I live 8 miles from Mazda/Toyota Manufacturing where the CX-50 is built. I watched a couple choose a CX-5 over the CX-50 that they were comparing. It wasn't availability. It was that the CX-50 is big for compact SUV and provides almost no increase in space from the CX-5 which is more nimble to drive in town. The 3 inches increased width and 6 inches increased length of the CX-50 is almost exclusively external to the passenger/cargo interior. They are different configurations of the same vehicle. Add the loss of the fully independent suspension and the fact that the CX-5 is still made in Japan (people have that preference) and people generally prefer the 5 to the 50. Personally, I like the 50 better, but smh at the beam suspension. Whichever one I could get with a 6 cylinder motor would be the one I would buy. The 340hp turbo inline 6 is why I am waiting to see the CX-70. If I was willing to settle for a 4 Cylinder I would do the CX-50 on the low end or the RDX.The CX50 is still hampered by limited availability. My local dealer has 111 CX-5s and 18 CX-50s for sale. The second most common car at my local dealer is the CX-30 -48 of those. If I look at multiple other dealers, that ratio is similar. People buy what vendors have.
People buying a full size 3-row are interested in people and cargo capacity. Mainly because most of them should be buying a minivan but are too vain. People buying compacts and subcompacts are looking for nimble, easy to maneuver, turn and park. Us midsize crowd are trading off on both ends. Shown is the spreadsheet I did when I started trying to pry my wife out of her 2012 Honda Odyssey about 1.5 years ago.
