Prince is the codename for a family of automobile straight-4 engines developed jointly by BMW and PSA Peugeot Citroën. It is a compact engine family of 1.4–1.6 L in displacement and includes most modern features including gasoline direct injection, turbocharging, BMW VANOS and variable valve timing. The current BMW variants of the Prince engine are known as the N13 / N16 and N18. It replaced the Tritec engine family in the Mini and was first introduced in 2006 for MINI. Later in 2011 also for BMW models F20 116i and 118i. This was the first longitudinal engine mount option for Prince engine. PSA has started to use the Prince family in 2006 to replace their TU family — the Peugeot 207 being the first car to receive it. The engines’ components are produced by PSA at their Douvrin, France, facility, with MINI and BMW engine construction at Hams Hall in Warwickshire, UK. The co-operation was announced on 23 July 2002 with the first engines produced in 2006. The Prince engine project is not related to the Prince Motor Company. In late 2006, an extension of the cooperation between the two groups was announced,〔(Press release ) 〕 promising new four-cylinder engines, without further details. On 29 September 2010, it was announced by BMW that the 1.6Turbo version of the Prince engine would be supplied from 2012 to Saab for use in forthcoming models, primarily the 9-3. However with the closure of SAAB supply never started.
