Comparison Review

Comfort
Passengers in the backseat will be able to stretch out a lot more in the Mazda CX-9 than in the Acura RDX, due to its greater head- and legroom. The Acura RDX offers just a little more front head- and legroom than the Mazda CX-9, making it a little more comfortable for the driver and front passenger.

Convenience
The Mazda CX-9 requires fewer stops at the gas station than the Acura RDX, making it more convenient to drive.

Cost
There are a lot of factors to consider when calculating the overall cost of a vehicle. The main consideration is Manufacturer's Suggested Retail Price (MSRP). The Acura RDX is somewhat more expensive than the Mazda CX-9. Another consideration is the Destination Charge, which is a standard charge for transporting the vehicle to the dealer from where it's built. The Acura RDX carries a much lower Destination Charge than the Mazda CX-9.

Dimensions
Since the Acura RDX is much slimmer than the Mazda CX-9, it'll be much easier to find a wide enough space in a crowded parking lot. If you go with the Acura RDX, you'll have a much easier time finding a large enough space to park than you will with the Mazda CX-9.

Handling
The Acura RDX has the same turning radius as the Mazda CX-9, so they both maneuver the same in and out of tight spots.

Performance
In terms of towing capacity, the Mazda CX-9 is clearly the choice over the Acura RDX for pulling heavy loads. The Acura RDX has a little more horsepower than the Mazda CX-9.

Powertrain
With its lower torque engine, the Acura RDX doesn't do as good a job transmitting power to its wheels as the Mazda CX-9.

Utility
The Acura RDX has less seating than the Mazda CX-9, making the Mazda CX-9 the better choice, if you need to chauffeur many passengers. The Acura RDX has significantly less cargo capacity than the Mazda CX-9.

Warranty
You'll have greater peace of mind with the more generous basic warranty of the Acura RDX than that of the Mazda CX-9.
