The seventh generation of BMW’s legendary compact executive sedan introduced something truly special with the BMW M340i. A car that brings the amazing thrill of breathtaking driving to your everyday life. This is achieved without giving less luxury and sophistication. If you’re like me and love the rush of acceleration but also enjoy a comfy ride, the BMW M340i might just be your dream car.
Design and Aesthetics
Exterior Design
Let’s be honest here, the first thing that attracts you to a car is its looks, right? Well the BMW M340i doesn’t disappoint. It’s got that perfect blend of elegance and sportiness. Picture this, the regular kidney grille, but this time it’s bigger, bolder, and has a unique mesh design that adds a fierce touch. The LED headlights, with their sharp curves and upside-down L arrangement, give the car a modern, aggressive feeling like it’s always ready to pounce.
From the side, the car’s long wheelbase and short overhangs give it a dynamic silhouette that’s hard to ignore. The standard 19-inch alloy wheels aren’t just for show; they add to the car’s athletic stance, making it look like it’s moving even when it’s parked. And when you get to the back, those trapezoidal exhaust outlets and the large rear diffuser make it clear: this car is built for speed.
Interior Features and Comfort
Step inside, and the M340i greets you with a cabin that’s all about luxury meeting sportiness. The leather upholstery feels rich, and those Alcantara accents add just the right amount of flair. The M-specific sports seats? They’re the kind you sink into and never want to leave. Whether you’re on a quick city drive or a long road trip, these seats offer the perfect mix of support and comfort.
One of my favorite parts? The BMW Curved Display. It’s this sleek, integrated unit that combines a 14.9-inch infotainment screen with a 12.3-inch digital instrument cluster. It’s not just about looks, though—this setup makes it super easy to access everything from navigation to your favorite playlists without taking your eyes off the road for too long.

Unique Design Elements
But it’s the little things that set the M340i apart. Take the M leather steering wheel, for example. It’s got contrasting stitching and integrated shift paddles that make you feel connected to the car in a way that’s hard to describe until you’ve driven it. And those M-specific interior trims? They’re a constant reminder that you’re in something special, something built with a driver like you in mind.
Engine and Performance
Engine Details
Now, let’s talk about what really makes the M340i tick: the engine. At the heart of this beast is a 3.0-liter inline-six with BMW’s M TwinPower Turbo technology. This isn’t just an engine; it’s an orchestra of power, delivering 382 horsepower and 500 Nm of torque. And let me tell you, when you step on the gas, you feel it. Whether you’re merging onto the highway or taking off from a stoplight, the M340i responds with a kind of effortless power that puts a grin on your face every time.
Performance Stats
- Acceleration (0-100 km/h): A thrilling 4.4 seconds
- Top Speed: Electronically limited to 250 km/h
- Fuel Economy: About 8.5 liters per 100 km (combined)
The M340i isn’t just about raw power, though. It’s about how that power is delivered. The 8-speed Steptronic Sport transmission shifts so smoothly that you might not even notice it unless you’re in Sport or Sport+ mode, where the car tightens up and gives you a more visceral driving experience. And with the M Sport differential working its magic, you get optimal traction and stability, no matter the road conditions.

Driving Experience
Driving the M340i is an experience in itself. It’s like the car adapts to your mood. Feeling laid-back? Switch to Comfort mode, and enjoy a smooth, quiet ride. But if you’re in the mood for some fun, flip it into Sport or Sport+, and suddenly, the car transforms. The suspension stiffens, throttle response sharpens, and the exhaust note deepens, reminding you that this car is ready to play.
Technology and Infotainment
Model-Specific Technology Features
BMW’s latest iDrive 7 infotainment system is the brains behind the M340i. It’s got everything you need to stay connected on the go, whether that’s Apple CarPlay, Android Auto, or advanced driver assistance features like adaptive cruise control and lane-keeping assist. And the surround-view camera system? It’s like having eyes all around the car, making parking and tight maneuvers a breeze.
Optional Packages
Want to take things up a notch? The M340i offers some tempting optional packages. The M Technology Package, for instance, enhances powertrain cooling and upgrades the brakes, because sometimes, you just need that extra bit of performance. Or go for the Executive Package, which adds a heated steering wheel, remote engine start, and acoustic glazing that makes the cabin so quiet, that you’ll forget you’re driving a performance car.
Practicality and Comfort
Cabin Space and Cargo
For all its performance, the M340i doesn’t skimp on practicality. There’s plenty of room for five passengers, with enough legroom to keep everyone happy. And with 480 liters of cargo space in the trunk, you’ve got more than enough room for luggage, groceries, or whatever else life throws your way. I once packed this car for a weekend getaway, and I didn’t have to leave anything behind, even with my wife’s “just in case” bags!

Comfort Features
Comfort is a given in the M340i. From the three-zone automatic climate control to the ambient lighting that sets the perfect mood, everything is designed to make your drive as enjoyable as possible. And let’s not forget the premium Harman Kardon sound system, It’s like having a concert hall on wheels.
Efficiency and Environmental Impact
Fuel Efficiency
Performance cars aren’t known for their fuel efficiency, but the M340i does pretty well, sipping about 8.5 liters per 100 km. It’s a nice balance between having fun behind the wheel and not having to stop at every gas station along the way.
Emission Standards
BMW has also packed the M340i with eco-friendly tech to keep emissions in check. Turbocharging, high-precision fuel injection—it all works together to make sure you’re not just driving fast, but driving clean.
Pricing and Value Proposition
Price Range
The BMW M340i starts at around $56,000. For what you get, performance, luxury, and tech, it’s a solid deal. It’s the sweet spot in the G20 3 Series lineup, offering way more excitement than the 330i or 320i without the higher price tag of the M3.
Comparison with Other Models
Compared to its siblings, the M340i is a clear step up in performance. It’s like getting a taste of the M experience without going full-on M3. If you want something that’s both thrilling and practical, this is it.
Optional Extras
