Which 6 Series does Edmunds recommend?
Edmunds' Expert Review
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.
Trim levels & features
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.
Features & Specs
Our experts’ favorite 6 Series safety features:
- City Collision Mitigation
- Alerts you about potential collisions with a vehicle or pedestrian in front of you at low speeds, and can automatically apply the brakes.
- Night Vision with Pedestrian Detection
- Detects pedestrians in front of the car at night. Can also display the night-vision camera through the entertainment screen.
- Lane Departure Warning
- Lets you know if you're drifting out of your lane unintentionally (you didn't use your turn signal).
For shoppers in the market for an upscale convertible that combines elegant style, a luxurious interior and solid performance, the 2018 BMW 6 Series is worthy of serious consideration. Available with rear-wheel or all-wheel drive, a choice of two engines and a variety of packages and options, the 6 Series is well positioned to meet the needs of buyers sifting through the choices in a relatively narrow yet highly competitive market segment.
The 6 Series was revamped in 2016 with new front and rear fascias, restyled LED headlights and new standard equipment. Changes to the model last year were minor but included an update to the BMW iDrive infotainment system. For 2018, a new M Sport package offers carbon-fiber trim and 20-inch wheels unique to the option.
Premium materials are used throughout the 6 Series' interior, and these combine with an attractive design, well-placed controls and a wealth of standard comfort and convenience features to provide occupants with an engaging and comfortable environment. Those in the front seats are treated to plenty of leg- and hiproom, although backseat passengers will likely find the accommodations cramped.
In standard trim, both the 640i and 650i come extremely well equipped with a host of interior, exterior and driver-assist features, such as leather seats, automatic headlights and a rearview camera. Optional packages and accessories allow buyers to customize their BMW with their choice of comfort, convenience and technology features. As with most BMWs, technology remains a hallmark, exemplified by the standard 10.2-inch color display and available safety systems such as frontal collision warning and automatic braking.
A turbocharged 3.0-liter six-cylinder engine is standard power for the 640i, generating 315 horsepower and 332 pound-feet of torque. Stepping up to the 650i gets you a turbocharged 4.4-liter V8 that produces 445 hp and 480 lb-ft of torque. Both engines come mated to an eight-speed automatic transmission.
On the road, the 6 Series is best when used for cruising. Although a rigid chassis design and advanced active suspension provide above-average handling ability, the 6 Series is clearly intended for comfortable touring rather than track-day handling. But performance from the two available engines is a major plus. The standard six-cylinder engine is capable of more than enough acceleration for most drivers, but those looking for some extra zip will want to test-drive the 650i with its more powerful V8. Let Edmunds help you find the right 2017 BMW 6 Series model that best suits your needs.

Should I lease or buy a 2018 BMW 6 Series?
Is it better to lease or buy a car? Ask most people and they'll probably tell you that car buying is the way to go. And from a financial perspective, it's true, provided you're willing to make higher monthly payments, pay off the loan in full and keep the car for a few years. Leasing, on the other hand, can be a less expensive option on a month-to-month basis. It's also good if you're someone who likes to drive a new car every three years or so.
