Diesel hybrids from Peugeot and/or Citroën may soon appear on more than the show floor of the Paris Motor Show. Parent company PSA announced this week that it has partnered with Robert Bosch GmbH to develop diesel hybrid technology with an eye toward production models. PSA's HYmotion4 four-wheel-drive diesel hybrid powertrain was shown in Paris in the Peugeot Prologue and Citroën Hypnos concept cars in October. At the time, Citroën called the HYmotion4 technology "feasible from an industrial standpoint," and the carmaker now says it will bring the diesel hybrid technology to market in Peugeot and Citroën vehicles starting in 2011. Should the Prologue make it to production, the claimed combined mileage of 52.3 mpg (US) and CO2 emissions of just 109 g/km would certainly be welcomed. The big question with a diesel hybrid setup, though, is cost. Just ask VW. Thanks to Throwback for the tip!

PRESS RELEASE:

PSA Peugeot Citroën and Robert Bosch GmbH join forces on hybrid development

PSA Peugeot Citroën and Robert Bosch GmbH have agreed on a strategic partnership for diesel hybrid technology. The recently signed agreement calls for Bosch to co-develop, industrialise and supply electric motors and power electronics for PSA Peugeot Citroën's four-wheel-drive diesel hybrid powertrain.

Unveiled at the Paris Motor Show on the Peugeot Prologue and Citroën Hypnos concept cars, this innovative diesel hybrid technology will equip Peugeot and Citroën vehicles starting in 2011. Diesel hybrid technology is a key focus of PSA Peugeot Citroën's environmental strategy, and developing and industrialising this technology is a major challenge for the carmaker.

By choosing a core partner, PSA Peugeot Citroën is paving the way to rapid market introduction of hybrid diesel vehicles in Europe. Bosch, the world's leading automobile equipment manufacturer, has been chosen to supply a number of components for this system. PSA Peugeot Citroën is usually sourcing its components from different suppliers.

As part of the agreement, Bosch will supply the rear electric motor, the front-mounted high voltage alternator and the power electronics that will control them. In addition, Bosch will deliver to PSA Peugeot Citroën specifications the interface between the electric and electronic components, the antilock braking system (ABS) and the electronic stability programme (ESP) to enhance energy recovery.

This stronger collaboration between the partners' engineering and design teams will optimise the hybrid powertrain's operation while accelerating the acquisition of mutual expertise in this area, which is expected to expand rapidly in the next few years.

With this partnership, PSA Peugeot Citroën has demonstrated its confidence in Bosch, as well as a commitment to forging special strategic relationships with certain suppliers over the long term. The carmaker believes that this is the right approach for quickly and cost effectively bringing to market technological innovations that can significantly lower CO2 emissions. PSA Peugeot Citroën also hopes that this agreement will strengthen the European hybrid technology industry.

For Bosch, this close cooperation with PSA Peugeot Citroën offers a promising opportunity to jointly develop an innovative, powerful and competitive hybrid system. For 30 years, Bosch has had experience with hybrid technologies and has comprehensive expertise in battery, electrical drive, and brake management, as well as in engine management. 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.
