The BMW Group – PSA Peugeot Citroën Cooperation on small petrol engines adds on a 1.4 l petrol atmospheric engine
 

The cooperation between BMW Group and PSA Peugeot Citroën has given birth to a new, 1.4 litre petrol engine. This new engine is directly derived from the existing 1.6 litre engine already launched within the car ranges of both partners, namely the MINI Cooper and Cooper S as well as on the Peugeot 207.
The power delivered by the new engine reaches 70 kW (95 ch) at 6000 rpm. The torque varies from 136 Nm to 140 Nm depending on the application. It encompasses the same state-of-the-art technologies as the 1.6 l versions to optimise the output, whilst decreasing fuel consumption: intake and exhaust variable valve timing and variable valve lift. The new engine has the same bore, but a reduced stroke.

The cooperation between the two groups had been announced in Munich in December 2004. The joint development of the engines took place in the BMW Group R&D Centre in Munich with teams of engineers of both groups, R&D costs are shared by both partners. The engines deliver cutting-edge technology resulting in both significantly lower fuel consumption compared to previous petrol engines and higher level driveability for the final customer.

At full charge, the production of this engine family (1.4l +1.6l) will reach one million units per year. The machining of all the components is manufactured for both groups within the PSA Peugeot Citroën plant of Douvrin (region Nord Pas de Calais) also in charge of the assembly for PSA Peugeot Citroën needs whereas the engines for MINI are assembled in the BMW plant in Hams Hall (UK). Production planning encompasses a breakdown of 40% for each of the 1.4 l and the 1.6 l atmospheric engines and 20% of the volume will be for the 1.6 l turbo direct injection engine.
