BMW's current-generation M V8, still relatively new to the used market with limited widely-documented long-term faults so far.
The S68 is BMW's current twin-turbocharged 4.4-litre V8 used in the latest generation of M models, including hybrid-assisted variants.
As with other direct-injection turbo engines, gradual intake carbon accumulation is expected over time.
As a high-output turbo V8, the high-pressure fuel system remains a watch item consistent with earlier M V8s.
The hot-vee turbo layout places cooling components close to heat sources, similar to the N63/S63 family.
Being a newer, more electronically complex engine, occasional software or sensor-related fault codes can appear.
Stay current with software updates and scheduled servicing — proactive monitoring is the best approach for this newer engine.
Full BMW-specific diagnostic scan to identify the exact source of the issue rather than guessing.
Checking known leak points, wear items and service history against the S68's specific weak spots.
Confirming any rattle, misfire, or rough-running symptoms under real driving conditions.
As a newer engine, the S68 doesn't yet have widely-documented faults — routine servicing and fault-code monitoring are the best proactive approach.
The S68 was used in M5 (G90), M8 (F91/F92/F93), X5M/X6M (F95/F96) and XM (G09).
Still building a long-term track record, but shares enough architecture with the N63/S63 family that similar wear items are worth monitoring.
