Citroen Cactus Airflow 2L Concept
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.

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
With these advanced technologies combined, the C4 Cactus AIRFLOW 2L delivers breakthrough fuel consumption of just 2L/100 km. It could therefore be possible, in the medium term, for a production vehicle such as C4 Cactus to reach this target.
This very low level of consumption is the result of:
Optimised design with a 20% improvement in aerodynamics
Lower rolling resistance “tall & narrow” tyres
Lighter parts to reduce overall vehicle weight by 100kg
Hybrid Air technology, which cuts fuel consumption by 30%
INNOVATIVE MATERIALS FOR LIGHTER WEIGHT
The production C4 Cactus is already 200kg lighter than the Citroën C4 hatchback, yet the C4 Cactus AIRFLOW 2L concept sheds a further 100kg. This means Citroën’s designers have reduced the weight of the concept by 11% compared with the production vehicle.
To achieve this, the weight of many structural components has been reduced, with the body sub-structure featuring new materials including Aluminium and High-yield steels. These new materials are structural and help to soak up energy in the event of an impact. They also meet the highest standards in terms of mechanical strength.
A BODY STYLE OPTIMISED FOR AERODYNAMIC PERFORMANCE
With the C4 Cactus AIRFLOW 2L concept, Citroën is taking this approach even further.
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
