BMW now thinks that they make the best RWD and AWD cars in the world?
BMW are trying to make (and actually they have succeed) most dynamic on-road
AWD system ... A system that will pair AWD traction & safety with RWD driving dynamics. They have no ambition to top off-road benchmarks of quattro and other AWD systems. xDrive can still go off-road, but don't expect miracles. But on-road ... there xDrive is one of a helluva good AWD systems.
Of course xDrive is not perfect. Yet. But the Dynamic xDrive ...
Seriously: BMW are very determined to top Audi in AWD area. It's an abitiuos goal, but they have good results already ... Arjeplog winter testing center was only the one move of many in that way. While Audi are targeting BMW's driving dynamics (excellent handling, steering, braking), BMW are taking on Audi's traction & ride stability (AWD system).
I'm eager too see a road test between an Audi vehicle on new modular platform with rear-biased quattro, and a BMW vehicle with Dynamic xDrive. I hope year 2008 will give us some real answers who has done better homework: BMW or Audi.
