PSA Peugeot Citroen Hybrid

PSA Peugeot Citroen Hybrid HDi technology comprises of a 1.6-litre HDi diesel engine, a particulate filter system (DPFS) with the latest generation Stop & Start system, an electric motor, inverter, high-voltage battery pack and dedicated control electronics. The cars are also equipped with an electronically-managed manual gearbox.

The Stop & Start system enables the Hybrid HDi vehicles to start and drive using only the HDi diesel engine, even when the high-voltage battery pack is totally flat. Other hybrid vehicles, in contrast, would be totally immobilized in this situation.

The Hybrid HDi introduces several innovative features:
• Recovery of kinetic energy during deceleration and braking.
• All-electric mode, or Zero Emission Vehicle (ZEV), eliminating noise and emissions for urban driving at up to 50 kilometers an hour.
• Extended ZEV mode, in which electrical power is used by default, depending on the battery charge level.

For main road and motorway driving, the electric motor can provide a 35% power boost for extra acceleration when needed, thereby enhancing driving comfort.

PSA Peugeot Citroen could market its Hybrid HDi vehicles as early as 2010. However, their introduction rests on making this technology available at an affordable price. Today, the price gap between a Hybrid HDi model and a comparable diesel HDi model is still too wide and would have to be halved to make diesel hybrid vehicles accessible to most consumers.

PSA Peugeot Citroen is committed to meeting the challenge of lowering the cost of this technology. Only by meeting this goal will the Group be able to ensure the widespread distribution of the innovative Hybrid HDi solution so making a significant contribution to protecting the environment.

PSA Peugeot Citroen has asked the French Agency for Industrial Innovation to support the project.

Enhancing fuel efficiency and reducing CO2 emissions to address the issue of greenhouse gases is a critical component of PSA Peugeot Citroen product strategy. PSA Peugeot Citroen vehicles rank amongst the best in class worldwide for low fuel consumption and C02 emissions.

To sustain this achievement, PSA Peugeot Citroen is leveraging its expertise in high-tech diesel engines, a segment where it is a world leader (more than 8 million cars with the common-rail HDi engine sold), and its pioneering role in electric vehicles. The new Hybrid HDi system presented today combines many advantages of the HDi diesel engine with those of an electric motor for urban driving.
