Citroen introduced a facelifted version for its smallest vehicle in the lineup, the C1. Starting with January 2009, Europe switched to the Euro 5 emission standards, and the carmakers had to comply with the new regulations. The French carmaker introduced the C1 precisely in January 2009, with improved engines and different styling. The C1 was available in a five- or three-door configuration, but most of their parts were similar. At the front, the facelifted version sported bigger, tear-shaped headlights. The new bumper incorporated a different, mouth-like grille, crossed by a horizontal bar for the license plate. From its sides, the five-door version featured body-colored door handles. The carmaker tried to upgrade the interior with better materials. There was no instrument cluster apart from the steering-column mounted speedometer. Citroen offered, as an option, an additional dial for the tachometer mounted on top of the speedometer. It was an original, yet unusual, arrangement. In the back, the rear doors sported pop-out, front-hinged windows for the rear passengers. Like its non-facelifted version, the C1 featured a split-folding rear bench, good for two passengers. Under the hood, Citroen and Toyota developed a new engine management unit that lowered the emissions to fit into the Euro 5 levels. The carmaker offered the vehicle with a manual or a 5-speed automated gearbox. It even offers the car a 1.4-diesel.
