Visitors to the 2011 Frankfurt Motor Show got the biggest clue yet as to the look of the production five-door up!, in the shape of the cross up!, one of six small car family concepts that were displayed alongside the three-door city car model. The cross up! previews the five-door up! but with the styling cues of an SUV, including suspension raised by 15 mm all round. The most obvious differences when compared with the standard up! are of course the additional doors and the styling of the C-pillars. While on the three-door car the shoulder line and windows ascend towards the rear near the C-pillars, on the five-door the two elements form a straight line, creating a more upright appearance.
