so can someone easily and simply explain the different awd systems in the x5 over the years ? here's my understanding:

1) original x5's: 60% rear and 40% front under normal conditions. Car can apply brakes to any given wheel, but maximum power a single front wheel is 20% and a single rear wheel is 30%.

2) 2004 models: same ratio as above, but now car can also distribute power front to back, so 100% can go to front or rear wheels. braking individuals wheels are the same, so max at one front wheel is 40% and one rear wheel is 60%

3) new 2007 models: same as system introduced in 2004???

4) next generation, 2008? DYNAMIC x-drive: same ratios as above, but then power can be distributed 100% front to rear AND 100% left to right... meaning any one wheel can receive 100% power.

did i get that right???

thanks.
