2026 BMW M340i 50 Jahre Edition - A Final Salute to the Sports Sedan Lineage

The BMW 3 Series, since its debut in 1975, has been the undisputed torchbearer of the compact sports sedan segment, defining the template for driver involvement, dynamic balance, and executive appeal. As the model line approaches its fifth decade with the promise of the electrically focused Neue Klasse architecture on the horizon BMW marks this monumental milestone with a truly special offering: the 2026 BMW M340i xDrive 50 Jahre Edition. This highly limited model is less a new chapter in the G20 generation and more a carefully curated love letter to the 3 Series faithful, blending the platform’s peak contemporary performance with deep-cut aesthetic nostalgia.

This review examines the M340i 50 Jahre Edition not merely as a variant, but as a celebratory artifact. It successfully walks a tightrope: retaining the everyday usability and explosive performance of the standard M340i while injecting a level of exclusivity and visual heritage that transforms the car into a highly desirable collector’s piece. For the dedicated enthusiast, this limited edition justifies its premium pricing through rarity and an emotional connection to five decades of Bavarian motoring legend.

The Heart of the Benchmark: Engine and Dynamics

At its core, the 50 Jahre Edition inherits the magnificent mechanical package that has made the current M340i xDrive such a formidable offering: the B58 3.0-litre turbocharged inline-six engine. In an industry increasingly focused on downsized, four-cylinder hybrids, the B58 stands as a monument to BMW’s commitment to the inline-six layout. Producing a robust 387 horsepower and 500 Nm (369 lb-ft) of torque, the engine delivers a silken, linear surge of power that is both effortlessly refined in daily driving and savagely quick when pushed. Paired with the universally lauded ZF 8-speed Steptronic Sport transmission and the rear-biased xDrive all-wheel-drive system, the combination launches the sedan from 0 to 100 km/h in a blistering 4.3 to 4.4 seconds.

Crucially, the B58’s appeal extends beyond mere statistics; it lies in its intrinsic feel and sound. The B58 is, after all, the foundation upon which the mighty S58 engine of the full M3 is built, lending the M340i a true motorsport pedigree. For this special edition, the straight-six symphony is amplified by the standard M Performance exhaust system. This addition provides a deeper, more resonant baritone at idle and a more aggressive bark under hard acceleration a fitting soundtrack for a car that celebrates dynamic excellence. The standard Adaptive M Suspension allows the driver to toggle between compliant touring comfort and stiffened, track-ready aggression, ensuring the 50 Jahre Edition remains versatile. While the power figures are largely unchanged from the standard M340i, the sum of these integrated M Performance parts elevates the driving experience, making it feel slightly sharper and significantly more audible than its non-edition counterpart.

Aesthetic Homage and Curated Exclusivity

The true substance of the 50 Jahre Edition lies in its visual and physical exclusivity, which pays deep homage to the 3 Series’ history. Rather than focusing on performance gains, the edition features design packages anchored by iconic, era-defining BMW Individual paint finishes, many of which are offered for the first time in certain markets, such as the United States.

These heritage colours are the primary differentiator. Enthusiasts will immediately recognize hues like Madeira Red Metallic (a nod to the E36 and E46 generations), the glorious Laguna Green Metallic or Avus Blue Metallic (recalling the E36 M3), and Citrin Black Metallic. These choices are more than just paint; they are a direct chronological linkage to the seminal 3 Series models of the past five decades. Each colour package is meticulously paired with Shadowline trim details, M Shadowline Adaptive LED lights, and the Extended Shadowline Package, which ensure a cohesive, darkly athletic aesthetic.

The exterior is further enhanced by exclusive components from the M Performance catalogue. The 50 Jahre Edition rolls on unique 20-inch forged M Performance wheels, often in a striking Ferric Grey finish, providing an aggressive stance and reducing unsprung weight. The addition of the carbon fiber M Performance rear spoiler—notably distinct from the subtle lip spoiler on the standard car—provides a final, sharp visual flourish. The entire package is subtle, yet impactful, culminating in the commemorative “50 JAHRE EDITION” badge on the trunk lid, signifying its limited production status. With production runs restricted—such as only 100 units slated for Canada—the sheer rarity of this vehicle ensures its status as an instant collectible.

Interior Craftsmanship Meets Modern Technology

The M340i 50 Jahre Edition extends its mandate of exclusivity into the cockpit, offering upgrades rarely seen outside of full M models. For markets like the US, the edition marks the first time Extended BMW Individual Merino Leather upholstery has been made available on a 3 Series sedan. The choice of interior leather colours (often coordinated with the exterior paint, such as Cognac, Tartufo, or contrasting black with M stitching) elevates the sense of luxury and bespoke craftsmanship well beyond the standard Vernasca leather.

These luxurious materials are complemented by tactile and visual cues celebrating the anniversary. The Carbon Fiber Interior Trim adds a sporting, high-tech texture to the dashboard and center console. More subtly, commemorative elements are stitched into the cabin’s narrative: the illuminated "3 Series 50 Jahre Edition" door sills and a unique metal plaque affixed to the cupholder cover serve as constant, quiet reminders of the car's provenance.

While celebrating history, the 50 Jahre Edition does not skimp on modern technology. It comes fully equipped with the latest advancements, including the sweeping BMW Curved Display that seamlessly integrates the 12.3-inch digital instrument cluster and the 14.9-inch touchscreen infotainment system running iDrive Operating System 8.5. Practical features such as the Head-Up Display, Harman Kardon Surround Sound System, Adaptive Cruise Control with Stop & Go, and the Parking Assistance Package Plus ensure that the car is as capable as a luxury daily driver as it is a weekend canyon carver. This blend of historic touchpoints and cutting-edge digital integration is a testament to the 3 Series’ long-standing ability to remain relevant.

Conclusion: An Artifact for the Aficionado

The 2026 BMW M340i xDrive 50 Jahre Edition is an extraordinary automobile that justifies its special-edition status not through revolutionary performance but through impeccable curation and intentional scarcity. It commands a significant premium over the standard M340i, placing it firmly in the territory of a collector’s item.

The value proposition is clear: the buyer is investing in a piece of BMW history. The car is a beautifully executed send-off to the current generation of the iconic sports sedan, wrapped in legendary colours and trimmed with the finest Individual materials. It is a car for the enthusiast who understands the significance of the E21, the E30, and the E46, and who wants a piece of that legacy infused into the excellent modern G20 platform. The 50 Jahre Edition is the perfect celebration: a modern benchmark that humbly nods to the giants upon whose shoulders it stands. It ensures that the legendary B58-powered sports sedan leaves the stage not with a whisper, but with a highly exclusive and resonant final roar.
