Citroen reveals Hybrid Air Cactus concept

Citroen has unveiled its latest concept model, the C4 Cactus AIRFLOW 2L.

Due to be unveiled at the Paris Motor Show next month, Citroen says that the concept Cactus will deliver some of the most impressive fuel consumption figures yet, managing up to 141mpg.


The C4 Cactus AIRFLOW features an aerodynamically optimised design with up to 20 per cent improvement in airflow.

As well as that, the bodywork is manufactured from lighter parts, shedding 100kg in weight and sits on tall and narrow tyres.

It’s also powered by the same Hybrid Air technology that features in Peugeot’s 2008 Hybrid Air and the recently announced 208 Hybrid Air 2L model.

According to Citroen, this comes as part of a plan by PSA Peugeot Citroen, Citroen and Peugeot’s parent company, to pioneer vehicles with ultra-low eco-footprints.

The Cactus concept’s exterior has been moulded specifically for better airflow, with three air intakes on the front bumper that continuously adjust to regulate airflow.

Aerodynamic side deflectors have also been added to guide air around the vehicle, while the wheels feature shutters that close to avoid creating drag in the spokes.

Further touches include a lengthened spoiler to reduce turbulence, while Citroen has even gone so far as to remove the wing mirrors altogether and replace them with rear view cameras.

Hybrid Air powertrain

The Hybrid Air powertrain allows the C4 Cactus AIRFLOW, like the two Peugeot Hybrid Air models, to be powered by nothing but compressed air alone.

A 1.2-litre three-cylinder PureTech petrol engine is then linked to the hydraulic motor, with the combined output helping to give the C4 Cactus concept a quick speed boost or for better long-range driving.

The hydraulic motor also recuperates energy from waste heat and when the Cactus breaks, meaning that the motor is entirely self-powered and frees the concept from the limitations of existing electric hybrids.

Although the air-powered Cactus is still in the development stage, the production C4 Cactus officially went on sale earlier this month, priced from £12,990.

Standard tech equipment in the new Cactus includes automatic air conditioning, a seven-inch touchscreen infotainment system, plus a reversing camera, cruise control and parking assist.

The engine range includes a choice of Citroen’s latest-generation petrol and diesel engines, with economy figures of up to 91.1mpg and CO2 emissions from just 82g/km.
