BMW Group and PSA Peugeot Citroën have agreed to extend their cooperation in the field of gasoline-fueled four-cylinder engines.
In 2002, PSA Peugeot Citroën and BMW Group agreed jointly to develop and produce a family of 1.6-liter turbocharged gasoline engines, encompassing two technologies: fully variable valve drive and direct injection, with power ratings from 55 kW (75 hp) to 128 kW (175 hp). These engines appear in the newly launched MINI as well as Peugeot and Citroën vehicles.
Other features in the jointly-developed 1.6-liter engines include:
- Fully controlled, on-demand oil pump that requires up to 1.25 kW less drive energy and reduces fuel consumption by up to 1%.
- Single belt drive for all ancillary components.
- Cylinder heads produced by lost foam casting.
- Twin-Scroll turbocharger to improve response time and driving comfort.
- Self-disengaging water pump to reduce fuel consumption and emissions.
The two companies now will jointly conduct a feasibility study concerning a new family of engines, with advanced technology features aimed at delivering excellent power and torque characteristics combined with reduced fuel consumption and CO2-emissions.
If the study confirms the expected technological, industrial and financial benefits the two companies intend to enter into a joint development project.
