2011 BMW X5 xDrive35i 4dr SUV AWD (3.0L 6cyl Turbo 8A)
Just took delivery of my 7th X5 after trading a 2009 35d for a 2011 35d. I loved the 2009 diesel, but road, exhaust, and engine noise were a little too intrusive. BMW refined the 2011 to reduce the "bad" noises while keeping "good" noise like the sporty grumble during acceleration. The suspension also seems to have been improved. It's subtle and the X5 is certainly not Lexus quiet, but I immediately noticed the difference: a more refined luxury feel. Press releases talk about new styling and engines, but not the improved suspension and noise reduction. That's a shame because those improvements address the only significant flaw in my previous X5. Good job BMW, you were listening.
This latest iDrive is excellent. Love the Google search features and 3D city maps. The diesel engine pulls hard and performs well. Highway range is around 640 miles per tank. The only thing I miss from the V8 are the twice weekly visits to the gas pump.
The 8 speed transmission should have been paired with this diesel engine in the 2011 model. The extra top gear would improve highway mpg. It's time to ditch this current stereo system for a more modern/competitive system. Even the upgraded digital surround system isn't all that great.
