3.0si vs 4.8i

[xdrive]

For those who have driven both the 3.0si and 4.8i, could you please share some comments on the driving behaviour of the vehicle between these two engines? Is the 4.8i more fun to drive with than the 3.0si? No doubt the 4.8i will give you a lot more muscles, but howabout handling? Are they more or less the same?

Btw, is the 3.0 bi-turbo going to be available for the 2008 X5? It would be great if is true.

i have 3.0, but never drove 4.8..just finished first long 200-300 miles of weekend trip withe X. i got this truck for the wife knowing she wont need the V8.
the 3.0 seems to have plenty of pep for daily use. she revs up a bit noisily in low speed accel, but very sharp in the 60-90mph range. keep it in sport or full manual.
i 've had a few other hi end v8 cars (a8, s8, e500) and have found that i dont use the manual mode at all with the bigger engines, fwiw..
cant speak for any handling issues. try em both.

Yes, it should be. before 2009.

The difference in power, especially low rpm grunt, is substantial. But this isn't a decision someone can make for you--as others have said you should drive them both. The six isn't weak, so it could well be the best choice for you.
