I was hesitant on AWD. I always preferred FWD due to lower cost and better economy.
But I have changed my tune. I now prefer Mazda's current iteration of AWD. There is very little hit to economy if any at all since they moved to 100% FWD during constant speed cruising, and the handling improvements are real.
Sounds like a practical perspective. I also like that FWD is considerably lighter, though, having a driveshaft that's relatively distributed towards the rear of the vehicle does help with weight distribution.
The turbo 2.5 makes such a generous wallop of torque - you sort of end up needing the AWD system. When I was messing around with the CX-5 turbo demo, I was amazed and not at all expecting the system to shove power to the rear the way it did - high throttle cornering from low speed. It oversteered with a level of precision and response I never thought to be realistic for such a heavy vehicle. However, for normal driving, I can't justify the extra weight.
Then there is the argument of wet traction. While a FWD car is not balanced like a RWD car, it is perfectly fine with good tires and an LSD. Open diffs are crap. Take a look at what Honda/Acura has been achieving on a FWD chassis for decades.
Lower trim CX-5's with the NA engine, 17" wheels and FWD address the biggest gripes I had after testing the signature turbo - but then again, like I mentioned in my review, my preferences and requirements in a vehicle are drastically different from the average consumer, and I unfortunately I don't think the NA will offer quite enough grunt for even a lighter base model CX-5 on 87 octane.
Concerning my 3200LB Mazda 6 with the 91 octane tuned NA and 17" wheels, these things just aren't an issue like they are on the CX-5 I tested. - Back to the topic of FWD vs. AWD. The only problem I have experienced in starting off in snow, and that's because of the open differential, not the fact that there is no power being sent to the rear. In another life, I drove a 1995 Nissan Maxima SE with the very rare 5 speed manual and LSD stock from the factory. That thing put down V6 torque to the front wheels unimaginably well.
