2017 BMW 4-Series Review

By Zach Doell June 20, 2017

The 2017 BMW 4 Series lays the blueprint for the ideal luxury small car. It’s fun to drive, big on power, heavy on refinement, and available with tons of technology. 

Is the BMW 4 Series a Good Car?

The sleek BMW 4 Series promises much with its elegant physique, but this well-rounded BMW delivers on nearly all of its claims. The 4 Series is a driver’s car, and its athletic handling backs that up. The 4 Series can carve corners with sports car-like precision, but it cruises comfortably as well, especially when equipped with its optional adaptive suspension. Pop the hood and you’ll find one of three punchy turbocharged engines. The standard four- and six-cylinder engines (430i and 440i models) offer a great balance of get-up-and-go power with good fuel economy. The no-nonsense BMW M4 turns the 4 Series into one serious performer.

It’s not all about the thrills, though. The 2017 4 Series is practical, too. It earns a high score for predicted reliability and offers some of the best cargo space in its class. Lift the rear hatchback of the 4 Series Gran Coupe model and you’ll find a vast 45.9 cubic feet of cargo space with the rear seats folded. The 4 Series offers loads of high-tech convenience and safety features as well, including automatic self-parking. If there is a downside, it’s that the 4 Series coupe and convertible models don’t offer much in the way of rear-seat space. However, that is fairly typical of two-door luxury small cars.

Should I Buy the BMW 4 Series?

The 2017 BMW 4 Series is an excellent pick if you’re shopping for a sporty luxury car. Its only real hang-up is its price. The 4 Series is available in three body styles: coupe, convertible, and four-door Gran Coupe sedan. The coupe and convertible start at $42,150 and $50,300, respectively. That puts it on par with the 2017 Mercedes-Benz C-Class coupe and convertible, though both of those models offer a bit more standard equipment, including a rearview camera, forward collision warning, and automatic emergency braking. Even if you’re not pinching pennies, the highly rated C-Class is a great pick.

On the other hand, the 4 Series Gran Coupe costs $41,950. If you’re simply looking for a sporty four-door luxury car, you’ll want to check out the 2017 BMW 3 Series sedan. The 3 Series offers many of the same features as the 4 Series and can match its performance, but prices start at a much lower $33,450. Looking to maximize your savings? The 3 Series is the better choice.

All things considered, the BMW 4 Series is a top competitor in the luxury small car class. As long as it fits your budget, it should be a top consideration on your shopping list.

The 430i coupe and convertible models cost $42,150 and $50,300, respectively. Standard features include a 248-horsepower engine, a 6.5-inch iDrive infotainment screen, Bluetooth, and leatherette upholstery. Popular options include adaptive cruise control ($1,200), Apple CarPlay connectivity ($300), automatic self-parking ($500), and a rearview camera and parking sensors ($950).

The BMW 440i adds a 320-horsepower six-cylinder engine, and pricing starts at just over $48,000 for coupe and Gran Coupe models ($57,300 for convertibles). The top BMW M4 trim level is available in coupe ($66,200) and convertible ($74,700) body styles only. It packs a 425-horsepower engine.

BMW 4 Series Versus the Competition

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

Automotive rivalries don’t get much more heated – or evenly matched – than the battle between the BMW 4 Series and the Mercedes-Benz C-Class. These competitors are both available in coupe and convertible body styles, and they trade blow-for-blow, offering comparable starting prices, highly refined and well-equipped interiors, and similarly robust engine performance. The 4 Series edges a slight lead thanks to its great predicted reliability score, and that lead becomes larger when the roads get twisty. Both of these German cruisers are competent at slicing around bends, but the 4 Series is the sharper of the pair.

If you’re after standard features, the C-Class is a bit more enticing. You’ll find forward collision warning, automatic emergency braking, and a rearview camera as standard equipment in the base Mercedes C300 coupe ($42,650). All of those features are optional in the 4 Series. Add all three to the base 430i coupe, and you’ll pay $4,100 more than the C-Class. Granted, that value proposition quickly disappears once you journey up the C-Class’ trim levels. Things get pricey, and fast. At the end of the day, both the 4 Series and the C-Class are great picks, but it’s the BMW 4 Series that delivers more smiles per hour.

Which Is Better: BMW 4 Series or Audi A5?

The Audi A5 once occupied the same territory that the BMW 4 Series now owns – the comfortable yet sporty cruiser. Like the 4 Series, the A5 is available as a two-door coupe and convertible, and you’ll find a well-built cabin with high-quality materials. But unlike the 4 Series, it’s become rather long in the tooth.

You’ll find fewer driver convenience features in the A5, as well as fewer safety features. The A5 offers just blind spot monitoring and parking sensors. By comparison, the 4 Series can park itself, and it offers technology like adaptive cruise control and automatic emergency braking. Adding insult to injury, the A5’s four-cylinder engine doesn’t feel nearly as lively on the road. An all-new Audi A5 is set to arrive for 2018, and its appearance couldn’t come sooner. Until then, the 4 Series’ lead remains safe. If you’ve still got your heart set on a new Audi, the fully redesigned 2017 A4 sedan is a better pick than the A5, thanks to its superior convenience and active safety features.

4 Series Interior

How Many People Does the 4 Series Seat?

The 2017 BMW 4 Series coupe and convertible models seat four, while the 4 Series Gran Coupe sedan seats five. Slide into the front seats and you’ll find them mounted low to the floor, providing a sporty feel as well as good head- and legroom. The seats themselves are very comfortable and even feature power-adjustable side bolsters, allowing you to tailor your level of lateral support – tight for carving curvy roads, loose for cruising down the highway.

The 4 Series’ rear seats are comfy as well, but seating space in the back is much more confined due to the BMW’s sloping roofline, especially in coupe and convertible models. This is pretty typical of luxury two-doors. The four-door Gran Coupe isn’t as pinched, though legroom is still a rather slim 33.7 inches. For a bit more space, opt for the 4 Series’ sibling – the BMW 3 Series sedan – or the Mercedes-Benz C-Class sedan, which both offer nearly 2 inches more rear legroom.

4 Series and Car Seats

The 2017 4 Series coupe and convertible feature full LATCH child-seat equipment in each of their rear seats. This includes a pair of lower anchors mounted between the seat cushion and seatback, and a single upper tether anchor mounted on the rear window shelf. The 4 Series Gran Coupe provides full LATCH equipment at each of its outboard rear seats, while the middle seat features an upper tether anchor only. Both configurations are suitable for attaching two child seats.

4 Series Interior Quality

There’s nothing overtly flashy about the 2017 4 Series’ interior, and that’s a very good thing. The 4 Series’ cabin has a clean and understated look to it, and it features an array of soft-touch plastics as well as wood veneers. The dashboard angles elegantly toward the driver’s seat, providing easy access to the audio and climate controls. All in all, it’s a very nice place to be.

4 Series Cargo Space

The BMW 4 Series is a leader when it comes to driving thrills, but it’s also rather practical. The 4 Series coupe offers a comparatively spacious 15.7 cubic feet of trunk space, which is about 5 cubic feet more than you’ll find in the Mercedes-Benz C-Class coupe, Lexus RC, or Cadillac ATS coupe. The 4 Series convertible offers an impressive 13.1 cubic feet of trunk space.

It’s the 4 Series Gran Coupe that takes the cake, though. Despite its sedan appearance, the Gran Coupe features a rear hatchback, which opens up to reveal a wide loading space and 17 cubic feet of room. Fold the rear seats down, and this space expands to 45.9 cubic feet. That’s enough room to stow a pair of bicycles, transport a few dining room chairs, or load larger items like a bookcase.

4 Series Infotainment, Bluetooth, and Navigation

The 2017 BMW 4 Series delights with its large array of tech features. Standard features include a 6.5-inch display screen with BMW’s iDrive infotainment system, a rotary controller, HD Radio, Bluetooth, USB inputs, and a nine-speaker stereo. While it may take some time to get acquainted with, the iDrive system is user-friendly and responds quickly to inputs.

Admittedly, the best features are optional extras, which can be pricey. Options include a larger iDrive display screen with satellite navigation and a touchpad controller, a head-up display that projects information onto the windshield, a 16-speaker Harman Kardon sound system, a rearview camera, wireless device charging, and support for Apple CarPlay.

Attached at the hip to your iPhone? Apple CarPlay merges its features and functions with iDrive, making it even easier to access your favorite music or phone a friend using the infotainment system. A few rivals support Apple CarPlay as well, including the Audi A4 and Cadillac ATS.

4 Series Performance

4 Series Engine: A Boost in Power

The biggest changes for the 2017 4 Series happen under the hood. BMW replaces its turbocharged four- and six-cylinder engines with two new versions, both of which pack a bit more power. The 2017 430i – previously known as the 428i – receives a 2.0-liter four-cylinder with 248 horsepower. The 440i (née 435i) is upgraded with a 3.0-liter six-cylinder, which produces 320 horsepower.

As in previous models, the 2.0-liter engine delivers plenty of punch that can zip the 4 Series to 60 mph in around 5.5 to 6 seconds, depending on model. That’s more punch than most drivers will need, but if you’re looking for more, the 4 Series’ smooth six-cylinder is the answer. Both engines can be paired with an eight-speed automatic or six-speed manual transmission, and both are available with rear- or all-wheel drive (“xDrive,” in BMW lingo). That said, only coupe models are available with the manual.

The six-speed manual earns good marks for its crisp, precise shift action. The eight-speed automatic is a worthy pick as well. It shifts promptly on its own, or you can click through each gear using the 4 Series’ standard shift paddles.

Looking for sizzling performance? The BMW M4 coupe and convertible soldier on with a twin-turbo 3.0-liter six-cylinder, which serves up 425 horsepower. A six-speed manual is standard and a seven-speed dual-clutch automatic transmission is optional. A Competition package is optional as well, and it can raise this figure to 444 horsepower. Need even more? You’ll have to look to the Mercedes-AMG C63 S (503 horsepower) or Alfa Romeo Giulia Quadrifoglio (505 horsepower) for more kick.

4 Series Gas Mileage: A Light Appetite

The 2017 BMW 4 Series matches its powerful engine performance with good fuel efficiency. The BMW 430i coupe, convertible, and Gran Coupe sedan can all achieve 23 mpg in the city and 34 mpg on the highway when equipped with the eight-speed automatic and rear-wheel drive. The 440i coupe and Gran Coupe can manage 21 mpg in the city and 32 on the highway, while the 440i convertible earns a lower 21/29 mpg city/highway rating. Adding all-wheel drive doesn’t drop these ratings very much – a point or two at most. Going with the six-speed manual takes a larger two- to three-point chunk.

These ratings are great for the luxury small car class, but a few rivals can do better. The Audi A4 gets 27/37 mpg city/highway and the Mercedes-Benz C300 manages 24/34 mpg. For maximum efficiency in the BMW family, look for the diesel-powered BMW 328d sedan, which can hit 31/43 mpg.

The high-performance BMW M4 is thirstier. The M4 coupe and convertible can achieve 17/26 mpg when equipped with the six-speed manual. The seven-speed dual-clutch automatic delivers 17/24 mpg.

4 Series Ride and Handling: A Good Sport

The BMW 4 Series strikes a good balance between its sports car ambitions and luxury car refinement. The 4 Series corners with sharp athletic precision, and it feels planted when the roads get twisty. Its ride is firm, but not punishing. For those looking for a softer ride, the 4 Series offers an optional adaptive suspension. This setup can electronically adjust the car’s shocks, allowing it to feel sporty and composed for spirited driving, but also plush and laid-back when cruising on the highway. It’s a $700 option worth adding.

If the 4 Series does pose one annoyance, it stems from its fuel-saving stop-start system, which automatically turns off the engine when at a full stop (think stop-and-go traffic). The engine kicks back on as soon as you release the brake pedal, but it’s not a particularly smooth operation and it can become aggravating on long commutes. That said, it can be disabled.

4 Series Reliability

Is the BMW 4 Series Reliable?

Yes, the 2017 BMW 4 Series earns a great predicted reliability score of four out of five points, according to J.D. Power and Associates.

This score tops the 2017 Cadillac ATS and Infiniti Q60, which each receive three points. It also bests the Audi A5 which scores 3.5 points, though the Mercedes-Benz C-Class gets a score of four. The Lexus RC coupe scores higher, at 4.5 points.

BMW 4 Series Warranty

The 2017 BMW 4 Series is covered by a four-year/50,000-mile new-car limited warranty, as well as four-year/unlimited-mileage roadside assistance coverage.

This warranty length is fairly typical among luxury automakers; however, some companies provide longer coverage. The Cadillac ATS is additionally covered by a six-year/70,000-mile powertrain warranty and matching roadside assistance coverage.

4 Series Safety

4 Series Crash Test Results

We are unable to provide crash test safety scoring for the 2017 BMW 4 Series. Neither the National Highway Traffic Safety Administration nor the Insurance Institute for Highway Safety have published crash test results for the 2017 model year.

4 Series Safety Features

The 2017 BMW 4 Series is available with a large array of high-tech safety features, many of which are optional extras in all trim levels. Shoppers can add a rearview camera, front and rear parking sensors, blind spot monitoring, a 360-degree-view camera, speed limit information, adaptive pivoting headlights, automatic self-parking (Parking Assistant), adaptive cruise control, and BMW’s Active Driving Assistant.

Active Driving Assistant includes lane departure warning, forward collision warning, automatic emergency braking, and pedestrian detection. If the possibility of a collision looks high, the system can notify the driver and apply the brakes, helping to avoid or limit the severity of an accident.

A number of competitors offer a similarly packed suite of active safety features. Standouts include the Mercedes-Benz C-Class, which features forward collision warning and automatic emergency braking as standard equipment. The Audi A5 is at the other end of the spectrum, offering relatively few driver convenience features (just parking sensors and blind spot monitoring).

Which BMW 4 Series Is Right for Me?

Unless you’re tempted by high horsepower, the base model BMW 430i coupe is likely all the 4 Series you’ll ever need. This sleek coupe starts at just $42,150 and comes outfitted with a 248-horsepower four-cylinder engine. You can opt for either a six-speed manual transmission or an eight-speed automatic. Rear-wheel drive is standard and all-wheel drive is a $2,000 option.

The 430i coupe comes relatively well-equipped from the start, including a 6.5-inch iDrive display screen and infotainment system as standard. Most of its best equipment is available through pricey option packages. The trade-off is that many of these packages are available a la carte, so you can add the stuff you want. By comparison, some rivals require that you buy a higher, pricier trim level to access these optional features.

For an in-depth look at each trim level and its popular options, check out the sections below.

BMW 430i

The least expensive 4 Series is the base BMW 430i model, which costs $41,950 as a Gran Coupe sedan, $42,150 as a coupe, and $50,300 as a convertible. Standard equipment for each includes a 6.5-inch iDrive infotainment screen, a USB port, a CD player, HD Radio, Bluetooth, nine speakers, automatic climate control, ambient lighting, leatherette upholstery, a leather-wrapped steering wheel, power front seats, split-folding rear seats, an alarm system, a universal garage door opener, a moonroof, and rain-sensing wipers. Gran Coupe sedans also add a power rear tailgate.

All BMW 430i models are powered by a 248-horsepower four-cylinder engine. An eight-speed automatic transmission with shift paddles is standard, as is rear-wheel drive. BMW’s xDrive all-wheel drive costs an extra $2,000. A six-speed manual transmission is a no-cost option for rear-wheel-drive coupes only.

Additional stand-alone options include adaptive cruise control ($1,200), automatic self-parking ($500), Apple CarPlay compatibility ($300), and the adaptive M suspension ($700). A number of option packages are also available, including a Cold Weather package (heated front seats and steering wheel), a $950 Driver Assistance package (rearview camera and parking sensors), and a $2,750 Technology package (navigation, head-up display, real-time traffic updates, and remote vehicle access via app). A $1,700 Driver Assistance Plus package adds blind spot monitoring, a 360-degree camera, lane departure warning, forward collision warning, automatic emergency braking, and pedestrian detection.

BMW 440i

The BMW 440i trim adds proximity keyless entry, front-seat lumbar adjustments, satellite radio, and a Harman Kardon surround sound system. Convertibles also add a wind deflector and leather upholstery. Pricing is as follows: $48,300 (Gran Coupe sedan), $48,500 (coupe), and $57,300 (convertible).

All BMW 440i models are powered by a 320-horsepower six-cylinder engine. An eight-speed automatic and rear-wheel drive are standard. All-wheel drive is an extra $2,000. A six-speed manual transmission is a no-cost option for coupes only (rear- and all-wheel drive).


The racy BMW M4 is available in coupe ($66,200) and convertible ($74,700) models only, and it packs a 425-horsepower six-cylinder engine. A six-speed manual transmission and rear-wheel drive are standard. A seven-speed dual-clutch automatic is a $2,900 option.

Standard equipment includes leather upholstery, heated front seats, navigation, real-time traffic updates, carbon fiber interior trim, the adaptive M suspension, and the M Drive vehicle preferences menu (for setting suspension, traction control,  and other performance presets). A $4,750 Competition package adds new steering, stability control, differential, and suspension settings, as well as a bump up to 444 horsepower. Carbon ceramic brakes are a pricey $8,150 option.

The Final Call

The 2017 BMW 4 Series fulfills most of the requirements that make a great luxury small car. The 4 Series corners with impeccable poise, rides smoothly over bumpy city streets, cruises comfortably on the highway, and delivers zesty performance with a prod of the gas pedal. Step inside, and you’ll find an upscale cabin that’s filled with high-tech gadgets as well.

For maximum savings, go with the BMW 3 Series sedan. It offers many of the same features and can match the 4 Series in performance, but it costs a little less. Otherwise, the 4 Series is the top pick in this class, and it’s worthy of the top spot on your shopping list. Don’t just take our word for it. Check out comments from some of the reviews that drive our rankings and analysis.

  • "The 2017 BMW 4 Series should be near the top of your list if you're in the market for a luxury sport coupe or convertible. Whether you're enjoying its blend of features and refinement or putting its smooth optional engine to the test, you'll probably come away with a positive impression. It might run in a crowded class, but the 4 Series is easily one of the best." -- Edmunds
  • "The BMW 4 Series is in reality a 3 Series coupe, and if you're looking for the driving dynamics of that sedan but in a sleeker package, you've found your ride. As for the 4-door Gran Coupe? It's as practical as it is beautiful thanks to its spacious hatch." -- Kelley Blue Book
