Here's a quantitative comparison between the RDX, Murano, X-3 and FX-35 specs. Feel free to help me fill in the blanks.

 

Thanks for the info... mind if I post this on another site?

 

The BMW get really good mileage concidering it weights A THOUSAND POUNDS MORE!!! It's amazing how much heavier european cars are compared to a similar size Japanese car.

 

The X3 actually weights 4,023 pounds. It would be nice to add the Mazda CX-7 specs...

From carsdirect.com, here are some numbers for the CX-7 Grand Touring AWD

New RAV4 would be nice to add too I think.

 

Comparison of all RDX competitors IMHO

http://www.carsdirect.com/research/c...,USB60BMS201A0

- Ford Edge is even there
- Nothing is available yet for the Volvo XC 50 or Audi Q5 or '07 CRV

I threw in the Mazda6 Station Wagon for fun (actually I'm considering it - fully loaded it will be 10k below RDX - Would be really nice to have a MazdaSpeed6 Station Wagon )

 

Thanks brassard for catching the X-3 weight - should've noticed a small SUV at over 5,000 lbs doesn't make sense

Comp table has been updated with all of your suggestions including some info on the CX-7

foolioness - feel free to post elsewhere, but brassard's suggested carsdirect site looks even more comprehensive

 

I just test drove a RAV4 and I think you need to add the V6 to the comparison, though feature wise it's probably not on par with the Acura/Infiniti/Beemer.
