Citroen revealed its project created for the “2l/100 km vehicle” programme set up by the Plateforme de la Filiere Automobile industry group in France. Based on its latest crossover and dubbed the C4 Cactus Airflow 2L Concept, the new vehicle was unveiled at the 2014 Paris Motor Show and is looking better than expected.
The C4 Cactus is already a sexy crossover but in order to make it even more aerodynamic, Citroen added a new front bumper with three air intakes that continuously adjust in accordance with the vehicle use, new mobile side deflectors, wheels fitted with active shutters that are controlled by centrifugal force and 19-inch ultra low rolling resistance tyres.
Moreover, the wheel arches feature an ‘Air Curtain’ that can be activated with small aerodynamic slats on either end of the front bumper. Furthermore, the spoiler was lengthened and a new air extractor was added on the rear bumper in order to reduce air turbulence which can increase the drag coefficient.
The standard door mirrors were replaced by slim rearview cameras. LED light modules found at the front and rear replace the standard lights and not only they save energy but also improve fuel economy.
Compared with the production model, the C4 Cactus Airflow 2L Concept reduces the vehicle drag by 20 percent. In order to improve the fuel consumption, the vehicle is also lighter and comparing with the standard model concept shaves off a further 100 kg.
The difference was obtained thanks to the use of aluminum, high-yield steels and composite materials. Under the hood, we find a Hybrid Air powertrain consisting of a three-cylinder PureTech petrol engine, a compressed air energy storage unit, a hydraulic pump/motor as well as an automatic transmission with an epicyclic gear train.
In addition, an intelligent electronic management system manages input from the driver to optimise energy efficiency. As a result, the fuel consumption of the C4 Cactus Airflow 2L Concept is just 2l/100 km or 141 UK mpg.
