how fast is it?
 

I heard that the 2001 x5 is the fasted 4.4 out there. 15.1 in the quarter mile isn't half bad. what is the Q/M time on the 4.6?

not sure about 1/4 mile times, but my old 2003 X5 4.4 with sport was able to do 0-60 in 6.8 sec

Well the current 2004+ 4.4 gets a 15.1 quarter....so I guess not much has changed.

Are we talking real world times or BMW published times? dragslips.com should have some actual 1/4 mile times posted.

I have a 2001 4.4 Sport and its fast. From a standing start I stayed ahead of my buddy driving a 2006 FX45.
I'm not to sure of times though.

Was well worth trading in my old 1999 4.0 cherokee.:thumbup:

how fast is the 2001 3.0?

I would have to say 16.5

It is pretty identical to my mom's 2006 highlander in terms of speed and my old 01 maxima.

Great question, I have a 4.4i 2001 X5, my buddy did the 0-60 check and we came out with 6.8 also, to be honest it was at 6.789 sec. I'm guessing that the reason why the times are so close together is if you look at the weight on the 01 and any other X5 the 01 weighes a little less then compared to an 04-06... Checked it out with my buddy... So it could be a possibility about the 01 being the fastest 4.4i... Now with the 4.6 or the 4.8, I would have to say the 4.8...but 4.6 not really that far off...

OK I'm confused. My '01 had 282hp, '05 has what 315hp. So why/how is the '01 faster? Torque. (girlie question).

Probably the torque and the gearing, but if you look at the BMW times the X5 from 2001 is no faster then the 4.4 valvetronic....

plus the valvetronic has better MPG, so you have the best of both worlds. :)

I also have the same sensation. The older 4.4 amazing! The facelift seems to be underpowered. It should be the valvetronic effect, speed progressive and not all the power starting from 0

Yeah, I noticed my '01 is gone when my '06 is still thinking about it. The Dinan S2 upgrade brings the '01 up to 315hp. I really ought to get some times clocked. The '06 has that startup hesitation and is way too quiet. I see a Dinan upgrade for the '06 in the near future.

I don't quite agree the 01' accelerates faster or has the same 0-60 as the 04' models:tsk: . All the reviews I read about pre 04' 286hp models said 0-60 in 7.5secs while the 04' 320hp does 0-60 in 7ses. To be exact the times mentioned above are 0-100kmph, which is 62.5mph.

I have heard that 01' owners thought the 04's drive was slower but I have whooped my friend with his 01 4.4 starting off from lights a numbers of times.;)

I have about two weeks owning a 01 4.4i and I know for a fact that it'll do 0-60 in less than 7.5sec:confused: No mods from previous owner that I know of.

So if my 06 4.4 FEELS slower than my 03 4.4, that is only the way it feels? Less torque, but same or more power?

Gear ratios...

How do you know for a fact that it's less than 7.5???

Torque, gearing, power etc. all have a big part in the feel and actual quickness and speed of a car. My 03' 4.4 - sport certainly feels quicker than my friends 06 4.4 sport. We both agree on that, and when we've raced (not really race, just took off quickly from a light) I generally 'beat' him regardless if I'm driving my car or his. I believe the speed differences are nominal at best (I don't know this for sure), but IMO the 03 just 'feels' better to drive.

Just looked up BMW released data.

Torque: 01 : 324 at 3600 rpm. 06 : 324 at 3600 rpm -> same torque.
curb weight: 01: 4795 lbs, 06: 4927 lbs -> 01 is 132 lbs lighter.

It seems 01 has advantage on 0-60 time.

5sp vs 6sp auto. ratios are different and you have to make 1 more shift on the 05.

I have a 05 4.4 and went to the Infineon Raceway quarter mile drag strip. I got to run two times, the first time I got was 15.486 and the second time I got was 15.542. The temprature was 80 degrees. I also thought that my X5 was slow to act, right when the green signals me to go I stomp on the gas but it hesitate for a second then it goes..

It shouldn't matter at the raceway because the time doesn't start counting before the car moves...

I hate tranny hesitation on new models... Anyone got a tranny software upgrade?

some older models may not show the full potential, due to the wear and tear issue...maintainance plays a big role and could be hard to compare an 01 in 2006

I posted before, maybe May. BMW has a V23 upgrade for 06 pending. 05's already have an upgrade available. Many have posted their 05's did better with the upgeade. I will get the upgrade as soon as is available. May be better info in search here.

Ok, I've got it. On page 88 of the BMW Car magazine September issue, you can find specs of all the X5's. It shows that the 286hp 4.4 (pre 2004) does 0-62mph in 7.5 secs while the 320hp 4.4 (post 2004) does 0-62mph in 7 seconds.:nanana:

I have been reading Car and Driver magazine for approximately 20 years and they seem to have the fastest test times posted for vehicles. I also prefer independent data to the manufactures.

The two links below are for a 2002 and a 2004 X5 4.4s. I think the 03s had a HP increase to 290??? I'm trying to find the issue.

I have an 04 4.4i with 20k miles on itand my cousin has an 01 with 60k miles on it. We raced 0to maybe like 70 or 75 and i had him from the start. We were even at the start for maybe 50ft then i pulled away from him steadily after that. But we raced on the highway also from like 65mph to about 120mph and my 04 was alot faster than his at those speeds. the valvetronic topend smokes the non valvetronic on top end.

The valvetronic replaces the throttle body for limiting engine speed. Though the valvetronic is more technically advanced than a throttle body, it is less responsive to rapid changes like flooring it off the line. Once at speed the valvetronic breathes better than a throttle body and adds horsepower. I doubt you will see valvetronic M engines.

I agree and Bmw has already said there Mcars will never have valvetronic

Finally someone that agrees with me.:)

I don't recall any increase in HP until the facelift. At least not in the Euro specs. Always 286hp.

Um, um um.......
 

Um, because I floor the peddle and know what 7.5sec feels like:nanana: By then I know I'm doing more than 60mph:thumbup: I haven't had the chance to drive it too much since I got her but I'll be taken her down to ATL motor speedway in the weeks to come. I'll report back official results of the 01 0-60 times;)

You're trying to say that you "feel" the difference between 7 seconds and 7.5 seconds:confused:
Two of us on this thread have said that our post 04 4.4 X5's beat the pre 04 models.
Looks like you'll have to find yourself a post 04 4.4 to race to find out the truth about which is faster;)

The 2003 4.4 engine specifications listed in my owners manual are……

290 HP @5400RPM
324 Maximum torque ft/lbs @ 3600RPM

A dinan performance chip will help all the valvetronic models out a great deal. The throttle response with a dinan chip is comparable to an M car. Then the pre 04 4.4 wouldn't stand a chance.

Uh, which M car were you thinking?

Guess I can't be sarcastic up N here with the post 04 4.4i guys:rolleyes: Taken offense ehh? J/K. Anyhow, I'm not saying the 01's are any faster than the 04's but com'on you and I both know what 7.5 sec's feels like. Who needs a stop watch to tell em that?:rolleyes: I haven't gotten official times/results yet but in the weeks to come hopefully I will. But on the real, I could give a rats ass on the 0-60 times the 4.4i X5 is doing. It feels, and looks fast therefore I'm content with all that. Nuf said:nanana:

as far as my G tech pro is concerned. the best time i ever ran 0to60 in my 2004 4.4 was 6.779 so i will call it 6.8sec. Which is about right.The g tech is very accurate to the tenth i verified this at the track against my time slips. It was off a tenth at the most. and no one knows what 7.5 sec quarter mile feels like. If you did 2 runs and on was 7sec and the other was 7.5 i dought you would even feel it
