BMW S68

The S68 has the same piston stroke of {{cvt|88.3|mm|abbr=on}} and displacement as its N63 predecessor, but the compression ratio of 10.5:1 corresponds to the higher compressed predecessor variants.{{cite web |url=https://www.press.bmwgroup.com/deutschland/article/attachment/T0378353DE/555258 |title=Der neue BMW X7. Seite 3 |work=press.bmwgroup.com |date= |accessdate=2022-06-28|format=PDF}} 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 system, it has a {{cvt|9|kW|abbr=on}} electric motor with a torque of {{cvt|200|Nm|abbr=on}}; unlike the previous mild hybrid systems from BMW, this is installed within the transmission. 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 batttery 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.{{cite web|author=Jeff M |url=https://www.technicalripon.com/bmw-s68-twin-turbo-v8-an-m-division-engine-for-the-masses/ |title=BMW S68 Twin-Turbo V8 - An M-Division engine for the masses |work=technicalripon.com | language=en |date=2022-04-15 |accessdate=2022-06-28}} The variable camshaft control (VANOS) is now electrical and no longer hydraulic.
