BMW is preparing to give the next-generation 3 Series a serious performance upgrade. The new range-topping BMW M350 will produce 437bhp from a turbocharged 3.0-litre inline-six, making it significantly more powerful than the outgoing M340i while introducing a feature previously reserved for BMW’s full M cars: a dedicated drift mode.

Positioned below the next-generation BMW M3, the M350 is set to become the fastest and most powerful combustion-engined version of the regular 3 Series when it arrives. With all-wheel drive, an eight-speed automatic transmission and a 0-62mph time of just 4.1 seconds, the new M350 promises to blur the line between a conventional sports sedan and a full-blown performance car.
BMW M350 Gets 437bhp From a Turbocharged Inline-Six
At the heart of the new BMW M350 is BMW’s familiar turbocharged 3.0-litre straight-six petrol engine. According to BMW, the engine will deliver 437bhp and 428lb ft of torque.
That represents a substantial increase over the outgoing BMW M340i, with the new model gaining 50bhp and 30lb ft of torque.
The M350 will be the only regular 3 Series derivative, alongside the forthcoming M3, to use BMW’s signature six-cylinder petrol engine. Other combustion-powered versions of the next-generation 3 Series are expected to rely on updated four-cylinder petrol and diesel engines.
The additional power puts the M350 firmly into performance-car territory while retaining the everyday usability that has long defined the 3 Series.
0-62mph in 4.1 Seconds
Power will be delivered to all four wheels through BMW’s familiar eight-speed automatic transmission and xDrive all-wheel-drive system.
BMW claims the new M350 will accelerate from 0 to 62mph in just 4.1 seconds. That makes it only 0.6sec slower than the outgoing M3, despite the M350 being positioned below BMW’s full-performance M model.
Top speed will be electronically limited to 155mph.
The figures underline just how far the M350 has moved beyond the traditional executive-sports-sedan formula. With 437bhp, substantial torque and all-wheel drive, the new BMW will have enough performance to challenge some cars that previously occupied a much higher performance bracket.
BMW M350 Drift Mode Is a First
Perhaps the most surprising addition to the new BMW M350 is its drift mode.

For the first time, BMW will bring this feature to a non-M 3 Series derivative. Previously, the ability to deliberately send power exclusively to the rear wheels in a dedicated drift setting was associated with BMW M models such as the M3.
When activated, the system can direct all of the engine’s drive to the rear axle, making it significantly easier for the driver to induce and control a slide.
There is one catch, however. The BMW M350 drift mode will not be available from launch. Instead, BMW plans to introduce the feature through a software update scheduled for next year.
That approach highlights how increasingly important software has become to modern performance cars. Rather than requiring a hardware change, BMW can unlock additional driving functionality through an over-the-air update.
Steel Suspension Standard, Adaptive Dampers Optional
Despite its performance credentials, the M350 will retain a conventional steel-spring suspension system as standard.
Buyers will be able to upgrade to one of two adaptive damper systems. One will prioritize comfort and everyday usability, while the other will feature a firmer setup with BMW M branding and a greater focus on performance driving.
The choice could make the M350 particularly appealing to buyers who want a single car capable of handling both daily commuting and fast driving on demanding roads.
BMW will also equip the M350 with a staggered sports-tyre configuration. The front axle will use 245mm-wide tyres, while the rear tyres will measure 275mm across.
The wider rear rubber should help the M350 put its 437bhp to the road while also contributing to the car’s more aggressive handling characteristics.
New BMW 3 Series Launches With Petrol and Electric Power
The BMW M350 will form part of an entirely new generation of the 3 Series.

BMW is expected to launch the electric i3 first, followed by the combustion-engined versions of the next-generation 3 Series later this year. UK deliveries of the petrol-powered models are expected to begin in early 2027.
The strategy reflects BMW’s decision to develop the next 3 Series around multiple powertrain technologies rather than moving exclusively toward electric propulsion.
As a result, buyers will be able to choose between electric and combustion-powered versions of BMW’s iconic compact executive sedan.
Will BMW Bring Back the M340d?
One major question remains unanswered: will BMW introduce a successor to the M340d?
The previous-generation 3 Series offered the M340d, combining BMW’s performance-oriented M treatment with a powerful diesel engine. However, the chances of seeing an M350d—or an equivalent high-performance diesel—appear increasingly slim.
Diesel-powered passenger cars have continued to lose popularity in many European markets, while increasingly stringent emissions regulations are making high-performance diesel applications more difficult to justify.
The upcoming Euro 7 emissions regulations could further complicate the business case.
BMW’s decision to remove the “i” suffix from petrol-powered model names is also noteworthy. Historically, the “i” designation distinguished petrol models from diesel versions carrying a “d” suffix. Its removal could signal a broader change in the way BMW identifies its combustion-powered cars—and potentially the disappearance of some diesel variants.
Four-Cylinder Engines for Other 3 Series Models
While the M350 will retain BMW’s six-cylinder performance engine, the rest of the combustion-powered 3 Series range is expected to use four-cylinder powerplants.

These engines are likely to be updated versions of BMW’s existing B48 petrol and B47 diesel families, which are already used in the current-generation 3 Series.
This creates a clear hierarchy within the new range: four-cylinder engines for mainstream models, the 3.0-litre straight-six for the M350, and a substantially more powerful M3 sitting above them.
Next-Generation BMW M3 Will Offer Petrol and Electric Power
The arrival of the M350 is only part of BMW’s larger performance strategy.
The next-generation BMW M3 is expected to arrive in 2027 and will be offered with both petrol and electric power. BMW M boss Frank van Meel has already described the forthcoming electric M3 as the petrol-powered car’s “own natural enemy.”
The electric M3 is expected to use a quad-motor powertrain, giving BMW the ability to independently control the torque delivered to each wheel.
That could create a completely different approach to performance and handling compared with the traditional rear-biased dynamics of the combustion-engined M3.
For enthusiasts, the relationship between the M350, petrol M3 and electric M3 could become one of the most interesting aspects of BMW’s next-generation performance lineup.
BMW M350 vs M3: How Close Will They Be?
On paper, the M350 is already remarkably close to the outgoing M3 in straight-line performance.

Its 437bhp output and 4.1-second 0-62mph time mean that the gap between the two cars is considerably smaller than the model hierarchy might suggest.
The M3 will remain the more serious performance machine, with a chassis, brakes, aerodynamics and powertrain engineered specifically for BMW M’s highest level of road and track performance.
But the M350 could occupy an increasingly attractive middle ground. It promises near-M3 acceleration while offering the comfort, practicality and understated character expected from a regular 3 Series.
The addition of a rear-wheel-drive drift mode makes the comparison even more intriguing.
A New Era for the BMW 3 Series
The next-generation BMW 3 Series is shaping up to be one of the most technologically significant versions of the model yet.
The M350 combines a 437bhp turbocharged straight-six, xDrive all-wheel drive, an eight-speed automatic transmission, adaptive suspension options and—eventually—a dedicated drift mode.
More importantly, BMW is maintaining a combustion-powered performance option at a time when the automotive industry is rapidly transitioning toward electric vehicles.
The result could be a BMW M350 that serves as a final high-performance expression of the traditional six-cylinder 3 Series formula before electric power becomes increasingly dominant.
With the next M3 arriving soon and an electric four-motor M3 promising an entirely different approach to performance, BMW’s new 3 Series family could offer enthusiasts more choice than ever—while simultaneously marking the beginning of a major shift in what a performance BMW can be.
