Used Mini Cooper Engines

MINI cars have used several engine families, starting with the Tritec four-cylinder petrol engines from 1999 to 2007. Tritec Motors in Brazil is the one who makes Mini Cooper engines. Later models adopted the Prince engine family, a BMW PSA joint development, featuring all-aluminium 4-cylinder turbo engines. Current MINIs use TwinPower Turbo 3-cylinder 1.5 L and 4-cylinder 2.0 L petrol engines, delivering up to 231 hp in John Cooper Works models. The MINI Cooper C (2024) has a 1.5 L 3-cylinder turbo mini cooper engine with about 156 PS, while the Cooper S uses a 2.0 L 4-cylinder turbo with 204 PS. Some MINI models, like the Countryman Cooper S E, also include plug-in hybrid systems combining a petrol engine and electric motor for about 221 hp.

Compatibility

Mini Cooper engines, known for their reliability and durability, are not only present in its own vehicles but also in other makes. Similarly, Mini Coopers also employ engines of other makes too. The Prince engine family of 1.4 L and 1.6 L inline-4 petrol engines was jointly developed by PSA Peugeot Citroën and BMW, and it was used in multiple vehicles, including Mini Cooper, Mini Cooper S, Peugeot, and Citroën cars. The Mini versions of Prince engines carry specific BMW engine codes such as N12B16A (1.6 L Cooper), N14B16A/C (turbo Cooper S/JCW), N16B16A, and N18B16A/C in later R56 generation MINIs.

Transmission codes

The GA6F21WA transmission is a 6-speed automatic gearbox from Aisin AW that's been used on many MINI Cooper, Mini Clubman, Mini ONE, and Countryman over the years and with different-sized MINI Cooper engines. If you look at some of the older MINI models such as the Cooper, Mini, ONE and Cooper S, you'll find a lot have gearbox codes starting with GS like GS552BG, GS653BG, GS655BG, GS658BG and GS659DG - and these are tied in with different year and MINI Cooper engine size combinations within the MINI range. You'll come across the GA8F22AW transmission code on Mini Countryman variants with bigger engines (think around 1.499cc and 1.998cc), and you'll find this same code being used on some BMW models too, which suggests they share a certain level of cross-compatibility with other BMW vehicles, not strictly MINI models.

The early days of MINI autos saw the use of electronically controlled CVT units - like the GACVT16Z - on older Cooper/Cooper S/ONE models ( we're talking 2002-2005 here), and these were pretty distinct from the 6-speed automatics that were brought in later. Then there are the transmission codes like GETRAG that appear in MINI models, and you'll also spot these same codes on BMW 1 Series and BMW 3 Series cars, which suggests that at some point or another, some manual and automatic gearboxes were shared between the MINI range and other BMW-branded vehicles.
