Overview
- From March 2026, EU‑spec M5s adopt a Miller‑cycle S68 with about 40 hp less from the V8, with the XM Label receiving the same change from April.
- BMW says combined output remains 717 hp for the M5 and 738 hp for the XM Label via electric‑drive software optimization.
- The changes apply across EU countries and in non‑EU markets that follow EU emissions rules, with torque figures not specified.
- Euro 7 compliance measures include revised engine management and upgraded exhaust aftertreatment alongside the new combustion strategy.
- Separately, BMW has abandoned a fixed shutdown date for V8/V12 production, moving assembly to Hams Hall while retaining about 400 Munich workers to make key components.
