BMW M350 xDrive Debuts with 443 HP and Future-Proof Drift Mode

BMW has confirmed powertrain details for the new M350 xDrive, the top-tier combustion engine model in the next-generation 3 Series. The vehicle features a 3.0-liter twin-turbocharged inline-six engine producing 443 horsepower and 428 lb-ft of torque, paired with a 48V mild-hybrid system. It achieves 0-62 mph in 4.1 seconds. A key innovation is 'Drift Moment,' a rear-wheel-drive mode arriving via over-the-air update in 2027, allowing the car to simulate pure rear-drive dynamics despite its standard all-wheel-drive setup. The car shares the Neue Klasse design language with the electric i3 but retains distinct mechanical advantages for combustion engines.
Key points
- The M350 xDrive uses the latest B58 3.0-liter twin-turbocharged inline-six engine, delivering 443 hp and 428 lb-ft of torque.
- It is equipped with a 48V mild-hybrid system and standard all-wheel drive, achieving 0-62 mph in 4.1 seconds.
- A 'Drift Moment' feature will be added via a 2027 software update, enabling full rear-wheel-drive dynamics for drifting.
- The car shares the Neue Klasse design platform with the electric i3 but has a longer wheelbase, wider track, and different proportions to accommodate the engine.
- BMW emphasizes the 'Driving Stack' system, which integrates chassis, brakes, and differentials for precise handling, distinct from the EV 'Heart of Joy' controller.
Background
Previous coverage in August and September 2026 confirmed that BMW is retaining combustion engines in the 3 Series lineup alongside electric models. Earlier reports noted the M350 would feature a 3.0-liter engine and mild-hybrid technology, with the Drift Mode arriving later via software update. The current news confirms specific power figures and the timeline for the Drift Mode release.
How outlets are covering it
The Drive highlights the return of the 'i' branding removal and the excitement around the B58 engine's performance. Top Gear provides a detailed driving impression, noting the car's superior handling compared to the previous M340i and praising the engine's sound and throttle response. PistonHeads focuses on the competitive aspect, noting the power increase likely responds to the Mercedes C53, and emphasizes the novelty of the rear-drive Drift Mode. All sources agree on the core specs but differ in emphasis: The Drive focuses on the news leak, Top Gear on the driving experience, and PistonHeads on the market positioning and software features.
Why it matters
The M350 xDrive represents BMW's strategy to maintain a strong combustion engine lineup while transitioning to electric vehicles. The inclusion of a Drift Mode via software update demonstrates how software is enhancing traditional driving dynamics, offering a unique experience that bridges the gap between all-wheel-drive stability and rear-wheel-drive agility. This move ensures the 3 Series remains competitive in the performance segment against rivals like the Mercedes C53.
What to watch
The Drift Mode is expected to arrive via an over-the-air update in 2027. Full production details and pricing are likely to be announced closer to the car's launch. BMW may also introduce other variants, including a plug-in hybrid 330e, in the coming year.
