The European Union's most stringent emissions regulations yet, known as 'Euro 7,' are set to roll out towards the end of 2026, prompting automakers to adjust their powertrain configurations. BMW is among those affected, with reports suggesting that the M5 will lose some horsepower from its V-8 engine starting this April.
4-liter V-8 will adopt a new Miller combustion cycle, revised engine tuning and electronics, and a more effective exhaust system to meet Euro 7 standards. Output is expected to fall below the current 577 hp rating for the V-8, possibly down to around 535 hp.
To retain the original performance, BMW has cranked up the electric motor. The adjustment will impact all EU-market models, as well as those slated for any market to abide by Euro emissions regulations.
This change is not unique to the M5, with the XM Label also undergoing similar adjustments. American fans of the M5 may recall previous de-buffing of their home market spec, but this change is a new development in Europe.
As the automotive industry adapts to these stricter regulations, it's essential to consider the implications on performance and character. With Euro 7 taking hold, automakers must balance emissions reduction with driving excitement, a delicate balancing act that will be put to the test with the M5's updated powertrain configuration.
The shift towards more stringent emissions regulations in Europe is forcing manufacturers to rethink their approach to performance and efficiency. While it's disappointing for enthusiasts like those who follow the BMW M5, this change reflects a broader industry trend towards reducing environmental impact without sacrificing driving excitement.
