PEUGEOT will put the emphasis on low fuel consumption and emissions by showcasing its 208 HYbrid Air 2L model.

The 2L stands for two litres per 100km - equivalent to 141mpg - and is based on a production version of the Peugeot 208 1.2-litre PureTech 82bhp five-seater hatchback.

To achieve such high fuel economy, the French brand and its project partners used technologies previously reserved for competition and luxury models.

Weighing just 860kg - 100kg less than the production car - the concept is a mix of steel, aluminium and composites.

And its engineers chose only materials compatible with existing production facilities and a high manufacturing output.

So carbon composites are used for the body panels, sides, doors and roof, along with the coil springs providing suspension.

The car has also been fine-tuned aerodynamically with a number of improvements to reduce drag, including a lower stance on the road.

The standard powertrain has been replaced by a hybrid drive system featuring a mix of petrol and compressed air.

HYbrid Air technology combines two types of energy to achieve greater efficiency depending on the driving conditions.

Peugeot says the compressed air is used to assist and even replace the petrol engine to enable maximum efficiency during transition phases, such as acceleration and starts.

In Air mode the car runs on compressed air alone, so gives off no CO2 emissions making it ideal for urban driving, while in Petrol mode it is powered only by the 1.2-litre petrol engine.

The Combined mode is designed for transition phases in urban environments, such as standing starts and acceleration.
