In short, the BMW M340i is one of the finest small sport sedans for the money, and in many ways we prefer it to the even more capable M3. Unless you're regularly taking trips to the track and squeezing out every last bit of performance — or really want the bragging rights — the M340i makes more sense.

Pros

Polished handling
Tastefully modern interior with plenty of room
Powerful and fuel-efficient engines

Cons

Ride quality can be a little too firm at times
Most of the 3 Series' advanced driver assist features aren't standard

What's new

Updated exterior styling
Digital instrument panel and larger touchscreen now share a single curved housing
Fewer buttons, with more functions moved to the touchscreen
BMW's Intelligent Personal Assistant gains new functionality
Part of the seventh 3 Series generation introduced for 2019

Overview

The seventh-generation BMW 3 Series has been on sale for a few years, which means it was time for BMW to give it a feature refresh to keep it competitive against the recently redesigned Mercedes-Benz C-Class. We knew a styling update would be in the picture for the 2023 BMW 3 Series and feared the beaver-toothed grille from the 4 Series and M3/M4 would transition to the mild-mannered luxury sedan, too. Thankfully, BMW hasn't fussed with the exterior too much — the grille is slightly wider than before, the headlight cluster no longer has the little notch in the middle, and the front and rear bumpers feature sharper angles, giving it a more modern look.

Cost to Drive^{Cost to drive estimates for the 2023 BMW 3 Series M340i 4dr Sedan (3.0L 6cyl Turbo gas/electric mild hybrid 8A) and comparison vehicles are based on 15,000 miles per year (with a mix of 55% city and 45% highway driving) and energy estimates of $3.92 per gallon for premium unleaded in Virginia.}

There are significant changes to the interior, however. For starters, the 12.3-inch digital instrument panel and central touchscreen now share a singular curved housing running BMW's latest iDrive 8 software. The new software makes the BMW Intelligent Personal Assistant smarter, with improved natural language voice recognition and additional features, including the ability to open and close the windows or the sunroof through verbal commands. Finally, the central screen is upgraded to measure 14.9 inches — nearly double the size of the previously standard 8.8-inch screen — and once again offers touch functionality.

BMW has also streamlined the center stack control layout. There are almost zero dedicated physical controls for the climate system. Instead, these functions are moved to the touchscreen in a climate menu, though the driver and passenger temperatures are always displayed. We're not huge fans of making attention-sapping touchscreens even more convoluted, but at least you can use the car's voice recognition system to change the temperature. The useful set of eight preset buttons, which can be configured for anything from radio stations to navigation destinations and specific menus, also disappears. Lastly, the shift lever has been replaced by a toggle switch.

All these changes make for a compelling entrant into the compact luxury sedan segment, but the 3 Series will face stiff competition from the redesigned Mercedes-Benz C-Class, the stylish Audi A4 and the up-and-coming Genesis G70. Read on for our thoughts on how the updated 3 Series fares.

Our Verdict^{The Edmunds Vehicle Testing Team evaluates a fresh batch of vehicles every week, pairing objective assessments at our test track with real-world driving on city streets, freeways and winding roads.

Rated for you by America's best test team.

Performance

8.5/10

How does the BMW 340i drive? Don't think of the M340i xDrive as a souped-up 330i — it's really more of a baby M3. It blitzes from 0 to 60 mph in 4.1 seconds — much closer to the 3.2 seconds of the M3 Competition than the 5.7 seconds of the 330i xDrive. We pulled nearly 1 g around the skidpad with the Michelin Pilot Sport 4S tires included in our test vehicle's Cooling and High Performance Tire package. The M340i also felt right at home in our tight, winding test circuit, whereas the M3 can feel like too much car.

There aren't really any true downsides to the M340i, though its stopping distance of 110 feet from 60 mph isn't exceptional. Steering is also a touch light and vague in Comfort mode, but there's better communication and heft in Sport mode.

Comfort

8.0/10

How comfortable is the BMW 340i? This particular M340i is an example of how the right spec can separate the merely fine from the exceptional. A previously tested 330i was equipped with the M Sport suspension, which we found punishing on the road. The setup is standard on the M340i, but our test vehicle had adaptive dampers and, wow, what a difference. They effectively make this little sport sedan drivable day to day. Don't even consider an M340i without them.

Otherwise, the standard M sport seats are wonderfully supportive, with cushioning that strikes a perfect balance between firm and comfortable. They feature a range of adjustments, so even taller drivers can dial in the right position without any issue. The ride is quiet, too, with the inline-six settling into a low thrum when you aren't booting the accelerator pedal.

Our only issue is with the climate controls. We like that there are three climate zones by default, but now the front controls are hidden in the touchscreen. As a result, you have to take your eyes off the road to alter the temperature or rely on the sometimes wonky voice control system to do it for you.

Build & price

Interior

8.0/10

How’s the interior? It's easy to get in and out of the 3 Series thanks to ample doorway clearance, and a wide range of seat and steering wheel adjustments afford an excellent driving position for most drivers. The 3 Series is spacious as compact sedans go, with sufficient elbow room for front and rear passengers. Visibility is average, but an array of optional cameras offer added exterior views from several angles.

BMW's iDrive interface looks fantastic, but there are so many features and controls it can sometimes be a maze to navigate. It's easy to discern the fixed buttons and controls, but the console's flat buttons require regular downward glances.

Technology

8.0/10

How’s the tech? The 3 Series' latest iDrive 8 infotainment system looks sharp. Our only gripe with the nav system is that it won't display directional info. So when you search for a Starbucks, you'll see that there's one a mile away, but not necessarily where. Luckily, you can visually locate the right store on the map. The 16-speaker Harman Kardon audio system is very impressive for the price and complements the standard wireless Apple CarPlay and Android Auto.

Storage

7.5/10

How’s the storage? The 3 Series offers 13 cubic feet of trunk space, which is slightly roomier than average for the segment. Only a hatchback like the Audi S5 Sportback would offer 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.

Fuel Economy

9.0/10

How economical is the BMW 340i? According to the EPA, the M340i xDrive will get 26 mpg in combined driving (23 city/32 highway). These numbers are high compared to its direct competitors, and incredible when you consider it has two extra cylinders and nearly 130 hp more than the 330i xDrive, yet fuel economy is dinged just 1 mpg all around.

Value

8.0/10

Is the BMW 340i a good value? This is an expensive luxury sedan, no doubt. But if you compare this against an M3, the M340i offers a similar level of driving excitement for a lot less money. So there's value here if you can do some mental gymnastics. The interior has high-quality materials and our test car had no fitment or build quality issues. BMW's basic and powertrain warranties are typical for the segment.

Wildcard

8.5/10

Our particular version of the M340i was an absolute blast, deftly balancing approachable performance with good road comfort. But previously tested 3 Series variants of this generation haven't been so successful, meaning your mileage may vary if you choose the wrong spec. Our advice? If you're going with the 330i, skip the performance suspension and large-diameter wheels. For the M340i, the adaptive suspension is a must-have.

Which 3 Series does Edmunds recommend?

If you have a spot to plug it in, the BMW 330e is our recommendation. It's price isn't much higher than the base 3 Series, yet it comes equipped with a plug-in hybrid powertrain supplying an estimated 22 miles of pure electric driving before switching to gas-electric hybrid operation.

BMW 3 Series models

The 2023 BMW 3 Series sedan lineup includes the 330i, 330e and M340i. Each one has a slightly different mission. The 330i is the entry-level 3 Series while the 330e is a plug-in hybrid. The M340i is the sportiest and most powerful. Keep reading for our editors' curated breakdown of each trim's powertrain and standard and optional features.

330i
The base trim comes reasonably well equipped with:

Turbocharged four-cylinder engine (255 horsepower, 294 lb-ft of torque)
Eight-speed automatic transmission
Rear-wheel or available all-wheel drive (BMW's xDrive)
18-inch wheels
LED headlights
Power-folding, heated side mirrors
Rain-sensing windshield wipers
Sunroof

330e
The 330e includes all the standard features of the regular 330i but adds a plug-in hybrid powertrain with a turbocharged four-cylinder gasoline engine and an electric motor (combined 288 hp, 310 lb-ft). The EPA estimates it can drive about 22 miles on a fully charged battery.

M340i
The M340i provides a big increase in performance thanks to its larger engine:

Turbocharged six-cylinder engine (382 hp, 369 lb-ft) with 48-volt mild hybrid system
18-inch wheels
Aerodynamic kit
More aggressive front bumper and unique grille
Rear spoiler
M Sport suspension

BMW 3 Series vs. Audi A4

Right out of the box, the Audi A4 is better equipped than the BMW 3 Series, featuring standard leather seats and all-wheel drive. The A4 45 TFSI is quicker to 60 mph than the 3 Series, and the Audi's interior feels high-tech, though the new 3 Series' cabin steps up its tech vibe too. The more conservative Audi A4, though, isn't quite as satisfying to drive as the BMW.

BMW 3 Series vs. Genesis GV70

Hyundai's luxury spinoff brand, Genesis, wanted to build a Korean version of the BMW 3 Series, and the G70 is the result. The Genesis is just as fun to drive and is loaded with value. From performance to tech, the G70 is a credible alternative to the 3 Series. Its back seats and cargo area are smaller in comparison, however.

BMW 3 Series vs. Mercedes-Benz C-Class

The Mercedes-Benz C-Class has long been the 3 Series home country rival, and the redesigned 2022 version is the best one yet. A strong and efficient engine and an effective voice control interface are among the C-Class' highlights. It isn't quite as fun to drive as the 3 Series, but if you value luxury over performance, the C-Class is the way to go.
