Citroen has revealed a frugal version of its new C4 Cactus.
The exterior features a number of aerodynamic changes, which has reduced the drag by 20%. It also runs on low resistance tyres.
Most of the changes are to be found under the skin, where the engineers were able to cut 100kg by using lightweight materials.
The C4 Cactus Airflow 2L is powered by a hybrid air powertrain, which consists of a petrol engine, compressed air storage unit, hydraulic pump, automatic transmission and epicyclic gear train.
Citroen claims that this concept will be able to return a combined fuel consumption figure of 2,0 l/100km.
If these figures prove to be true, it will likely set a new world record for the SUV with the lowest consumption figure in existence.
