Overview
- BMW confirmed the M350 xDrive will replace the M340i as the top internal‑combustion 3 Series and announced provisional outputs of about 326 kW (443 PS / 437 hp), 580 Nm, a 0–100 km/h time of 4.1 seconds, and a 250 km/h top speed.
- The M350 pairs an updated B58 3.0‑litre turbo inline‑six with a 48V mild‑hybrid unit that BMW says boosts low‑end torque and throttle response rather than representing a wholly new engine.
- Drift Moment will let the xDrive system decouple the front axle and send power only to the rear wheels, but BMW says the feature will not be available at launch and will be delivered during 2027 by remote software upgrade to already‑delivered cars.
- BMW fitted the M350 with M‑specific hardware including Adaptive M Suspension, variable sport steering, an electronically controlled rear differential lock, a longer wheelbase and wider tracks to raise handling precision while keeping ride comfort.
- A single, in‑house driving‑dynamics stack (Heart of Joy / Driving Stack) coordinates torque distribution, brakes and stability systems, enabling future capability adds over the air and changing how BMW can update vehicle behavior after sale.
