400 bhp is about right....it will be nowhere near 500 bhp. The M3 is the wrong comparison.

M3 engine is a much higher state of tune than the V8 TT that will go in the X5. It's a completely different engine and has very different characteristics it's tuned to produce high horsepower at high revs to the detriment of torque which is not what you want in the X5.

A good comparison would be the 335i and the 330i....the twin turbo engine there only produces 30bhp more. It does however produce 400 nm of torque at 1300 rpm versuse 320 nm at 2750 rpm which is a huge difference.
