My brother bought some cheap winters for his MS3. The first time I drove it, I noticed a huge difference vs all my other cars. We drove side by side in my AWD CX7, and he beats me everytime from a stop, and stops much quicker than I do. Different cars, different tires yes, but in winters, I beleive!!
If the MS3 was shod in A/S as opposed to summer tires, there's no reason why a much heavier car like the CX7 will out accelerate the MS3 since both cars have the same/similar HP and torque.
As far as stopping goes, I'm sure the MS3 brakes is as good or better than the CX7 since it is a sporty hatchback afterall. Being lighter, assuming the same brakes, it'll stop quick quicker also.
Now, do the same comparison with snow tires on the MS3, the results will be compounded further. No surprise the MS3 with snow out accelerates and stop faster than the CX-7.
Btw, to the topic at hand, if the similarly equipped MDX is within a few thousand as the CX-9, I would probably picked the MDX instead.
I have a loaded 08 GT minus the tow and entertainment package which I purchased for a little less than $32k (before TTL). If the MDX w/ tech package was $33k, I would have chosen than instead.
I had an 08 MDX for an extended weekend at one time and didn't quite like the "feel" of driving it and thought the ride wasn't as plush. Normally that's a good thing but this was going to be the family car.
When I sat in the CX-9, it feels much better driving it, but the ride is very jarring. Even more so than the MDX. I knew it before buying, but can't justify spending like $6k more for the MDX. Hopefully with new tires in the future and having a toddler (from an infant now), we won't mind too much.
