The manual transmission is dead across the entire 3 Series lineup. That’s the quiet bombshell buried inside BMW’s plan to replace the M340i with the new G50 M350, a car that otherwise reads like good news for anyone who treats their sedan like a driver’s tool rather than a status symbol.
The M350 drops the “i” suffix — that letter now belongs exclusively to EVs — and picks up a revised B58 inline-six with mild-hybrid assist producing an estimated 410 to 417 horsepower. That’s roughly 30 hp more than the current North American M340i and nearly 50 more than the detuned European version. The gap between this car and a proper M3 has never been this narrow.
And here’s the kicker: there won’t be an M3 to compare it to for a long time.
The full G84 M3 isn’t expected until July 2028 at the earliest. The M350 enters production at BMW’s Dingolfing plant in November 2026. That leaves roughly two years where this is the sharpest 3 Series money can buy on the new platform.
BMW didn’t plan it as a strategy, but it functions as one. Every buyer who would have cross-shopped an M3 now lands squarely in M350 territory.
The car rides on CLAR II, an evolution of the existing architecture rather than the all-new Neue Klasse platform reserved for electric models like the upcoming NA0 i3. That’s not a disadvantage. The current 3 Series chassis is already one of the best in the segment, and BMW claims the suspension geometry and weight distribution have been refined further.
The proportions shift slightly — longer hood, shorter overhangs, bigger trunk — but the bones are familiar.
Spy shots from Nürburgring testing show slimmer kidney grilles, a wide trapezoidal lower intake that echoes the G90 M5’s front fascia, and red-painted M Sport brakes behind 20-inch wheels. Only M Performance and full M variants get visible quad exhaust tips. Everyone else gets smooth, pipe-free bumpers. It’s a clean visual hierarchy that the outgoing generation never quite nailed.
The real question mark is rear-wheel drive. The current M340i offers it in select markets including the U.S., but xDrive outsells it overwhelmingly. Whether BMW bothers keeping the purist option alive remains unconfirmed. Given the brand’s trajectory, don’t hold your breath.
What is confirmed is the death of the third pedal. If the M3 G84 goes automatic-only as rumored, the G50 generation becomes the first 3 Series range with zero manual transmission options. The M340i was never a big manual seller — most buyers toggled through Sport+ and let the eight-speed do its thing — but the option existing mattered. Its absence says something about where the brand’s priorities now sit.
The M340i was always the 3 Series that enthusiasts actually bought. Not the one they argued about online, not the one they poster-walled in their garage — the one they quietly configured at midnight and drove to work Monday morning. It delivered 90 percent of the M3 experience at 75 percent of the price, with half the insurance headache and none of the tire bills.
The M350 looks poised to stretch that equation even further. More power, sharper styling, a better platform, and no M3 sibling to steal its thunder for two full years. If BMW holds pricing anywhere near the current M340i’s window, this becomes the easiest recommendation in the lineup.
Production is months away. We haven’t driven it. But the ingredients are all sitting on the counter, and BMW has been cooking this particular dish long enough to know the recipe.
