What is your opinion of xDrive?

I'm in the process of acquiring my 2nd Bimmer, a '07 530xi with manual transmission. I had a 5 speed E39 previously.

What is the general consensus about BMW's xDrive system? My understanding is that under normal conditions, 60% of power goes to the rear axle and 40% to the front, but that if the car senses slippage, it dynamically allocates power to the axle that needs it most. Is that a correct synopsys? Sounds like what Subaru has had for years.

My question is: does the 40/60 ratio "ruin" the driving experience in your opinion? I'm sure I'll appreciate it in the snow here in the Northeast, but what about the majority "normal" conditions? Also, I understand gas mileage for the 5 series is pretty respectable. Does the xDrive system degrade that in any way? I would have to guess that it has some impact, no?

Sounds pretty accurate to me. As for driving in normal conditions, the xDrive can't compare to a non-xDrive with sport. Unlike Audi and Subaru, theres no in-between when it comes to all wheel drive or performance handling. BMW makes you choose one or the other.


Any AWD vehicle will have a lower mpg compared to its non-AWD equivalent

I love how my X-drive handles - having said that it would most certainly not compared to a sports suspension non-X drive. The X-drive is confidence inspiring and I really don't notice too much of a fuel economy difference. I have a535 xi and these days in regular driving I am getting between 19-21 mpg (all around). On a long trip I can get up to 28 plus mpg.

You don't need it in CT. I would get a 530i Sport and invest in a second set of winter wheels with some Blizzaks. You'll regret not having the BMW sport tuned suspension if you get the XI, which makes a BMW, a BMW!

I previously owned an E39 530i (RWD) and now own an E61 535i with xDrive. The application of xDrive is seamless and transparent in my experience. It does not detract from the driving experience even on dry roads IMHO. On the track or at the limits of performance, the additional weight of xDrive may be a handicap.

The link below is to a video on cnet that illustrates the performance of xDrive.

to me, xdrive cars feel more disconnected and understeer noticably. In the northeast, most bmw's are xdrives, so when i found my RWD, i jumped on it.

I currently own an E39 '98 and 535xi '06. There are few things to consider before deciding on with or not "x"?
1) if you drive in bad weather, definitely a plus in having the x
2) if you want to upgrade the suspension, you will spend a lot more than on a non-x
3) if you want to upgrade the wheels, less options due to higher offsets but still acceptable options
4) about 15% more fuel on the x version
5) handling - same driving experience (IMO)

Good luck

Thanks for your comments, guys. Now an add-on question... Do you run winter tires with your xDrive or just rely on the same tires year-round?

Seriously, unless you are tracking the car or will be driving like an idiot all around the country everytime you get into the vehicle, the difference between X-drive and RWD with sport is moot.

I currently own a 2008 550i with M-sport package and my wife owns a 2006 325XI. I previously owned a 2003 330XI. Are there differences - of course. do they really make that much of a difference in everyday driving - absolutely NOT.

the X-drive system is great, makes the car a year rounder instead of a summer crusier. If you are even thinking about using the car all year round and you live where it is known to snow and ice frequently during the winter months - go with an X-drive system and don't ever doubt that you made the absolute best decision. Hell, my 550i sits in the garage all winter while I drive my old Jeep Liberty, as my wife passes me in her 325XI, in a foot of snow.

So, although you will hear all the pro's and con's about this and that and how X-drive sucks and steals the thrill of driving a BMW, DO NOT beleive the hype. they're all damn close to the same unless you are a freakin' expert in car handeling or race cars for a living - for us normal folk, go XI and love it.
