BMW 6 Series for Sale

Edmunds' Expert Review

by Carlos Lago

Pros

Both engines provide strong acceleration
Attractive interior design and customization options
Convertible doesn't excessively compromise trunk space

Cons

Compact rear seats and tight rear-seating area
Some competitors are a bit more exciting to drive
Android Auto is not available, and Apple CarPlay not standard

What’s new

The two-door coupe is no longer available. Aside from minor option changes, the 6 Series is otherwise unchanged.

Vehicle overview

There are few cars left like the BMW 6 Series, and fewer still with BMW discontinuing the 6 Series coupe for 2018. While we expect a new generation will debut next year, this year's 6 Series remains an excellent choice for luxury drop-top cruising.

Of course, there are sportier and smaller four-seat convertibles, and there are significantly more expensive ones too. But few can match the BMW 6 Series' blend of style, quality and comfort. Drivers will find both engine options satisfying, while available all-wheel drive allows four-season practicality. While the current generation is dated, we still think the 2018 6 Series is worth considering if you're looking for a stylish luxury convertible.

Edmunds' Expert Rating

There are few cars left like the BMW 6 Series, and fewer still with the discontinuation of the coupe for 2018. While we expect a new generation of the large coupe and convertible from BMW next year, this year's 6 Series remains an excellent choice for luxury drop-top cruising.

Trim tested

Edmunds has not yet driven any version of this vehicle. The following is our first take on what's significant about it and what you can expect.

Driving

The 2018 BMW 6 Series prioritizes comfort over sporty handling. Nevertheless, most drivers will enjoy the driving experience. The 6 Series rides comfortably over bumps, and there's plenty of power from both engine choices.

Comfort

The 6 Series is a benchmark for front passenger comfort, with multi-adjustable seats and high-quality leather. Cramped rear seats are the unfortunate norm for four-seat convertibles.

Interior

Premium leather and attractive plastics adorn the 6 Series' interior. Operating most controls makes immediate sense, though the shifter takes a little getting used to. The convertible roof limits rear visibility, but that's a problem easily solved by putting the top down.

Utility

The 6 Series offers 12.4 cubic feet of trunk space with the top up and 10.6 cubic feet with the top down. That's quite roomy for a four-seat convertible at this price. A pass-through accommodates longer objects.

Technology

BMW's iDrive infotainment system is very useful once you learn it, and optional gizmos such as night vision easily impress. Still, we're disappointed that only Apple CarPlay is supported and not standard equipment.

Which 6 Series does Edmunds recommend?

The 650i sDrive is an easy choice. On top of a bigger and more powerful engine, this trim comes standard with some options you'd want from a luxury grand tourer, such as extra seat adjustability and a higher-quality sound system. All-wheel drive adds little benefit and extra weight that makes the car less fun to drive, so unless you plan for snow we recommend the rear-wheel-drive sDrive. If the V8 seems like overkill, the 640i's six-cylinder engine remains a potent, less expensive and more fuel-efficient option. Plus, you can still option everything from the V8.

Compare 2018 BMW 6 Series trim levels

2018 BMW 6 Series models

The 2018 BMW 6 Series is a four-seat convertible available in 640i and 650i trims. Some differences exist between the two (wheel size, the sound system and level of seat adjustability, for instance), but the trims primarily designate the type of the engine. The 640i has the six-cylinder, and the 650i has the V8. BMW makes every option and package available for both trims, ensuring variety no matter which engine you pick. Rear-wheel drive, which BMW calls sDrive, is standard, and all-wheel drive (xDrive) is optional.

Under the hood for the 640i is a turbocharged 3.0-liter engine (315 horsepower, 332 pound-feet of torque). An eight-speed automatic is the only transmission choice. Standard feature highlights include 18-inch wheels wrapped in all-season tires, keyless entry, a rearview camera, parking sensors, heated front seats, automatic high beams, navigation, Bluetooth, wireless phone charging, Wi-Fi hotspot, and a nine-speaker sound system.

The 650i adds a powerful turbocharged 4.4-liter V8 (445 hp, 480 lb-ft of torque). Aside from the engine, this trim gains a few features that are optional on the 640i, such as 19-inch wheels, upgraded power adjustable seats and a 12-speaker Harman Kardon sound system.

BMW offers a variety of premium color, upholstery and trim upgrades, providing buyers plenty of opportunities for personalization. While some stand-alone options are available, most upgrades are grouped in packages. A heated steering wheel only comes in the Cold Weather package, for instance, and you must order the Executive package for ventilated seats. The M Sport package introduces a sport body kit, a sport steering wheel, a higher top-speed limit, and package-specific 19-inch wheels with either all-season or summer tires.

Blind-spot monitoring is not standard but is available in the Driving Assistance package, which also includes a head-up display, lane departure warning, and front collision warning with low-speed automatic braking. An upgraded Driving Assistance Plus package adds adaptive cruise control and enhanced front collision mitigation. When you select the Parking Assistant package you get an automated parking system and side- and top-view cameras.

Owners' Opinions

What Owners Like

Owners of the 2018 BMW 6 Series consistently appreciate its blend of power, luxury, and distinctive style. The 6 Series’ powerful engines, particularly in the 650i, receive high praise for their smooth and strong acceleration, which enhances the joy of driving both on highways and twisting roads. The interior is not only visually appealing but is also made with high-quality materials, which many drivers have come to love, often likening the cabin experience to that of a luxury grand tourer. Comfort remains a standout, especially in the front seats, with many owners finding it their go-to car for long-distance drives. Despite its weight, the BMW 6 Series maintains a comfortable ride quality, with the convertible soft top and associated trunk space allowing for impressive versatility. Several owners have highlighted the car's excellent build quality and reliable performance, which helps justifying the premium price tag. Additionally, features like the head-up display and various driving modes, such as sport mode, add to the engaging and satisfying driving experience.

Common Issues

Owners of the 2018 BMW 6 Series frequently mention the drawbacks of its heavy weight, which impacts the car's agility and handling precision. Many drivers find the factory-equipped run-flat tires to be a significant downside, contributing to a harsher ride and being prone to expensive replacements. Although the convertible model offers commendable trunk space, the rear seating area is often noted to be tight and impractical for passengers during longer trips. Handling quirks become apparent on twisty roads, where the car tends to feel less stable and boat-like, somewhat diminishing the sporty driving feel expected from a BMW. Some owners have faced frustration with the interior’s visibility constraints imposed by the raised convertible roof, although putting the top down mitigates this issue. Additionally, inclement weather conditions, such as cold or snowy environments, can present issues, such as the gas cap freezing shut. The absence of standard smartphone integration options, such as Android Auto, leaves some tech-savvy drivers feeling disappointed with the otherwise robust technology suite.

Final Takeaways from Everyday Drivers

The everyday driving experience of the 2018 BMW 6 Series is largely marked by a sense of satisfaction tinged with a few recurrent concerns. Owners appreciate the car's undeniable presence on the road, with its sleek design and powerful engine drawing admiration and turning heads. For many, the comfort of the front seats and the smoothness of the ride make it a preferred choice for long journeys. Nevertheless, some are occasionally reminded of the car's substantial weight when navigating more challenging or twisty roads, where the agility falls short of typical sports car expectations. The practicality of the convertible's trunk space, even with the top down, provides added convenience that's favored by drivers undertaking weekend trips. Reliability garners positive remarks, with few mechanical issues over longer periods, though upkeep can become costly given the premium nature of replacement parts. As drivers become more acquainted with the digital controls, which initially might take some learning, the day-to-day use of features like the head-up display is met with ongoing enthusiasm.
