Welcome to Bimmerfest.com! I've moved your thread over to the X5 forum. I would think the 3.0l would be the most economical for fuel but perhaps an X5 owner can chime in.

Good luck,
Tim

Your year of choice (02-04) will include 2 version of the E53 X5, (pre-facelift 01-03 and facelift 04-06) Maintenance history is very important and have a PPI (Pre-Purchase Inspection) at the $tealer.
3.0d is hard to find, 3.0i is much easier.

If you can get a diesel X5 then that's your best bet on fuel economy.

Don't get a V-8 for various reasons. (4.4, 4.6, 4.8) And I would do some research on an X3 unless that's just too small for you.

No diesel here in the states but 04 - 06 4.4i does about the same as the 3.0 gas maybe the 3.0 is 1 mpg better. I average 18.5 mpg and 21-23 on the highway (US Gallon). Driving the 3.0 is o.k. but driving the V8 is an experience! No comparison. I think in a lot of instances the V8 uses less fuel because it doesn't have to work nearly as hard to get to speed and maintain it plus you have the 6 speed automatic vs. the 5 speed automatic. You could probably do a bit better with the manual 3.0 gas but not sure. There is so little difference in fuel economy between the two that I would always pick the 4.4i! I don't really know about the 4.8is. Good Luck!

The 4.4 and 4.8 actually have better fuel economy than the 3.0. I know that sounds crazy. I didnt believe it myself but its true. They do 1 to 2 mpg better than the 3.0. You can do a search and see. I would also go with the 4.4 or the 4.8.

Mein Auto: X5 e53 3.0i 2006
Go for a 3.0i. It will do about 11-13 Ltrs per 100km city cycle on average and should cost no more than $35 per week for average fuel consumption (Australia). I have a 3.0i 2006 and love it. There is enough power to haul a long trailer or caravan, and the car by itself is relatively quick off the mark when acceleration is applied, and purrs and comes into own with speeds beyond 150km/h. However, try and get a later model 2005 or 2006, and make sure it has a complete service history with Authorised BMW service mechanics, otherwise it will be $$$ !

I recommend the 4.4i, 4.6is, or 4.8is. IMO the fuel savings of the 3.0 isn't worth the decreased performance.

The 4.4i was offered every model year you listed. Horsepower of the 4.4i was increased in the 2004 model year. The 4.6is and 4.8is are higher performance X5's which included many options standard. 4.6is was available from 2002-2003 and the 4.8is replaced it in 2004 and was available through 2006.

Mein Auto: 2000 X5
I agree with some of the other posters however it comes down to personal prefference. I have a 2000 X5 with the 4.4L and I absolutely LOVE it you cant compare the performance aspect of the V8 and the fuel econmy is pretty close in comparrison. Good luck on your search, hope this helps.

Mein Auto: X5 e53 3.0i 2006
Interesting thread this, particularly with respect to fuel consumption of the engine variants for the e53 series. I know my 3.0i needs more acceleration to get going because the x5 body and it's multitudinous parts is heavy and requires power from the engine to get it going, whereas the v8 would do this with less effort and save on fuel. Fuel consumption is a big factor when purchasing a car! What you save in petrol can be in the 1000s per annum, and what you save can go towards paying for cost of service.

It is down to practicalities. If you need your car to haul the family around on weekends and there is a big dual wheel caravan that you take on country holidays, and this car is also needed for quick overtaking of other vehicles on the highways to get to work on time, then definitely v8 is the go definitely, as you will find the 3.0 a bit slow off the mark, and you will be burning the fuel with all the stopping and starting @ traffic lights.

If, however, your use of the car is less demanding, such as weekend use essentially with a small family such as mine (1 child) and the occasional country trip with a small caravan, then the 3.0 variants should save you on petrol in the long run, and believe you me, beyond 120 km/h, the 3.0i just hums and burns less than 10 ltrs per 100km.

It is a known fact that all BMW cars "sing" and feel very comfortable at high speeds because they hug the road with their racing class stability and there is no vibration. It is part of the reason why BMW cars are expensive to buy and service, as it is all those wonderful parts working in unison to create the magic.

get the 4.4!! I have a 3.0 and I compared gas consumption with my friends 4.4 and his is a lot better! The 3.0 I6 always has to work hard and rev a lot but the low end torque in the V8 suits the X5 a lot better! And btw look for a face lifted version..looks better!

I will be renewing my x5 in a few years, and will remember this thread when I consider a 4.4 over the 3.0 engine. If the 4.4 is so economical, The 3.0i becomes redundant after ignoring the price difference. Also, another important consideration is that the 4.4 may last longer with the reduced torque to haul the mass of the car.

Love my 4.4! Go test drive the engine variations and see what you like best. Sometimes the sacrifice in fuel costs is worth the power! Up to you.
