BMW Doubles Down on Combustion: The Future of Six-Cylinder and V8 Power

Despite the automotive industry’s rapid shift towards electrification, BMW M is reaffirming its commitment to internal combustion engines (ICE). Recent statements from M CEO Frank van Meel indicate that the iconic inline-six and V8 engines will remain in production as long as demand persists.

Demand Drives the Decision

BMW’s strategy diverges from many automakers setting firm deadlines for phasing out ICE vehicles. Van Meel emphasized BMW’s long-standing tradition with six-cylinder engines, considering them “iconic,” and acknowledges the continued preference for combustion engines among a significant customer base. This is particularly true for those who aren’t yet ready to fully embrace electric vehicles or reside in areas where charging infrastructure is limited.

Future M Models to Retain ICE

The next generation BMW M3 (G84) is slated to feature an updated 3.0-liter engine, potentially incorporating mild-hybrid technology. The upcoming X5 M and X6 M will continue to utilize the larger 4.4-liter V8 unit. The B58 engine will too continue powering M Performance vehicles, including the replacement for the M340i, with the next M350 expected to deliver increased power.

Pro Tip: The enduring popularity of the M340i Touring demonstrates the demand for practical, high-performance vehicles that still offer the visceral experience of a combustion engine.

Navigating Emissions Regulations: A Regional Divide

While BMW M is committed to ICE, navigating increasingly stringent emissions regulations presents challenges. In Europe, the V8 engine powering the M5 is experiencing a horsepower reduction, offset by an increased electric motor output to maintain overall system performance. Similar detuning is occurring with the XM’s engine, again compensated by electric motor enhancements.

However, North American customers will continue to receive the M5 and XM with the full, original engine output, as emissions regulations are less restrictive in the United States.

Mild-Hybrid Technology: A Bridge to the Future

The anticipated mild-hybrid system for the next M3 is likely a direct response to Euro 7 compliance requirements. This technology allows BMW to maintain performance levels while meeting stricter emissions standards. It represents a pragmatic approach to bridging the gap between traditional ICE power and full electrification.

FAQ

Will BMW completely stop making combustion engines?

Not as long as there is sufficient demand. BMW M CEO Frank van Meel has stated they will continue production as long as the market desires them.

Are there differences in engine power between Europe and the US?

Yes. Due to stricter emissions regulations in Europe, the V8 engine in models like the M5 is being detuned, while the US market retains the full power output.

What is mild-hybrid technology?

Mild-hybrid technology provides a small electric boost to the engine, improving fuel efficiency and reducing emissions without the full capabilities of a plug-in hybrid.
