Since i personally own a CX-9 in AWD trim i can tell you that i have no problem slinging it around, within reason. Obviously you can't be an idiot here and you have to realize that you're not driving a car and that your center of gravity is much higher than in a car. But in the realm of larger CUV's the CX-9 definitely out handles ANY of it's competition IMHO. It feels planted at all times, is stiffly sprung, exhibits a minimum of body roll and lean in corners, and handles extraordinarily well for what it is ( a 4500lb vehicle with a 3.7L NA V6 ), mind you it creates about as much torque as it does HP, and i've almost never found myself wanting for more oomph when passing, even in triple digits.
for reference, here's some interesting reading about the base version of the 3.5L Duratec workhorse Ford engine Mazda modified and placed in the CX-9.

With a large enough wallet, just about any vehicle, no matter how large, can be made to feel and respond more sportily. Look at vehicles like Cayenne S, ML63 AMG, and Supercharged Range Rover, and don't forget to look at their price tags...
But that is not the spirit of the OP's question.
The 2.0T will never equal the V6 competition as far as off the line acceleration goes. Turbo Lag will always be an issue when you've only got 1.
Here are a few pics of it after my latest round of Plasti-Dip fun.
