Citroen C4 Cactus Airflow 2L Promises 1.67L/100km, No Door Dings

Through a fanatical observance of aerodynamics and the shedding of a further 220 pounds of weight, the Airflow 2L Concept returns over 141 miles per gallon (1,67 L/100km) (in other words, it consumes just two liters of fuel per 100 kilometers, hence the "2L" in the name).

Aerodynamic drag has been reduced by 20 percent thanks to three adjustable intakes in the front fascia, which can open and close automatically based on driving conditions. Side deflectors divert air around the body while active shutters on the 19-inch wheels further cut down on drag even further. The old concept car trope of video cameras in place of traditional wing mirrors is present, ostensibly to further reduce drag, while Citroën has added an air curtain system on the front bumper to manipulate air around the wheels.

The Airflow's floor is carbon fiber, while carbon composites have been used in the roof, tailgate and doors. Aluminum has been extensively employed, both for structural components as well as the hood and engine cradle.

Under that hood sits the brand's latest Hybrid Air powertrain, which boasts a three-cylinder gas engine as well as a compressed air motor. Citroën reports that this new powertrain is responsible for 30 percent of the Airflow's improved fuel economy.

Take a look below for the full press release from Citroen, as well as a hefty gallery of images of the funky, fuel-efficient five-door. We'll have much more on the C4 Cactus Airflow 2L, as well as everything else the French brand is debuting, when we cross The Pond early next month for the 2014 Paris Motor Show.
