1) Where the engine is mounted
2) Where the suspension is mounted
3) Where the steering rack is mounted
4) What TYPE of suspension it has (strut versus double wishbone for instance)
This is why Mazda used a totally unique platform for the RX7, because they knew that using a platform shared with one of their sedans would not produce the sportscar driving dynamics they were looking for.

You are referring to cookie cutter stuff like GM does, which most OEMs do not do. Most take an existing platform and modify it enough to get a different animal...but so does GM, but to a much lesser extent.
