BMW M340i 50 Jahre: Inside the 374-hp Limited-Edition Sports Sedan
With only 50 units produced worldwide, the BMW M340i 50 Jahre Edition marks five decades of the 3 Series with a 374-hp inline-six, all-wheel drive, and exclusive details that put it within striking distance of an M3 — without the M3 price tag.

BMW M340i 50 Jahre Edition: 50 Units, 374 Horsepower, and an Anniversary That Became a Collector’s Car
The BMW M340i has always occupied that sweet spot enthusiasts love: close enough to a true M car to feel special, but practical enough to drive every day without constantly second-guessing the purchase. Now BMW has pushed that formula even further with a birthday edition that’s nearly impossible to get.
The 50 Jahre Edition — German for “50 Years” — celebrates half a century of the 3 Series with just 50 units, launched in India in 2025. The foundation is the M340i xDrive G20 LCI, the same inline-six sedan that already earns strong praise on its own merits.
Mechanically, nothing changes from the standard car. The B58 engine producing 374 hp carries over unchanged. What makes this edition special is the combination of exclusive visual details, commemorative badging, and an extremely limited run that turns this BMW into a genuine collector’s piece.
The closest rivals in this segment are the Mercedes-AMG C43 and the Audi S5 Sportback, but the M340i tends to stand out for its balance between outright performance and everyday livability. No official U.S. release has been announced.
Built to Look the Part: The M340i 50 Jahre Edition’s Exterior Design
The standard M340i is already far from subtle. The 50 Jahre Edition takes that same visual intent and adds another layer of purpose — without going overboard.
Up front, the redesigned G20 LCI grille gets the darkened treatment from the M High-Gloss Shadowline package, paired with the inverted “L” DRL signature and an aggressive front bumper that sits noticeably lower than what you’d find on a regular 3 Series. The “50 Jahre BMW M” badges on the grille make the statement before you even reach the door handle.
Along the sides, 19-inch M wheels in Jet Black are the standout element. Paired with red M Sport brake calipers, they create that contrast enthusiasts recognize immediately — the kind of detail you notice in a parking lot from twenty feet away. The body lines follow the G20 template, with proportions that balance athletic and formal in a way most European sedans aim for but don’t always nail.
Around back, the rear spoiler, sport bumper, and commemorative badges close the loop on a design that reads consistently aggressive from every angle.
Color options include Dravit Grey, Black Sapphire, Fire Red Metallic, and Arctic Race Blue — all paired with the darkened exterior trim from the Shadowline package. At 185.6 inches long and 71.9 inches wide, this is a genuinely commanding presence on the road without crossing into oversized territory.
The result is a sedan that looks athletic at a stoplight and professional in a corporate parking garage. Muscular, but measured.
Inside the M340i 50 Jahre: A Cabin Built Around the Driver
Settling into the M340i 50 Jahre Edition makes the car’s priorities immediately clear. The Vernasca leather sport seats with contrasting stitching and M tricolor stripes put the driver front and center from the moment you close the door.
Interior trim combines carbon fiber accents with a dark headliner, following BMW’s M Performance design language without being flashy about it. Material quality sits firmly at the top of what you’d expect from a non-M BMW flagship — nothing feels like a cost-cutting shortcut.
The dashboard centers around the BMW Curved Display, a single flowing panel that integrates a 12.3-inch digital instrument cluster with a 14.9-inch infotainment screen. It’s one of the cleaner executions of dual-screen design in the segment, and it holds up well compared to what Mercedes and Audi offer at this price point.
Tech-Forward and Connected: iDrive 8 and the Features That Matter
The BMW OS 8/8.5 system brings wireless Apple CarPlay, Android Auto, an AI-powered personal assistant, connected navigation, and over-the-air software updates. The augmented reality head-up display is a genuine highlight — it projects navigation cues and speed data directly into the driver’s sightline, reducing the need to glance away from the road.
Active safety coverage is thorough: autonomous emergency braking, adaptive cruise control, lane-keeping assist, blind-spot monitoring, traffic jam assist, and 360-degree camera coverage. For a performance-focused sedan, it’s a level of driver assistance that goes beyond what most buyers in this segment would expect.
Rear-seat space is adequate for two adults on longer trips. Three across is a tighter fit. The 480-liter trunk — roughly 17 cubic feet — is competitive for a sport sedan and handles real-world use without complaints.
Real standout: the display system and BMW’s OS integration rank among the best in class. Real limitation: rear-seat access and legroom fall noticeably short of long-wheelbase competitors, and three adults in back will feel the squeeze quickly.
The Engine That Makes the M340i 50 Jahre Worth Talking About
The heart of the M340i 50 Jahre Edition is the B58 3.0-liter turbocharged inline-six paired with a 48-volt mild-hybrid system. This is precisely the engine combination that earns the car its “almost M3” reputation — and after spending time with the numbers, it’s easy to understand why.
Official output for the Indian market sits at 374 horsepower and 369 lb-ft of torque, available from just 1,900 rpm all the way to 5,000 rpm. That wide torque band is the key detail: power delivery is broad and consistent, not a narrow peak that demands constant gear-hunting to access. The car pulls hard from everyday speeds without needing to be wrung out.
The 8-speed Steptronic Sport automatic handles both ends of the spectrum well — smooth enough for city commuting, quick enough to feel engaged when you push it. Paddle shifters on the wheel give manual control when the moment calls for it. The xDrive all-wheel-drive system runs with a rear-biased tune and an M Sport differential, keeping handling feel intact while adding the traction security that makes the car genuinely usable year-round.
On the clock, BMW claims 0–60 mph in approximately 4.3 seconds, with a top speed electronically limited to 155 mph. Independent tests by Autocar India confirmed numbers very close to those figures in real-world conditions.
Fuel economy is rated at approximately 32 mpg on the Indian ARAI test cycle. The mild-hybrid setup contributes meaningfully during light acceleration and coasting, keeping that number reasonable for an engine of this output.

What the BMW M340i 50 Jahre Actually Costs — and What That Means for American Buyers
At launch in India, the 50 Jahre Edition was priced at approximately 76.9 lakh rupees, which translates to roughly $92,000 USD at current exchange rates. The standard M340i in the same market starts around 72.8 lakh, making the anniversary edition a modest premium over the base car for a significant jump in exclusivity.
For context, the closest rivals in that market sit noticeably higher: the Mercedes-AMG C43 runs between $113,000–$119,000 USD equivalent, and the Audi S5 Sportback lands around $88,000–$93,000 USD equivalent. The BMW positions itself as the most performance-per-dollar option of the three — a pattern that holds across most global markets where these cars compete directly.
There is no confirmed U.S. availability for the 50 Jahre Edition. Anyone stateside looking to acquire one would need to go the private import route, which adds substantial cost through federal compliance requirements, customs duties, and the ongoing challenge of sourcing the edition-specific trim pieces if anything needs replacing down the road.
Maintenance costs follow the expected profile for a BMW M Performance model: high by mainstream standards. The B58 engine, 19-inch sport tires, and M Sport brakes all carry service costs that put the M340i firmly in the premium tier — above a standard 330i and in the same general range as the S5 and C43.
Insurance lands in a similarly elevated bracket. High horsepower, all-wheel drive, premium replacement parts, and strong resale value push this car into a risk category that insurers treat similarly to the AMG and Audi alternatives. Clean driving history and low annual mileage help, but expect to pay noticeably more than you would for a conventional luxury sedan.
Is it worth buying now? For a collector or enthusiast who values documented exclusivity with real performance credentials — yes, the case is there. For someone prioritizing rational daily-driver value, a standard M340i through official channels makes considerably more financial sense.
The target buyer is someone who wants a genuinely rare sport sedan, doesn’t need the full M3 experience, and is willing to cover the cost of exclusivity over the long term.
What to Know Before You Buy: BMW M340i 50 Jahre Edition FAQ
What is the real-world fuel economy of the BMW M340i 50 Jahre Edition? The certified rating is approximately 32 mpg on the ARAI test cycle. In heavy urban driving, expect figures closer to 18–22 mpg, which is reasonable for a 374-hp engine with all-wheel drive.
Is the BMW M340i 50 Jahre Edition coming to the United States? Not officially. All 50 units were produced exclusively for the Indian market. U.S. buyers would need to pursue a private import, which adds significant cost and regulatory complexity.
Who are the main competitors of the M340i 50 Jahre Edition? The primary rivals are the Mercedes-AMG C43 and the Audi S5 Sportback. In head-to-head comparisons, the BMW typically leads on real-world acceleration and the balance between sport and comfort, while costing less than the AMG in most markets.
Is insurance expensive on the BMW M340i? Yes. Between the high horsepower output, AWD system, imported parts costs, and strong market value, the M340i falls into a high-risk insurance tier — similar to the C43 and S5 Sportback. A clean driving record and low annual mileage can reduce the premium, but expect to pay significantly more than a standard luxury sedan.
Is the BMW M340i 50 Jahre Edition Worth the Investment?
For the enthusiast who wants documented exclusivity paired with genuine performance, this car delivers. It covers 0–60 in around 4.3 seconds, comfortable enough for daily use, and carries a numbered 1-of-50 build plate that means something to people who follow this segment closely.
It’s not the right call for buyers prioritizing space for a growing family, low maintenance overhead, or straightforward ownership costs. And for anyone in the U.S. hoping to add one to the garage without a major import effort — this one will test your patience and your budget.
The M340i 50 Jahre doesn’t try to be the loudest car in the room. It tries to be the most complete — and on that metric, it makes a strong case.
