420i-m-sport-2dr-step-auto

This entry level 2.0-litre turbocharged petrol engine has 181bhp for 0-62mph in 8.2sec. Claimed fuel economy in the mid to high 40s is impressive, and the CO2 emissions aren’t bad, either.

420i xDrive

A 3.0-litre six-cylinder petrol engine that pumps out 369bhp, which is fed to all four wheels via an eight-speed automatic gearbox. If you’re thinking that sounds like a recipe for some explosive acceleration, you’d be right. Indeed, the M440i can hit 62mph from a standstill in just 4.5sec.

M440i xDrive MHT

M Sport trim comes with plenty of standard goodies, including 18in alloys, leather seats (heated in the front), cruise control and climate control. We’d recommend forking out extra for adjustable lumbar support, and, if you can, the M Sport Pro pack for the adaptive suspension.

M Sport

The range-topping M440i is very similarly equipped to the M Sport Pro Edition, but comes with a mighty six-cylinder turbocharged petrol engine.

Coupe

Munich-based BMW is most famous for its sports saloons, in particular the 3 Series and 5 Series. However, it actually builds almost every type of car imaginable: everything from two-seat convertibles to seven-seat MPVs.

The cheapest model in the BMW range is the 1 Series hatchback, which is a rival to the Audi A3, Mercedes-Benz A-Class and Volkswagen Golf. Meanwhile, at the other extreme is the M8&nbsp;grand tourer, which costs more than £120,000.

BMW was also quick to capitalise on the rise of the SUV and now has ten in its range: the X1, X2, X3, X4, X5, X6, X7 and XM, plus the electric iX3 and iX.

All of this makes it one of the big three German prestige brands, along with Audi and Mercedes-Benz.

Costs & verdict

The entry-level BMW 4 Series Coupé&nbsp;is slightly more expensive than the Audi A5&nbsp;Coupé, but is also better-specced and more powerful. If you look at similarly specced versions of both cars, there's not much difference in price.&nbsp;

The 4 Series is expected to hold its value against depreciation better than rival coupés which can help reduce PCP finance payments. Check out the latest prices on our new <a href="https://www.whatcar.com/new-car-deals/make/bmw">BMW deals page</a>.

The range kicks off with sporty M Sport trim, which comes with plenty of standard goodies, including 18in alloys, leather seats (heated in the front), cruise control and three-zone climate control.

We’d recommend paying extra for adjustable lumbar support and getting the M Sport Pro pack for its adaptive suspension. That also brings a small boot-lid spoiler, larger 19in wheels and an upgraded sound system.

M Sport Pro Edition gives you a choice of three exclusive exterior colours and adds 19in alloys, sportier styling, tinted windows and the M Sport Pro Package. The range-topping M440i is very similarly equipped to the M Sport Pro Edition but, of course, you get that mighty six-cylinder turbocharged petrol engine under the bonnet.

The latest 4 Series didn't feature in our 2023 <a href="https://www.whatcar.com/news/reliability-survey-most-reliable-cars/n26137">What Car? Reliability Survey</a> but<a href="https://www.whatcar.com/new-car-deals/make/bmw"> BMW</a> finished in 12th place out of 32 brands (Audi came 26th and Mercedes in 24th).

The 4 Series comes with a three-year warranty with no mileage cap, which is good for the class because many rivals have a mileage limit.

Safety experts <a href="https://www.whatcar.com/news/the-safest-cars-on-sale-today/n19724">Euro NCAP</a> tested the 4 Series (in conjunction with the <a href="https://www.whatcar.com/bmw/3-series/saloon/review/n91">BMW 3 Series</a>) in 2019 and awarded it the full five-star rating. It achieved highly impressive scores for front occupants in each specific area that was tested.

It has plenty of safety kit as standard, including automatic emergency braking (<a href="https://www.whatcar.com/news/what-is-aeb-and-how-does-it-work/n3283">AEB</a>) and lane-departure warning. The optional Driving Assistant Professional pack (which comes as part of the Technology Plus Pack) adds adaptive cruise control, a more advanced lane-keeping assistant, a front cross-traffic alert system and automatic speed-limit assist.

The entry-level engine for the BMW 4 Series Coupé is the 181bhp petrol in the&nbsp;420i, which has&nbsp;rear-wheel-drive and is our pick of the range.

With a 0-62mph time of 7.5 seconds, it's quick enough to be fun and loves to be revved, which is in keeping with the character of a sporty <a href="https://www.whatcar.com/best/coupes/n17019">coupé&nbsp;car</a>.

The other engine option is the six-cylinder, 3.0-litre petrol in the M440i. With&nbsp;369bhp, it has a lot more power than the 420i – so it's&nbsp;a good job it's fed to all four wheels for better traction.

Indeed, the M440i&nbsp;gets going so well that it can hit 62mph from a standstill in just 4.5 seconds, which is only slightly behind the Mercedes CLE 450’s official time (4.4 seconds). It feels pleasingly potent from low down in the rev range, and is more than happy to keep singing all the way to its red line.

For even more performance, you'll want the 503bhp M version – to read about that, see our <a href="https://www.whatcar.com/bmw/m4/coupe/review/n17199">BMW M4 review</a>.

Whichever engine you choose, you get an <a href="https://www.whatcar.com/advice/buying/automatic-gearboxes-everything-you-need-to-know/n17022">automatic gearbox</a> that makes slick changes, especially in Sport mode. You can also take control yourself using the shift paddles mounted on the steering wheel.

Every 4 Series gets variable steering as standard. It ramps up assistance to save you from excessive arm-twirling when parking, but offers less help on faster roads to prevent the car from feeling hyper-reactive to tiny steering adjustments.

It's not perfect, because the car can still feel a bit sensitive to quick inputs at higher speeds. That can be mitigated by switching to Sport mode, which adds weight to the steering to give a greater sense of connection to the front wheels and make it easier to judge how much input is required.

The 4 Series' standard passive suspension is noticeably stiffer than the set-up in the BMW 3 Series and that in turn reduces body leaning, allowing you to scythe through corners more enthusiastically than in an Audi A5 or a CLE.

However, because it's more focused on delivering poise and control than wafty comfort, you feel more of bumps as they pass beneath the car than in the best versions of the A5.

For that reason, we recommend the optional adaptive suspension that comes as part of the M Sport Pro Package (which is standard on M Sport Pro Edition models and on the M440i). That lets you stiffen or soften the ride at the touch of the button. Comfort mode makes the 4 Series much calmer around town and delivers a very smooth ride on A-roads and motorways.&nbsp;

In terms of refinement, the 420i is smooth and quiet enough when you’re pottering around, with a more rorty edge when pushed hard. Meanwhile, the M440i is the best sounding 4 Series – its six-cylinder engine noise is wonderfully soulful.

Every 4 Series (except the M4) has&nbsp;<a href="https://www.whatcar.com/advice/buying/what-is-a-mild-hybrid-and-should-you-buy-one/n22776">mild-hybrid technology</a>, giving it the ability to run with the engine switched off in certain situations. It helps to smooth out the start/stop system and means the 4 Series is far less hesitant than the A5 when setting off.

Happily, there isn't much wind noise at motorway speeds, with only a bit of wind whistling from around the front windows. There's a fair amount of road noise filtering up through the floor, but the engines fade into the background at a cruise.

Historically, BMW coupés have simply&nbsp;been swoopier, less practical versions of their saloon car counterparts. Not any more –&nbsp;the&nbsp;BMW 4 Series Coupé&nbsp;is a rakish model in its own right.

Sure, the 4 Series is&nbsp;still based on the same underpinnings as the more sensibly shaped <a href="https://www.whatcar.com/bmw/3-series/saloon/review/n91">BMW 3 Series</a>&nbsp;but the differences go well beyond losing the two rear doors. BMW has widened the car's rear, lowered the centre of gravity, retuned the suspension and stiffened the chassis.

All that should help make the 4 Series even more agile and capable than the saloon through the corners. In other words, BMW has worked hard to make sure this&nbsp;a car with the performance to match its sleeker looks.

So, has it succeeded – and is the BMW 4 Series a better buy than an <a href="https://www.whatcar.com/audi/a5/coupe/review/n17191">Audi A5 Coupé</a> or <a href="https://www.whatcar.com/mercedes-benz/cle/coupe/review/n26434">Mercedes CLE</a>? Read on to find out (or if you want a soft-top, check out our <a href="https://www.whatcar.com/bmw/4-series/sports/review/n173">BMW 4 Series Convertible review</a>)...

If there’s one area where the BMW 4 Series Coupé feels just like the 3 Series, it’s the interior. The driving position, for example, is almost identical, as are the dashboard and infotainment system.

In many ways, that's great news. It means you get a comfortable and supportive driver’s seat (as long as you add optional adjustable lumbar support) and lots of adjustment. If you want a sporty feel, you’ll probably also appreciate the fact that you sit closer to the road than in the Audi A5.

Forward visibility is good, with windscreen pillars that are slim enough not to get in the way at junctions.

Rear visibility isn’t so great, because the&nbsp;headrests on the back seats block much of the small rear screen and&nbsp;the chunky rear pillars obstruct your rear three-quarter view. Helpfully, front and rear parking sensors, plus a rear-view camera are standard on all versions of the 4 Series.

Likewise, every 4 Series has adaptive LED headlights for safe driving at night. They maintain maximum illumination without dazzling other drivers. The optional Laserlight matrix headlights are even brighter.

True, interior quality isn’t quite up there with the A5, but the margins are small. Build quality is first rate and slightly better than in the Mercedes CLE. Only a few bits of hard plastic let&nbsp;the side down a little.&nbsp;

The infotainment system in the 4 Series is brilliant. All versions get a 14.9in display that you can either use as a touchscreen or operate by twisting and pressing a rotary controller between the front seats.

The controller is much less distracting when you’re driving and, combined with a super-intuitive operating system, is one of the main reasons we prefer the 4 Series’ infotainment to the A5’s and CLE’s.

The only slight downside is that adjusting the climate controls now requires use of the touchscreen (the latest facelift got rid of user-friendly physical buttons lower down on the dashboard).

Meanwhile, a crisp-looking 12.3in digital driver display that comes as standard with all trim levels sits beside it. It shows lots of information, even if it doesn’t offer as many layouts as the ones in the A5 and CLE.

All trims come with a DAB radio, built-in sat-nav, and <a href="https://www.whatcar.com/advice/owning/what-is-android-auto/n1194">Android Auto</a> and <a href="https://www.whatcar.com/advice/owning/what-is-apple-carplay/n1193">Apple CarPlay</a> smartphone mirroring (so you can run your phone apps through the touchscreen). The optional 464W, 16-speaker Harman Kardon sound system (available in Technology and Technology Plus packs, or as a standalone option) sounds epic.

Wireless phone-charging is provided as part of the Technology Pack, which also happens to include a rather gimmicky gesture control function for the infotainment system.

<h2>Interior overview</h2>

Strengths User-friendly infotainment system; classy, high-quality interior

Weaknesses None that we’ve seen so far

The 4 Series Coupé is great to drive, smart inside and reasonably roomy

No one buys a two-door coupé like the BMW 4 Series for practicality, but the chances are you occasionally need four seats and a usable boot (otherwise, you'd be checking out <a href="https://www.whatcar.com/best/sports-cars/n24412">our favourite sports cars</a>).

The 4 Series is as spacious as a <a href="https://www.whatcar.com/bmw/3-series/saloon/review/n91">BMW 3 Series</a> in the front, so you’re unlikely to have any problems with head or leg room. Storage space is impressive, too, with a big glovebox and a decent cubby under the centre armrest.

Getting into the back seats involves squeezing through a relatively narrow gap, but that’s true of any car lacking rear doors. (If you want&nbsp;four doors and coupé styling, take a look at the&nbsp;<a href="https://www.whatcar.com/bmw/4-series/hatchback/review/n17260">BMW 4 Series Gran Coupé</a>).

Once you’re in the back of the 4 Series, you’ll find plenty of leg room, and although taller adults will need to cower slightly or put up with their head resting on the ceiling, two six-footers will be comfortable enough in the back as long as the journey isn’t too long.

The 4 Series Coupé has a 440-litre boot, which is slightly smaller than the Audi A5&nbsp;Coupé's but a little bigger than the Mercedes CLE’s.

There’s enough space for a set of golf clubs or a small pushchair, and the rear seat backs fold down in a 40/20/40 split so&nbsp;you can carry longer loads. The boot opening is smaller than the A5’s.

<h2>Practicality overview</h2>

Strengths Plenty of space up front; the rear seats are a good size

Weaknesses Boot opening could be a touch wider

m440i

The BMW 4 Series is great to drive, smart inside and roomier than you might imagine. With its powerful engine, the M440i is great fun, but the 420i strikes the best balance between performance and running costs while still impressing on a twisty road.

<h2>What we're looking for:</h2><ul><li>Strong performance</li> <li>Good balance between ride and handling</li> <li>Excellent build quality</li> <li>Decent practicality</li> <li>Sophisticated interior</li></ul>

Coupés are all about style, but while practicality undoubtedly takes a back seat to aesthetics, these cars still need to be easy to live with on a daily basis. It’s this that distinguishes a coupé from an out-and-out sports car.

Fortunately, there’s a wide range of style-focused models available, and you don’t even need to spend silly money to buy or run one.
