X5 4.4I vs Jeep Commander Hemi
 

So, this guys pull by me at a stop light. Looks at me and asked me, Vanos vs Hemi? before i anwsered I had already deactivate DSC. Neck to neck the first 200 feet and i am still waiting for him to catch up !! He comes up to me at another stop light and asked me is that the new X5 M? i laughed my a... off and told him, you just got beat by a naturally aspirated 2004 4.4I!!! his, 2009 jeep commander with Hemi 5.7L. The look on his face was worth this posting!!! I bet he will look into selling that piece of junk!!

that's cool, man. any mods on your X?

Great, keep up the good work :) Worth the fun.

No mods. Just Stock. Looking at the Dinan exhaust System!!

i love it. but watch out for the hemi's with I/H/E upgrades. they breathe a hell hole of air. At that point we get the x5 50i

But still, for stock 4.4 to jump over 5.7l engine :) sounds good.
However If your'e talking about Realy High performance SUVs For example Supercharged Range Rover
ML63AMG
Cayenne turbo S
SRT8.
then we get our X5 M :)

Realy not sure about SRT8 vs X5 M though.
Still our cars run hot

X5M owns the SRT8.

I have read many reviews about the new Jeep. All of them complained that the motor is "soft". I'll pass on a soft motor!

This SUV does not belong in your list. It is not high performance. The others, however, are quite fast.

Well, not slow either, 500HP for facelifted onces.
