MPG not significantly better than M3?

ajvee · 08-29-2013, 09:40 AM

Chaps,

I drove a loaner X5 35d into work today owing to my M3's throttle actuator issues. I do tend to lead foot it, and I was pleasantly surprised that the X5's MPG over my 40 mile highway commute (21.3) wasn't significantly better than my M3's MPG (20.1).

Am I missing something here guys?

Hope you guys are having a wonderful day

I test drove a used one the other day and the avg mpg said 21

lsal · 08-29-2013, 11:20 AM

I wish I got 20...

You aren't driving the M3 right. 20 mpg is a no no.

You live in Georgia. How much traffic do you guys have? Come to Manhattan and go for a drive, then talk to me about mpgs lol.

You aren't driving the two cars the same. Leadfooting the X5 and babying the M3. I struggle to 22 on the highway in Indiana where it is flat... Much less city driving (14-15)

I have a 335d and it gets about double the gas mileage of my M3 in just about every kind of driving. I did a full track day once with the d and it only used a 1/4 of a tank, lol.

I'm certain the Diesel engine gets better mileage than the M3. It all depends on your driving distance and highway or stop n go traffic usage. But regardless it'll be more efficient than an M3.

I had a diesel for 24 hours. Driving quickly it was around 21.5-23.5mpg, driving conservatively but not slow (10 over, not rushing for red lights etc.) I did achieve 25.7mpg with 3 passengers on a 10-15mile trip to dinner.

It's all about how you drive, conserving gas is a skill for a driver as well.

My x5 35i got a lifetime mpg of 21. The x5d is limited by the 6spd vs 8 on the gasser.

RedGT3 · 09-01-2013, 05:40 PM

We used to get about 21 mpg with the x5d now with the x5m only about 16 mpg

1MOREMOD · 09-01-2013, 06:11 PM

thats not much better than the 18 avg i get in my regular x5. wanted to trade up for the extra torque and better towing capability. thought it would get more like 25 freeway since i can get 20-21 with 20s on my x5 3.0

pbonsalb · 09-01-2013, 08:12 PM

We averaged about 15.5 in our mixed city highway with our 08 X5 4.8i. Our current 08 535xit gets 21.5 average. My 08 M3 averages 19.5. I think a diesel X5 would be great but am not sure the new ones with urea injection areas efficient. The X5 35i with newer 8 speed auto may be the way go go, plus the twin scroll turbo is more efficient than the twin turbo of a few years ago (like our 08 535xit).
