Citroen has released the first teaser shot of their new C4 Aircross as well as the first official images a week before its scheduled debut next Friday. The car is expected to be an upgraded, tougher version of the C3 Aircross. The C3 Aircross was a big four-door SUV, so we are assuming the C4 will be a variant that rides higher, has revised styling and raised wheel arches. We expect the same engines to carry over form the previous model, such as the 1.6-liter gasoline and 2.0-liter 150 motors.
