Great video.

Once you own one, it is hard to step backwards!

I have climbed up on to a 4 foot snow berm, and managed to get up, and over it. All w/all season tires, and with X-Drive!

What x doyou have?

No question I am a BMW fan, but I would bet money the ESP was turned off on the q5 and that's why it failed.

Maybe you are right or maybe it has something to do with the power transfer from back to front and otherwise!!

Isn't it to hursh?? My sister has bmw x5 from 2004 and is kind of stiff compared with my e 60!!

+1

poggy · 10-24-2010, 09:21 AM

so what's the point of an Audi Quattro?!

Park2670 · 10-24-2010, 09:24 AM

Audi Quattro isnt as advanced as they make it out to be. X-Drive is the only system out there that can transfer 100% of the torque to either front or rear axle.

woodman650 · 10-24-2010, 09:28 AM

Now let's see the same cars in the same test, but a video that Audi has made

kmarei · 10-24-2010, 09:37 AM

looks suspicious
i always knew, and seen quattro to be better than the xdrive

I might be wrong, but Haldex version Quattro (one of Quattro systems Audi is using) can transfer maximum 100% of the torque to the rear axle. In normal condition distribution ratio is around 95%/85% front & 5%/15% rear though.

I have been taught many times that it cannot transfer 100% of the torque to one axle. Wikipedia says the same.

Quote:

The nature of the Torsen is akin to that of a Limited Slip Differential in that, rather than actively allocating torque (as a computer controlled clutch can do), it supports a torque difference across the differential (the Torque Bias Ratio (TBR)), from the side with the least grip to the side with the most. Hence by nature the Torsen is limited in the amount of torque that can be supplied to the axle with the most grip by the torque available at the axle with the least amount of grip. Therefore if one axle has no grip, regardless of the TBR, the other axle will not be supplied substantial torque. In the extreme, for a centre differential implementation, complete loss of traction on a single wheel will result in very limited torque to the other three wheels.

I think the audi's ESP is turned on, but the audi's differential needs torque to make it work... So no torque, no lock.

+1.. had both a4 and Xi. Quattro's much better especially in the snow. But BMW claimed the Xdrive is much more advance than Xi

haha very true. you never know what kind of tires each vehicle has. for all we know bmw could've put winter tires on the x3 and performance tires on the q5. i would believe it if i could see it in person and see what tires are on the cars

Maybe you had an early version of the x-drive? All the reviews I have read in the press in recent years have rated the x-drive better than the quatro.

madfast · 10-24-2010, 10:43 AM

this video is all marketing. it is widely known that quattro fails when there is zero resistance. the only time you would ever be in such a situation is if the wheels were lifted off the ground. even on ice you have enough resistance that this situation would never occur.

bmw shows you the superiority of their system with a situation 99.999% of us would never actually see in the real world...

bmw = masters of marketing

nissan's ATTESA awd system works basically the same as x-drive. the GTR can have up to 98% tq to the rear wheels if im not mistaken.

quattro (non-haldex) is a very, very, very good system. this video is a bunch of marketing crap that has no real world relevance...

Real world situations please.

And tested by a 3rd party please.
