There would be a larger difference in size than there will be between the MKuga and the MKX.
Soon Ford will have
Escape, which will be close in size to the Edge, which will be close in size to the Explorer, which will be close in size to the Flex, which will be close in size to the Expedition, which is slightly smaller than the Expedition EL.
The MKT is a large vehicle, and not very SUV looking. I think Lincoln would be better served by offering a three row option of the MKX as well.
