PSA Peugeot Citroën and Bosch Partner on Hybrids

By Kevin Miller


PSA Peugeot Citroën showed the diesel hybrid four-wheel drive Peugeot Prologue and and Citroën Hypnos concepts at the Paris Motor Show. The group has now announced a strategic partnership with Robert Bosch GmbH for bringing the cars to market. Under the terms of the agreement, Bosch will co-develop, industrialize and supply electric motors and power electronics for the showcased powertrain, which is due in Peugeot and Citroën vehicles in 2011.

While PSA Peugeot Citroën typically sources most components from various suppliers, that is not the case for their diesel hybrid program. As part of their partnership, Bosch will be the sole supplier of the rear electric motor, the front-mounted high voltage alternator and the power electronics that will control them. In addition, Bosch will specify the interface between the electric and electronic components, the antilock braking system (ABS) and the electronic stability program (ESP) to enhance energy recovery.

Peugeot Prologue ConceptThe strong collaboration between the partners’ engineering and design teams is intended to shorten each firm’s learning curve about hybrid systems, as neither team has a cache of hybrid systems knowledge large enough to independently support development of this powertrain. Implementing a diesel hybrid technology has been stated as a key focus of PSA Peugeot Citroën’s environmental strategy, though developing and industrializing this technology is a major challenge for the carmaker. The choice of Robert Bosch GmbH as their partner demonstrates the group’s recognition of Bosch’s expertise in vehicle electrical systems. Indeed, Bosch is the world’s leading manufacturer of automobile equipment, and has been chosen to supply and help develop a number of components for this system.

Within the Bosch group, the expertise of roughly 370 associates is pooled in a hybrid project unit, whose purpose is to develop and market systems and components for hybrid and electrical vehicles. With this partnership, PSA Peugeot Citroën has shown a willingness to enter special strategic relationships with certain suppliers over the long term. For Bosch, this close cooperation with PSA Peugeot Citroen offers a promising opportunity to jointly develop an innovative, powerful and competitive hybrid system. Both firms hope that the synergy gained from this agreement will strengthen the European hybrid technology industry.
