This could just be testing Roush specific parts or it could just be an older "Jack Roush Edition"/Stage 3 test car.......but Roush do a lot of testing and development for Ford so this could be testing things for S650. Those are certainly some large cables/pipes going from the engine bay into the cabin.

Intersting find. I think the base GT wheels could hint they are not testing some new highend stuff for the S550. Also it got a PEMS (Portable Emission Measurement System) installed (just look at the exhaust)
