Its first use was in the 2023 revised [BMW X7](/source/BMW_X7) as the M60i.[1] A few weeks after its presentation, BMW showed a study of the [XM](/source/BMW_XM) with a more powerful version of the engine.[2][3] In addition, the basic version is also used in [BMW 760i](/source/BMW_7_Series_(G70)),[4] [BMW X5 M60i](/source/BMW_X5_(G05)), and [BMW X6 M60i](/source/BMW_X6).[5] ## Design The S68 has the same piston stroke of 88.3 mm (3.48 in) and displacement as its S63 predecessor, but the compression ratio of 10.5:1 corresponds to the higher compressed predecessor variants.[6] It has one turbocharger per cylinder bank and both turbochargers are placed in the middle of the cylinder banks in a hot-vee design taken from the previous S63 variant; there is only one exhaust manifold. The S68 is the only current production V8 engine offered with a cross-pattern exhaust manifold for improved turbo charger pressure by combining exhaust pulses which comes at an expense of sound alternation, making the sound closer to a 180 degree configuration V8. The engine oil is cooled by an external cooler, and a newly developed oil pump is used for the oil circuit. The engine is now only offered as a 48-volt mild hybrid powerplant [mild hybrid](/source/Mild_hybrid) system, it has a 9 kW (12 hp) electric motor with a torque of 200 N⋅m (150 lbf⋅ft); unlike the previous mild hybrid systems from BMW, this is installed within the transmission.[1] The electric motor is also used for hot starts, while cold starts are performed by a standard 12 volt starter similar to most other engines. The battery required for this has a 90 Ah capacity. The 48-volt battery found in the X7 M60i, XM, and the 760i models has a capacity of 20 Ah.[6][7] The variable camshaft control ([VANOS](/source/VANOS)) is now electrical and no longer hydraulic.[7] The S68 currently meets the [Euro 6d emissions standard](/source/European_emission_standards),[1][6] but should also be able to achieve the stricter Euro 7 standard, which is planned for 2025.[8][7] The electric motor in the S68 has a torque of 200 N⋅m (150 lbf⋅ft).[2][3] Maximum revs are 7200 rpm.[9] ## Applications - 2022– [G70 760i xDrive](/source/BMW_7_Series_(G70)) - 2022– [G09 XM](/source/BMW_XM) - 2023– [G05 X5 M60i](/source/BMW_X5_(G05)) - 2023– [G06 X6 M60i](/source/BMW_X6_(G06)) - 2024– [F95 X5 M Competition](/source/BMW_X5_(G05)) - 2024– [F96 X6 M Competition](/source/BMW_X6_(G06)) - 2023– [G07 X7 M60i](/source/BMW_X7) - 2023– [G07 Alpina XB7](/source/BMW_X7) - 2024– [G90 M5](/source/BMW_M5#G90_M5_(2024)) - 2024– [G99 M5](/source/BMW_M5#G99_M5_(2024)) - 2024– [Range Rover (L460)](/source/Range_Rover_(L460)) - 2024– [Land Rover Range Rover Sport (L461)](/source/Range_Rover_Sport_(L461)#Third_generation_(L461;_2022–present)) - 2024– [Land Rover Range Rover Sport SV](/source/Range_Rover_Sport_(L461)#L461) - 2024– [Land Rover Defender OCTA](/source/Land_Rover_Defender_(L663)#Defender_OCTA) ## See also - [List of BMW engines](/source/List_of_BMW_engines) ## References 1. ^ [***a***](#cite_ref-mulach-2022-04_1-0) [***b***](#cite_ref-mulach-2022-04_1-1) [***c***](#cite_ref-mulach-2022-04_1-2) Jordan Mulach (2022-04-15).
