Here is the current Aerio interior...definatly looks like this will be the next gen since the interior seems unchanged:
Platform should be same anyways as the 02 Aerio was first car built on it. From the looks of the front...looks like it caries the new Suzuki look like that on the Grand Vitara...
Might get interesting as it's going back to a 2.0.....perhaps a Supercharged varient like that on the Concept Aerio that debut in 2000 auto show or maybe a Turbo?
