Exhaust exit location has NOTHING to do with platform. That's like saying that a couple of bolt holes are in the same spot relative to each other on the windshield wipers, so a Cadillac Deville and Ford F150 must be based on the same platform. Think about it for a second: architectural and engineering differences between a hatchback and sedan variant of the same car are more significant than just an exhaust exit location. The exhaust is a bit of metal pipe hanging beneath the car, not a static integral design aspect. I mean, even variants of the same car often have entirely different exhaust routing. Look at the '02-'06 Altima: the rear section of the exhaust as well as the rear bumper were entirely different on the 2.5 vs 3.5 and that's the same exact car.
The fact that they're manufactured at the same plant doesn't mean anything, either. That's not how it works.
Versa and Sentra have select common components (as with cars from any automaker), but their underlying architecture is different.

"Platform" and Chassis are different.The C platform is a unibody architecture that Nissan can adapt to various uses. Every automaker does this. For instance, EVERY SINGLE Infiniti, save the Titan-derived QX56, uses the same FM platform. They are all different cars and have different chassis designations. But they are all derived from the basic 350z unibody design (the newer ones have evolved quite a bit from the Z itself, but still have much in common with each other). The G is still a V chassis, and the M is still a Y chassis. But they're both FM platform cars.
The platform is a reference to actual engineering. The chassis code is simply a shorthand notation for the models themselves, as well as a simple way to specify certain variable aspects (like engine or market variants).
