If you look at Kubang and current Ghibli images alongside each other, you can see some of the lines from the Kubang feature quite strongly in the Ghibli, eg rear wheel arch, front grill shape, bonnet lines. So I'm expecting to see something quite similar to the Kubang concept updated to reflect the current design language of the Ghibli and QP. For me, that could make for quite a good looking SUV. As others have said, I doubt the body will look much like the mule as this is clearly just a Ghibli body shell with a few aero mods for testing purposes.
Am I offended by the idea of a Maserati SUV? No, not if it secures the viability and profitability of the brand and its future sports and GT cars. The Cayenne and now Macan have been fundamental to this for Porsche.
Would I buy one? If it is any good, quite possibly as a daily driver as I enjoy SUVs having had a number of X5s and RRs over the years, but not as a replacement for a sports or GT Maserati.
The priority here surely is for Maserati to continue to be viable and profitable and to be in a position to develop the quality replacement sports and GT cars that we all want.
