A F16 X6 prototype was spotted in China with minimal camouflage that reveals some of the final design details including larger headlights connected to the kidney grille, shark nose, a pair of air breathers on the sides of the car, and the coupe-like roofline which flows nicely into the trunk. The length of the F16 X6 increased from 4877mm to around 4910mm.
