2006 4dr SUV 225-horsepower 3.0L I6
5-speed shiftable automatic AWD		 The 3.0L i6 is rather underpowered, and it's hard for me to squeeze even 22 mpg out of my X5. Most of the time, I get close to 20. Most V8 X5s from this generation get 16-18 mpg. see full BMW X5 review
2004 4dr SUV 225-horsepower 3.0L I6
5-speed shiftable automatic AWD		 I get a consistant 16.6mpg. Mostly in town driving. see full BMW X5 review

5-speed shiftable automatic AWD		 It gets about 16 mpg in town and about 19-20 on the highway. For the amount of performance I should not complain but I would love a SUV that got about 30 see full BMW X5 review

7-speed shiftable automatic AWD		 Have a V8, so I should have expected, but mpg is averaging about 16 around town. With the current gas prices, I dread going to the pump. $90 to fill up the huge tank. see full Mercedes-Benz M-Class review
