I am almost positive I heard in an early video about the concept that two design teams were set with the task of creating a modern interpretation of the camaro drawing upon the C6, a 69 (ZL1 I think), AND the F-22. While it wasn't about making the car LOOK like the aircraft, it was drawing on the design cues of sharp edges and clean lines. While I couldn't find the video I did find an interview with Tom Peters that he mentions it about 1/3 of the way down. (the video had a high walled courtyard where they had the two full sized clay models in it, does anyone else remember it?)
