Is the BMW 4 Series a Good Car?

Yes, the BMW 4 Series is a good luxury small car. It features razor-sharp handling and powerful engine choices, and the high-performance BMW M4 takes performance to the next level. Inside, cabin quality hits the mark for a luxury vehicle, and this BMW boasts a long list of standard infotainment and active safety features.

The 4 Series comes in coupe, convertible, and sedan body styles, which each have an excellent amount of cargo room for the class. However, the back seat is barely usable in the two-door versions, and space isn’t that great even in the larger Gran Coupe sedan. 

Should I Buy the BMW 4 Series?

The 4 Series is certainly worth your consideration if you’re looking for a fun and upscale small car, but at around $45,000, its lofty starting price may put off many shoppers. It’s worth checking out a closely ranked rival like the Mercedes-Benz C-Class or a segment leader such as the Audi A5 before you make your decision.

Should I Buy a New or Used BMW 4 Series?

For 2020, the 4 Series gains rain-sensing windshield wipers and the BMW Active Driving Assistant suite of safety features as standard equipment. Every model now comes with lane departure warning, forward collision warning, pedestrian detection, and automatic emergency braking. All of these features were previously optional.

The 2020 BMW 4 Series is part of a generation that dates back to the 2014 model year. You can likely save thousands of dollars with a used 4 Series, just know that some models don't have those driver assistance features. Older models are usually less expensive, but there are some year-to-year changes to consider.

The 2019 4 Series gained standard Apple CarPlay, navigation, and parking sensors. For the 2018 model year, BMW refreshed the 4 Series’ appearance, enhanced the suspension tuning, and introduced available pedestrian detection. For 2017, some trims were renamed and given a horsepower boost, and wireless device charging and a Wi-Fi hot spot became available. The Gran Coupe body style and the high-performance M4 model joined the 4 Series lineup for 2015.

How Much Does the BMW 4 Series Cost?

The BMW 4 Series has one of the highest base prices in the luxury small car class. The 2020 4 Series Gran Coupe, which is actually a four-door model, starts at $44,750. The two-door coupe starts at $44,950, and the base price of the convertible model is $53,100.

The base 430i trims of each body style come with a four-cylinder engine, while 440i models come with a six-cylinder engine and cost several thousand dollars more. Rear-wheel drive is standard, and BMW's xDrive all-wheel-drive system is optional for $2,000. The high-performance BMW M4 coupe starts at $69,150 and the M4 convertible starts at $77,650.

BMW 4 Series Versus the Competition

Which Is Better: BMW 4 Series or Audi A5?

The well-rounded Audi A5 ranks high in the luxury small car class. Each model is available as a coupe, convertible, and four-door sportback; each has a high price for the class; and each has a dedicated performance model (the RS 5 and M4, respectively).

The Audi has one of the nicest interiors in the class, and all of its tech features are user-friendly. It also comes standard with Android Auto and Apple CarPlay, while the 4 Series only has Apple CarPlay and requires a subscription to keep it past the initial one-year term. The A5’s back seat feels a little roomier, and it has several more feet of cargo space behind the second row of the Sportback model. In other body styles, the 4 Series has more trunk space.

You’ll get slightly better overall performance with the A5, owing to zippy handling and smooth, refined powertrains. The Audi A5 is the better choice in this matchup.

Which Is Better: BMW 4 Series or Mercedes-Benz C-Class?

The 4 Series and the Mercedes-Benz C-Class sit close in the top third of our class rankings. These two cars will likely appeal to different sets of buyers. The BMW prioritizes dialed-in handling and raucous engine power, while the C-Class pampers you with a plush ride and sumptuous interior quality. However, Mercedes offers AMG versions of the C-Class that boast up to 503 horsepower.

You can get both of these cars as two-door coupes, four-door sedans, and two-door convertibles. The starting price of the C-Class sedan is several thousand dollars less than that of the base 4 Series. However, the C-Class has trickier infotainment controls and a lower predicted reliability rating than the BMW. You really can’t go wrong with either of these cars so your choice will come to what you favor more: luxury or sportiness.

4 Series Interior

How Many People Does the 4 Series Seat?

The standard BMW 4 Series Gran Coupe – actually a four-door car – seats five people. It’s also the roomiest of the lineup, with a back seat that’s easy to enter. However, the sloping roof means that taller passengers might feel a little short on headroom.

In 4 Series coupe and convertible models, there's seating for four, and the second rows feel confined.

The front seats in all 4 Series body styles are comfortable and supportive, with a solid driving position and unhindered all-around outward visibility. Power-adjustable front seats are standard, and you can opt for heated front and rear seats.

4 Series and Child Car Seats

The 4 Series has two complete sets of rear LATCH connectors. Gran Coupe models have a tether anchor for the rear middle seat. The lower anchors are set deeply in the seat and they’re hard to access. That’s despite being located behind plastic flaps in a dedicated cut-out section. The tether anchors in the Gran Coupe are on the back of the rear seats, about halfway down. Those connections are easy to find.

4 Series Interior Quality

The 4 Series has the opulent cabin and upscale design you’d expect of a roughly-$45,000 car. Most surfaces are soft to the touch, and you can spend more money to get extra leather covering parts of the dashboard and door panels.

SensaTec synthetic leather upholstery is standard, and you’ll have to pay extra for the real thing. You might also notice some hard plastics in inconspicuous areas, such as the bottom of the center console and transmission tunnel.

4 Series Cargo Space

In any body style, the 4 Series has a great amount of cargo room. The hatchback Gran Coupe serves up 17 cubic feet of space with the rear seats upright, and you can fold them down to open up 45.9 cubic feet. A standard power liftgate and a wide cargo opening increase the utility of this BMW even more.

The 4 Series coupe has 15.7 cubic feet of trunk space, which is excellent for a luxury small car. Convertible models have 13.1 cubic feet.

4 Series Infotainment, Bluetooth, and Navigation

BMW’s acclaimed iDrive infotainment system is standard throughout the 4 Series lineup. You control the system through a sharp 8.8-inch touch screen or via a rotary knob on the center console. This interface is pretty straightforward once you get past an initial learning curve. It’s easy to navigate through on-screen menus as well as use physical knobs to adjust climate and audio settings.

The 4 Series also comes standard with Apple CarPlay. The good news is that you can connect your phone wirelessly, but the bad news is that BMW only gives you an initial one-year trial to CarPlay. After that, you’ll pay around $80 for an annual subscription. That pricing model is in stark contrast to the rest of the industry, with many other brands (including nonluxury marques) offering standard unlimited Apple CarPlay. BMW does not offer the 4 Series with Android Auto.

4 Series Performance

4 Series Engine: 3 Solid Choices

BMW names 4 Series trims after what’s under the hood of each model. The standard BMW 430i features a 248-horsepower turbocharged four-cylinder engine. This peppy powertrain gets you moving easily, though it might sound or feel a little unrefined. The BMW 440i and its 320-horsepower turbocharged inline-six engine is much more satisfying. There’s ample power as soon as you hit the gas pedal, and this model also has an engaging sports-car-like exhaust note.

The 430i and 440i come standard with an eight-speed automatic transmission, which rattles off sharp, timely shifts. The 4 Series also keeps things old-school with an optional six-speed manual transmission, available for no extra charge as a replacement to the standard automatic in coupe models.

The range-topping BMW M4 is the high-performance variant available in coupe and convertible forms. It's powered by a twin-turbocharged 425-horsepower engine. The optional Competition package ups the output to 444 horsepower. The twin-turbo M4 comes standard with the six-speed manual, and a silky-smooth seven-speed dual clutch automatic is optional.

4 Series Gas Mileage: Just Fine

At an EPA-estimated 23 mpg in the city and 34 mpg on the highway, the fuel economy for the standard rear-wheel-drive 2020 430i is about average for the class. The best gas mileage from all-wheel-drive models is 22/32 mpg city/highway.

The BMW 440i gets up to 22/30 mpg. Fuel economy is a little lower if you opt for the manual transmission in the 4 Series coupe. The 2020 M4 Coupe gets up to 18/25 mpg.

4 Series Ride and Handling: Bold  

The 4 Series shares the engaging driving dynamics and lithe handling found in many of the brand’s other sporty luxury cars. Though you might wish there was more feedback from the road, steering is generally sharp and responsive. The car’s low and wide stance helps it feel confident and controlled around corners. An optional Track Handling package enhances agility with upgraded variable sport steering, an adaptive M suspension, M Sport brakes, and non-run-flat performance tires.

There are four adjustable driving modes to choose from: Comfort, Eco Pro, Sport, and Sport+. Comfort delivers the softest and most forgiving ride – no surprise there – while Sport ups responsiveness a bit without sacrificing too much comfort. Ride quality in Sport+ mode can feel a little too harsh.

Which BMW 4 Series Model Is Right for Me?

Like most BMW models, you can get the 4 Series in many different configurations. Body styles include two-door coupe, the four-door Gran Coupe, and convertible. The Gran Coupe is the standard style, and those models are the least expensive. Coupe versions are about $200 more, while the convertibles are several thousand dollars more.

Once you pick a body type, you choose a trim. The 4 Series is available as the four-cylinder 430i and the six-cylinder 440i. Rear-wheel drive is standard and all-wheel drive is a $2,000 option. An eight-speed automatic transmission also comes standard, while you can opt for a six-speed manual in coupe models for no extra charge. The BMW M4 is rear-wheel-drive-only with a standard manual transmission. A seven-speed dual-clutch automatic transmission is optional in that model.

BMW 430i

The 2020 BMW 430i Gran Coupe starts at $44,750. Standard features include synthetic leather upholstery, 10-way power-adjustable front sport seats, a leather-wrapped steering wheel, dual-zone automatic climate control, a moonroof, a power liftgate, a universal garage door opener, and proximity keyless entry. The iDrive infotainment system features an 8.8-inch touch screen, navigation, voice recognition, Apple CarPlay, HD Radio, satellite radio, a nine-speaker stereo, a USB port, and Bluetooth. Standard driver assistance features include lane departure warning, forward collision warning, pedestrian detection, automatic emergency braking, a rearview camera, front and rear parking sensors, and rain-sensing windshield wipers.

From here, you can upgrade the car with the $3,700 M Sport Design, which adds enhanced exterior styling, an M Sport Suspension, a sport steering wheel, blind spot monitoring, and heated front seats.

If you eschew that, there are other less-expensive option packages. The Convenience package costs $1,100 and adds blind spot monitoring, heated front seats, and four-way front-seat lumbar adjustment. The $2,550 Executive package includes automatic high-beam headlights, a surround-view parking camera system, automatic parking assist, and adaptive headlights.

The Track Handling package costs $1,700 and adds variable sport steering, an adaptive M suspension, M Sport brakes, and non-run-flat performance tires.

BMW 440i

The BMW 440i Gran Coupe has an MSRP of $51,150, and it comes standard with the Harman Kardon stereo. Most of the options from the 430i carry over, though a couple of the packages are less expensive, including the Convenience bundle ($850 in this trim).  

BMW M4

The BMW M4 is available as a coupe ($69,150) and a convertible ($77,650). A six-speed manual transmission is standard, while a seven-speed dual-clutch automatic is optional for $2,900. For $4,750, the Competition Package bumps up horsepower to 444 and upgrades the steering, differential, and suspension settings. It also comes with enhanced appearance features.

The Final Call

The BMW 4 Series is as fun to drive as you’d expect, and it has the upscale interior to back up its luxury claims. If you can open your wallet wide enough and are willing to overlook a shortage of interior space, this BMW makes a compelling case in the luxury small car class.

Don’t just take our word for it. Check out comments from some of the reviews that drive our rankings and analysis.

  • "You shouldn't confuse a luxury coupe, even one such as the BMW 4 Series, with a sports car. But if you can manage expectations and keep the pricey options under control, this BMW offers a satisfying balance of comfort, capability and technology." -- Edmunds
  • If you want the well-regarded driving dynamics of [the 3 Series] in a sleeker package or with a retractable-hardtop roof, the 4 Series is it. As for the 4-door Gran Coupe, it blends fine handling, sharp looks and strong practicality. … Impressive as the 4 Series lineup is, these luxury-performance coupes aren't the only game in town. You may prefer the tech advances of the Mercedes-Benz C-Class coupe and new Audi A5." -- Kelley Blue Book
  • "Both engines are phenomenal. The handling is excellent. If your lifestyle and budget can incorporate a premium 4-door with a hatchback and restricted rear-passenger space, then the operative word here is 'bingo.'" -- Autotrader (2016)
