2012 BMW X5 M SUV 4dr SUV AWD (4.4L 8cyl Turbo 6A)
Run's like a scalded monkey!
 Admitedly, I've only had it for 1 week after trading in my '08 4.8i last weekend.Drove a 5.0i right before the M, left with the M.First impression is that it is fast; really, really fast compared to the 4.8i. The power is immediate and endless when you dip into the throttle. Steering is quite different from the non M.It's lighter at low speed, tighter at higher speed, wonderful all around.Suspension is tight when it needs to, very compliant over bumps too.Overall, a massive upgrade from my prior X5 and absolutely awesome!!
