2018 BMW 4 Series Coupe Review

by Adam Lynton

Back in 2013, the BMW 4 Series was tipped to replace the coupe variant of the 3 Series and, since then, has become a vehicle that encompasses the performance and refinement expected of a sports coupe. Actively striving to remain in the top ranks of this segment, the 2018 BMW 4 Series faces stiff competition from the redesigned Audi A5, Lexus RC, and the Mercedes-Benz C-Class Coupe. Available in two models, the 430i and the 440i, the 4 Series has rear-wheel-drive as standard but can be had in the all-wheel xDrive variations too. The base model 430i is powered by a 2.0-liter turbo four-cylinder engine paired to an eight-speed automatic transmission which makes 248 horsepower and 258 lb-ft of torque. The top-end 440i has a 3.0-liter six-cylinder engine under the hood, which also works with an eight-speed automatic and delivers 320 hp and 330 lb-ft. Uniquely, the 4 Series still offers a six-speed manual transmission as an optional extra for the driver who likes to be a little more hands-on. With stiff competition in this segment, one has to wonder whether the 4 Series Coupe will remain in the upper echelons of its class.

2018 BMW 4 Series Coupe Changes: What’s the difference vs 2017 4 Series Coupe?

For 2018 the 4 Series gets a minor facelift, with new front and rear LED lights, as well as changes to the front bumper, intakes and the rear apron. New wheel designs were added for this model year, and two fresh colors are included to the exterior paint options list. On the inside, updates to the navigation system, as well as new upholstery colors and accents are notable. Mechanically, the 2018 4 Series also gets a stiffer suspension for more responsive handling.

Pros and Cons

  • Powerful engine performance
  • Classy interior
  • Decent space for a coupe
  • Agile handling
  • Responsive transmission
  • Apple Carplay is an expensive optional extra
  • Necessary driver aids must be purchased additionally
  • Android Auto is not available

4 Series Coupe Exterior

While it now carries its own name, the 4 Series looks distinctly like a coupe 3 Series, but with a little more added spice. Rolling out on a selection of standard 18-inch light-alloy wheels, the 4 Series has the option of upgrading to double-spoke 19-inch wheels in any one of three styles. The exterior is characterized by the trademark kidney grille, flanked by upswept LED lights and features an updated bumper for this year's model. Classic coupe looks dictate the sleek, sloping roofline which culminates into a contemporary trunk area complete with LED taillight clusters.

Dimensions

The new 4 Series has a length of 182.6 inches, set on a wheelbase of 110.6 inches. Standing 54.2 inches tall in standard rear-wheel-drive configuration, the xDrive variant is a fraction taller at 54.8 inches. Marginally smaller in dimensions to the Mercedes C-Class Coupe, the 4 Series is 71.9 inches wide and has a range-standard 5.1 inches of ground clearance. Curb weights vary across trims and drivetrain options, with the rear-wheel-drive base model 430i weighing in a 3,574 lbs, while the 440i xDrive all-wheel-drive tips the scales at 3,827 lbs. The Audi A5 has very similar dimensions, while the Mercedes-Benz C-Class Coupe weighs slightly more.

Exterior Colors

There's a wide selection of colors to choose from when customizing the 4 Series. Alpine White and Jet Black are regular non-metallics available at no extra charge. Sunset Orange and Snapper Rocks Blue Metallic are new Metallic hues added at a $550 premium, and add some sporty appeal to the remainder of the palette that carries over from the previous year. This includes Black Sapphire, Melbourne Red, Glacier Silver, Imperial Blue, Sparkling Brown, Mineral Grey, and Mineral White. Estoril Blue Metallic is available exclusively with the M Sport Package. For the top-tier trim, BMW Individual colors are also available at $1,950 and expand the palette with elite options such as Smoked Topaz, Tanzanite Blue, Citrin Black, and Champagne Quartz.

4 Series Coupe Performance

The 2018 4 Series comprises two models, namely the 430i or the 440i and both are available in either rear-wheel-drive or all-wheel-drive guise. The 430i is powered by a twin-turbo 2.0-liter, four-cylinder engine that produces 248 hp and 258 lb-ft. The more powerful variant is the 440i; powered by a 3.0-liter twin-turbo six-cylinder, it's naturally quicker, with outputs of 320 hp and 330 lb-ft sending it from 0-60 mph in 4.6 seconds in xDrive guise, with the RWD model two-tenths behind. Regardless of drivetrain, the 430i manages the sprint in 5.5 seconds. If optioned with the manual transmission, the 4 Series needs an additional second per trim to hit the 60 mph mark. All models are governed to 130 mph but can reach 155mph if the M-Sport or Track Handling Packages are added.

But where the 3 Series Coupe was once the definitive driver's tool, BMW has now lost its edge. "Sheer Driving Pleasure" has given way to compromise in an effort to sell more cars, and the BMW coupe is now no longer the sharpest knife in the drawer.

Engine and Transmission

Both available models feature strong engine options, namely a 2.0-liter inline-four on the 430i that kicks out 248 hp and 258 lb-ft, and the bigger 3.0-liter inline-six on the 440i, where outputs hit 320 hp and 330 lb-ft. While both powertrains are paired to an eight-speed automatic transmission, a six-speed manual option is also available, making BMW one of only a few manufacturers to offer one at this level.

The base 430i is responsive and doesn't feel sluggish, thanks to the speedy shifts of the eight-speed auto. While the performance is adequate, the sound of the 2.0-liter engine doesn't quite do the car justice with some rough-around-the-edges vocalization at times. The 440i, on the other hand, lives up to BMW's rich six-cylinder history and is a joy to drive, with a sound-track to match. The six-cylinder engine has more than enough power at any speed and audibly proclaiming its presence, especially in Sport Mode.

Handling and Driving Impressions

A BMW sports coupe has much to live up to, with a history identifying it as one of the premium driver's cars on the market. Driving the 4 Series feels right: it has excellent balance and agility, cornering with ease and responding to driver inputs rapidly. Together with naturally great engines and a good suspension system, the 4 Series delivers a breathtaking driving experience. The 4 Series also delivers on its drive-mode promises by actually changing up the driving experience accurately per selection. The suspension, steering, and engine responses are all precisely tuned for the various modes, including Comfort, Eco-Pro, Sport, and Sport Plus. Comfort mode tones down the sporty character of the car and turns it into a comfortable cruiser, while Eco-Pro reduces fuel consumption by keeping the revs as low as possible and reducing climate control strength. Sport mode livens up the drive with better throttle responses, more accurate steering, quicker shifting gears, and - of course - louder engine sounds. Sport Plus can be overkill for some, as it reduces the traction settings, makes the ride even firmer, and introduces a launch control feature.

For hardcore drivers, the M-Sport Package is available as well to increase the top speed, tighten up suspension, and add an aerodynamic kit, all aimed at increasing the performance aspect of the Coupe.

When it comes to sports coupes, BMW used to dominate with their winning combination of sporty handling and blistering performance. Nowadays, there are many worthy competitors like the Mercedes C-class Coupe, the Lexus RC350, and the Audi A5 jostling for the top spot. Although the BMW still has some tricks up its sleeve to keep them at bay, it manages to do so by only a hair's breadth.

4 Series Coupe Gas Mileage

Most sports coupe buyers aren't all that phased about fuel economy, but it remains a competitive aspect to consider. The 430i rear-wheel-drive returns EPA estimates of 24/34/29 mpg, while the all-wheel-drive version loses one point all around. The 440i offers less impressive figures of 21/32/26 mpg, with the xDrive variant managing 21/31/29 mpg. The 4 Series has a 15.8-gallon fuel tank and based on combined estimates, translates to a 458-mile range on the 430i with fifteen miles less on the xDrive version. The 440i can go 410 miles before needing to refuel whereas the xDrive manages an impressive 458 miles on one tank of gas.

4 Series Coupe Interior

As expected from BMW, the 4 Series provides a solid, well-built interior with a premium feel; a range of finishes, including different wood grains, aluminum, and chrome trim as well as leather seats make for a plush and comfortable experience overall. The steering wheel is well-shaped and comfortable, with multi-function controls easily accessible. Although there are many gauges, dials and buttons in the cockpit, they are logically laid out and intuitively placed in convenient locations across the dashboard. While not overly spacious, the 4 Series can be listed as conveniently roomy, with enough space for four passengers to sit comfortably. A sense of familiarity lingers, with many interior features linking back to other BMW derivatives. While not quite as plush as the C-Class Coupe, or as modern as the interior of the Audi A5, the 4 Series can stand its ground as a luxury vehicle from the inside.

Seating and Interior Space

The 4 Series has a surprising amount of space for four passengers, considering its coupe status. In the front, 40.4 inches of headroom and 42.2 inches of legroom are available and will accommodate a six-footer with ease. The back isn't as generous though, with limited headroom for taller adults, and legroom constrained to 33.7 inches. Further complicating matters is the unnecessarily drawn-out process for getting into the back seat, which involves a two-step procedure. Once seated, though, two adults will be relatively comfortable in the back, where a storage tray and armrest is present in the middle. While the interior dimensions of the 4 Series are not the best in this segment, it certainly fares better than the much more restrictive cabin of the C-Class.

  • Seating capacity
    4-seater

Interior Colors and Materials

A range of interior trims is available for the 4 Series, and - as is expected of a premium sports coupe - upholstered surfaces are predominantly imitation leather or the real deal. The 4 Series does not disappoint, offering three variations of SensaTec imitation leather in black or Venetian beige (with the option of red or black contrast stitching for each). Dakota leather can be had at an additional $1,550, and is available in a range of colors and combinations, including saddle brown, black, Venetian beige, coral red, and oyster. Premium BMW Individual options cost an extra $4,000 and equip top-tier models with extended Merino leather in golden brown, cashmere beige and black, nutmeg, or opal white.

Interior trim options are also comprehensive, and make use of such materials as Fineline anthracite wood or burl walnut wood trim combined with pearl gloss chrome highlights. Aluminum trim can also be optioned with Estoril blue matte accents or high-gloss black inserts; this can also be swapped out for a brushed aluminum trim. A unique ash grain wood inlay with metal highlights and pearl gloss chrome trim is also available. Once again, BMW Individual options in dark red sycamore wood, piano black or white ash grain wood trim can be equipped to the 440i for an extra $1,080.

4 Series Coupe Trunk and Cargo Space

Trunk space on a coupe often seems like an afterthought, but the 4 Series-designers have thoughtfully kept this in mind, allowing for a total cargo volume of 15.7 cubic feet, which is more than its main rivals, and even some larger sedans. While the Mercedes only provides around 10.5 cubic feet, the 4 Series can easily manage two large suitcases or a few duffel bags.

In-cabin storage is limited to a mid-sized glove compartment, storage bins in the central armrest, seatback pockets and cupholders in the front and rear. Door pockets are also available but are not particularly large. There is a decently sized passthrough from the trunk for longer items.

4 Series Coupe Infotainment and Features

Features

Although many state-of-the-art features are equipped to BMW vehicles, many elements that are standard on rivals need to be purchased additionally. Still, the 4 Series comes equipped with a rearview camera, cruise control, keyless ignition, dual-zone climate control, ten-way power-adjustable front seats, and a sunroof. Keyless entry, heated exterior mirrors, and steering-mounted controls are also standard.

Optional extras include heated front seats, a heated steering wheel, and a surround-view camera. Unfortunately, many necessary driver-assist features must be installed by means of purchasing additional bundles, which means that if you want active driving assistance, blind-spot detection, a head-up display, automatic high-beams, and onboard navigation, you need to shell out extra money, pushing up the overall price of the vehicle. Although this is slightly disappointing, it is not unique to BMW.

Infotainment

For a luxury vehicle in this price bracket, the available infotainment system is quite disappointing. There is no touchscreen, just a 6.5-inch LCD display with rotary dials that control the menu functions on it. There's also no Android Auto capability, and Apple CarPlay is only available as a $300 add-on feature. What the 4 Series does have is BMW's iDrive infotainment system, as well as Bluetooth connectivity, a CD player, HD radio, and nine speakers as standard on the base model. On the 440i, a 16-speaker Harman Kardon premium audio system is added, as well as SiriusXM Satellite Radio with three months' paid subscription. This does soften the blow of a generally aging infotainment system a bit, especially with the brilliance of a top-end audio system to distract you.

4 Series Coupe Problems and Reliability

The 2018 4 Series has had one recall for a crankshaft sensor with incorrect firmware, which could potentially result in an engine stall. Otherwise, there have been no serious complaints lodged. The 4 Series comes with a four-year/50,000 mile basic and powertrain warranty. An impressive twelve-year/unlimited-mile warranty on perforation and corrosion is also provided, as well as BMW Ultimate Care for three year/36,000 miles. There is also a four-year/unlimited mile roadside assistance plan included with every new vehicle purchased.

4 Series Coupe Safety

Neither the NHTSA nor the IIHS has tested the 4 Series comprehensively. However, it is closely related to the 3 Series Sedan and should emulate the NHTSA's overall score of five stars. The 3 Series Sedan was awarded the IIHS Top Safety Pick over the last few years as well. With sufficient onboard safety features, high ratings can safely be assumed.

Key Safety Features

While the 4 Series has basic safety covered in terms of airbags, four-wheel ABS, emergency brake assist, traction control, a rearview camera, and two sets of LATCH child-seat tethers, it leaves the more advanced driver-assist features off the standard-fit list; the disappointing result is that important tech elements such as blind-spot monitoring, blind-spot detection, park distance control, front and rear parking sensors, and adaptive cruise control must be purchased as additional packages. The same goes for automatic high beams, a surround-view camera, and a head-up display. To add insult to injury, these features are also spread out across various bundles, meaning you would need to purchase more than one to really outfit the vehicle comprehensively.

Verdict: Is the 2018 BMW 4 Series Coupe a good car?

It's almost unusual for BMW to find itself trying to measure up to rivals, but such is the case with the 4 Series Coupe - with core competitors such as the Audi A5 and the Merc C-Class gunning for the top spot in this segment as well. At least these competitors have the advantage of comprehensive feature-lists, while the 4 Series is left wanting without additional packages installed. For a premium German coupe, the infotainment system doesn't live up to expectations and lacks basic smartphone integration or even the modernity of a touchscreen. It's nonsensical in this segment to require additional costs for Apple CarPlay while much cheaper vehicles include it as standard. With extra packages almost necessary to bring the 4 Series into the arena with the A5 and Mercedes C-Class, an inflated overall price can be expected just for important elements like blind-spot detection and heated seats - features which should be standard on a vehicle of this caliber.

It's not all bad though, and the 4 Series does have the advantage of being a spectacular car to drive. It excels as an enjoyable, lifestyle-oriented coupe with impressive engine performance on the range-topping 440i, offers a quiet and serene cabin and still has the option of outfitting the legendary M Sport styling and capabilities.

What's the Price of the 2018 BMW 4 Series Coupe?

Entering the market at $43,500 for the base model 430i in rear-wheel-drive, the xDrive version ups the cost by $2,000. For the top-end 440i, an MSRP of $48,900 can be expected with rear-wheel-drive as default. The xDrive variant will set you back $51,900 without any additional packages optioned. These prices exclude and registration, licensing, and taxes, as well as a destination fee of $995. With very similar price ranges for both the C-Class and the Audi A5 at a base level, the additional cost of package-upgrades needs to be taken into account.

2018 BMW 4 Series Coupe Models

The 4 Series Coupe range consists of two models available as RWD by default with the option of xDrive on both: the 430i and the 440i. Both models feature the same eight-speed automatic transmission, although a six-speed manual version is available as well.

With a 2.0-liter four-cylinder turbo engine under the hood, the 430i produces 248 hp and 258 lb-ft. It rides on 18-inch wheels and features a sunroof as standard. With cruise control, power-folding and heated mirrors, and a rearview camera, the entry-level Coupe offers imitation leather upholstery with seats that are ten-way power-adjustable in the front. A 6.5-inch infotainment system is installed with BMW's iDrive system, and is coupled to a nine-speaker standard audio setup; basic CD, radio and Bluetooth functionality are included.

One step up, the 440i has the 320 hp, 330 lb-ft-producing 3.0-liter inline-six engine equipped. Building on the existing features from the 430i, it adds keyless entry and ignition and steps up the sound system to a more premium 16-speaker Harman Kardon setup.

Additional Packages

Sadly, the need for additional packages is high on the 4 Series - the no-charge Essentials Package comes equipped on all models, and includes park distance control, at the very least. Still, missing requisite driver assistance features must be added as stand-alone options or as part of a variety of packages. Active blind-spot detection and active driving assistant can be purchased for $500 each, while adaptive cruise control and a head-up display will set you back a further $1,200 and $1,100 respectively. The Executive Package can also be optioned, which equips the Coupe with automatic high beams, side-and top-view cameras, parking assistant, and a head-up display for $2,100.

A $2,000 Premium package is also available and will supplement on-board features with additional lumbar support, heated front seats, navigation, and remote services.

To upgrade the standard sound system to the premium Harman Kardon setup, add Dakota leather seats, and a few signature chrome exterior accents by means of the Luxury Package will set you back $1,850 on the lower-end model, and $1,450 for the top-of-the-range 440i.

For the die-hard performance-junkies, the M Sport package is available at $2,600 for 430i models and $2,550 on the 440i. This switches out standard wheels to exclusive 18-inch M star-spoke wheels, adds adaptive M Suspension and an M Sport steering wheel, as well as kitting out the Coupe with an aerodynamic body kit and Shadowline exterior trim. Various exclusive paint and cosmetic accent options are also included.

A Track Handling package is also available for further wheel options, M Sport brakes, adaptive suspension, and variable sport steering, all for an additional $1,700.

What BMW 4 Series Coupe Model Should I Buy?

It stands to reason that the more inexpensive model would be an obvious choice, but given the need to equip packages - and the fact that buying a Coupe is somewhat of an investment - buyers may as well go the whole way and opt for the 440i. It offers the more powerful engine and opens up availability to premium-level packages that will further enhance the driver's experience. Hardcore purists would want the rear-wheel-drive version with the optional six-speed manual transmission for added engagement, and would probably get the most out of the M Sport or Track Handling packages. If your goal is to invest in a luxury cruiser for relaxed outings, however, the 430i is a good choice with its lower price; this frees up your budget for some of the much-needed advanced driver safety features that need to be purchased additionally, as well as any comfort accessories that would enhance the level of luxury inside.

2018 BMW 4 Series Coupe vs Mercedes-Benz C-Class Coupe

Mercedes has always been BMW's most direct rival and the two German manufacturers have been duking it out for years, most notably in the luxury and performance segments. In this case, both entry-level Coupe's have starting costs of between $43,200 and $43,500, with Mercedes hanging on to the lower price. For the entry-spec model, the Mercedes offering churns out 241 hp and 273 lb-ft, which is not all that different from the 248 hp, 258 lb-ft 430i. Both vehicles feature similar drivetrains, with all-wheel-drive optional to both; the BMW does have the added advantage of offering a six-speed manual, though. Top-range Coupe's share fewer features in the sense that the 440i (priced at $51,900) is capable of 320 hp, while the C43 can make 362 hp, although costing $4,000 more.

Mechanics aside, the Mercedes C-Class is known for its elegant and plush interior, and as such, offers a much classier cabin than the BMW, with a better infotainment system and both Apple CarPlay and Android Auto to boot. Without the need for extensive package-customization, as well as it's better performance on the top-end model, the Mercedes C-Class Coupe is the better cruiser of the two.

2018 BMW 4 Series Coupe vs Lexus RC

Times have certainly changed when Lexus has upped their game sufficiently to allow for comparison with a BMW sports coupe - but the RC is both a testament to Lexus' improvements, as well as BMW's need to remain on their toes. While the BMW 4 Series maintains its signature good looks, Lexus has gone all out in creating a fresh, stylish, and assertive coupe. With the benefits of superior cabin craftsmanship and sublime ride quality, the Lexus is a serious contender in this segment. Differences in entry-level pricing are negligible, but basic powertrain configurations are quite different. While the 430i is powered by a 2.0-liter inline-four developing 248 hp and 258 lb-ft, the entry-point to the Lexus RC range is equipped with a similarly powered 241 hp 2.0-liter turbo, with a 3.5-liter V6 with 311 horses and 277 lb-ft available on the RC350. Not only does the Lexus impress with a powerful base engine and a smooth, comfortable ride, it is also well-specced with standard features that don't require the purchase of additional packages just to get on par with driver safety. Die-hard BMW fans will still opt for the superior dynamics of the 4 Series (especially in manual configuration), but we are inclined to give the Lexus RC the benefit of the doubt in lieu of comfort and value for money.
