BMW will discontinue diesel engines in the European 3 Series lineup when the next-generation sedan arrives for the 2027 model year. BMW spokespeople confirmed that models including the 320d and M340d will not return, ending one of the nameplate’s most familiar powertrain options in Europe.

The change applies to the new 3 Series, which is scheduled to enter production in the second half of 2026. BMW is currently conducting final testing of the next-generation combustion-powered car ahead of its launch.

Gasoline engines remain part of the lineup

Although the diesel is leaving, BMW is not reducing the 3 Series to a single type of propulsion. The new gasoline-powered 3 Series has debuted in the United States with a turbocharged four-cylinder engine and an inline-six. BMW will continue offering gasoline engines in Europe alongside the brand’s electric and plug-in-hybrid models.

The next-generation 3 Series’ range-topping six-cylinder combustion model will be the M350 xDrive. That replaces the diesel-powered M340d as the performance-focused six-cylinder option for European buyers.

Plug-in hybrid 3 Series is due in 2027

BMW has also confirmed that a plug-in-hybrid version of the next-generation 3 Series will arrive in Europe in 2027. The automaker has previously said the 3 Series family will continue to offer plug-in-hybrid power, but it has not released specific details about the new system.

BMW has not confirmed whether the next-generation plug-in-hybrid 3 Series will be available in the United States. The electric i3 will also remain part of the broader 3 Series family, giving buyers another alternative to gasoline power.

Current 320d remains available for now

European buyers who want a diesel 3 Series still have an opportunity with the current generation. The existing range continues to include diesel models such as the 320d, but that availability will end when the new generation replaces it.

The phaseout also marks the end of the M340d in Europe. BMW’s decision leaves gasoline, plug-in-hybrid and electric powertrains to serve the next 3 Series lineup, reflecting the broader shift away from diesel in the market while preserving multiple propulsion choices.
