Big luxurious grand-touring coupe
The BMW 6 Series is one of the most luxurious GT coupes on the market. Based on the same underpinnings as the BMW 5 Series, the 6 Series is all about long-distance refinement rather than sporty fun. With an exceptional high-end interior, striking design, and some powerful potent engines, the 6 Series is sure to please those who like to travel in luxury and style. It’s not the most practical car however, and it is expensive to buy, especially if you purchase from a 6 Series from new. Nevertheless, if you want a car that can take you in comfort, to the alps or to the golf course, the 6 Series is one of the very best that money can buy.
High end cabin, generous equipment, but not the most practical.
Sitting behind the wheel of a premium product like a BMW should make you feel special, and the 6 Series certainly achieves that. You’ll get plenty of kit for your money as well, and whilst there’s not much room for passengers, the boot is an impressive size.
The dashboard design of the 6 Series is exceptional. It’s clean, modern, and has an upmarket finish that few cars can match. Leather adorns every area of the cabin, whilst build quality is as you’d expect from a high-end car like the 6 Series. Controls are also easy to use, and the iDrive infotainment system is one of the very best on offer in the motoring world. Attractive alloy trim highlight the dials and the controls, finishing off what is an excellent interior.
Practicality isn’t one of the 6 Series’ strong points, especially if you plan on using the rear space for passengers. Legroom and headroom is limited, due to the 6 Series’ sloping design, making the rear seats useful only to children, or short journeys for adults. The 460 litre boot capacity is huge for a car of this class however, with more than enough room for a full set of golf clubs.
Equipment levels in the 6 Series are generous no matter which trim you choose to go for. The entry-level SE trim, if you can call it ‘entry-level’, comes with more kit than you can shake a stick at. You’ll get climate control, cruise control, and the iDrive infotainment centre, which is controlled through a huge tablet-style 10.2” screen. So even if you go for the most basic model, you’ll get everything you’ll ever need.
Overall the interior of the 6 Series is everything you’d expect from a grand-tourer coupe. The fit and finish is exceptional, and equipment is generous across the range. There’s not a lot of room in the back for passengers however, though the boot space is impressive for a car in this class.
On The Road
Smooth and refined, but not a great deal of fun.
Despite the 6 Series being a swooping, dynamic GT coupe, it isn’t actually as much fun to drive as it looks, especially compared to some of its rivals. The Audi A5 Coupe and Porsche 911 are both more fun on twisty country lanes. Think of the 6 Series as a long-distance cruiser however, and it does handle pretty well. The steering is sharp, and offers plenty of feedback, whilst there’s plenty of grip through the corners from the rear wheel drive chassis. The Dynamic Drive package adds to driver involvement, though it’s a very expensive optional extra.
Suspension and Chassis
Ride refinement is one area in which the 6 Series truly excels. The cabin is so well insulated that you’ll barely hear any road, wind, or engine noise, even on the motorway. This makes the 6 Series one of the very best cars for travelling long distances in comfort. The suspension is also supple, soaking up poor road surfaces with aplomb. If you want a car that can get you from Manchester to Monaco in comfort, there are few better cars on the market.
Gearbox options in the 6 Series come in only one guise. No matter which model you go for your 6 Series will be fitted with an 8-speed dual-clutch semi-automatic transmission. That’s not a problem however, as it’s perfectly suited to the car’s character. Smooth and precise in automatic mode, and sharp and responsive in manual mode, the 8-speed semi auto truly offers the best of both worlds.
Powerful, refined, and not as expensive to run as you might expect.
When it comes to deciding how you want to power your BMW 6 Series, you’ve got the usual two options: petrol, or diesel. Surprisingly, the diesel is best suited to the 6 Series, though all of the engines in the range have enough grunt to put a smile on your face when you put your foot down.
If it’s all-out power that you want from your 6 Series, the stand-out option in the range is the monstrous 650i M Sport. With an incredible 449bhp under the bonnet, the 6 Series will accelerate from 0-62mph in a blistering 4.6 seconds. This model is significantly more expensive than the rest of the range however. Because of this, it makes more sense to go for the more efficient 640d diesel engine, which is only 0.7 seconds slower to 62mph, and still packs 313bhp under the bonnet.
Eco-friendly buyers don’t usually go for big GT coupes, and for good reason. They’re not cars that care too much about the trees. Despite this, the greenest diesel-powered 640d isn’t as bad as you might expect. 143g/km CO2 emissions might not look great on paper compared to a conventional family car, but for a GT coupe they’re pretty low. Because of this, the tax bill will only cost £145 a year, which makes the 640d the best option for money savers. This becomes more apparent when you see the claimed 52.3mpg, which is match for some city cars.
Though there a wide range of engines on offer in the 6 Series, the standout option is definitely the 640d. The 640i petrol might be slightly cheaper to buy, but its running costs are significantly more expensive. And though the 650i is mightily quick, it’s not really quick enough to justify the added expense.
One of the 6 Series’ strong points, though it hasn’t yet been tested by NCAP.
BMW is a brand that has a firm focus on safety standards, so even though the 6 Series hasn’t yet been tested by NCAP, it shouldn’t be a cause for concern. Nearly all BMWs score the full 5-star NCAP safety rating, and we’d expect the 6 Series to perform equally as well. One of the great things about the 6 Series is the amount of safety equipment that you get as standard. As well as the usual array of airbags, you’ll also get electronic stability control, traction control, cameras that aid visibility at junctions, a Night Vision system that alerts you to oncoming hazards, and a head-up display that projects vital information. All in all, the 6 Series must be one of the safest cars on the roads.
Value for money
Expensive to buy from new, but avoid first year depreciation and it starts to make more sense.
The BMW 6 Series offers decent value for money if you go for a used example. Running costs do vary between model to model, but generally speaking road tax bands are reasonable for a car in the GT coupe class. Fuel efficiency really does depend on your choice however, as the 640d is perhaps the only spec in which the 6 Series comes anywhere close to being affordable, at least for the majority of drivers. Thankfully this is the best engine in the range, which is pleasing.
The cost of insurance in the 6 Series is the same no matter which model you choose to go for. Every 6 Series comes with the highest group 50 insurance. It’s not a cheap car to insure by any means, but it is roughly the same as its premium competitors, so whilst you won’t be saving lots of money, you won’t be shelling out more than you should be.
Depreciation is a large factor with the BMW 6 Series, but only if you choose to buy from new. With first year depreciation as high as 40%, you’re better off opting for an inspected used equivalent.
All in all, the BMW 6 Series coupe is a hugely impressive grand tourer. It’s not especially fun to drive, but there are few cars that can match the 6 Series for on the road refinement. So if you’re a buyers who enjoys the art of long-distance cruising, the 6 Series is the car for you. With an exceptional interior, impressive boot space, and a range of powerful engines, it’s almost the complete package. The 6 Series’ rivals may trump it in key areas, but few are as easy to live with, and are as well-rounded as the BMW 6 Series.
