What’s new

The BMW M6 convertible enters 2018 without any significant changes.

Vehicle overview

Analyzed logically, the 2018 BMW M6 seems excessive, absurd even. Do you really need a big, two-door convertible that can accelerate from zero to 60 mph in 4.3 seconds? Well, no. But this level of automobile surpasses need and plunges straight into the heart of desire.

Cost to Drive^{Cost to drive estimates for the 2018 BMW M6 2dr Convertible (4.4L 8cyl Turbo 7AM) and comparison vehicles are based on 15,000 miles per year (with a mix of 55% city and 45% highway driving) and energy estimates of $4.49 per gallon for premium unleaded in Maine.}

As with other BMW M cars, the M6 starts off as a more common car from the lineup — in this case, the 6 Series convertible — and then gets the full M performance division treatment. That includes an immensely powerful turbocharged V8, an upgraded suspension, stronger brakes, and just enough styling flourishes to make the car stand out.

Even in base form, the M6 convertible is stunningly fast for a car of its size and weight. Add the 40 additional horsepower available in the Competition package and the optional carbon-ceramic brakes to crank it up even more. A raft of other options — including different wheel designs, heated rear seats, contemporary driver aids, special interior trim and even a manual transmission — offer an impressive level of personalization.

The M6 convertible's well-insulated fabric top also keeps wind noise mostly at bay. And with the top down, the separate glass rear window can be raised to serve as a wind blocker, facilitating civilized conversation and preserving hairstyles to a degree.

Why so much power and performance in a big convertible like this? The better question is: Why not? If it's practicality you want, there's the M6 Gran Coupe with its four doors. If it's economy you're seeking, the regular non-M-badged 650i convertible provides prodigious 445 horsepower for thousands less. There's no rational explanation for why you'll need the M6 convertible, which is all the more reason to want it.

Edmunds' Expert Rating

Analyzed logically, the 2018 BMW M6 seems excessive, absurd even. Do you really need a big luxury convertible with up to 600 horsepower that can accelerate from zero to 60 mph in 4.3 seconds? Well, no. But this level of automobile surpasses need and plunges straight into the heart of desire.

Driving

It resembles other 6 Series cars, but its massive twin-turbo V8 thrust, broad torque range and lovely exhaust note reveal it as true M car. It's easy to drive at slow speeds or in rocketship mode, but its bulk and heft feel out of place on narrow, winding roads.

Acceleration

In its sharpest drive settings, this car is a fire-breathing beast that snorts and snarls with uncommon aggression. Yet the acceleration won't terrify you since it's accompanied by a refined stability control system. BMW says zero to 60 mph takes just 4.3 seconds.

Handling

The M6 has plenty of grip but offers so little steering and suspension feedback that it's difficult to find and drive the car at its limits. Bulk and mass also hinder the M6's ability to handle like a precision instrument.

Drivability

With adjustable drive settings, an adaptive suspension and an optional manual transmission, the M6 is equally suited to the daily commute or a full-speed romp. There's no avoiding the M6's mass, however, so agility takes a back seat to the car's exhilarating acceleration.

Comfort

The adaptive suspension, adjustable steering and throttle settings, excellent seats and luxury interior appointments make for a car that is supremely comfortable regardless of road surface.

Seat comfort

The front seats give excellent support for both long trips and short, spirited routes. The standard seats are comfortable for drivers of all sizes. The back seat is OK but lacks headroom and legroom.

Interior

The M6 has a driver-centric and stylish design. The dash joins gracefully with the large center console for a wraparound feel. Intuitive controls, excellent materials quality.

Utility

With just 12 cubic feet of trunk space, the M6 Gran Coupe isn't a particularly useful car, unless your primary use is simply driving blazingly fast. But the split and folding rear seat and center pass-through help with longer, bulkier objects.

Technology

BMW's iDrive set the bar for multiple imitators, and for good reason. The controls are easily accessible and easily navigable while driving, especially when paired with the 10.2-inch display. New additions for 2018 include onboard Wi-Fi connection and wireless device charging.

Audio & navigation

A navigation system with a 10.2-inch display comes standard. Outstanding power and clarity with either the Harman Kardon or the Bang & Olufsen sound system.

Smartphone integration

Mobile phone connection enables access to ConnectedDrive services through the display screen (Google search, route planning, travel and news information, among other conveniences). Apple CarPlay is optional, and there's no support yet for Android Auto.

Driver aids

Standard aids include a rearview camera, adaptive cruise control and parking sensors. More desirable features — front collision, lane departure, blind-spot warning systems; top-view cameras; and night vision — are available via option packages.

2018 BMW M6 models

The 2018 BMW M6 is a high-performance luxury convertible available in a single trim level. It stands apart from other 6 Series convertibles with sporty elements such as unique front and rear fascias, quad tailpipes and a range of other equipment. Under the hood is a turbocharged 4.4-liter V8 engine (552 horsepower, 500 pound-feet of torque) paired to a seven-speed, dual-clutch automatic transmission or a six-speed manual transmission.

From there, the M6 convertible adds 19-inch alloy wheels, adaptive suspension dampers, a limited-slip rear differential, adaptive LED headlights, front and rear parking sensors, automatic wipers, automatic soft-close doors, auto-dimming side mirrors with heating, keyless entry and ignition, heated power front seats, driver-seat memory settings, leather upholstery and trim, a power-adjustable steering wheel and carbon-fiber accents.

Also standard are Bluetooth, adjustable drive settings, BMW's iDrive interface (with a 10.2-inch display), a rearview camera, voice controls, a navigation system, wireless device charging, a USB port, and a 16-speaker Harman Kardon surround-sound audio system with HD and satellite radio.

The M6 convertible's Executive package adds a heated steering wheel, ventilated and massaging front seats, and a 16-speaker Bang & Olufsen audio system. The Driving Assistance package features a lane departure warning system, blind-spot monitoring, a forward collision warning system, low-speed collision mitigation, and a head-up display. The Parking Assistance package adds side- and top-view parking camera views.

For more power (or if you want to take your M6 Gran Coupe to the track), you can get the Competition package that increases engine output by 40 hp. It also includes lightweight wheels; revised tuning for the suspension, steering and rear differential; retuned stability control that provides a higher threshold for intervention in the M Dynamic mode; and a black chrome finish for the tailpipes.

Stand-alone options include an alternative 20-inch wheel design in silver or black, carbon-ceramic brakes, a beige convertible top, Apple CarPlay compatibility, and an infrared night-vision system with pedestrian detection.

Need for Speed

Richard B., 09/15/2015

2016 BMW M6 2dr Coupe (4.4L 8cyl Turbo 7AM)

This car is a rocket on wheels. So fast, yet so refined. Smooooottthhhhh, almost too smooth. You step on it at 70 mph and hang on. The most powerful car I have ever driven. The scary part is how safe you feel at ultra high speeds. You feel like you are going 55 mph at 100 mph. The craftsmanship in the interior of this car is second to none. Beautiful carbon fiber and the heads up …

Unbelievable

fdjp611, 08/15/2012

2013 BMW M6 2dr Convertible (4.4L 8cyl Turbo 7AM)

Prevously I owned a 2009 M3. The new M6 convertible is light years ahead. Nothing on the market compares to the M6 for the cost of this vehicle. Comfort, styling, options and power, it has it all. This car will be hard to top in 7 years when it's re designed again, but I will be there to get it! If you can afford it BUY IT, if you can't afford it test drive it.

Simply Spectacular

Ramctjr, 07/11/2016

2016 BMW M6 2dr Convertible (4.4L 8cyl Turbo 7AM)

After 8 months, the technical brilliance of the M6 continues to overwhelm. The vehicle design is stunning, top up or down, and the views from all sides always bring a smile and a thumbs up from onlookers. The 575 HP produces startling acceleration and the instant choice between automatic and paddle lets you control as much as you like, with the manual so much fun that you feel like a kid …

Once you go M6 you will never go back

2013 BMW M6 2dr Convertible (4.4L 8cyl Turbo 7AM)

Safety

Our experts like the M6 models:

Night Vision with Pedestrian Detection: Uses thermal imaging to detect objects at far distances. Issues visual and audible warnings; primes brakes in case of imminent collision.
Active Protection: Monitors driver attentiveness and, in the event of a possible collision, pre-tensions the seat belts and closes the windows.
Active Blind Spot Detection: Issues a visual warning in side mirror when a vehicle enters blind spot. Vibrates the steering wheel in case of potentially unsafe lane change.
