PSA Peugeot Citroen hasn't had the best of luck lately but a new report is indicating their advanced Hybrid Air powertrain is progressing well.

Set to be launched in B-segment vehicles in 2016, the Hybrid Air powertrain uses a petrol engine, compressed air, a hydraulic motor-pump and an automatic transmission with an epicyclic gear train. The system enables cars to operate in three different modes including petrol only, air only and petrol / air combined.

Peugeot has remained relatively quiet about the system but previously stated it could enable the Citroën C3 or Peugeot 208 to average 2.9 L/100km (81.1 mpg US / 97.4 mpg UK) with CO2 emissions of 69 g/km. The company also noted that the cars could operate as a zero emission vehicles - in Air mode - for 60 to 80 percent of the time in city traffic.
