As a result, Citroën is applying its creativity and technology to a new challenge with the C4 Cactus AIRFLOW 2L concept, which will be unveiled at the Paris Motor Show.

A laboratory for new ideas, the C4 Cactus AIRFLOW 2L is packed with advanced technologies that illustrate the ambition and ability of the brand to develop innovative responses to the automotive challenges of the present and the future.

With the C4 Cactus AIRFLOW 2L concept, Citroën delivers breakthrough fuel consumption of 2l/100 km (over 141mpg), using:
  • 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%
The C4 Cactus AIRFLOW 2L project was undertaken as part of the "2l/100 km vehicle" programme set up by the Plateforme de la Filière Automobile industry group in France. The objective is to reduce the impact of vehicle running costs on household expenditure and to reduce the eco-footprint of car travel.

Citroën decided to progress this project using its newest model, the C4 Cactus. With this vehicle, the brand has made a commitment to bring customers more of what really matters today: more design, more comfort and more useful technology, combined with an affordable cost of ownership. More than any other vehicle, the C4 Cactus lends itself to this ambitious exercise - to develop a very low consumption, high-tech concept that is both efficient and attractive.

With its smooth design lines, efficient engines and technologies selected to reduce vehicle weight, the production Citroën C4 Cactus already boasts a range of features designed to reduce fuel consumption.

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.

Variable-geometry components:
  • 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 components:
  • 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 to channel the air along the wheels
  • The spoiler has been lengthened and an air extractor has been 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
The changes can be identified by the colour of the components and by the materials used. The colour orange identifies all the aerodynamic features and underlines the high-tech character of the C4 Cactus AIRFLOW 2L concept.

The changes reflect how styling and design can contribute to vehicle aerodynamics, reducing vehicle drag for an overall improvement of 20% in terms of aerodynamic performance compared with the production model.
