The 35d is slower than the 4.8 at those high speeds. Something you can feel.

But off the line and at lower speeds, the 35d feels like the 4.8 (if not smoother).

I'm assuming the $1800 tax credit only applies for purchase and not for a lease?

I have the Evolve remap which takes the 35d to 345bhp/730Nm torque. I would now assume it will be as quick or quicker than the 48i

Overtaking on the motorway in 6th gear is fantastic!!

Has anyone actualy with sd or with 35d (us version) with ECU mod raced any 4.8i ??? I am very curious to see the result... I have the ECU mod from Hartge 335HP and I have the feeling that I am faster than any 4.8i although i cannot proove it.... because I never raced one.... yet
A guy I know has a 4.8 and doesnt want to race me but when ever i am inside his car and he speeds it feels slower... the only things is far better is the V8 sound....

[330cdsport]

Yep - unfortunately no remaped diesel will ever get that V8 growl

The 35d X5 does sound better than my 335d coupe though.

I test drove the 335d and posted my experience in the Premier Members forum. The bi-turbo diesel essentially irons out any elevation changes. It makes roads flat, and when you have to merge onto the freeway, the acceleration is deceptively smooth. One downshift, about 3k revs, and I was shooting over 130km/h.

GPSnV1:
Off the line, the 35d beats the 4.8 - up to about 50MPH. After that, the 4.8 will perform like any other gasoline engine and move faster than a diesel since the max torque on a diesel is at lower RPMs and, conversely, at higher RPMs for a gasoline engine.
Personally, the "fun factor" and "useful range" is at lower speeds (i.e. up to 50MHP), so the slower acceleration at higher speeds doesn't bother me.

Mine has a check engine light on right now. Going to the dealer this afternoon to find out what's causing the problem...

Huk, I don't know if you are driving a diesel but I am not sure i will completely agree with what you are saying... Don't take me wrong and I am only saying this from experience.... at least my car(sd) rocks up to 200km and not 90 km as you are saying.... and when the second turbo kicks in you don't feel any kind of lag at all at higher rpm....

Now I am thinking that maybe the gasoline will not move faster at higher rpm as you are saying.... why ? lets try to make a more fair comparison x5 3.0si (gasoline) and x5 3.0sd (diesel) both cars are almost the same hp (10hp difference). But there is nothing to compare at lower or higher rpm... with those 2 cars... even if gasoline is faster at higher rpm the diesel will kick its ......

The diesel pulls very strongly right up to as fast as you'd want to go. It certainly does NOT wimp out past 130km/h.
