BMW M340i to be Replaced by All-New M350 xDrive: Next-Gen Details Revealed

For driving purists and track enthusiasts in India, the BMW M340i has long been regarded as the ultimate sweet spot—delivering supercar-scaring acceleration, a symphonic inline-six exhaust note, and daily usability at a price far below the full-blown M3. However, an era is coming to a close: BMW is officially retiring the ‘M340i’ badge, preparing to replace it with the all-new BMW M350 xDrive.

What We Know About the Upcoming BMW M350 xDrive

1. Upgraded 3.0L B58 Turbo Straight-Six

The celebrated 3.0-litre turbocharged inline-six engine (B58) receives extensive internal revisions:

• Integrated second-generation 48V mild-hybrid electric motor mounted inside the transmission housing for instant torque fill.
• Output climbs past 392 bhp and 540 Nm of torque.
• 0–100 km/h acceleration drops to an astonishing 4.2 seconds.
• Rear-biased xDrive All-Wheel Drive system paired with an M Sport electronic locking differential.

2. True Quad Exhaust System

Historically reserved only for full ‘M’ cars (like the M3 and M5), the upcoming M350 will adopt quad circular exhaust pipes exiting aggressively from an aerodynamic rear diffuser, signalling its performance intent.

3. Dropping the ‘i’ Moniker

In line with BMW’s modern nomenclature strategy, petrol-powered models will drop the ‘i’ suffix (which was originally used for ‘fuel injection’ and is now reserved exclusively for electric i-series vehicles like the i4, i5, and i7). Hence, the performance model becomes simply the **M350 xDrive**.
