BMW is preparing for Euro 7 regulations that are due to come into force in the European Union next year. Instead of waiting until the last minute to implement the necessary measures, changes to the M5 are already being made. There’s both good and bad news for the G90 sedan and its more practical wagon sibling, the G99.
The 4.4-liter twin-turbocharged V8 is reduced from 577 hp to 536 hp, a reduction of 41 hp. Even if the “S68” will produce fewer Bavarian ponies, the overall performance of the system will remain unchanged. BMW M adjusts the electric drive software to keep total output at 717 hp.
The updates introduced for the Euro-Spec M5 also apply to markets outside the EU, which follow the same regulations. In these regions, the super sedan and station wagon will switch to a V8 with Miller combustion technology. This setup reduces emissions while improving efficiency, allowing the M5 to meet the stricter Euro 7 standard.
In addition, the M5 for these markets benefit from further optimized engine management and improved exhaust aftertreatment. BMW says there will be no loss in performance compared to current models, but it doesn’t say whether torque has changed from the V8’s 750 Nm (553 lb-ft). In combination with the electric motor, the current plug-in hybrid M5 delivers a total of 1,000 Nm (737 lb-ft).
The transition is scheduled for March 2026, when the XM label will receive similar updates. BMW’s most powerful production vehicle of all time is also being converted to the Miller combustion process. The M division confirms that the SUV retains its total system output of 738 hp, but does not specify torque. To illustrate, the electrified M flagship currently produces 1,000 Nm (737 lb-ft).
The lesser-known XM 50e is not mentioned in the announcement, suggesting that no changes may be required to comply with Euro 7. As a reminder, the entry-level model combines a smaller six-cylinder B58 engine with an electric motor. It is aimed primarily at Europe, but is also sold in other markets, just not North America. Last year, BMW removed the standard V8 model from the G09 range globally, leaving only the 50e and the Label.
