This engine features a reinforced crankshaft with larger main bearings and new pistons with a lower 9.5:1 compression ratio. This allows the engine to take more boost pressure from a larger turbocharger, which blows compressed air through a reworked intake tract.[12] Revealed in May 2019, this engine is shared with the new MINI Countryman JCW, Clubman JCW[13] and JCW GP models.[14] The engine output increased by 55 kW (74 hp) to 225 kW (302 hp) and torque increased to 450 N⋅m (332 ft⋅lb).
