So is it fair to say DHP on xdrive brings it close to RWD handling?

Is the mere difference to in RWD is that you can go sideways?

I'm not sure I'd say it gives it RWD handling. More that it gives it a firmer suspension and sportier handling. xDrive is RWD biased, 60% rear, 40% front, with the ability to instantly transfer 100% of the power to either the front or the rear based on what the conditions demand.

Tires are also important. xDrive cars come with low rolling resistance all seasons by default. To get the best handling and performance you need to get the no cost (generally) upgrade to summer performance tires.

Yes Bmw xdrive is a bit soft but almost all supercars are going 4wd/awd now including M cars.

It comes to personal preferences and skills. If you got no skills, a 400hp rwd will just end up in a wall.

100% to the front?

I don't think so???

Also not true it can go 100% rear

Maybe there are split seconds where the Ediff needs to lock the front but that doesnt make it a rwd lol

True, 100% to either the front or the rear. http://www.bmw.com/com/en/insights/t...mm_xdrive.html

"xDrive is the permanent all-wheel drive system from BMW: under normal circumstances, it distributes driver power between the front and rear axles in a 40:60 ratio, and changes this figure variably when the road surface or overall driving conditions change.

Acting virtually instantaneously and a manner so subtle as to be go virtually unnoticed by the vehicle's occupants, xDrive can direct up to 100% of drive forces to one axle."

Sounds like a pretty good system then. Yet Quattro is considered better....

[Blubaron79]

No

[DarrenL_007]

Search xDrive vs Quattro on YouTube and you will see surprising results in favour of BMW.

... because it can torque vector upto 100% to any one wheel. The bmw system can only do 100% to the axle.

This means the quattro system can under and over steer in the corner while under power

Except that it usually understeers. A lot

as does the bmer system. The RS versions are better.

Yes - If you are a hard core enthusiast and need xDrive, the consensus is that you should order or try to find a vehicle with DHP. The majority of folks will be fine with the standard suspension on the M-Sport xDrive.

With regards to Dinan, there are a few suspension-related mods. There are springs, anti-roll bars and the Dinan Shockware which is software suspension tuning for those that have the Adaptive M suspension.

Only the high performance models have torque vectoring. The lesser models that the majority of people buy don't have it.

yep. that what I'm talking about. not the versions with Haldex clutch system giving occasional awd.

Yeah our RS4 was rather fun.

Watching the adverts on the new RS3, wondering if can get the dog in the back lol.

Oodles power for a hatch.

Something like 360bhp and 0-62mph in 4.3 secs.

+1

You guys now have got me thoroughly confused (which likely is my fault, not yours). How does this current thread compare with the guidance I received in this recent thread:
http://f30.bimmerpost.com/forums/sho...php?p=17955945

Is it fair to say that in certain conditions up to 50% of the power can be distributed to the front axle, but 100% of that 50% can be delivered to a single front wheel?

Thanks

I don't know, I have yet to experience understeer in my 435i xDrive. If anything it oversteers then instantly shifts power to the front to stop the rear from kicking out; effectively stopping the slide. Doesn't mean it understeers. Had a RS4 & A6 Allroad Quattro, both used to understeer more than oversteer.

No. xDrive has the ability to send 100% of the power to either axle, regardless of the mechanics of how the power is delivered to the individual wheels.

for me depends how your geo has been setup and how you approach the corner. I tend to find if I go into the corner with a balance throttle after braking it understeers if I have not scrubbed enough speed off . If I trail brake or have to much throttle on it may over steer. The EVO 6/7, after braking you just mashed the throttle and pointed the car. The torque vectoring would understeer in and oversteer until the car was on the intended line. The 997.2 awd with vectoring does the same. sweet
