BMW M5 and XM updated for Euro 7 standards with hybrid tech

BMW has begun adapting its models to meet Euro 7 standards, which come into force in 2027. The new hybrid M5 is among the first affected: its gasoline V8 has been detuned, though total system power remains unchanged.

Reasons for the Detune

The European version sees output of the twin-turbo 4.4 S68 engine drop from 577 to 536 hp. Engineers have switched the unit to a Miller cycle, reducing emissions and improving combustion efficiency. This mechanical power cap is a necessary step driven by the new environmental rules.

Hybrid Compensation

The M5's hybrid system retains its total 717 hp thanks to updated electric motor software. The electric motor smooths out any loss in throttle response and torque, making the gasoline engine's detune imperceptible in real-world driving. While the V8's torque figure isn't yet specified, the hybrid's combined torque stays at 1,000 Nm.

Changes for the XM

From March 2026, a similar update will apply to the BMW XM Label—the brand's most powerful production model. Its eight-cylinder engine will also adopt the Miller cycle, maintaining a combined 738 hp. The XM 50e version won't be altered, as its inline-six already meets Euro 7 requirements.
