After creating the first car, the French invented the Hybrid Air technology !

To cope with the challenge of creating an environment-friendly vehicle, PSA Peugeot Citroën is developing an all-new technology combining Gasoline internal combustion engine and compressed air storage. "Hybrid Air" is a key step in the path toward fuel consumption of 118 MPG (2 l/100 km). The major innovation lies in the way the powertrain adapts to driving styles, adjusting independently to one of three modes: Air, Gasoline, Combined.

Journalists really liked this new technology.

What is it exactly?
  • A new type of full hybrid powertrain that uses petrol and compressed air:
    - An innovative combination of tried and tested technologies: a petrol engine, a unit to store energy in the form of compressed air, a hydraulic motor-pump assembly and an automatic transmission working with an epicyclic gear train.
    - The smart control system adapts the operating mode to the driver's commands and optimises energy efficiency in three different modes: ZEV (Zero Emission Vehicle), petrol internal combustion and
  • An offer that fits closely with the Hybrid4 electric hybrid for more powerful vehicles in segments C and D
  • A more competitive total cost of ownership (residual value, cost in use)
  • A worldwide response to the need for energy-efficient vehicles. A technology that is suited to any climate and driving conditions and to any after-sales service network
What are the benefits for users?


  • 69g CO2/km homologated performance, i.e. 81 MPG (2.9 l/100 km) (internal combustion, manual gearbox, benchmark of 104g CO2/km) for a conventional body style, such as the Citroën C3 or Peugeot 208, without any specific adaptations
  • Savings of 45% in city driving, offering a 90% increase in range in comparison with conventional engines

A comfortable and pleasant drive

  • 60% to 80% in ZEV mode in city driving, depending on the traffic
  • An automatic transmission that offers a top-quality, smooth and pleasant drive

No compromise

  • Vehicle space maintained (boot, cabin, modular design)
  • Reliable and robust: an essentially mechanical system, for easier and more economical maintenance
  • Small environmental footprint. Easily recyclable materials

A technology for all customers

  • Affordable
  • Global. Can be industrialised on numerous markets
  • Applicable to every passenger car and LCV segments, and intended for the B (82 bhp internal combustion engines), C (110 bhp internal combustion engines) and LCV segments
Patents & Partners
  • 80 patents filed by PSA Peugeot Citroën
  • Technology developed in partnership with the French State
  • Strategic partners in this technology: Bosch and Faurecia
