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 118 hp at 6000 rpm) in 2007–2010 Cooper; N14 (Single VANOS, Turbocharged 171 hp at 5500 rpm) in 2007–2010 Cooper-S; N14 (Single VANOS, Turbocharged 208 hp at 6000 rpm) in 2009–2013 JCW Cooper; N16 (Double VANOS, Valvetronic 121 hp at 6000 rpm) in 2011–2013 Cooper and N18 (Double VANOS, Valvetronic Turbocharged 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.

1.6-litre turbocharged (PSA)

The turbocharged 1.6 L unit adds gasoline direct injection and has special low-pressure die-cast heads. It has an 85.8 mm stroke for a total of 1598 cc of displacement.

At first, there were two versions on offer – the THP150 and THP175, also known as the EP6DT and EP6DTS respectively within Peugeot. The first was later updated as EP6CDT and also as THP163, EP6CDTM.[11] There is also EP6CDT MD – with lowered compression ratio.

For the THP150 maximum torque is 240 Nm at 1400 rpm. Power output is 150 PS at 5500 rpm.

Applications:

For the THP163 maximum torque is 240 Nm at 1400 rpm. Power output is 165 PS at 5500 rpm.

Applications:

For the THP175 (EP6DTS, later EP6CDTS) maximum torque is 247 Nm at 1600 rpm, remaining flat to 5000 rpm. Power output is 175 PS at 5500 rpm. An overboost function is available which temporarily increases torque to 260 Nm between 1700 rpm and 4500 rpm in gears 3 to 5.

Applications:

In 2010 Peugeot released the 1.6 THP engine (EP6CDXD[11]) with 200 PS at 5500 rpm, maximum torque 275 Nm at 1700 rpm. It featured direct injection, twin-scroll turbocharger and Valvetronic variable valve lift. It was first introduced in the Peugeot RCZ sport compact for the 2010 model year, where it generates 204 PS.

Applications:

The 2012–2014 Mini John Cooper Works GP featured additional performance, with 218 PS at 6000 rpm and 280 Nm of torque at 2000–5100 rpm from a larger turbo and engine internals.[13]

PSA has now released a new Euro 6 engine based on the THP in the following Engine codes:

In 2024, Stellantis unveiled the third generation of this engine (EP6LTCHPD) with 150 hp (110 kW) at 5500 rpm and 300 N⋅m at 2000 rpm. This variant is paired with a seven-speed dual-clutch automatic transmission (trade name e-DCS7) with an integrated 92kW electric motor, for a combined total of 195hp and 350 N⋅m.[14][15][16]

Applications:

In 2025, Stellantis unveiled the North American version known internally as the EP6CDTX for use in STLA Medium and STLA Large vehicles in conventional non plugin hybrid setups, for the North American market. It has a power output of 210hp and 230lb torque.
