I will be ordering in a month, so whichever is for sale then I guess

The will 4.8 deliver daily driving satisfaction. However, consider this thought that kept repeating in my head last week as the DC area temperature hovered near 100 degrees. If only I had ordered the vented seats...I wouldn't have swamp backside everytime I get out of my truck.

That would still be 2008. Go for 4.8.

3.5i is the designation for the X5 with the N54 engine (I6 TT petrol engine in the 535/335/135). I believe the 2009 models will recieve the N54 engine.

The difference in the MPG figures between 3.0i and 4.8i when driving are not that much, the advantage of the 3.0i I believe is when you are stuck in traffic as you burn less petrol.

Doesn't the V8 shut down to 4 cylinders when not in use?

I honestly don't know if it does.

Nope. BMWs don't do that.

:thumbup: thanks.

I'd say the 4.8 for 3K, the 3.0 is nice but it could use more punch for sure! The N54 would be great to have in this truck, but I think the 3.5d is the one to have. 452 lb/ft of torque... sick!!!! That's more than the V-8 M3 and will get better fuel economy. I am looking to get a 335d when they come out then when our X5 3.0L lease is up get the wife an X5 3.5d then brew my own home brew bio-diesel and tell OPEC to F-off!

^It's not exactly hard to have more torque than the M3 :rofl:
