Citroën C4 Cactus Airflow 2L. Gallery Citroen C4 Cactus Airflow 2L concept The Citroen C4 Cactus AIRFLOW 2L concept is to be unveiled at the Paris Motor Show. It is said to achieve fuel economy of over 141 mpg (2l/100km). The innovative combination of creativity and technology A laboratory for new ideas, the C4 Cactus AIRFLOW 2L is packed with advanced technologies that illustrate the ambition and ability of Citroën to develop innovative responses to the automotive challenges of the present and the future. The Citroën C4 Cactus AIRFLOW 2L Concept On the C4 Cactus AIRFLOW 2L, some styling features have been modified and others created in order to optimise vehicle aerodynamics. These can be categorised into two types: Variable-geometry components and Fixed-geometry components. VARIABLE-GEOMETRY STYLING COMPONENTS The C4 Cactus AIRFLOW 2L concept Variable-geometry components include: The new front bumper features three air intakes that continuously adjust in accordance with vehicle use, both for engine cooling and to regulate air flow Mobile side deflectors have been added to effectively guide the air flow around the vehicle The wheels feature mobile shutters activated and controlled by centrifugal force FIXED-GEOMETRY STYLING COMPONENTS The C4 Cactus AIRFLOW 2L concept Fixed-geometry components include: New generation 19-inch "ultra ultra" low rolling resistance "tall & narrow" tyres. Their design improves both energy efficiency and aerodynamics. The large diameter also means they are better able to soak up bumps and dips in the road surface The wheel arches feature an “Air Curtain”. This is achieved with small aerodynamic slats on either end of the front bumper which channel the airflow along the wheels The spoiler has been lengthened and an air extractor added on the rear bumper in order to reduce the turbulence that can increase drag The conventional door mirrors have been replaced by smaller, slimmer rearview cameras to reduce the impact on air flow The vehicle sub-structure has been entirely streamlined so the air flows smoothly underneath the car LED light modules at the front and rear replace the existing lights. Consuming little power, these new modules save energy and benefit fuel economy HYBRID AIR TECHNOLOGY With the latest-generation Euro 6 engines, the production C4 Cactus already ranks among the best in its segment with CO2 emissions from 82g/km and fuel consumption starting at just 91.1 mpg. The C4 Cactus AIRFLOW 2L concept goes even further by adopting the Hybrid Air drivetrain. Presented by the PSA Peugeot Citroën Group in January 2013, and featured on a Citroën C3 at the 2013 Geneva Motor Show, this technology combines a range of proven sub-systems and technologies. Three operating modes are available: Air power (zero emissions) where the compressed air motor takes over from the petrol engine Petrol power, using only the combustion engine Combined power, drawing upon both the combustion engine and the compressed air *source: http://www.citroen.co.uk/about-citroen/concept-cars/c4-cactus-airflow-2l C4 Cactus AIRFLOW 2L | Concept Cars | Citroën UK - Citroën United Kingdom With the C4 Cactus AIRFLOW 2L concept, Citroën delivers breakthrough fuel consumption of 2L/100 km. ...
