Engine And Performance
Expert Review, Pricing Analysis and Buying Guide
Any car as big and as heavy as the M850i convertible must be paired with an equally potent engine. Hauling this 4,700 pounds touring machine is a just as grand 4.4-liter twin-turbo V8 engine which churns out 523 horsepower and 553 lb.-ft. torque. The engine sends power to all the four wheels of the car via an 8-speed automatic transmission which is smooth and shifts effortlessly.This driver's car won't force you to sacrifice comfort. It's just as pleasing to take on an empty curvy road aggressively as it is to cruise leisurely on a weekend getaway.

Engine and Transmission
The M850i borrows its engine from the M5 saloon but doesn’t make the same kind of power. Nonetheless, the M850i’s 4.4-litre twin-turbo V8 is impressively refined and responds well to accelerator inputs.The 4.4-litre engine works all the wheels of the M850i with the help of 8-speed automatic transmission. This detuned iteration of the M5’s engine still makes 523 hp and 553 lb.-ft. torque. The M850i may appear silent as it begins to roll, but put in full throttle and its rumble will make you mistake it for an authentic muscle car.
It’s smooth and relatively swift to respond to accelerator inputs, with only a short delay between pressing the pedal and feeling the turbos spin up and blasting you down the road. So, not only is it effortless to drive but, with the added traction of xDrive four-wheel drive, you can also deploy all 523bhp with virtually no drama when the road opens up.

The M850i despite its pretty massive dimensions gets off the mark eagerly. It takes the M850i as little as 3.8 seconds to reach the 60 mph mark from a standstill. This quick acceleration results from peak torque being achieved at only 1,800 rpm. Also, the all-wheel-drive mostly sends a majority of the engine’s power to the rear wheels. In fact, the M850i only gets quicker while chasing quarter miles.

The brakes on the BMW M850i are firm and return ample feedback to inspire confidence under panic braking. The 2020 M850i managed to stop in 107 feet from a speed of 60 mph. It is quite impressive for a car that is as big and weighs as much as the BMW M850i.

Ride and Handling
Driving the M850i in and around the city may not be as rewarding as throwing it on challenging roads. The aggressive yet smooth shifts from the 8-speed automatic offer tremendous flexibility to the M850i.The M850i comes equipped with four-wheel-steer. This reduces the overall effort on steering and makes low-speed manoeuvrability incredibly easy. The feedback from the electric power steering wheel feels quite accurate and responsive. The all-wheel-drive offers plenty of traction due to its limited-slip differential at the rear axle. As a result, the M850i handles very well even in wet conditions.
The amount of body roll is subdued, and at the same time, the ride doesn’t feel harsh at all. All thanks to the M850i’s adaptive suspension. Naturally, this big BMW is no McLaren Roadster or Porsche 911 Cabrio. But in its class, it might be difficult to find anything as capable or as finely balanced as this. The differences in driving dynamics to the Coupe are hardly noticeable. Without any direct comparison, the Cabrio feels minimally bulkier at the limit but stays on a very high, pleasant driving level.
2020 BMW 8 Series Fuel Economy
The mileage of the twin-turbo V8 isn’t as wonderful as its performance. Also, it suffers a bit because of its heavy weight. This BMW does not even feature an engine start/stop feature to make it more fuel efficient. It returns a combined EPA rated economy of 20 mpg. It isn’t all that impressive, but is also not a big let down considering other cars in this class.

Seating and Comfort
The 8 series blissfully combines comfort with performance. The logically laid out controls are its biggest asset. Space in the front row is ample for long-distance touring. However, the same cannot be said for people taking the back seat.Speaking of seats, they can be a bit restricting for large passengers. The front seats are heavily bolstered to counter the effects of cornering and the rear seats are less than comfortable. So it’s quite a fabulous place for a couple of people to be in, but it fails to deliver on the promise of being a four-seater.
The suspension setup can be adjusted depending on the kind of feedback required. In Comfort mode, the adaptive dampers soften up to absorb the nastiest of bumps on the road. While the Sport mode toughens things up for a more controlled ride. The difference is clearly noticeable. Though, the ride quality is pretty rewarding in the later still.The level of insulation in the 8 series is just bang on. You will not hear anything you don’t want to. There’s hardly any wind or road noise making its way inside. The only sound you can probably detect is the burly exhaust of this BMW’s V8.

The BMW 8 series just excels when it comes to convenience and utility. The M850i surprises with its 14.8 cubic feet trunk, which is bigger than that of its competitors. The low liftover height and the remote seatback releases add to the overall practicality. In addition, there are several strategically placed pockets, bins and cupholders to provide adequate space for your personal belongings.

The 2020 BMW 8-series throws its styling weight around.- Car Connection
The BMW 8 series is pretty proportional for its class. Its dimensions are in tune with its performance V8 engine. As it also doubles as a grand tourer, it is significantly long and wide. A substantial weight of well over 4,700 pounds ensures the kind of stability and control required for touring as well as on the track. The 2020 BMW 8 series is the biggest convertible ever made by BMW. It’s low, wide and long design give it an American muscle car-like stance. It sports the trademark BMW twin vertically ribbed grilles which efficiently mask its long front end. In fact, it turns the unusually long bonnet into a huge visual asset.
The doors are sculpted, also to make the M850i look lighter than it is. The very interesting X-shaped rear end which houses the exhaust pipes and brake ducts merge impeccably with the front. In all honesty, the convertible with its top-down looks all the more attractive.

2020 BMW 8 Series Convertible vs. Porsche 911 Carrera 4S Cabriolet
The BMW M850i simply dominates the 911 Carrera in all considerable aspects. It can accommodate more people and has a bigger trunk.

But this BMW comes at a price tag that’s almost half of what the Continental GT costs. How’s that for an overall well packaged performance tourer?
