The Auto Trader verdict
★★★★★
★★★★★
3.5
The 6 Series, dynamically at least, is designed to do a very specific job, and that’s to belt up and down motorways quickly and comfortably, not to blast along B-roads at breakneck speeds. So long as you remember that, you’ll love the big Beemer. It looks great, it’s comfortable and refined, it has a luxurious, technology-filled interior, and it’s practical enough for weekend trips. It’s a car you will find yourself respecting rather than loving, but for many drivers, that won’t matter a jot.

Pros

  • All versions deliver strong performance and refinement
  • Comfortable and capable on the road
  • Interior quality is excellent

Cons

  • Many ‘four-door coupe’ rivals are more practical
  • Reliability record is of some concern
  • Some important safety kit costs you extra

BMW 6 Series Coupe

Exterior
★★★★★
★★★★★
4/5

If you buy a large coupe like the 6 Series, chances are you’re more than a little bit interested in looking good. The big BMW achieves that, but in a refreshingly understated way. There are plenty of features to identify it as a BMW – such as the famous kidney grille – along with the long bonnet and plunging roofline that mark it out as a coupe. However, the overall effect isn’t overly shouty or in-your-face, communicating instead a message of quiet sophistication. Entry-level SE versions have 18-inch alloys and LED headlamps, while Sport versions add bigger wheels and a few glossy black exterior trims. M Sport versions add some chrome flourishes and a subtle-yet-effective bodykit. There’s nothing subtle about the way the range-topping M6 version looks, but if you go for such a fast, extravagant version of the car, there’s every chance you want people to know about it.

Interior
★★★★★
★★★★★
4/5

The cabin of the 6 Series is exactly what you’d expect from a high-end BMW. The quality is absolutely top-drawer, with dense, tactile materials everywhere you look and a flawless standard of fit and finish. The luxury toys on display – such as the huge high-definition central screen and the posh-looking digital ventilation controls – make the cabin feel as high-tech as it does high-end, and it all adds up to a very sophisticated feel. The infotainment system is one of the most intuitive of its type, with logical menus, sharp graphics and fast responses, while the other controls are also easy to find and use. The driving position has lots of electric adjustment, making it easy to get comfortable, and despite the swooping roofline, your rearward visibility isn’t too bad when compared with other large coupes.

Practicality
★★★★★
★★★★★
3/5

The 6 Series does a thoroughly decent job in this area when compared with other big prestige coupes. The boot is a very useful size at 460 litres, and because the space is wide and deep, it’ll fit a couple of sets of golf clubs or a few shopping bags. Bear in mind, though, the space is also rather shallow, meaning many bulkier items will be a no-no. The front seats have loads of space for tall adults to stretch out, and there’s also plenty of storage space in the cabin. The rear seats are predictably tight on space, with limited knee- and head-room on offer, but there’s enough for a pair of adults to cope on shorter journeys. That said, many manufacturers – BMW included – offer ‘four-door coupes’ these days, which provide the slinky looks with extra space and versatility. If practicality is of particular importance in your buying decision, you might be better off with one of those instead.

Ride and handling
★★★★★
★★★★★
4/5

So far, we’ve only tried the 6 Series with the optional Adaptive Drive variable suspension, and with this fitted, the car is a very competent performer. The ride is edgy enough to give you a feeling of connection with the road, but smooth enough to keep you comfortable and relaxed in most situations. The quietness of the car contributes to that serene feel as well, because noise from the engine and the wind are really well isolated, although a bit more road noise does make it through to the cabin. Nevertheless, this is a car that’ll happily destroy huge distances in a single hit, delivering you to your destination fresh and calm. It’s not half bad in the corners, either, with lots of grip, reassuringly weighty steering, and sharp control over body movement when you’re changing direction. Anyone expecting this to be a sportscar will be disappointed – it’s too big and heavy for that and the steering doesn’t give to the required amount of feedback – but if you judge this car as the grand tourer it was designed to be, you’ll be perfectly satisfied.

Performance
★★★★★
★★★★★
4/5

So far, the only version of the 6 Series we’ve sampled is the 640d, which is powered by a 3.0-litre diesel engine developing 309bhp. It suits the car incredibly well, not just because it’s hugely fast, but because it provides mighty pull in the lower and middle parts of the rev range, making acceleration a very easy – not to mention exceptionally brisk – affair. More pertinently, this strong urge is accompanied by exemplary refinement. The engine emits a creamy growl when you extend it, but the rest of the time it stays quiet, smooth and relaxed. The other engines on offer are all petrols, and each will see off the 0-62mph dash in less than 5.5 seconds. The 640i’s 3.0-litre six-cylinder engine develops 316bhp, the 650i’s 4.4-litre V8 has 444bhp, while the M6 has a fire-breathing V8 that serves up 552bhp. If that’s not already nuttier than a squirrel’s shopping list, there’s a performance upgrade available that makes the M6’s power output even more ludicrous. The M6 channels its power through a seven-speed twin-clutch gearbox, while the rest have a nine-speed automatic.

Running costs
★★★★★
★★★★★
3/5

The 6 Series is not a cheap car to buy, but as a high-end BMW, that’ll be of absolutely no surprise to anyone. Is it competitive on price when compared with its rivals? Well, it has very few direct rivals in terms of its size and the number of doors and seats it has, so it really depends what other models you compare it with. It’s a lot more expensive than the Mercedes E-Class Coupe, which is a little smaller, but much cheaper than the S-Class Coupe, which is a little bigger. Choosing the diesel will get you an average fuel return of around 50mpg, according to official figures, but none of the petrols get anywhere near that; even the cleanest can only just beat 37mpg. The correspondingly high CO2 emissions means tax bills will also sting. Still, resale values are pretty strong due to the car’s desirability, which should help safeguard the amount you’ll pay to own your car long-term.

Reliability
★★★★★
★★★★★
3/5

Look at the Warranty Direct Reliability Index, and you may be a little concerned about how dependable your 6 Series will be. The car has a pretty rubbish rating traditionally, making it one of BMW’s poorer performers, and the brand itself occupies a disappointingly lowly position in the same study’s manufacturer rankings. Our owner reviews don’t report any reliability horror stories, though, and the three-year/unlimited-mileage warranty you get as standard is pretty good.

Safety
★★★★★
★★★★★
3/5

The 6 Series isn’t exactly a game-changer in this area. It comes with a vast suite of electronic driver aids to help you avoid getting into trouble, but it only comes with four airbags as standard and you’re charged extra if you want a suite of safety systems including Lane Departure Warning and Automatic Emergency Braking with Pedestrian Protection. It’s not a massive sum, but it’s a bit stingy that it’s not provided as standard on a car this expensive. If you want to upgrade it further to include a system that’ll help you drive the car in stop-start traffic, you’ll pay thousands rather than hundreds. The 6 Series hasn’t been tested by Euro NCAP, but it’s based on the same architecture as the 5 Series, which achieved the full five-star rating, albeit back in 2010 when the tests were much easier than they are now.

Equipment
★★★★★
★★★★★
4/5

You’d expect a car like the 6 Series to come stocked with plenty of luxury kit, and it doesn’t disappoint. Even the entry-level SE car has leather upholstery, climate control, cruise control, front and rear parking sensors, heated front seats, a multi-function steering wheel, and a high-end infotainment system that brings together navigation, DAB radio, 20GB hard drive, advanced Bluetooth with wireless phone charging (where your phone is compatible), plus a whole bunch of connected services. Sport models add comfier seats with posher leather, but otherwise, the upgrades are purely aesthetic, and it’s a very similar story with M Sport trim. The M6 does have all sorts of performance enhancing gear aimed at controlling its vast power, but in terms of luxury kit, it’s very similar to the rest of the range.

Why buy?
★★★★★
★★★★★
3/5

Because you want a big, luxurious car with plenty of style, and one that can transport you vast distances comfortably and quietly. On that score the 6 Series fits the bill well. However, although the 6 Series is pretty short on direct competitors, there are lots of other cars playing that role just as well, but that also offer more practicality, more entertainment or more affordability. A good car, but possibly an acquired taste.

Pick of the range
640d SE
Strong refined engine has realistic economy, and SE has all the toys you really need.
Most economical
640d SE
Smaller wheels mean the SE is slightly less thirsty than sportier versions.
Best avoided
650i M Sport
Very nice, but occupies a weird middle-ground between the cheaper 640i and the faster M6.
