BMW is strongly associated with luxury sport coupes and convertibles. The company practically invented the modern interpretation of this class with its 3 Series. Four years ago, the 4 Series replaced the 3 Series coupe and convertible in name, but not in spirit. The 4 Series has been delivering all the performance, refinement and strength of its predecessor.

Recently, however, the competition has stepped up its game. You've also got redesigned versions of the Audi A5 and S5 and the Mercedes-Benz C-Class coupe to consider. In our opinion, these rivals have unseated the 4 Series from the top spot in the class, but not by a significant margin. This could be partially attributed to the 2018 BMW 4 Series' age, even though it's updated this year. The changes just aren't significant enough to push it to the top. Overall, though, the 4 Series remains a solid choice for a luxury sport coupe or convertible.

Trim levels & features

The 2018 BMW 4 Series is available in three body styles: a coupe, convertible and four-door Gran Coupe. Within these models, you can choose between the 430i or 440i trims that differ mostly by engine type. The 430i is powered by a turbocharged 2.0-liter four-cylinder engine (248 horsepower and 258 pound-feet of torque), and the 440i receives a turbocharged 3.0-liter six-cylinder engine (322 hp and 332 lb-ft). All of these 4 Series models come with an eight-speed automatic transmission that sends power to the rear wheels, though you can get a six-speed manual on the coupe as an option. BMW's xDrive all-wheel-drive system is also offered as an option.

Standard features for the 430i include 18-inch wheels, automatic LED headlights and foglights, a sunroof (coupe), power-folding and heated mirrors, auto-dimming mirrors, automatic wipers, selectable drive modes, cruise control, a rearview camera, BMW's Assist eCall emergency telematics and smartphone app control over some car functions.

On the inside, you get dual-zone automatic climate control, simulated leather upholstery, 10-way power-adjustable front sport seats, 40/20/40-split folding rear seats, a tilt-and-telescoping steering wheel, a universal garage door opener, BMW's iDrive infotainment system, a 6.5-inch display, a rearview camera, Bluetooth phone and streaming audio, and a nine-speaker audio system with a CD player, HD radio and a USB input.

The 440i adds keyless entry and ignition and a premium 16-speaker Harman Kardon surround-sound audio system with satellite radio. These features are options on the 430i. Convertible models have a power-operated retractable hardtop with a removable wind deflector.

Notable options include various sporty exterior touches, adaptive headlights, automatic high beams, an M Sport or adaptive suspension, an automated parking system, a head-up display, a navigation system, premium leather upholstery, heated front seats, a power rear sunshade, a surround-view camera system, Apple CarPlay and a wireless charging pad. On the safety front, you can also add front and rear parking sensors, blind-spot monitoring, forward collision warning and mitigation, a lane departure warning system and adaptive cruise control.

Trim tested

Each vehicle typically comes in multiple versions that are fundamentally similar. The ratings in this review are based on our First Drive of the 2018 BMW 440i Coupe (turbo 3.0L inline-6 | 8-speed automatic | RWD).

Driving

The BMW 440i used to be the top dog in the luxury sport coupe class, but recent redesigns from Mercedes and Audi have it playing second fiddle. That said, the 4 Series remains an excellent sport touring car that will exceed most drivers' expectations.

Acceleration

The 440i produces an overabundance of power. Acceleration is effortless, with smooth and quick gear changes. To a slightly lesser degree, the 430i also confidently gathers speed and will certainly satisfy most drivers.

Braking

The brake pedal has a reassuring weight and is very intuitive, whether you're driving hard on a twisty road or just cruising to a smooth stop on the boulevard.

Steering

3.5

Steering effort is light in parking lots and gets appropriately weightier as your speed builds. There's not much feedback to the driver, though it is hard to come by in any car nowadays. On the highway, the 4 Series tracks true and needs very little driver input to stay in the lane.

Handling

3.5

On a curvy mountain road, the 4 Series instills a lot of confidence and should satisfy more enthusiastic drivers. Adding the sport and adaptive suspension options further enhance this feeling. Non-sporty drivers will find this reassuring in evasive maneuvers.

Drivability

The 4 Series is easy to drive in any condition or situation. The selectable drive modes aren't as drastically different as rivals, but drivers of any persuasion will easily find their preferred setting. It's a highly capable and accessible vehicle.

Comfort

The 4 Series does an admirable job of providing driving engagement without sacrificing comfort. You'll always feel like you're in a sporty car but won't be reminded of it every time you hit a bump in the road.

Seat comfort

The standard sport seats provide ample lateral support to keep you firmly planted when cornering. At the same time, there's adequate padding, and the well-shaped surfaces will keep you comfortable for hours on end.

Ride comfort

Most moderate road imperfections are smoothed as well as the competition. Even in the Sport modes, the ride never gets choppy or rough. It's a good blend of feeling connected to the road and not feeling every little rut.

Noise & vibration

4.5

Wind and road noise is reduced to near silence, even with the convertible, on rougher pavement and at highway speeds. It's so quiet that BMW thought it necessary to add engine noises through the interior speakers.

Climate control

The automatic climate control does an excellent job of either heating or cooling the cabin quickly. In typical BMW fashion, there's a separate temperature selector for the top vents as well.

Interior

The BMW 4 Series remains a pleasant middle ground to the more traditional Mercedes and starkly modern Audi interiors. The quality of materials and construction meet expectations for luxury coupes, even in the face of newer rivals.

Ease of use

3.5

There are a lot of buttons and knobs in the 4 Series, but they're grouped together and placed logically. If you've been in any BMW vehicle in the last decade, it should operate much the same.

Getting in/getting out

3.5

The long doors limit access in tight parking spots, as we expect from any coupe. The seat-belt presenters eliminate the awkward reach back once you're seated, though. Rear passengers will need to squeeze past a narrow opening, which is also typical for the class.

Driving position

The range of movement and numerous adjustments ensure that drivers of any size will be able to find their optimal position. Extendable thigh cushions are particularly nice for taller passengers.

Roominess

3.5

The 4 Series coupe is best described as snug but not confining. There's just enough room to be comfortable while still having a sporty wraparound feel. Average-size adults will barely fit in the backseats.

Visibility

3.5

Overall outward visibility is decent for the class. Narrow roof pillars make it easy to see through sharp turns, and the standard rearview camera takes any guesswork out of backing into a tight spot.

Quality

The quality materials used throughout the interior justify the 4 Series' price. The simulated leather in the standard 430i is very convincing and breathes just as well as the genuine article. The cabin feels durable and well assembled for a luxury coupe.

Utility

There's enough space for luggage and personal items to rate the 4 Series as average for the class.

Small-item storage

There aren't a lot of bins or pockets for your personal effects, and they aren't particularly big. But the typical items like smartphones, water bottles and coffee cups all have appropriate holders.

Cargo space

Trunk space in the coupe isn't as generous as in some competitors, but it will likely fit everything you need. The convertible's trunk is even smaller, but we were surprised that two carry-on bags will still fit (with the top up).

Technology

3.5

This 2018 refresh updates the already strong iDrive infotainment system, but it's far from being a major step forward. The available virtual instruments have a certain wow factor, but Audi's is more functionally useful.

Audio & navigation

3.5

BMW's iDrive system has a wealth of features, which means it can take some time to get familiar with all the controls and menus. After that it is intuitive, though some rivals are easier to acclimate to.

Smartphone integration

3.5

With Apple CarPlay available as an option, smartphone control is as good as any other system (as long as you have an iPhone). Otherwise, you will have quite a bit more scrolling and commands to operate many functions.

Driver aids

The advanced safety features are well tuned to catch your attention when needed without being so sensitive that it sends out false or premature alarms. You get the impression that they're there when you need them, and only then.

Morgan P,04/10/2018

This is a great car. It looks, smells, and performs very well. Getting behind the wheel, lowering the convertible top, and turning up some music, a smile cannot help but form on your face while you drive. When you need outstanding acceleration, it is there. The hard top makes for a very quiet ride when up. My wife and I love our 2018 BMW 440i convertible!

Bmw 440 the perfect car

2018 BMW 4 Series videos

[MUSIC PLAYING] CARLOS: We are sitting in a 2018 BMW 430i. That means this is a three series coupe. Now it's called the four series. And the 30i part means it has a turbo four cylinder with around 248 horsepower. We're going to have an acceleration run, or a few acceleration runs, in it to see how fast we can get it to 60 and the quarter mile. This is a manual, so it should be fairly straightforward and pretty traditional. But as a former three series coupe owner with a manual, I'm curious to see how this thing feels given that there's 20 years between my old car and this one. So as always, we'll start with our key-up acceleration. That means everything in the key-up settings, comfort, stability, control, traction control on. And let's just give it a try. 2000 RPM, that seems right. Nope, not enough. It seems like engine kind of runs out of steam as you get above 6500 RPM, but pulls strongly until that point. I like the red matching downshifts. It's all right. That's all right. I think we can cut some time off that. So we initially bogged on acceleration. That means engine wasn't delivering enough power to match the traction and revs immediately dropped down. You hear a little bit of tire chirping too. Doesn't like a super fast one, two gear change, so I'll have to be kind of lenient on that to not do too much mechanical abuse. But overall, it does what I expect. Power band feels really good between 4,000 and 6,000 RPM. I bet power peaks hiding in there. And the power delivery's strong right up in that area. Sounds all right for a turbo four too. they've taken a lot of the traditional turbocharge four cylinder sounds out, just has this hard-to-identify engine note. All right, let's get run number two a try. Sport plus, why not. And turn off stability control and traction control, because that's the secret to going fast. Also let's make sure we're lined up at the right spots. We have enough space to do out run. OK, let's try 2,500 RPM and see how that gets us off the line. Yeah, bogged again, need more RPM. Little bit of a delay on the gear change, there might be something in the drive line that is preventing me from shifting that fast. Cut 2/10 off acceleration to 60 at least. And I just realized, this thing has auto rev matching only when stability control is on weirdly. If you turn off stability control, your auto rev matching gets turned off as well. That's a really weird distinction to make, to have one system but not the other. That's probably not the way I would do it if I was responsible for those systems on this car. Because if you're driving this car and you're always expecting rev matching to be there, when it gets turned off, that's going to catch you by surprise like it did for me, a literal professional car testing person. That's official title too. So run number three. We're going to try 3,500 RPM because I bet we're going to be around there. Let's do it. Yeah. Little chirp in the second year, which is nice. That's actually a very helpful shift reminder. That's our V box doing that. Yep, and we just keep improving. I don't think we're going to get our 0 to 60 past that high five second mark. Power train does feel good. It's a little quicker than the numbers might lead you to believe. But it is a nice feeling drive, a nice feeling engine, even if it might get outrun by a v-6 Camry these days maybe. Probably would be pretty neck and neck, which is scary when you think about it. So acceleration runs in the four series with a six speed manual, the numbers themselves comparable with mid-size family sedans which is-- you'd expect a little bit more in terms of straight-line performance from a luxury coupe these days. Aside from the numbers themselves, the experience is very nice. And I think that's what people often conflate the numbers with is the experience. The shifter still feels really good. The clutch interplay and the pedal interaction between the shifter, gas pedal, clutch pedal is all very nice. Steering feels very good. Don't focus too much on numbers. This is still a pleasant experience. So think about that instead of the 0 to 60 time. [MUSIC PLAYING] CARLOS: If you like what you saw, keep it tuned right here.

2018 BMW 430i Track Test

Edmunds Senior Writer Carlos Lago runs a 2018 BMW 430i equipped with a six-speed manual transmission down the strip. The 4 Series' classical front-engine and rear-drive layout return a driving experience that has made BMWs so desirable to driving enthusiasts. This one has a turbocharged 2.0-liter four-cylinder under its hood that makes 248 horsepower and 258 pound-feet of torque. As we find out during acceleration and handling testing, the 430i may not generate the quickest numbers, but it sure feels good in the process.

More about the 2018 BMW 4 Series

BMW finds itself in a rare position of playing catch-up with Mercedes-Benz and Audi in the luxury sport coupe class. Recent redesigns to the Mercedes C-Class and Audi A5 and S5 models have raised the bar, but the 2018 BMW 4 Series remains competitive, buoyed by a few improvements to this year's model.

The 4 Series is available in either a coupe or convertible. The base 430i trim is powered by a 248-horsepower, turbocharged 2.0-liter four-cylinder engine while the 440i gets a 326-hp 3.0-liter turbocharged six-cylinder. A standard eight-speed automatic transmission sends power to the rear wheels, and BMW's xDrive all-wheel-drive system is offered on all models. A six-speed manual transmission is only available on the coupe.

Standard 430i features highlights include 18-inch wheels, LED headlights, a sunroof, auto-dimming mirrors, selectable drive modes, BMW's Assist eCall emergency telematics, synthetic leather upholstery, BMW's iDrive infotainment system and a rearview camera. The 440i adds leather upholstery, keyless entry and ignition, and a premium 16-speaker Harman Kardon surround-sound system with satellite radio.

Notable options include various sporty exterior touches, adaptive headlights, automatic high beams, an M Sport or adaptive suspension, an automated parking system, a head-up display, a navigation system, heated front seats, a power rear sunshade, a surround-view camera system, Apple CarPlay and a wireless charging pad. On the safety front, front and rear parking sensors, blind-spot monitoring, frontal collision warning and mitigation, a lane departure warning system and adaptive cruise control are also available.

In terms of price, the 2018 BMW 4 Series is in lockstep with the Mercedes C-Class and Audi A5 or S5 if you outfit the vehicles similarly. The newer Mercedes trends a bit more to the traditional luxury side while the Audi pushes modernity and technology to new levels. In many ways the BMW finds a pleasant middle ground, and despite its age handicap, is still worth serious consideration.

Should I lease or buy a 2018 BMW 4 Series?

Is it better to lease or buy a car? Ask most people and they'll probably tell you that car buying is the way to go. And from a financial perspective, it's true, provided you're willing to make higher monthly payments, pay off the loan in full and keep the car for a few years. Leasing, on the other hand, can be a less expensive option on a month-to-month basis. It's also good if you're someone who likes to drive a new car every three years or so.
