Well, here are my thoughts
1. Matte black exterior color option
2. ABL across the dash
3. Less gross weight and/or better fuel economy
4. Integrated Navigation system
Someone else has mentioned this here, but if the Camaro had the option of an extremely fuel-efficient powertrain(something like the Volt), that car would be the only one I would ever want and I would practically keep buying it for the rest of my life.
I believe the exterior design of the fifth gen. Camaro is so overwhelmingly powerful that it has a massive appeal for even the consumers who don't care for performance and would rather pay for efficiency than horsepower. It is pulling in consumers of all categories to the pony car sector as it is and I would think that it has a viable potential for a much broader development and application.
