1)In the A2 the car is supported by the springs and shocks.
Their Aerodyne facility has electromechanical rams.
He said when you test a car, you wantbcc the car "stiff"; since even minor variations in ride height can have a huge difference.
I got the impression that the car suspension is not test locked and free at the A2.
2) "Not as much as you would think " was Gary's response on the engine aero effect.
He stated that the engine effect is minimal compared to the effect caused by cooling flow.
And the exhaust is "lazy, and doesn't shoot out like a rocket out the back "
