If you’re looking for a luxury-performance convertible or 4-door coupe with a proven track record, the 2018 BMW 6 Series cars deserve consideration. The 6 Series is more reasonably priced than some European competitors, yet despite its age, can still run circles around many of them.


BMW’s 2018 6 Series doesn’t offer anything you can’t find in newer, less expensive BMW 4 Series convertible, Audi S5 or Lexus RC F Sport. Those needing a modicum of rear-seat room won’t find it in the 6 Series Convertible.

What's New For 2018

The 2018 BMW 6 Series Coupe is dropped, leaving the Convertible and Gran Coupe Sedan. The M Sport package gains the carbon-fiber trim from the M6, and 20-inch bi-color M wheels are now available.

2018 BMW 6 Series Expert Review

The 2018 BMW 6 Series offers luxury buyers a choice between a performance-oriented convertible and a performance-oriented sedan. The 6 Series Convertible does battle with the Jaguar F-Type, Porsche 911 Cabriolet and Audi S5, while the 2018 BMW 6 Series Gran Coupe offers a coupe-like silhouette with the convenience of four doors similar to the Mercedes-Benz CLS and Porsche Panamera. BMW’s aging 6 Series for 2018 can’t quite match newer models from Jaguar, Infiniti and Mercedes-Benz, but it remains an important part of BMW’s overall portfolio, especially in convertible form. As an all-new 6 Series is on deck for 2019, buyers can expect dealers may be anxious to move models off the lot.

Driving the 2018 BMW 6 Series

Whether driving the open-air 6 Series Convertible or the thrilling M6 Gran Coupe (reviewed separately), the 2018 BMW 6 Series never disappoints. The 6 Series cars provide differing levels of power and suspension tuning, allowing for a completely unique driving experience. Powering the 640i is a smooth and responsive 6-cylinder engine that motivates the 6 Series to 60 mph in just about five seconds. The 650i ups both power and price, with a potent V8 engine outdone only by the high-performance V8 engine found in the M6 Gran Coupe. BMW equips the 6 Series with its Driving Dynamic Control that allows for various settings from Comfort to Sport+, the latter permitting the driver to adjust transmission shift points and firm up the suspension when a more aggressive driving style is required. Despite its size, the Convertible’s passenger compartment remains rather snug.

Favorite Features

In the 2018 BMW 6 Series Gran Coupe, you get the look of the old M6 Coupe with the convenience of four doors and a usable rear seat. Want more power and better handling? Step up to the 650i xDrive.

The 1,200-watt Bang & Olufsen sound system inside the BMW 6 Series is nothing short of amazing. With sound flowing through 16 individually amplified speakers, you’ll hear every note with eardrum-piercing clarity.

2018 BMW 6 Series Interior

The 2018 BMW 6 Series includes an attractive and functional steering wheel with numerous controls and a touch-sensitive iDrive controller that rounds out an already complete cockpit. With premium materials everywhere, exquisite fit and finish, wood or carbon-fiber accents, a high-end audio system and supremely comfortable driver's seat, BMW’s 2018 6 Series leaves a lasting impression. Not surprisingly, rear-seat room is tight in the convertible models, but acceptable on the Gran Coupe. Trunk space is largely unaffected when the convertible's top is folded.

2018 BMW 6 Series Exterior

The recently redesigned nose on the 2018 BMW 6 Series is subtly effective, with the number of vertical bars in each "kidney" now nine instead of 10. The rear end looks menacing when viewed head-on, which is just as it should be. But whether you choose the Gran Coupe or Convertible, a 6 Series boasts an athletic profile, defined by a long hood and a striking crease that's nearly the length of the body.

2018 BMW 6 Series Standard Features

As one of BMW's higher-end models, the base 6-cylinder 2018 640i Convertible and Gran Coupe come very well-equipped with leather and wood inside, xenon headlights, a navigation system with 10.2-inch display and touch-sensitive iDrive controller, dynamic cruise control and rearview camera. A new 650i adds a V8 engine, along with even softer Nappa leather, 20-way-power front seats, 19-inch wheels and a 12-speaker/500-watt audio system. BMW 6 Series xDrive models offer all-wheel drive, and all BMWs offer four years or 50,000 miles of scheduled maintenance.

2018 BMW 6 Series Options

While there are stand-alone options like all-wheel drive available for BMW’s 6 Series for 2018, most of the desirable upgrades are divided into packages. An Executive Package adds ventilated front seats, soft-close doors and a futuristic head-up display that projects travel information onto the windshield so you can focus on the road. Definitely get the wonderful Bang & Olufsen sound system, and performance-minded drivers should check out the active steering and Adaptive Drive. The Black Accent package adds high-gloss black trim on the grille and interior trim, black tailpipes, bi-color 20-inch alloy wheels, and black Nappa leather.

2018 BMW 6 Series Engine

Two engine options tempt prospective BMW 6 Series buyers. The 640i gets a turbocharged 3.0-liter inline-6 that makes a robust 315 horsepower, while the 650i gets a 4.4-liter twin-turbo V8 engine that puts out 445 horsepower. The 640i and 650i use an 8-speed automatic transmission, with either rear- or all-wheel drive (RWD, AWD). To save on its thirst for premium fuel, the 2018 BMW 6 Series uses auto start/stop to cut engine power at idle.

3.0-liter turbocharged inline-6 (640i, 640i xDrive)
315 horsepower @ 5,800-6,000 rpm
330 lb-ft of torque @ 1,400-4,500 rpm
EPA city/highway fuel economy: 19/28 mpg (AWD convertible), 20/29 mpg (RWD Gran Coupe and convertible), 19/28 mpg (AWD Gran Coupe)

4.4-liter twin-turbocharged V8 (650i, 650i xDrive)
445 horsepower @ 5,500-6,000 rpm
480 lb-ft of torque @ 2,000-4,500 rpm
EPA city/highway fuel economy: 17/25 mpg (RWD convertible, Gran Coupe), 16/25 mpg (AWD convertible, Gran Coupe)

How Much Does the 2018 BMW 6 Series Cost?

The Manufacturer’s Suggested Retail Price (MSRP) of the base 2018 BMW 640i Convertible undercuts some of its more lofty competition, but $86,095 -- including the $950 destination charge -- is still serious coin. If you want a V8 engine, you'll be looking at nearly $97,500. The 4-door Gran Coupe drops that price to $80,795 for the V6 and $92,195 for the V8. Want all-wheel drive? Add another $3,000. Options inflate the price quickly, and it's not hard to get to six figures. That said, the 2018 6 Series is competitive against cars like the Mercedes-Benz E-Class coupe, and it seriously undercuts cars like the Porsche Panamera and Maserati GranTurismo. Before buying, be sure to check the Fair Purchase Price to see what others in your area are paying for the BMW 6 Series. Long-term resale value should be about the same as a Mercedes-Benz E-Class Cabriolet, but lower than an Audi S5.

2016 BMW 6 Series

"Awesome performance but poor reliability"

Awesome performance, great street presence
Electronics not protected
600BHP and yet as easy to drive as a regular saloon. I never once felt out of control even deploying the full power of this remarkable engine. Exterior in green looks great and the Alpina tweaks really enhance the appearance of the 650i on which it is based. Front air dam is low to the ground and prone to scuffing but this is true of almost all high performance cars. My favorite design touch is the Alpina crankshaft and carburetor logo on the steering wheel. Two weaknesses that I have experienced. The Alpina wheels are not robust - I have had to replace two as a result of pot holes. More seriously - the main electronics are situated under the trunk and not well protected. I had a water bottle leak in the trunk and got a cascading series of random failure messages such as steering malfunction, drive train malfunction etc which the dealer traced to water having penetrated the electronics. The repair was 7000. This is a crazy design and it cant be hard to fix with some sort of cover to protect the electronics.Read less

Minnesota 650i
2012 BMW 6 Series

"Great second or third car."

Great driving experience. Still turns heads
I don't like where the interior door pull is.
This is my second 650i and (2008,2012). I have owned 8 in the last 15 years (325i, 325xi,z3,z4, x3, x5, and the 650's) This car is sneaky fast with the 400hp twin turbo. I have the heads up display...worth every dollar. Fan of the old style trunk on the 2008 better, however every detail of the car in 2012 is better, faster. I use the 650 as a daily commuter in Minneapolis from April-November and have a QX80 as a winter 4x4. The exhaust note in sport or sport plus is worth the lower mpg. I did get 28 mpg on a 1,200 trip this summer. Average is around 17 for daily driving. Lets face it you are not buying this car for mpg. Navigation screen is great easy to use and see. Back seats are for a bag...or really small adults. Pretend it is a two seater only and you will be happier. I can fit two full sets of clubs in the trunk with the top down. It does take a few tries to get the right fit. I am 6-1 and 220 lbs and I have no problem in the front seats. The seat massage is disappointing. Very limited to quads. Would expect the full back for a list price of more than 100k. Both pdc cameras are great. Makes it easy to get in and out of tight ramps. Finally analysis, great two adult car with clubs, don't drive in snow, ice or even heavy rain. Great rush every time you push the accelerator while not having the harsh M ride in traffic.Read less

2012 BMW 6 Series

"Great looking car and it's a BMW but......"

Good power and looks good, especially with the top down
Run flat tires ruin the driving experience
You would think this would be an awesome car and it is from a looks standpoint but there are some issues. It's frequently in the shop for repairs but the worst part are the run flat tires. This car should be a fun to drive machine, but the hard sidewalls on the run flat tires take away from the maneuverability, cornering capabilities and they create a harsh ride even when the vehicle is in the "comfort" mode. Most BMW's no longer come with a spare or even a canister like the M class or an AMG would, so you are either stuck with sucking it up and going with the run flats or taking your chances. It should be noted that the BMW dealerships will not put on anything but a run flat, so if you want something else, you will need to find somewhere else that will do the work. One additional note, after buying a new set of run flat tires from the dealership, I had 3 flat tires in the 5 week period following installing the new tires.Read less

"A luxurious rocket ship"

There is no car out there that combines performance and luxury better than the BMW 650i Gran Coupe. I absolutely love my car and I couldn't be happier with my purchase.
