The 2025 BMW M340i might be the middle child in the 3 Series lineup, but it delivers an engaging, fun and highly refined driving experience. Its asking price can feel a bit steep, but the M340i is a well-rounded package.Read full review
The 2025 BMW 3 Series gets some slight tweaks to make it more compelling than its last update in 2022. It's now simplified to just two models: the entry-level 330i and the performance-oriented M340i. The plug-in hybrid version, the 330e, has been discontinued for 2025. The 3 Series is still a great all-around luxury sedan with a solid-built interior and excellent technology.
Edmunds Expert Rating

Very Good
7.4
out of 10
We drove the BMW 3 Series on our test track and on real roads. Our Edmunds team conducts rigorous independent vehicle testing, driving 500,000 miles a year.
Driving experience
7.8/10
How does the BMW 3 Series drive? The M340i might not pack the punch and all the performance hardware of the more serious M3, but that doesn't mean it's not a load of fun to drive. Our test car was a rear-wheel-drive version, and it had no problem sprinting to 60 mph in just 4.8 seconds. Its powerful turbocharged six-cylinder engine is buttery smooth in everyday traffic but still capable of reaching over 113 mph in the quarter mile. That's booking. Outright braking and handling numbers were limited by the M340i's narrow tires, but in less enthusiastic driving environments, the BMW returns confident and composed performance worthy of its badge and its price tag.
In general, driving a 3 Series is pretty easy. The transmission shifts smoothly and unobtrusively. Outward visibility is pretty good, especially if you get the optional surround-view parking camera system. We also like how the optional hands-free highway driving system can reduce the tedium of driving in slow-moving highway traffic.
Comfort
7.4/10
How comfortable is the BMW 3 Series? It's easy to get in and out of the 3 Series thanks to big door openings and a wide range of seat and steering wheel adjustments. The 3 Series is spacious as small sedans go, with sufficient elbow room for front and rear passengers. We also like the 3 Series' quiet cabin at highway speeds and effective climate system that easily keeps you cool on hot days.
In-cabin tech
9.7/10
How’s the tech? BMW puts most of the car's controls in the quick and responsive touchscreen. You can also access them by using voice commands or the control knob on the center console. While we prefer physical buttons, we like the customizable interface.
You can connect your phone to the car through wireless Apple CarPlay and Android Auto. The initial pairing with Apple CarPlay proved a little more complicated than we're accustomed to in our testing. Luckily, it's a one-and-done affair, and it worked fine once connected. Wireless charging is also standard.
Storage & cargo
8/10
How’s storage and cargo? The 3 Series has a 16.9-cubic-foot trunk, which is slightly roomier than average for a small luxury sedan. Only a hatchback like the Audi A5 Sportback offers a significantly larger cargo area. A folding 40/20/40-split rear seat lies nearly flat and adds versatility.
In-cabin storage isn't abundant, but there's enough to go around between the door pockets and center console. One phone can find a home in the wireless charging tray. Easily located LATCH anchors make it a breeze to install a car seat base, but the 3 Series' inherently compact size might force a front seat occupant to move forward if you need to place a rear-facing car seat.
Value
6.7/10
Is the BMW 3 Series a good value? The 3 Series feels like a modern vehicle inside and out. The cabin is full of impressive materials, and the build quality is pretty much the best you'll find in this class of vehicle. But BMW's warranty isn't anything special, and many of the car's desirable features are optional. For example, you'll need to pay extra to get the surround-view camera system, parking sensors and even adaptive cruise control. Rival sedans, such as the Acura TLX and Lexus IS, give you more features for less money.
MPG
5/10
How’s the fuel economy? The EPA estimates that the M340i gets 29 mpg in combined city/highway driving. Any sport luxury sedan that can pull off nearly 30 mpg is a great starting point. In practice, we've found this engine to be remarkably efficient and capable of hitting its consumption numbers with ease.
X factor
9/10
The current 3 Series generation has held up well over time. BMW has kept it fresh with tech and powertrain updates that make it feel modern among its competitors. While the fire-breathing M3 might seem like the only option in the 3 Series lineup, the M340i offers a very satisfying balance of straight-line performance, entertaining handling and everyday comfort.

2025 BMW 3 Series M340i xDrive pricing in Ashburn, VA
The 2025 BMW 3 Series sedan lineup has two models: the 330i and the M340i. Each one has a slightly different mission. The 330i is the entry-level 3 Series while the M340i is the sportiest and most powerful. Compare the 2025 BMW 3 Series trim levels in-depth.
Which 3 Series trim does Edmunds recommend?
We recommend the entry-level 330i for most people since its four-cylinder packs a strong punch and this model gets all of the important technology hardware that we love on the 3 Series. But if you want a little bit more oomph out of your sport sedan, the M340i is a fantastic option to let you have a lot of fun behind the wheel without having to pay M3 prices.
Competitors to consider
Mercedes offers a formidable competitor with the C-Class. It's a touch more luxurious inside than the BMW and offers a similar list of tech features. Additionally, Audi just unveiled a brand new A5, which will replace the longstanding A4 as the company's midsize sedan. Then there's the Genesis G70 and the Lexus IS, though both of these options are getting up there in age with less competitive equipment.
Edmunds spotlight: Changes to the new 3 Series
The latest BMW infotainment system has new software with redesigned menu layouts for quicker interactions. Under the hood, the M340i receives a touch more horsepower, along with mild hybrid technology for quicker response and slightly better fuel economy.
