BMW M340i 2025 Price - Images & Specifications

The BMW M340i is not built for the buyer cross-shopping a Camry or a top-end Creta — it is aimed squarely at the enthusiast who wants a four-door saloon that can embarrass proper sports cars off a traffic light while still ferrying the family to the airport on a Monday morning. This is the quickest, most track-focused version of the 3 Series sold in India short of an actual M3, and it exists for a narrow but vocal audience: driving enthusiasts who value chassis feel and straight-line pace as much as they value badge prestige.

The 3 Series nameplate itself is BMW's longest-running and most important model line, tracing its roots back to the E21 of the mid-1970s and evolving through the E30, E36, E46 and E90 generations into the G20 platform that underpins today's car. Each generation has carried the same brief — a compact executive sedan with genuine rear-wheel-drive dynamics — and the M340i represents the most performance-oriented interpretation of that brief without stepping fully into M3 territory. The M340i sits in an unusual place within that history — it is not a full-blown M3, but it borrows enough hardware from BMW M GmbH to feel like one on a Sunday drive. In global markets the "340i" nameplate has existed since the F30-generation cars, but the "M340i" designation, denoting the M Performance treatment with the M-tuned chassis, brakes and standard xDrive, only arrived with the current G20 generation. In India, where the regular 330i and 320d sell in modest numbers, the M340i occupies a halo position — it is often the version BMW India uses to draw enthusiasts into showrooms even if most walk out with a 320Ld. Being brought in as a fully-built CBU import rather than being locally assembled like the standard 3 Series, the M340i also carries a different ownership proposition: lower volumes, longer wait times when out of stock, and a price that reflects import duty rather than local production economics.

Specification-wise, the M340i is powered by BMW's 3.0-litre B58 TwinPower Turbo inline-six, displacing 2998cc and now running a 48V mild-hybrid system to meet emission norms without blunting response. It produces 374 bhp between 5,800-6,500 rpm and 500 Nm of torque across a broad 1,800-5,000 rpm band, sent to all four wheels through an 8-speed M Steptronic Sport automatic and BMW's xDrive all-wheel-drive system. For Indian buyers used to reading a spec sheet as a checklist, the number that matters most in daily use is not outright power but that torque plateau — it means the M340i never feels like it is waiting for boost, whether pulling out of a Bandra signal or overtaking a truck convoy on the Mumbai-Pune Expressway. The ARAI-rated efficiency figure of 13.76 kmpl looks unremarkable next to a diesel 320Ld, but for a car making supercar-humbling performance, it is a reasonable trade-off, and most owners factor fuel cost as a rounding error against the car's price tag.

Engine & Performance is where the M340i earns its keep. The B58 straight-six is one of the most celebrated modern turbo engines precisely because it does not feel synthetic — throttle response is immediate, the mid-range surge is relentless, and the inline-six's inherent smoothness means it revs cleanly to redline rather than running out of breath like a lot of turbo fours. BMW quotes a 0-100 kmph time in the mid-4-second range, which is quick enough to worry hot hatches costing half as much, and the xDrive system means that performance is deployable on a wet Bengaluru monsoon morning, not just on a dry racetrack. In real-world use, the eight-speed automatic is the unsung hero — it shifts with a directness that older BMW autos lacked, holding gears under hard braking and kicking down instantly when the driver wants it to. What buyers should understand going in: this powertrain rewards being driven, and short city hops without occasionally extending the engine will leave a chunk of its character unexplored. In real-world use, owners on long-term ownership reports note that fuel economy settles around 10-11 kmpl in mixed city-highway driving despite the ARAI-certified figure of 13.76 kmpl — a gap that is typical for a performance-oriented petrol six but worth budgeting for, since this is not a car bought by anyone chasing running costs. The B58 engine's reputation for reliability, built up over years of service in multiple BMW and Toyota Supra applications globally, has largely held up in Indian ownership too, with long-term reports citing the powertrain itself as trouble-free even past the 60,000 km mark.

Ride & Handling is where BMW's engineering intent is most obvious. The M340i's chassis is stiffened over the standard 3 Series, with adaptive M suspension, larger anti-roll bars and quicker steering. On smooth expressway tarmac, the car feels planted and eager to change direction, with none of the vagueness that can afflict all-wheel-drive performance saloons. The trade-off, and it is real, is ride quality on typical Indian roads. The low-profile 225/40 R19 front and 255/35 R19 rear run-flat tyres transmit sharp expansion joints and potholes directly into the cabin — this is not a car that glides over broken city roads the way a 320Ld on smaller wheels does. Owners who live in cities with well-maintained arterial roads will find the trade-off worthwhile; those navigating pockmarked side streets daily may find the firmness wearing after a few months. The 142mm ground clearance, while adequate for most speed breakers taken at an angle, demands caution over unmarked ones. There is a genuine split in how the M340i behaves depending on context: on an open expressway stretch like the Yamuna Expressway or the Bengaluru-Mysuru corridor, the chassis feels like it was built for exactly that road, settling into a confident high-speed gait with steering that loads up naturally through fast sweepers. In dense city traffic, the same firmness that makes the car feel so composed at speed translates into a busier ride over broken patches, expansion joints on flyovers, and unmarked speed breakers — the kind of imperfections that a softer-riding executive sedan on 17-inch wheels would simply absorb. Owners who have run the car for extended periods report that this firmness does not fatigue the way a stiffly-sprung hot hatch might, since the M340i's substantial 1,695 kg kerb weight lends it a planted, damped quality even when the surface underneath is poor.

Features & Tech on the M340i reflect its position as BMW's performance flagship for the segment in India. The 12.3-inch BMW Live Cockpit Professional digital cluster pairs with a 10.25-inch iDrive 7 infotainment screen running wireless Android Auto and Apple CarPlay, and the cabin gets a 16-speaker Harman Kardon sound system, Vernasca or Merino leather upholstery depending on trim, an electric glass sunroof, and a 12-speaker-class ambient experience that feels genuinely premium rather than badge-justified. Safety kit runs to six airbags, 360-degree camera, adaptive LED headlamps with laser light elements, and a full electronic stability suite (DSC, DTC and M xDrive torque vectoring) alongside M compound brakes and M-specific ABS tuning. For Indian buyers, the practical niceties — dual-zone climate control, wireless charging, rear AC vents and power-folding mirrors — matter just as much as the performance hardware, since this remains a car many owners will use for actual family duty alongside weekend blasts. The 480-litre boot, while not class-leading, comfortably swallows a family's luggage for a weekend trip, and the 5-seat cabin, while snugger in the rear than a long-wheelbase Chinese-market 3 Series, offers usable adult space for typical Indian family journeys. Cabin storage, USB-A and USB-C charging points, and a genuinely intuitive iDrive rotary controller — a feature BMW has retained even as rivals move to touch-only interfaces — round out a cabin that feels engineered for daily usability rather than showroom spectacle alone.

Value & Competition places the M340i in an odd spot. Priced from roughly Rs 85 lakh ex-showroom as a fully-imported CBU unit, it sits above mainstream executive sedans and close to genuine performance rivals like the Mercedes-AMG C43 4MATIC, which offers similar power with a four-cylinder hybrid setup and a more track-focused personality, while comparatively, BMW's own 3 Series stablemates — the 320Ld and 330i — cost significantly less but lack the M340i's outright pace and chassis polish. Against segment-mate sedans like the Mercedes-Benz C-Class and Audi A4, the M340i is less about direct cross-shopping and more about buyers who have already decided they want a compact executive sedan with genuine performance credentials and are choosing between BMW and Mercedes' hot versions. Ownership costs bear consideration too — as a CBU import, servicing at official BMW workshops is not cheap, though owners on long-term ownership reports note that BMW's Service Inclusive packages keep costs predictable, with annual outgo averaging in the range of Rs 25,000-30,000 when covered under a plan, and the B58 engine has proven notably reliable over extended ownership periods, with isolated issues like starter motor faults being the exception rather than the rule. It is also worth setting expectations on parts and body repair costs, which run meaningfully higher than a mainstream sedan given the CBU import status — a factor buyers should weigh into total cost of ownership rather than judging the car on sticker price and fuel economy alone. Resale value on low-volume performance imports like the M340i also tends to be less predictable than mainstream 3 Series variants, since the buyer pool for a car this specialised is inherently smaller.

Verdict: the BMW M340i is a car that makes the most sense to buyers who already know they want it — those cross-shopping on practicality alone will find better value elsewhere in BMW's own range or from Mercedes' diesel line-up. But for someone who wants a genuinely quick, all-weather-capable performance saloon that can still handle school runs and airport trips, wrapped in understated styling that doesn't scream for attention the way a full M3 does, the M340i is one of the most complete performance sedans sold in India today. It asks for a firm ride and CBU-level servicing costs in return for a driving experience that few rivals at this price point can match.
