The Car Connection is reporting today something that we've been hearing rumored for a while.
The CX-7 is not built on the same platform as Ford's Edge and Lincoln's MKX.
According to Jay Amestoy - via thecarconnection.com - the CX-7 is on a 'platform unique to Mazda' with a front structure based on the Mazda6/Mazdaspeed6 but the main structure from there back is based on the Mazda5 micro-van, which is itself based on the structure of the Mazda3.
Kind of confusing, but logical given the sportier mission of the CX-7.
