420i-m-sport-5dr-step-auto

The entry-level petrol engine offers 181bhp and will officially sprint from 0-62mph in 7.9sec. It feels brisk enough, with plenty of power from low revs, and will easily get you to motorway speeds with no issues. You have to work it quite hard if you want it to feel especially fast but it’ll be more than sufficient in most situations. Our chosen engine.

420i M Sport

The M440i’s 3.0-litre turbocharged straight six is an exciting engine, producing 367bhp and firing you from 0-62mph in just 4.7sec. Working the M440i to the red line produces terrific engine sounds, too. Those after performance and practicality won’t go far wrong with the M440i.

M440i xDrive MHT

M Sport comes with plenty of standard equipment, including 18in alloy wheels, auto-dimming side mirrors, adaptive LED headlights, cruise control, front and rear parking sensors, 40/20/40 split-folding rear seats, a 12.3in digital instrument cluster, a 10.25in touchscreen infotainment system, Apple CarPlay/Android Auto smartphone mirroring, a DAB radio and built-in sat-nav.

M sport

Has the 19in alloy wheels, sportier styling, upgraded sound system, three-zone climate control and M Adaptive Suspension you get with M Sport Pro trim, but with the most powerful, six-cylinder engine.

M440i

Hatchback

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

As a cash buy, the BMW 4 Series Gran Coupé is priced very close to the standard&nbsp;<a href="https://www.whatcar.com/bmw/4-series/coupe/review/n62">BMW 4 Series</a>, making it good value if you need the extra space. At first glance, it seems expensive compared to other rivals, but the Gran Coupé only comes with high trim levels, so an&nbsp;<a href="https://www.whatcar.com/audi/a5/hatchback/review/n170">Audi A5 Sportback</a> or&nbsp;<a href="https://www.whatcar.com/mercedes-benz/cla/coupe/review/n19245">Mercedes CLA</a> with comparable equipment levels will set you back about the same.&nbsp;

The 420d will be the one for company car buyers who want a low <a href="https://www.whatcar.com/news/check-your-company-car-tax-rate/n1255">tax rate</a> because its official CO2 emissions are lower than for the petrol models’. It’s also the most economical engine, returning more than 50mpg, but adding xDrive four-wheel drive will increase fuel consumption and emissions slightly.

The 420i will be the cheapest option for anyone that wants to buy using PCP<a href="https://www.whatcar.com/tag/car-finance-advice-and-guides"> car finance</a> and, although less economical than the diesel, it’ll still manage around 41mpg. You can read about the 4 Series Gran Coupé's electric car equivalent in our full <a href="https://www.whatcar.com/bmw/i4/hatchback/review/n23575">BMW i4 review</a>.

Every 4 Series Gran Coupé comes with plenty of standard equipment. Even the entry-level M Sport has 18in alloy wheels and all the infotainment kit.&nbsp;

Upgrading to M Sport Pro Edition adds 19in alloys, sportier styling, three-zone climate control, M Adaptive Suspension, and an M Sport Differential for all engines except the 420i. The range-topping M440i is similar to M Sport Pro Edition trim but with the addition of that mighty six-cylinder engine.&nbsp;

The 4 Series Gran Coupé is too new to have featured in our 2021&nbsp;<a href="https://www.whatcar.com/news/2021-what-car-reliability-survey-brands/n23418">What Car? Reliability Survey</a> but <a href="https://www.whatcar.com/make/bmw">BMW</a> as a manufacturer placed a rather average 13th out of the 30 brands included. That's above rivals Audi and Mercedes, though.&nbsp;

When it was tested by&nbsp;<a href="https://www.whatcar.com/news/the-safest-cars-on-sale-today/n19724">Euro NCAP</a> for safety, the 4 Series scored five out of five stars. The A5 Sportback scored the same, but that was several years ago and tests have become much more stringent since, so&nbsp;while it's hard to compare the two, the 4 Series Gran Coupé might keep you safer in a crash.&nbsp;

BMW gives you plenty of standard safety equipment, including automatic emergency braking&nbsp;<a href="https://www.whatcar.com/news/what-is-aeb-and-how-does-it-work/n3283">(AEB)</a> and lane-departure assist. 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 an automatic speed limit assist.

The BMW 4 Series Gran Coupé in entry-level 420i petrol form gets the cost versus performance balance right, making it our pick of the range. It feels brisk enough and offers sufficient power low in the rev range to make town driving a breeze.&nbsp;

Out on the open road, you’ll need to work it hard to match its official 0-62mph time of 7.9sec, but when you do, it’ll hold its own against the similarly priced <a href="https://www.whatcar.com/audi/a5/hatchback/review/n170">Audi A5 Sportback</a> 35 TFSI when getting up to motorway speeds or overtaking slower cars. The more powerful 430i has 241bhp, and should get from 0-62mph in 6.2sec, but we’ve yet to try that engine.

The most powerful engine in the range is the M440i. Unlike the 420i and 430i, the 3.0-litre six-cylinder unit gets added power from a mild-hybrid system. In total, it puts 367bhp at the mercy of your right foot and will fly from a standstill to 62mph in just 4.7sec. That’s a close match for the <a href="https://www.whatcar.com/mercedes-benz/c-class/saloon/review/n70">Mercedes-AMG C43</a>&nbsp;saloon and a fraction quicker than the&nbsp;<a href="https://www.whatcar.com/audi/a5/coupe/review/n21814">Audi S5</a>. It’s thrilling to rev out to the red line, with loads of power across the board.&nbsp;

If you do lots of miles, you might want to consider the diesel offering: the 420d. It has only a few more bhp than the 420i but provides far more torque below 3000rpm and feels much quicker, as its swifter 7.3sec 0-62mph time attests. In fact, the low-down urgency makes B-road overtakes remarkably easy.&nbsp;<a href="https://www.whatcar.com/make/bmw">BMW</a> doesn't charge a lot more to add xDrive four-wheel drive, but we think it's unnecessary for most buyers.

You can’t have the 4 Series Gran Coupé with a manual gearbox, but that's no bad thing. Unlike the auto box in the&nbsp;A5 Sportback, its eight-speed automatic acts with little delay when you want to pull away and it’s more than happy to drop down a gear when you ask for a sudden burst of power.&nbsp;

Every 4 Series has ‘variable’ steering as standard, and that avoids lots of excessive arm-twirling at town speeds and when parking. At faster speeds, even tiny steering inputs have a big say on your direction, and that can make the car feel a little flighty and nervous. It’s something you get used to, though, and the effect can be mitigated by switching the steering to its Sport setting, which adds more weight to the steering and gives you more confidence.

The 4 Series Gran Coupé has quite a firm ride, even compared with the&nbsp;<a href="https://www.whatcar.com/bmw/3-series/saloon/review/n91">BMW 3 Series</a>. That works in its favour, though, and its suspension limits body lean much better than in the A5 Sportback and<a href="https://www.whatcar.com/mercedes-benz/cla/coupe/review/n19245"> Mercedes CLA</a>. It also handles more dynamically than those rivals, cornering with greater enthusiasm.&nbsp;

While entry-level M Sport trim brings conventional non-adjustable suspension, other versions have M Adaptive Suspension as standard. The adaptive&nbsp;system helps keep the car’s body incredibly flat and stable through corners. Its advantages are best felt in the M440i, which is incredibly balanced and agile, making the Audi S5 feel wallowy in comparison.

Adaptive suspension also gives the 4 Series Gran Coupé an agreeably split personality. It behaves like a sports car in its firmest mode, but if you switch to Comfort, the ride becomes more pliant than you might imagine. It’s still firmer than the A5, but thanks to its excellent damping, there’s no crashing or shuddering over broken surfaces, as there sometimes is in the S5 and Mercedes C43 AMG. BMW's M Sport models without adaptive suspension do a good job in that regard, too, but they ride more firmly overall.&nbsp;

The 420i petrol engine is generally quiet and smooth, and only really gets rorty when you put your foot down for a sudden burst of power. The 420d is prone to a bit more noise and steering wheel vibration at idle. Even so, the diesel thrum fades into the background once you’re on the move and it’s refined as diesels go, matching&nbsp;the A5 Sportback’s 40 TDI engine.

There’s some tyre noise at motorway speeds and a little more wind noise than you'll hear in the 3 Series. You can also hear the suspension working away along bumpy roads, so overall the 4 Series isn’t as quiet to travel in as the A5.

The BMW 4 Series Gran Coupé&nbsp;has its work cut out for it, because being all things to all drivers is pretty tough

You see, the 4 Series Gran Coupé straddles car niches, aiming to combine the style of the <a href="https://www.whatcar.com/best/best-coupes-2022/n17019">best coupes</a> and the comfort of a five-door saloon, with the added practicality of a hatchback’s wide-opening tailgate.&nbsp;

That might sound like a bit of a tall order, but as long as&nbsp;<a href="https://www.whatcar.com/make/bmw">BMW</a> hasn’t settled for any half measures in any of the areas, it should be a recipe for success. After all, it's based on the<a href="https://www.whatcar.com/bmw/4-series/coupe/review/n62"> BMW 4 Series</a>&nbsp;– a winner of the What Car? Car of the Year Coupe category.

The Gran Coupé's competition includes the<a href="https://www.whatcar.com/audi/a5/hatchback/review/n170"> Audi A5 Sportback</a>,<a href="https://www.whatcar.com/mercedes-benz/cla/coupe/review/n19245"> Mercedes CLA</a> and slightly more left-field rivals, including the<a href="https://www.whatcar.com/kia/stinger/saloon/review/n177"> Kia Stinger</a> and<a href="https://www.whatcar.com/volkswagen/arteon/hatchback/review/n176"> Volkswagen Arteon</a>. So, how well equipped is it to compete with the other&nbsp;<a href="https://www.whatcar.com/category/coupe">coupes</a> you might be considering?

Well, you can have your BMW 4 Series Gran Coupé with a choice of two petrol engines, with power outputs of 181bhp and 241bhp, or one diesel that’s available with xDrive four-wheel drive for added traction. Fancy even more power? There's also the range-topping six-cylinder petrol M440i.

It all sounds pretty promising, but should you choose one over any of its rivals? Stick with us over the next few pages of this review, as we tell you whether the BMW 4 Series Gran Coupé is as good as it looks. Our road testers have rated it in in all the important areas, including&nbsp;performance, comfort, practicality and reliability.

By the way, if you're thinking of going electric, the 4 Series Gran Coupé has an electrified twin. You can read about that in our <a href="https://www.whatcar.com/bmw/i4/hatchback/review/n23575">BMW i4 review</a>.

When you’ve decided which make and model is the right one for you, don’t forget to search our free<a href="https://www.whatcar.com/new-car-deals"> What Car? New Car Deals pages</a>&nbsp;to see how much you could save without any haggling. It's a good place to look for the best <a href="https://www.whatcar.com/new-car-deals/category/coupe">new coupe deals</a>.

If you like sporty driving positions, you’ll enjoy how the BMW 4 Series Gran Coupé seats you low down. There's also lots of seat and steering wheel adjustment to help you find a comfortable position.

You don’t get adjustable lumbar support as standard with any trim level though, which is disappointing – even the entry-level<a href="https://www.whatcar.com/audi/a5/hatchback/review/n170"> Audi A5 Sportback</a> includes that. Other than its pedals being slightly offset to the right, the Gran Coupé’s driving position is otherwise very good, with clear instruments and controls that are well laid out.

Interior quality is on a par with the A5 and better than in the<a href="https://www.whatcar.com/mercedes-benz/c-class/coupe/review/n17151"> Mercedes C-Class Coupé</a>. The materials used are pleasant, and although there are some hard plastics, they're not in places you’ll touch often. The slightly tacky looking silver-painted buttons on the dashboard let the side down a bit, though.&nbsp;

The 4 Series Gran Coupe's infotainment system is truly brilliant. All versions get a 10.3in display that you can either use as a touchscreen or operate by twisting and pressing the rotary controller between the front seats. The rotary controller is&nbsp;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 system to the A5’s.

<a href="https://www.whatcar.com/make/bmw">BMW</a> gives you&nbsp;<a href="https://www.whatcar.com/advice/owning/what-is-android-auto/n1194">Android Auto</a>&nbsp;and&nbsp;<a href="https://www.whatcar.com/advice/owning/what-is-apple-carplay/n1193">Apple CarPlay</a>&nbsp;smartphone mirroring on all trims so you can use your phone apps on the touchscreen. You also get DAB radio and built-in sat-nav. For more toys, the optional Technology Pack adds an upgraded Harman Kardon sound system, wireless phone-charging and a gimmicky gesture control function for the infotainment.

A good mix of comfort, practicality and fun driving

BMW 4 Series Gran Coupe

There’s plenty of space in the front of the BMW 4 Series Gran Coupé for the driver and passenger, with loads of shoulder room and ample headroom for even those measuring more than six feet tall. Storage space is good too, thanks to a big glovebox, a useful cubby under the centre armrest, two cup holders, a tray for storing your phone and decently sized door bins.

Rear space is where the 4 Series Gran Coupé sets itself apart from the standard <a href="https://www.whatcar.com/bmw/4-series/coupe/review/n62">BMW 4 Series</a>&nbsp;though. For starters, the presence of rear doors makes climbing into the rear seats an absolute breeze. There’s also slightly more headroom and legroom for rear-seat passengers, although six footers will still find their heads grazing the roof lining.&nbsp;

That’s even more true of the middle. The centre seat is raised slightly, so even those just under six feet tall will find themselves having to bend slightly due to the limited headroom. When you don’t have a middle passenger, you can fold down part of the seat to create an armrest with two cup holders.&nbsp;

At 470 litres, the 4 Series Gran Coupé's boot is 30 litres bigger than that of the regular 4 Series. It’s also a little bigger than those of the<a href="https://www.whatcar.com/audi/a5/hatchback/review/n170"> Audi A5 Sportback</a> – which we managed to squeeze seven carry-on suitcases into – and the <a href="https://www.whatcar.com/mercedes-benz/cla/coupe/review/n19245">Mercedes CLA</a>. The Gran Coupé will easily swallow a pushchair or a large weekly shop. Because it's a hatchback, it's easy to load and unload, too.

The rear seats can be split 40/20/40 and then folded to reveal an extended and totally flat loading bay. The A5 Sportback and CLA back seats split in the same versatile 40/20/40 configuration.&nbsp;&nbsp;

If boot space is of great importance to you, you might want to consider the larger<a href="https://www.whatcar.com/volkswagen/arteon/hatchback/review/n176"> Volkswagen Arteon</a> as it offers more boot space than the Gran Coupé&nbsp;or any of its rivals and will happily swallow an additional carry-on suitcase.

The BMW 4 Series Gran Coupé is practical, stylish and fun to drive. The hatchback tailgate makes loading and unloading a breeze and the extra space will be alluring to those who want a coupe but don’t want the accompanying sacrifices. The M440i takes that one step further by adding explosive performance to that practicality. 

<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.

Coupe

<h2>What we're looking for:</h2><ul><li>Entertainingly agile handling</li> <li>Eye-widening acceleration</li> <li>Fruity exhaust note</li> <li>Punchy and characterful engine</li> <li>Great driving position</li> <li>Everyday usability</li></ul>

The best performance cars combine sports car-rivalling acceleration with&nbsp;engaging handling. However, they also retain the&nbsp;impressive everyday usability of the conventional saloons and estates on which they're based.

Performance car

<h2>What we're looking for:</h2><ul><li>Effortless long-distance capability</li> <li>Strong standard specification</li> <li>Low running costs</li> <li>Comfortable driving position</li> <li>Comprehensive yet easy-to-use infotainment system</li></ul>

Executive cars are often the choice of company car drivers, so factors such as CO2 emissions (which govern your monthly tax bill) are just as important as cruising refinement for those long motorway journeys, a plush cabin and (whisper it) the image of the badge on the bonnet.

The good news is that there are options for all budgets and tastes.
