I would consider it an easy choice to pick the heads up display over the greater power/torque and poorer mileage of the turbo. But now the turbo comes with increased towing capacity, and that difference is significant to me.
The good news is, one can have both if willing to pay for it. If I were buying a new car when these came out, and the CX-5 hasn't taken strides in the meantime, I think the CX-50 would be at the top of my list.
But there's nothing wrong with my 2018 CX-5, other than trade-offs I was aware of from the start, so I'm in no hurry. I'd like to see the plug-in hybrid offering of the CX-50, and also the relative size of the CX-70. The CX-9 is too big for me. I think the CX-5 is a good size, and will probably be fine with the larger CX-50.
I also think I'd probably prefer a plug-in hybrid version, so I'd like to see what that offering is going to look like.
I don't intend to take it off-road or do anything more adventurous with it than I'd do with my current CX-5, which is already more capable than I need.
Before buying the CX-5 I was leery that the high center of gravity would mean poorer handling. But I consider the way the vehicle handles to be superb. Now I'm used to the high vantage point. I am concerned that the CX-50's higher ground clearance (that I don't need at all), and lower roofline, will mean a more cramped and carlike interior. I like the high vantage of the CX-5, and unlike many here, I like the seating position and comfort of having the seat cushion high above the floor.
