M340i

The M340i nameplate was introduced with BMW’s seventh-generation 3 Series sedan, arriving as the first M Performance version of the G20-era sports sedan. It was revealed in late 2018 and reached the market in 2019, depending on region, as the range-topping six-cylinder alternative below the full M3. BMW positioned it as the performance-focused 3 Series for drivers who wanted a sharper chassis, stronger acceleration, and more of the M division’s character without moving to a full M car. Over time, the nameplate has continued on the 3 Series sedan, and it remains part of BMW’s modern performance lineup rather than a discontinued or revived badge. Enthusiasts often see it as the bridge between the core 3 Series trims and the true M models, carrying forward the long BMW tradition of six-cylinder sport sedans in a more accessible package.
