The red badges, possible red pin stripes and red calipers will let you know. They didn't show these things at the show because they wanted all three vehicles to look similar.
I don't see how it is missing anything... This car looks crazy good! Can't wait to see its capabilities on the street and on the track. Aerodynamics on this car are going to be insane.
Ford doesn't announce lap times for a lot of reasons, but the main thing is all of the prep that goes into the cars and the changing track conditions. You almost never get the same run back to back.
Have fun changing cams and heads on your 392 and or LS or LT engines, I love how Ford heads flow great from the factory, which is also why these engines love boost.
