Prince is the codename for a family of straight-four 16-valve all-aluminium gasoline engines with variable valve lift and variable valve timing developed 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 such as gasoline direct injection and turbocharger.
The BMW versions of the Prince engine are known as the N13 and the Mini versions are N12 (Double VANOS, Valvetronic 88 kW (118 hp) at 6000 rpm) in 2007-2010 Cooper; N14 (Single VANOS, Turbocharged 128 kW (171 hp) at 5500 rpm) in 2007-2010 Cooper-S; N14 (Single VANOS, Turbocharged 155 kW (208 hp) at 6000 rpm) in 2009-2013 JCW Cooper; N16 (Double VANOS, Valvetronic 90 kW (121 hp) at 6000 rpm) in 2011-2013 Cooper and N18 (Double VANOS, Valvetronic Turbocharged 135 kW (181 hp) at 5500 rpm) in 2011-2013 Cooper-S.[1] 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 and F21 114i, 116i and 118i . This was the first longitudinal engine mount option for Prince engine.
PSA started to use the Prince family in 2006 to replace a part of their TU family (the other part being replaced by the EB engine) — the Peugeot 207 being the first car to receive it.
The engine's components are produced by PSA at their Douvrin, France, facility, with MINI and BMW engine assembly at Hams Hall in Warwickshire, UK.[2] 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,[3] promising new four-cylinder engines, without further details.
On 29 September 2010, it was announced by BMW that the turbocharged 1.6-liter version of the Prince engine would be supplied from 2012 to Saab for use in forthcoming models, primarily the 9-3.[4][5] However, with the closure of SAAB, supply never started.
At the Geneva Auto Show 2011, Saab unveiled their last concept vehicle: the Saab PhoeniX was fitted with the 1.6-litre, turbocharged BMW Prince engine with 147 kW (200 PS).[6][7]
On 25 June 2014 1.6-litre turbo Prince engine won its eighth consecutive International Engine of the Year Award in the 1.4 to 1.8-litre category. In 2014 the Prince engine beat, among others, the new BMW B38 engine which is replacing the Prince engine in the Mini and BMW lineups.[8][9]
