Citroen C4 Cactus Airflow 2L concept revealed with a fuel economy of over 141mpg

Citroen C4 Cactus AIRFLOW 2L concept is based on the production C4 Cactus with improved aerodynamics and a new powertrain combining a Puretech 82 engine with a Hybrid Air technology, reducing fuel consumption by 30%.

Thanks to lightweight, high-performance materials like carbon fibre, aluminium, high-yield steels, composite materials & translucent polycarbonate, the concept is 100kg lighter than the production Citroen C4 Cactus.

At the front is a new front bumper with three air intakes that automatically open to cool the engine if needed and also close to improve aerodynamics. There is also a larger rear spoiler, slender rearview cameras instead of side mirrors and 19-inch active shutter wheels fitted with ultra-low rolling resistance tyres.

Compared to the production model, the concept is 20% more aerodynamic.

The C4 Cactus AIRFLOW 2L project is part of the “2l/100 km vehicle” programme and while the production C4 Cactus already has a very impressively low fuel economy of 91.1mpg and CO2 emissions from 82g/km, the Airflow 2L concept has a fuel economy of 141.2mpg (2L/100km).

Powered by a 3-cylinder PureTech petrol engine, a compressed air energy storage unit, a hydraulic pump/motor unit and an automatic transmission with an epicyclic gear train, the concept can be driven in purely petrol power, air power or combined power using both the combustion engine and the compressed air.

The C4 Cactus AIRFLOW 2L concept will make its public debut next month at the Paris Motor Show.
