Video: BMW X3 vs Audi Q5
 

I found this Video on the internet- could someone explain how this could be true?

PLease note the rollers on the ramp- simulates no traction on the front wheels.

Dude this video has been discussed here a thousand times. No, it's NOT true. It's a BMW dealership that made this video, and they manipulated the driving to make this happen. You can tell by the way they are trying to take the Audi up the ramp, that they are purposely doing this. Remember, Audi INVENTED Quattro. There are plenty of other videos showing what Quattro is capable of.

Best answer look at this

ESP was turn off. It's not the first time BMW or others have done this.

BMW X3 v. Q5
 

Went to a BMW X3 demo event, where participants could drive BMW X3's and 3 competitors. they showed a longer video with BMW v. Q5, Mercedes GLK 350 and Lexus SUV. Each vehicle was set up on rollers, first with rollers (no traction) on the front wheels, then the rear, then only one rear wheel with traction. BMW immediately had greater traction on every test, and moved off the rollers much quicker. Lexus was the worst, with Audi and Mercedes in the middle.
They had a graph which claimed that BMW was the only vehicle in the test capable of transferring 100% of its power from the front wheels to the back, and vice-versa,as needed for traction. If necessary, the rear differential could transfer most, but not quite all traction to a single rear wheel with traction. I can't recall the exact percentages listed for the other cars, but I do recall that Mercedes could only transfer 70% to the axle with the most traction, and Lexus was limited to a 35% transfer to the rear wheels. Audi was somewhere near Mercedes I am not qualified to interpret this data, but is it disprovable? BMW is running these events nationwide. I'd be surprised if the whole thing is a fraud.

Thanks for posting this video.

I don't drive on rollers.

Haha! That's got to be it. Maybe one of the mods can do a graph over time showing how often new posts on this topic show up. ;)
