The tightening of environmental regulations in Europe is forcing car manufacturers to find ways to preserve powerful internal combustion engines. BMW is confident that inline six-cylinder and eight-cylinder engines will remain part of the sports model lineup for a long time, so the company has already prepared them for Euro 7 standards.

The German manufacturer has modernized two key BMW M division engines – the 3.0-liter inline S58 with two turbochargers and the 4.4-liter V8 S68 with twin-turbocharging. Thanks to these updates, these power units will be able to meet new environmental requirements and are expected to remain in production until the 2030s.

During the recent Goodwood Festival of Speed, BMW M division head Frank van Meel confirmed that the company does not intend to abandon six- and eight-cylinder engines. According to him, engineers continue to improve them, increasing efficiency and reducing harmful emissions.

The S58 engine received the most significant changes. It is equipped with a new M Ignite system, which uses a pre-combustion chamber integrated into the cylinder head. In addition, the engine received an increased compression ratio and variable geometry turbochargers. These solutions improve fuel efficiency, especially during active driving.

The updated S58 is already used in modern BMW M3 and BMW M4, and in August 2026, it will also be installed in the BMW M2.

The flagship S68 V8 engine is developing along a different path. Instead of M Ignite technology, it received the Miller cycle, which increases combustion efficiency. Engineers also modernized the engine management system and improved the exhaust gas aftertreatment system, which further reduces emissions.
