A new co-operation between BMW Group and PSA Peugeot Citroen 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, for the MINI Cooper and Cooper S and the Peugeot 207.

The power delivered by the new engine reaches 70 kW (95bhp) at 6000 rpm. The torque varies from 136 Nm to 140 Nm depending on the application. It uses the same state-of-the-art technologies as the 1.6 litre 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 joint development of the engines took place in the BMW Group R&D Centre in Munich with teams of engineers of both groups. The R&D costs are shared by both partners. The engines are claimed to deliver cutting-edge technology resulting in both significantly lower fuel consumption compared to previous petrol engines and higher level driveability for the final customer.
