Munich – BMW is signaling a shift away from its iconic V12 engines in most of its vehicle lines, with the powerful powerplant increasingly reserved for Rolls-Royce models. This move comes as the automotive industry prepares for the implementation of the Euro 7 emissions standards, prompting manufacturers to reassess their engine portfolios.
While BMW itself will not be returning to V12 engines, the company’s development boss, Joachim Post, indicated that the Euro 7 regulations can be met through optimization of exhaust and catalyst systems, allowing Rolls-Royce to continue offering the 6.6-liter V12. This suggests a longer runway for combustion engines in the ultra-luxury segment than previously anticipated. The decision highlights a divergence in strategy between BMW and its Rolls-Royce subsidiary, with the latter maintaining a commitment to the V12 experience.
Rolls-Royce Remains a V12 Bastion
The BMW N74 engine, a twin-turbocharged 6.6-liter V12, has been a staple in Rolls-Royce vehicles since 2008. According to Wikipedia, it replaced the N73 and marked BMW’s first foray into turbocharged V12 technology. The engine delivers between 400–465 kW (536–624 hp) and 750–900 N⋅m (553–664 lb⋅ft) of torque, providing the signature smooth power delivery expected from the luxury marque.
Post’s comments, given to Autocar, suggest that BMW believes it can navigate the stricter Euro 7 requirements without needing to develop entirely new internal-combustion engines, a costly undertaking. Instead, the focus will be on refining existing technology. This approach allows BMW to continue offering four-, six-, eight-, and 12-cylinder engines, catering to a diverse range of customer preferences.
Euro 7 and the Future of Combustion Engines
The Euro 7 standards, set to be implemented in the coming years, aim to further reduce vehicle emissions, particularly those of particulate matter and nitrogen oxides. BMW Blog reports that BMW believes these standards can be met through exhaust and catalyst optimization, preserving the V12 for Rolls-Royce.
This contrasts with previous statements from Rolls-Royce. In 2023, former CEO Törsten Müller-Ötvos indicated a move towards fully electric vehicles, suggesting the V12’s days were numbered. Even though, the latest developments suggest a more nuanced approach, allowing for a continued offering of combustion engines alongside electric options.
BMW’s Broader Engine Strategy
While the V12 will remain exclusive to Rolls-Royce, BMW continues to invest in a range of engine technologies. The company’s commitment to offering a variety of cylinder configurations demonstrates a desire to cater to different market segments and driving preferences. Autoblog highlights that Rolls-Royce is simultaneously pushing ahead with new electric vehicle development, indicating a dual-path strategy for the brand.
The N74 engine, which powers current Rolls-Royce models, replaced the naturally aspirated N73. Autoevolution notes that the first V12 used by Rolls-Royce in a road-going car was launched in 1936, showcasing the engine’s long and storied history with the brand.
The decision to preserve the V12 for Rolls-Royce underscores the brand’s commitment to delivering an unparalleled luxury experience. The engine’s smooth power delivery and distinctive sound remain highly valued by discerning customers.
Looking ahead, the automotive landscape will continue to evolve as manufacturers navigate the transition to electric mobility. While BMW is embracing electrification across its broader lineup, Rolls-Royce will continue to offer the V12 as a symbol of its heritage and commitment to uncompromising luxury. The future will likely spot a coexistence of combustion and electric powertrains, catering to a diverse range of customer needs and preferences.
