About the BMW S68B44A Engine

The BMW S68 is the current-generation M TwinPower Turbo V8 developed by BMW M GmbH for the highest-output M SUV models. In Competition specification — as designated by the S68B44A code — the engine produces 460 kW (625 horsepower) and 750 Nm of torque, giving the X5M Competition a 0–100 km/h time of 3.8 seconds and a performance profile that defines the benchmark for high-performance SUVs.

The S68 is developed and assembled at BMW M GmbH’s facility in Munich — each unit individually built with the same attention to component selection and assembly tolerance that characterises BMW M’s approach to all their bespoke powerplants. The engine features a hot-vee twin-turbo layout, direct injection, Double VANOS variable camshaft timing, Valvetronic variable valve lift, and an 8,000 rpm redline — all within an architecture designed to sustain the kind of sustained high-load use that performance SUV driving demands.

The S68 represents the successor to the long-running S63 engine family — incorporating lessons learned from years of S63 development across multiple generations of M5, M6, X5M, and X6M competition in both road and motorsport contexts. It is built to a higher specification than its predecessor in terms of both outright output and thermal management, reflecting the increasing performance expectations of the BMW M customer base.
